Couplings transmit power from one shaft to another. The input shaft connects to the power source. The output shaft connects to the destination. There are two primary types of couplings.
Rigid couplings align the shafts with each other. Perfect alignment reduces wear on the machine. Rigid couplings maximize performance and efficiency. Sleeve-style couplings are the most common rigid couplings.
Sometimes the shafts do not meet perfectly. Flexible couplings transmit power without perfect alignment. Beam couplings are cut in a spiral shape. These can accommodate several degrees of shaft offset. Flexible couplings help reduce noise and unwanted vibrations.

A gear is a machine component with Gear teeth. Gear teeth mesh together to transmit torque. When two gears engage, they form a gearset. The driving gear is called a pinion.
The simplest type of gear is a spur gear. Its teeth may project towards or away from the center. Angled helical gears mesh more smoothly than spur gears. Some helical gears have just one continuous tooth. These are called worms. A worm pairs with a worm gear.
Sometimes, gears convert rotational motion to linear motion. Rack and pinion gears serve this purpose. In other cases, a machine transmits power at an angle. This requires bevel gears.
