Gear is a mechanical device that transmits power and motion
between axes in a wide era of industries. But, it can never be used as a
single device. The complete assembly involving gears and several gear
accessories like gearbox, gearmotors, axle, transfer cases, winches,
etc. are put into practical use for several applications. Gear
accessories are selected depending on the types of the gears used. A
wide range of gear accessories control the working and normal
functioning of the gears.
