Transmission Gears

TRANSMISSION GEARS

The organisation is a pioneer in the manufacture of transmission gears. They are tested and verified for
material durability, dimensional accuracy and precision. They are made out of EN 353 & 20MnCr5
material and the micro structure, hardness and grain-flow pattern are checked to withstand operational
conditions.
Features

Distortion-free Forgings isothermally annealed to give uniform structure and remove stress concentration. This treatment eliminates gear distortion. Stress-free Gear are hobbed to increased depth to eliminate stress concentration. Class I hobs are used to ensure good finish and accurate fillet size, increases the root strength. Gear tooth flanks are shaved using highly sophisticated gear shavers to remove distortion caused by heat treatment and to ensure precise gear geometrical accuracies. Hard case heat treatment in a continuous gas carburising furnace gives it a uniform hard case and the strength to withstand torsional stress. Crack-free gears undergo 100 magnetic crack detection checks.

Gear Accuracy

The manufacturing process eliminates involute form error, lead error and tooth spacing errors. Fine surface texture Sophisticated instrument checks surface finish to ensure noise-free operation; Good-fit Smooth gear operation not only eliminates noise but also retains fit between gears and casing. Dimensional conformance assures smooth engagement. Optimum transmission The main and countershaft splines are ground to close tolerances for smoother operation, effective gear engagement and transmission efficiency. Gear involute testing machine measures and records the involute profile of gear teeth.

Advantages:

An ill-fitting gear can cause damage to other components - damage that you cannot see, except in the long run Grinding noise Forcible gearing Worn-out teeth and bearing Gear change difficulties These can cause your gear to fall prematurely and increased downtime due to frequent repairs.
