GEAR

What is Gear ?

 Gear is a toothed cylindrical or roller-shaped element of a machine that meshes with another toothed cylindrical element to transmit power from one shaft to another. It is primarily used to obtain different torque and speed ratios or to change the direction of the driving and driven shaft.

There are several other power transmission tools like belt drives, chain drives, rope drives, etc., but the main advantage of the gear system is that there is almost negligible or no slippage between the driver and the driven member. Gears are primarily used wherever there’s a short distance between the axis driving and the driven shaft, like a bicycle, motorcycle, car, etc.
