A gear drive drive requires two gears for operation. The two gears are spur cut, and the drive equipment receives pressure from the power output. The drive equipment then transfers power to the driven gear.
Different Drive Systems
All drive systems need a drive gear. The drive equipment is the primary transfer from the energy source to the powered gear. A belt from the drive equipment to the driven equipment is a “belt powered” system. Another option may be the “chain driven” program. The “chain driven” system runs on the chain from the drive gear to the driven gear. The “gear drive” program is immediate gear-drive. The drive equipment is directly meshed with the driven gear.
Common applications
Gear drives are used in transmissions, rear ends and transfer instances; at times the drive equipment will be smaller than the driven equipment. Different gear ratios allow the transmission to change to lower or higher rpm speeds.
Automotive gear drive
Gear drives are used on automotive engines. A “gear drive” usually refers to the timing drive; it replaces the normal timing-chain with spur-cut gears. A equipment drive is well known for the “whining 
sound” it emits. The teeth of the gears mesh together as the gears switch with the rotation of the engine. This maintains the engine in time.
