Gearing products (components or housed gearboxes) are mechanical devices used to increase the output torque or change the speed (RPM) of a motor. They are also used for inertia matching between a load and a motor. The most common type of gearing product is a housed gearbox (or housed gearhead). Gearboxes come in a variety of types: Plantary reducer, Strain Wave Gears, Bevel, Helical, Spur, Cycloidal, etc.

Most gearboxes are constructed from steel materials such as iron, aluminum and brass, however spur gearboxes can also be made with plastics such as polycarbonate or nylon. The orientation of the gear teeth plays a major role in the overall efficiency, torque and speed of the system. Straight gear teeth gearboxes are typically used in low-speed applications. These gearboxes can be noisy, and usually have lower overall efficiency.

Helical gearboxes are typically used in high-speed applications. These gearboxes are quieter in operation than straight gear teeth gearboxes and usually have improved overall efficiency. In very low noise applications, ceramic gears can be used to replace metal

gears

In mechanical engineering terminology, backlash, sometimes called lash or play, is the measurable lost motion in a mechanism caused by gaps between the parts. An example in the context of gears and gear trains is the amount of clearance between mated gear teeth. It can be seen when the direction of movement is reversed and the slack or lost motion is taken up before the reversal of motion is complete.

Depending on the application, backlash may or may not be desirable. Reasons for the presence of looseness or "play" in mechanical linkages that cause backlash include allowing for lubrication, manufacturing errors, deflection under load, and thermal expansion.
