Basic Guide to Gearbox.

  What is a Gearbox? A gearbox is a mechanical device that is used to increase the output torque of the motor or change its speed (RPM). The motor shaft is attached to one end of the gearbox and provides a given output torque and speed determined by the gear ratio through the internal gear configuration of the gearbox. Physical properties The physical components of gearboxes differ for different types of gearboxes and for different manufacturers. Most gearboxes are made of steel materials such as iron, aluminum, and brass. Unlike other types of gearboxes, spur gearboxes can also be made of plastic like polycarbonate or nylon. In addition to the raw materials used, the orientation of the gear teeth plays an important role in the overall efficiency, torque, and speed of the system. Spur gear gearboxes are generally used for low speed applications. These gearboxes can be noisy and overall efficiency can be low. Helical gearboxes are generally used for high speed applications.
