Gear Manufacturers

Gear manufacturers produce devices, which are used in conjunction with other gears and parts, that engage mechanical motion and/or transfer rotational torque power and motion through a shaft, other gears or series of parts. The make custom gear assemblies for nearly any commercial or industrial application within the food processing, textile manufacturing, clock making, heavy industrial mining equipment and oil rigging equipment industries. Bevel gears, sprockets, rack and pinion spur gears, planetary gears and helical gears are crucial in automotive motors and power transmissions, while small plastic gears and nylon gears are used in consumer products. Different sized gears are used with one another to increase or reduce a shaft's rotational speed in speed reducers, motors, transmissions, heavy machinery and clocks.

Gear manufacturers use gear cutting techniques such as gear hobbing to fabricate gears, designing their products to withstand harsh and repetitive use. A gear's number of teeth and its specific gear ratio determine the function, speed and control the gear will have within a larger gear assembly. These factors will determine the gear's durability and strength, and also the speed it will be able to engage. Gears may be made from a variety of materials, including most metals and hard plastics. Highly wear resistant plastics such as nylon and polycarbonate are useful in machinery applications where low weight is a requirement; in demanding applications such as automotive transmissions, gears are made from hard metals such as steel, brass, copper and even titanium. Noise, heat, vibration and presence of corrosive elements are all possible impediments to gear performance, which is why most gear systems use a form of lubrication.
