Shree Gajanan Engineering And Gear Box Sales And Service

We are among the reputed organizations, highly engaged in providing an optimum quality range of Reduction Gear Box.

 A reduction gearbox (or speed reducer) is a mechanical device used to reduce the input speed from a motor or engine to a lower output speed, while increasing the torque proportionally. It consists of a set of gears arranged in such a way that the input gear (driven by the motor) drives a larger gear or series of gears to reduce speed.

Key Components:

• Input shaft: Connected to the motor or power source.

• Gears: Can be spur, helical, bevel, planetary, or worm gears, depending on the design and application.

• Output shaft: Delivers reduced speed and increased torque.
