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 uplO

950 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 parts

and 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 computer

software programmes has been finalised keeping the most favourable ratio distribution and the no. of teeth, module, helix angle, face width combination in order to

achieve 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 to

the shaft diameter of the prime mover.

DESIGN FEATURES

Gears

Single 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 case

hardening alloy steel. This ensures high standards of accuracy to relevant ISO I DIN I AGMA standards to achieve quiet running characteristics. Spiral bevel

gears are produced in the most modem Bevel generating machines and finished by lapping in dedicated machines, after case hardening.

Gear casing

Gear 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 Helical

Gear 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.

Bearings

Amply 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 harmful

deflection 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.

Cooling

Depending 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 plates

Base plates can be supplied for assemblies comprising of Gear Units and foot mounted motors correctly aligned and connected by flexible couplings. Coupling guards

can also be provided. Such requirements are supplied on specific request.

Shaft mounted Gear Units I Hollow Output shaft Gear Units

Shaft mounted Gear Units can be mounted on the driven machine shaft extension by using keys or with "Shrink DiscM device. Alternatively foot mounted Gear Units

with 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 shaft

extension. 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 Units

Gear 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.

Lubrication

lubrication 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 causing

detrimental churning of lubricant are encountered, force lubrication system is provided for effective spraying of oil to the mesh points. Quantity of oil for normal

dip 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 final

and binding.Details pertaining to dimensions and rating capacities are subject to alteration without notice.Always insist for certified

drawing,which will be sent on request.
