Product Profile of Worm Reduction Gear Boxes

Gujarat Power Transmission Equipment Co offers Worm Reduction Gear Boxes. Gujarat Power Transmission Equipment Co also manufactures bearings. Worm Reduction Gear Boxes range from 1 1/8" CD to 8" centre having ratios from 5:1 to 70:1. They are available both in foot as well as flange mounted design suitable for stirrer duty application. It consists of shaft having hollow input & hollow output for various duty applications.

Specifications of Worm Reduction Gear Boxes are as following:

• Gearcase: Of neat contour and sturdily built the case is designed to provide maximum surface area for heat dissipation. Made of semi-steel, a super quality close-grained metal, it is dust-proof and oil-tight. All faces are machined and bearing housings accurately bored.

• Worm & Wheel :The worm is made from high tensile case hardened alloy steel integral With its shaft, hardened, ground and finished to precision limits The worm wheel is centrifugally cast phosphor bronze [ for the smaller sizes chill cast ] giving a dense homogeneous casting. Gear teeth are generated with precision profile ground hobs on specially designed Machines to ensure accurate tooth form.

• Full advantage has been taken of the involutes helicoids thread form with increased load capacities, designed in accordance with B.S.721:1963.

• Bearings :The worm is made from high tensile case hardened alloy steel integral With its shaft, hardened, ground and finished to precision limits The worm wheel is centrifugally cast phosphor bronze [ for the smaller Sizes chill cast ] giving a dense homogeneous casting. Gear teeth are generated with precision profile ground hobs on specially designed Machines to ensure accurate tooth form.

• Full advantage has been taken of the involutes helicoids thread form with increased load capacities, designed in accordance with B.S.721:1963.

• Cooling: Heat dissipation is effectively controlled by the large surface area, Additional cooling ribs, increased oil capacities and the improved fan and Cowl design, for fan cooled gears.

• Oil temperatures are controlled within acceptable limits.

• Lubrication: A positive lubrication system, operative with either direction of Rotation, is effective in any mounting position. All bearings are assured of an adequate supply of lubricant.

• Oil filler and breather, oil level and drain plugs are fitted and are Interchangeable for universal mounting. The quantity and viscosity of oil required is given on a date plate fixed to the case.
