Worm Gearboxes Line X, K, H, XX, KX and KK

Gear or a Speed Regulating Gearbox is a mechanical device that reduces the speed (rotation) of a drive unit (electric motor), converting this reduction into an increase in available torque.

A mechanical speed governor is a device that is normally coupled to an electric motor or other drive unit, with which rotations can be varied through a laterally installed “wheel”.
