IntroductionIntroductionHelical and helical-shaft mounted gearmotors based on modular assembly system enable the optimal solutions for numerous drives of low speed operating machines which cannot be resolved any more using an electricmotor.Modular system enables a great deal of gear alternatives with a minimum of both standard and type components and assemblies the system consists of.All of these gearunits are standardly produced and supplied as helical, helical-shaft mounted or - in combination with el.motors or input assemblies.The gears are distinguished by their simple coupling possibilities with electric motors as gear motors whichenable a good alignement of the electric motor shaft and first gear shaft providing a long-lasting and reliablefunctioning of the gearunits. There is no need for the motor foundation and the compactness is also better.The electrical characteristics of the electric motors intended for gears which are used at motor gears are identical with standard IEC electric motors intended for industrial purposes. Their mechanical characteristics slightly differ from standard IEC electric motors as far as their flange and shaft end coupling dimensions and reinforcedbearings are concerned.There is a possibility of mounting IEC motors with a special adapter for IEC motors (up to 200 mm shaft height, I.E. up to 30 kW) with an elastic coupling incorporated.The gearunits can also be supplied without electric motors as motorless gearunits if the subassembly B, BT is fitted to the input side of both helical or shaft-mounted gearunits.
Technical ExecutionTechnical ExecutionThe gearunits′ housings are made of grey iron, they are mechanically and thermally stable and can reduce the vibrations.Their construction is meant for continuous duty. They are determined by the max. output torque. There are two types of executions of the housings: with or without feet.The gears are made of alloyed steel by turning and milling (planing, if necessary). The desired characteristics are obtained by thermal processing and grinding of the surfaces. Cautious manufacturing and permanent controlassure high quality and reliability of different stages of transmission (according to standard series R20/3).The gear shafts are produced of plain refined steel distinguished by the best characteristics as to hardness,rigidity and tenacity.The bearings are roller bearings that make the assembly more simple and assure high carrying capacity.Lubrication by splashing oil creates the oil film between the teeth in contact eliminating the metal contact.Besides that, lubricating oil leads the thermal losses onto the housing and protects from corrosion in working and stand-still condition of the gearunit.Tightening, as a very important element when the driving security is concerned, is done by means of both high quality shaft tighteners and tightening caps which prevent the oil leakage and the penetration of the dust into the gearunit.Colouring and antirust protection is standardly performed with a basic colour onto which a finishing layer of RAL 7001 GREY colour is painted.The processed surfaces are protected with a thin antirust coating. It is possible to request some other kind of colouring and protection.
Power, Torque and SpeedPower, Torque and SpeedValues of output power greaded acording to ISO 497/73 and torque values from selection tables refer to thestandard execution, standard ambiental conditions and also standard lubrication of gearunits and motor gears.Motor output values given in tables are just orientational ones.In every single case of application the crucial parameter is the output torque at requested output r.p.m.The output r.p.m. values given in tables for the selection of the gearunits are rounded off to the standard values according to R20 series.The real r.p.m. value is attainable from motor rated r.p.m. and gear ratio, and depends on real loading andchanges of the network tension.
EfficiencyEfficiencyThe efficiency is defined mainly by rolling losses of teeth and bedding of the bearings. Depending on the number of stages of the gearunit the efficiency of the basic gearunit is between 94 and 98%. In case of a combination of basic and additional gearunit the efficiency is between 85-92%.
Gear Unit WeightGear Unit WeightSince the oil quantity depends on mounting position the gearunit masses given in the tables refer to the motor and motorless gearunits without oil filling. The oil masses are given in another table.

The following metodology refers to gearmotors and motorless gears.
Drive Selection by Service Factor DeterminationDrive Selection by Service Factor Determination
In order to make a correct selection it is necessary to have all the information cencerning the drive conditions, i.e. mechanical and thermal loadings provoked by the working machine, working regime and ambiental conditions. The precise determination of all of the important factors requires detailed calculations. The most important ofthose factors are:• Type of loading and type of the working machine• Acceleration of the masses• Number of startings per hour• Daily operating time of the gearunitIn order to make the selection of the gearunits easier we usually use, the so called, service factor summing up all the mentioned, important factors.By means of the service factor the drive selection is chosen according to the following condition:fBM≤fB, I.E.

The service factor defines the size of gearunit and not the power of the driving motor.The higher the service factor for the chosen gearunit is the lower is the loading of the gearunit i.e. its safety is higher.Knowing the motor power value: P and also the output rpm n2 and the torque T2 you can choose such a type or size of the gearunit i.e. Tmax at which the service factor condition fBM ≤ fB is satisfied.It is possible to choose a gearunit with a service factor fB < 1 in a case of quiet functioning and periodical duty (for example: S2-10min).

At extreme working conditions of the driven machine (intensive shocks, usual reversing and braking, highambiental temperature, high values of radial and axial forces, big masses to be accelerated, fa >10) necessary service factor of the driven machine, fBM >1.8.In both of the cases it is necessary to consult the factory.

Instructions for Installation, Operation & MaintenanceInstructions for Installation, Operation & Maintenance
Delivery and storageDelivery and storage
Gearunits, i.e. motorgears are checked and verified in the Dept. of final control and then delivered prepared for
running, filled up with lubricants in acordance with the desired mounting position. During warranty period the
gearunits are to be opened just with a previous authorization of the manufacturer.
In case they are not meant for an immediate functioning all machine storage should be done indoors, in dry and
dark conditions, in their own packaging material if possible.
InstallationInstallation
In order to eliminate the possible resonant vibrations during exploitation, including all the negative
consequences, a foundation stud or the supporting construction must be dimensioned in a way that the
structure own frequency can differ min ±20% from the excitation dominant frequency.
The foundation studs or the supporting constructions themselves must be able to bear extraordinary break-down
loadings.
Assembly and disassembyAssembly and disassemby
When assembling the elements of transmission to the shafts of helical gearunits do not hit but assembly carefully
using appropriate tools i.e. preheat the hub of the transmission element up to 80oC. That is the reason why the
output shaft extension execution is done with an appropriate midpoint with a screw thread.
Particular attention is to be paid to the gearunit shaft allignement with the working machine.
Example:
How to assembly the shaft mounted gearunit onto the working machine and how to disassembly it:
Assembly Work position Disassembly
Using an appropriate torque arm you can assure the gearunit from swivelling due to reactive torque.
VibrationsVibrations
A reliable and safe functioning of mechanical gearunits requires the parameters of vibration to be in accordance
with ISO 2372 and ISO/TC-60/WG-9-N55, IEC 34-14/N, and the sound power level according to IEC 34-9.
The control of the parameters of vibration according to the mentioned standards is done during testing,
periodically during exploitation and it is obbligatory after overhauling.
The torque transmission from the gearunit to the working machine could be done by means of different
couplings, chain sprockets, gears, belt pulleys. The elements of transmission up to the peripheral velocity of
20 m/s, must be statically balanced, and those with peripheral velocity over 20 m/s, must be dinamically balanced.

StartingStarting
Prior to starting it is necessary to adjust the ventilation screw on the top of the gearunit in order to enable free air
circulation. Every gearunit should be started along with the working machine first unloaded and then loaded.
It is also necessary to control the temperature and the vibrations of the motorgear housing, the buzzing and the
motor current. These are the parameters of a well selected, properly mounted and adequatly loaded gearunit.
The level of the lubricant has to be in accordance with the gearunit mounting position.
MaintenanceMaintenance
The maintenance of gearunits and gearmotors consists of
• control of gearunit and motor temperature
• control of motor current, voltage supply
• control of buzzing and vibrations
• control of oil (level, foaming, presence of water, viscosity, regreasing)
Bearings lubricated with grease must not be completely filled up in order to avoid overheating.
After 3000 operating hours (at least once in a six months) it is necessary to do the oil checkup or to change it, if
necessary.
Independently from the gearunit operating hours it is recommendable to change the mineral oil at least after two
years (not longer than 10000 h), and as to the syntetic oil the recommendable period is 4 years (not longer than
20000 h). Oils of different makes are not to be mixed up.
At gearunits the oil change is to be done at standstill and in hot driving condition. After the old has been drained
out and after cleaning the housing the new oil is being put in through the airport, up to the oil level aperture.
Up to this level also the relubricating is done, if necessary.
If it is necessary to take off the motor during the period of exploitation care should be taken not to damage the
teeth on the gearunit′s first and second gear. The first gear fitted to the gear shaft extension is taken off using
appropriate tools.
In the event of dismantling and assembly of the whole gearunit a special care should be taken to the accuracy of
the shaft seals, sealing caps and klingerit seals.
Spare partsSpare parts
When ordering spare parts, apart of the designation, it is necessary to give all the name plate data.
Spare parts sheet with the recommended substituting elements is obtainable on request.

DescriptionDescription
Double helical gearunits are applied in case it is necessary to obtain particularly low values of r.p.m.,
0.1 ≤ n2 ≤ 10 min-1.
They are constructed by coupling the basic helical (2 and 3-stage) gearunits (2 and 3-stage) gearunits. This
makes possible the following multi-stage transmissions:
4-stage by 2+2 stage
5- stage by 3+2 stage or 2+3 stage
6- stage by 3+3 stage
with the max. transmission ratio up to ie�14000.

Brake MotorsBrake MotorsThe brake motors are built out of a basic type of gear motors, ZKR.Their length is different because of the space meant for the brake.The brake gets fed by the inverter built-in into the terminal box. The inverter′s standardvoltage is of 230 or 400 V. The braking torques are adjusted to their max. values, they can be reduced to 75 or 50% of their max. value taking off 2 or 4 springs from the brake.
- Hard fan: For the brake motors the, so called, grey iron hard fans are delivered, on request. They find their application at drives which require both soft starting and soft braking (driving, lifting, etc.)
Other MotorsOther MotorsAll the other electric motors such as:- 2,6 and 8 - poles motors- Two (and multiple speed) motors with 1 winding, 4/2, 8/4, 6/4, 8/6, 8/2, 12/2 could be coupled with gearunits.- Single phase motors- Other motors, such as: motors with Eex enclosure, DC electric motors, etc.
Other Special Features:Other Special Features:Duty tupes:Duty tupes:
If S2 (duty with limited duration) and S3 (intermittent duty) working regimes are requested the motors can be
loaded with power bigger than the rated one. As to these and the other types od working regimes the choice of
the adequate type and size of the motor is to be done on a basis of the complete working conditions. All of the
above mentioned refers also to the motors running in a non-standard ambients. In those cases it is
recommendable to contact our Technical Advice Service.
Motor protection:Motor protection:
All the electric motors can be fitted with PTC thermal detectors built-in into the windings in order to realize the
complete thermal protection of the motor. A motor protective assembly is used as a protection from overloading
and two phase motor duty.
