Helical I Bevel Helical Gear Units

Introduction. Design Features

INTRODUCTION

These Gear Units are available in parallel shaft helical units in single, double, triple and quadruple reduction gear stages having a maximum output torque rating uplO950 kNm. And in right angled shaft bevel helical units in double, triple and quadruple reduction gear stages having a maximum output torque raling uplo 600 kNm.The modular design and construction of this series, offer many engineering and performance advantages induding high degree of interchangeability of partsand sub assemblies.

Design of these Gear Units, made with gearing details following addendum modification based on the latest findings of gear design with the help of latest computersoftware programmes has been finalised keeping the most favourable ratio distribution and the no. of teeth, module, helix angle, face width combination in order toachieve the optimum evenly distributed power rating in various stages and to get the highest diameter for the shaft extension of the input shaft quite comparable tothe shaft diameter of the prime mover.

DESIGN FEATURESGearsSingle helical gears, profile ground with the latest technique for tip relief and face crowning in the modem gear grinding machines are made out of NiCrMo casehardening alloy steel. This ensures high standards of accuracy to relevant ISO I DIN I AGMA standards to achieve quiet running characteristics. Spiral bevelgears are produced in the most modem Bevel generating machines and finished by lapping in dedicated machines, after case hardening.

Gear casingGear casings, created using the latest techniques of 30 modeling possess the most modern styling and the rigidity. For all Helical Gear units and For Bevel HelicalGear units sizes upto 320, are made of close grained Cast Iron to achieve favourable vibration dampening properties.Other features are:- Case design is made using the latest FEA techniques to get high strength to weight ratio.- Horizontal split case design for ease of maintenance Inspection cover provided for viewing gear contacts during maintenance shut downs.- Provision of oil level dipstick, ventilator with dust proof filler and drain plugs. Optionally oil level sight glass can be provided in place of dipstick.- Gear casing in fabricated steel construction as alternative for all Helical Gear Units and for Bevel Helical Gear Units Sizes upto 320. For Bevel Helical Gear Units

Sizes 360 and above, Casing is in fabricated steel construction only.

BearingsAmply proportioned roller bearings are used to support all the shafts. For three and four stage design, the input shaft will have shorter span to avoid harmfuldeflection on load.

Backstops (Holdback units)When required to operate on non-reversing drives, back stops can be fitted. The backstops are of centrifugal lift off type and are located on the pinion shafts.They have adequate capacities to with stand the full rated torque.

CoolingDepending on the application and rating requirement, Gear Units are cooled b~' :- Normal cooling by convection from the external surfaces of the gear case. Mechanical fan fitted to high speed shaft which is effective for either direction of rotation.- Cooling water coil fitted in bottom half of gear case, dipped in the lubrication oil sump.- Fan and cooling coil.- Separate oil cooler, used in conjunction with forced lubrication system.

Base platesBase plates can be supplied for assemblies comprising of Gear Units and foot mounted motors correctly aligned and connected by flexible couplings. Coupling guardscan also be provided. Such requirements are supplied on specific request.

Shaft mounted Gear Units I Hollow Output shaft Gear UnitsShaft mounted Gear Units can be mounted on the driven machine shaft extension by using keys or with "Shrink DiscM device. Alternatively foot mounted Gear Unitswith hollow output shaft can be mounted on a common base plate with prime mover and coupling, the complete assembly being mounted on the driven machine shaftextension. In both the types, the connection to the foundation is to be made using Torque arm. Torque arm I Shrink Disc I Base plate are supplied as optional extra,on specific request.

Motorised Gear UnitsGear Units are available as assemblies comprising standard flange mounted (B5 type) motors directly mounted on input shaft line with the use of adaptor housings.Motor and Gear Unit shafts are connected by flexible couplings. Specify the scope relevant to the requirement.

Lubricationlubrication in most instances is by the transfer of oil to the mesh points by gear dipping in the sump of Gear Unit bottom half. Wherever high pitch line speeds causingdetrimental churning of lubricant are encountered, force lubrication system is provided for effective spraying of oil to the mesh points. Quantity of oil for normaldip I splash lubrication is given in the dimension tables. For grade of oil refer "Guidelines for Selection" sheet.

Note: As improvements in design are continually being made, the specification given in this publication is not to be regarded as finaland binding.Details pertaining to dimensions and rating capacities are subject to alteration without notice.Always insist for certifieddrawing,which will be sent on request.

If built-in cooling coil arrangement is required for HDOH I HOOD & HTOH I HTOD units,please refer to us.The cooting water can flow through the cooling coil in either direction. The connections for water inlet and outlet are therefore interchangeable.For thennal capacities of gear units with builtin cooling coil arrangement based 20C ambient temperature see respective power rating tables.For thermal ratings for ambient temperature other than 20C,use appropriate thennal service faClor,as given in page 5.
