Gear Drive

Gear drives are uniform translation gears. The rotary motion is transferred from one shaft to a second through positive transmission by gears.
The gear is the element of a machine that transmits and transforms motion. A gear comprises at least one drive, an output and a frame.
The drive and the output shaft are arranged in parallel. Planetary gears are a type of spur gears, in which the drive and the output shafts are on the same axle.  In spur gears, the gears are mounted on parallel axles.
