Where to Install / Torque Limiter Selection

Torque Limiter Selection

Types JA, JB, & JC For release torques up to 48,000 lb in

Decide on manual or automatic reset. Choose a position as near as possible to the expected overload (see diagram).

Calculate the torque setting required at that position. This can be determined from the motor power, r.p.m. and gearing ratio to the driven load or from the maximum permissible torque for drive components such as compressive stress on keys. It is the weakest component that requires protection. Make allowance for motor starting torques (generally twice normal running torque).

Having calculated an approximate setting for the release torque, final adjustments can be made on site.

Check from tables that shaft, sprocket or pulley, etc. can be accommodated.

Selection Example

Model Type JAF7-0500

This specifies:

Manual reset clutch capable of 1000 lb ft torque complete with flexible coupling for shaft-to-shaft application.

To enable us to deal efficiently with your inquiry, we ask you to supply the following facts:-

• Type of application and environment conditions

• R.P.M. of drive

• Release torque required

• Length and diameters of shafts

• Space available between shaft ends

• Overall space available - length and diameter limitations

• Type and sizes of accessories, i.e. sprocket, pulley, etc.

• Any special requirements such as shifter flange, neoprene seals, etc.

In most drive systems there are several

alternate locations where the Brunel clutch

can be installed (fig. 1). The preferred

position is at the driven shaft. This location

places the overload protection clutch at

a point in the drive system where actual

load torque can be accurately monitored.

Alternate locations in the drive system as

shown in Figure 1 are usually subject to

greater variation in torque loads due to the

reduction ratios within the drive system. The

preferred mounting location will provide

better control of the overload release torque

thus preventing unnecessary release at

torques below safe operating levels due to

system inertia and starting torque peaks.

Reduction Gearing

When Brunel Torque Limiting Clutches are installed on large ratio reduction gear boxes care must be taken since it may not be practical to set a torque limiter mounted on the input shaft low enough to provide the proper torque protection on the output shaft. The large reduction ratio will also decrease the accuracy of the output release torque setting if the clutch is located on the input shaft.

High Inertia Drive Systems

When selecting Torque Limiting Clutches for use in high inertia drive system, the location of the clutch must be between the high inertia load (flywheel, large pulley or gear, etc.) and the driven mechanism. Locating the Brunel overload release clutch in this position will protect the driven mechanism from the large inertia forces.

Optional Features

Single Position Re-engagement

For use where timing of machine is required. Available for Type JA. (Standard on JC and JB models.)

Light Duty Springs

For systems requiring very low torque levels and greater range of adjustment sensitivity.

Single Direction Overload ReleaseFor applications where heavy braking is applied. Type JA only.

Dual Level Torque SettingFor heavy overrunning applications which require normal release torque setting in one direction and a lower torque release setting in the opposite direction. Type JA only.

Brunel Safety Element Torque Limiters

Torque Limiting Modules

Brunel Torque Limiting Modules have been

specifically designed to provide overload

protection for applications where very high

torques are transmitted and to extend the

range covered by Brunel Type JA units.

The modular system provides facilities for

virtually unlimited torque capacity and lends

itself to many transmission applications

– chain, belt and gear drives, or shaft-to-shaft

gear or flexible coupling drives.

The maximum release torque depends on the

number and size of Torque Limiting Modules

that can be incorporated, and the size of

the unit that can be accommodated within

the confines of the installation. Internally

& externally adjusted modules provide

repeatability better than ±5%, however

externally adjusted modules are preferred

when the application is required to operate

within minimal variations between static &

dynamic disengagement.

Disengaged

plunger, and once this condition is reached the flanges are completely free to rotate independently. A suitable switch can be incorporated in the assembly to switch off the drive motor or operate a warning device when the Torque Limiting assembly disengages. Resetting is a simple matter of first re-aligning the flanges X and Y and then tapping each module plunger back with a soft mallet to allow the circle of balls to return to their original position and the large steel ball to return to its location in the detent pocket.

Construction

The Brunel Torque Limiting Module is constructed from the finest quality materials. Many of the vital components are made from high quality tool steels, through hardened to Rockwell C62, and precision ground to close tolerances.

Normal Operation

The flanges X and Y are driven by a large steel ball 2, located in the detent pocket 1, which is retained by a plunger 3. This in turn is retained axially by means of a system of angled races 6,8 biased by pressure from the Belleville springs 5, acting on a circle of balls 7.

Disengagement

On overload, relative angular movement between flanges X and Y imparts a tangential force (Fu) on the large steel ball, forcing it clear of the detent pocket back against the plunger. This in turn causes the plunger to be forced through the circle of balls overcoming the spring loading on the angle races. In this position, the balls are resting on the large diameter of the

Detent Pockets

Internally & externally adjusted modules can have through hole or blind hole detents (see diagrams left and on page 5). The type of detent is dependent upon the design constraints.

All modules are required to be preloaded. In the case of the through hole module this is done by tightening the set screw at the base of the detent pocket. In the case of the blind hole module this is done by the means of shims under the module.

Selection

To apply the modules in the form of a torque limiter, it is necessary to determine the quantity of modules needed for the required torque capacity at a specific radius from the axis of rotation.

No. of Modules = MTorque (lb in) = TTangential Force = FuMounting Radius of Modules = RAD

M = T Fu x RAD

T = M x Fu x RAD

Features and Benefits

Very accurate release torque repeatability with minimal variation between static and dynamic release. Versatile installation allows for the torque limiter center section to be removed without the need to move the motor or gearbox.

Individual modules are preset to provide the required release torque. Any maintenance of the modules is a straightforward operation. A simple removal operation allows for module recalibration without having to replace the complete unit. By holding spare modules in stock already preset to the required release torque keeps downtime to an absolute minimum.

Manual reset of the torque limiter can only be carried out when the drive is at rest. Resetting is achieved by realigning the two halves of the unit and then lightly tapping each module fitted, with a soft mallet.

Lubrication of the unit is via easy access grease nipples. Proximity sensor targets are included to provide the means to switch off the drive after an overload occurs. While each torque limiter assembly is normally factory preset, if required site adjustments can be carried out, a setting chart with instructions is provided for this purpose.

Externally Adjusted Disconnect Modules

Please note a security key is required and adjustment should only be carried out by an authorized person.

• Accurate release torque repeatability

• Simple fast manual re-engagement

• Low-cost maintenance

• The preferred protection for many extruder manufacturers

Construction

The Brunel Torque Limiting Module is constructed from the finest quality materials. Many of the vital components are made from high quality tool steels, through hardened to Rockwell C62, and precision ground to close tolerances.

Normal Operation

The flange connection is driven by a large steel ball (2), located in the detent pocket (1), which is retained by a plunger (3). This in turn is retained axially by means of a system of angled races (5,7) biased by pressure from the Belleville springs (4), acting on a circle of balls (6).

On overload, relative angular movement between the flanges imparts a tangential force (Fu) on the large steel ball, forcing it clear of the detent pocket back against the plunger. This in turn causes the plunger to be forced through the circle of balls overcoming the spring loading on the angle races. In this position, the balls are resting on the large diameter of the plunger, and once this condition is reached the flanges are completely free to rotate independently. A suitable switch can be incorporated in the assembly to switch off the drive motor or operate a warning device when the Torque Limiting assembly disengages.

After first ensuring that the drive is isolated, resetting is a simple matter of first realigning the flanges and then tapping each module plunger back with a soft mallet to allow the circle of balls to return to their original position and the large steel ball to return to its location in the detent pocket.

Detent Pockets

Internally & externally adjusted modules can be through hole or blind hole detent fixing (See diagrams on opposite page). The type of detent fixing is dependant upon the design constraints.

The mechanical clearance in the Module assembly should be eliminated by pre-loading the detent pocket (1) against the driving ball (2).

Selection

To apply the modules in the form of a torque limiter it is necessary to determine the quantity of modules needed for the required torque capacity at a specific radius from the axis of rotation.

No. of modules = Torque (Nm) x 1000 Fu (N) x radius (mm) x K

K = 0.65 for General Applications.

K = 0.5 for Steelwork Applications.

Features & Benefits

Brunel Safety Element Torque Limiters have been protecting industrial power transmission systems around the world since 1971. The Extruder Safety Element “SE” Series Torque Limiters are designed specifically for the precision requirements of twin screw extruder applications. They are totally enclosed and made exclusively of steel (except coupling flex elements & seals). The wearing parts in the Safety Element Modules are D-2 tool steel thru hardened to Rc 62 minimum. Tapered roller bearings are incorporated in the design for long life, and are regreaseable through a grease fitting and grease relief valve. Modular construction provides design flexibility and simplified maintenance. Safety Elements

are precision Belleville spring loaded, single ball detent design. A unique over-center mechanism insures complete disengagement on overload and simple, fast manual re-engagement.

Safety Element Torque Limiters completely disengage on overload thus preventing damage and down time to the equipment. When applied on motor output shafts of twin screw extruder drive systems, the “SE” Torque Limiter protects the reducer and twin screws from potential damage upon overload.

Brunel Torque Limiters eliminate the problems

associated with slow reaction electrical

overload devices, shear pins which give a

wide release torque variation, or slip clutches

which may rapidly overheat.

Torque Limiters

Brunel products can save you money - the

initial cost is frequently more than covered

by the saving in down-time even on the first

overload.

• Protect plant and transmission against

overload

• Full bi-directional operation in any plane

• All metal, totally-enclosed construction

• Virtually no maintenance

• Provide years of trouble-free service

• Low Initial cost

Many of our torque limiters have been

designed and manufactured to meet

customers’ specific operating requirements.

If you have any specific requirements please

contact Brunel Corporation for assistance.

Bores and Keyways

Standard bores and keyways are manufactured to H8 and Js9 tolerances to BS4500: 1969, both in Metric and Imperial dimensions.

Maintenance

During assembly all units are packed with a 3% Molybdenum Disulphide (MoS2) grease BP Energrease L21 M. Because of their unique fully enclosed design all units need only be stripped and re-packed with grease every two years. However, under extremely adverse conditions of environment and duty please consult Brunel Corporation.

Running in Oil

All Brunel units can be run in oil if required without affecting performance.

Typical Applications

How To Select

Select Manual Reset or Automatic Reset

type overload release clutch to suit your

specific application.

Choose a position in your drive system for the

Torque Limiting Clutch. See page 2 for guidance.

Calculate the torque setting required for the

position selected.

Calculate the maximum permissable torque for the drive components after considering torsional stress in shafting, stress on keys and keyseats, torque capacity of couplings, chains, gears, belts, etc. It is the weakest component in the system that requires protection.

—or—

Determine the torque setting based on motor horsepower, drive speed and reduction ratios.

drive torque (lb ft) = horsepower x 5250

RPM*

—or—Determine the maximum permissable driven load based on conveyor belt or chain tension.*RPM - at point where torque limiter

is applied

An allowance for starting torque may be required depending on the location of the clutch in the drive. At the motor shaft, peak torque of approximately twice normal running torque is possible. At locations away from the motor, peak torques will be dampened by system inertia, tending to reduce the effect of motor peak starting torque. Field conditions will also tend to change the calculated torque values.

The best way to deal with the above variables is to make some allowance when selecting the torque setting required.

How to Select and Order

How To Order

Please supply the following information with your order:

Quantity: The number of clutches needed.

Type & model/bore and keyseat. Example: JAB7 2.00" bore with 1/2 x 1/4 Kws.

Torque Setting

When combination units are selected supply additional data as required below:

For coupling combination supply bore and keyseat for coupling and torque limiter.

For sprocket or pulley combination supply complete sprocket or pulley data.

Advise torque setting if factory setting is required.

Special requirements such as shifter ring, neoprene seals, vertical mounting, etc. must be specified.

If bore and/or keyseat sizes other than standard tolerances or shaft fits are required, please specify dimensions completely, including tolerances.

Keep in mind that each torque limiting clutch is adjustable and the final overload release torque setting may have to be adjusted on the job to meet your specific application requirements.

With the approximate torque required select the right size and type clutch.

Check the clutch selected to make sure the shaft, key, sprocket, pulley, etc. requirements of your application can be accommodated.

Technical Features

• Complete disengagement on overload

• Simple “one screw” torque adjustment

• Positive drive - no slip

• Rapid easy reset

• Torque setting maintained indefinitely

• Release action can operate a warning

device or limit switch

• Robust and compact design

• May also be used as a lever

operated clutch

Type JAB - Manual ResetRelease Torque: 10 to 4000 lb ft, 14 to 5500Nm

Bush Bearing Type JAB Ball Bearing Type JAB

For particularly dusty conditions such as

cement works we offer neoprene seals. Please

specify when ordering.

Important - Use switch plate and limit switch

to quickly shut down drive on break-out

to avoid damage to bearing. For prolonged

periods of running disengaged, ball-bearing

mounted units must be used. For higher speed

applications consult Brunel Corporation.

Application

The clutch can be installed in any drive system, safeguarding against sudden surges or gradual build-up of torque. Modifications are possible to provide manual lever operation of the clutch while retaining the overload release feature. Single direction release and one position reset can also be provided.

Normal Running

The drive is transmitted from the hub 1 through the splined ring 2 via the tapered jaws 3 to the rotating jaw ring 4 . The jaws are held together by spring pressure acting through two angled races (5 and 6 ) and a crowded circle of balls 7 located by a step on the hub.

Disengagement

On overload, the tapered jaws are thrust apart, moving the splined ring 2 and lifting the balls 7 over the step on the hub, thus instantly disengaging the drive, leaving rotating jaw ring 4 free to rotate on bearing 10.

Torque Adjustment

The release torque settings are made by adjusting the control ring 9 so altering the spring forces. The adjusting ring is locked in position by a set screw 8.

Re-engagement

To re-engage, the tapered jaws are aligned using reference marks and the sliding assembly pushed along the hub until the balls snap back into their original position. This requires no further spring compression and is easily accomplished.

For remote resetting the body can be supplied with a flange to suit a resetting mechanism. See diagram below.

Installation

Clutches can be supplied pilot bored or finish bored and keywayed. The hub may be fitted to either shaft and the flange can be connected to a flexible coupling or can carry a sprocket or pulley.

Installation

The hub is mounted on the drive shaft of the PTO using a push fit and key. When installing, do not hammer the flange face 1. Mount universal joint to flange using socket head screws.

Release Torque Setting

The clutch can be supplied set to your specified torque. To increase the setting, turn the adjusting nut 2 clockwise; to decrease, counterclockwise. Do not unscrew beyond the flush position where the zero marks coincide.

Technical Features

• Prevents Expensive Transmission Damage

By Automatically Disengaging On Overload

• Simple Adjustment

• Easy Reset

• Flange Mates With Standard Series

Universal Joints

• Maximum Speed 3000 rpm

• Grease Lubricated

• Release Torque Adjustable Up To 560 Ib ft

Maximum

• Fully Sealed Against The Environment Of

A PTO Drive

To Reset

When the clutch operates and disengages the drive, first locate and clear the cause of the overload. To reset, rotate the flange 1 to align the raised screw 3 in the housing with the set screw 4 in the hub. Hold the flange and, with a pry-bar, turn slightly in the direction of the arrow.

Maintenance

Clutches are grease-packed on assembly with a molybdenum disulphide base of grease. A grease fitting is provided for routine maintenance.

Consult Brunel Corporation.

2 Tolerance on spigot diameter B is F7 to

BS 4500:1969.

3 For higher release torques use Type B

on page 34.

4 Standard tolerances on keyways is JS9 and

on bores H8 to BS 4500:1969.

5 Applicable to all variants.

Normal Running

The drive is transmitted between the hub flange 1 and the housing 2 by the balls 3, spring-loaded into the pockets on the flange face.

Disengagement

On overload, the balls are displaced axially through the housing, further compressing the springs. Once out of their pockets, the balls roll on the face of the hub flange for one revolution before re-engaging and synchronizing the drive.

Torque Adjustment

The release torque is set by tightening nut 4 thus increasing the spring pressure. After setting, the nut is locked with a set screw and plug.

Installation

Clutches can be supplied pilot bored or finish bored and keywayed. The hub may be fitted to either shaft and should be located against a shoulder to resist the resetting spring force and locked by means of set screw in the hub flange. The drive flange may be replaced by a sprocket, pulley, etc., or connected to a coupling. See pages 31 and 32.

Application

This type of protection is ideally suited to drives such as wrapping and packing machinery where it is essential to restart in the correct sequence and where access for manual resetting is not available.

Type JC clutches should always be used with

a limit switch to bring the drive to rest within

a few revolutions thus preventing possible

damage by continual releasing and resetting.

· From the continuous Power (Hp) and operating Speed (Rpm) calculate the Application Torque TNORM from the formula:

TNORM = 63,025 x (Hp/Rpm) lb-in

· Select Prime Mover Service Factor (Fp) from table.

· Select Driven Equipment Service Factor (Fm) from table.

· Calculate TMAX from the formula:

TMAX=TNORM (Fp + Fm)

· Select Torque Limiter such that TMAX < Torque Limiter Maximum Setting.· Check Rpm < Torque Limiter Maximum Speed (from catalog data).

· Check Torque Limiter Bore Capacity such that dmin < d < dmax.

· Consult the factory for alternatives if catalog limits are exceeded.


Selection Procedure

TNORM = Application Torque (lb-in)

TMAX = Peak Application Torque (lb-in)

Hp = Continuous Power to be transmitted by torque limiter (hp)

Adjustments under this warranty will be made only after completion of inspection of the part or product in the factory. Liability under the warranty shall extend only to the replacement or correction of any part or product determined by Brunel Corporation inspection as not conforming to this warranty. All materials must be returned freight prepaid.

This warranty shall not apply to any product which shall have been repaired or altered without the manufacturer’s knowledge and consent or operated or installed contrary to instruction or subjected to misuse, improper maintenance or damaged by accident or negligence.

This warranty is made in lieu of all other warranties, express or implied, including merchantability or fitness for a particular purpose, and there are no other warranties that extend beyond this express warranty.

Brunel Corporation reserves the right to discontinue models or to change specifications at any time without notice. No discontinuance or change shall create any liability on the part of Brunel in respect to its products in the hands of its customers or products on order not incorporating such change even though delivered after any such change.

Rotating equipment is potentially dangerous and should be properly guarded. The user should check for all applicable safety codes in his area and provide a suitable guard.

Performance Assurance

Rated torque and speeds of Brunel Corporation products are provided in current catalogs to assist the buyer in selecting the proper Brunel Corporation product. In addition, application assistance is offered by Brunel Corporation for guidance to the buyer in selection of a catalog product and application of custom designed products. Since the actual performance characteristics of all Brunel Corporation products in the buyer’s application are the responsibility of the buyer, performance assurance is usually accomplished through manufacture of a prototype by Brunel Corporation, and a test or qualification program on the part of the buyer.
