Worm gearboxes and motors
Worm gears are helical gears and where the rotary motion of a worm gear on a cylindrical shaft is transmitted to a rotating gear wheel that is offset by 90°. These gears allow a particularly high gear ratios in a confined spaces and are therefore ideal for use in tight spaces.
The worm gear consists of two components: a threaded worm shaft and a threaded worm wheel. The worm shaft is usually made of steel and the worm wheel is usually made of bronze.
Worm gears are high-precision and very strong offset gears. They are mainly used when a large overall gear ratio is required. With a worm gear and worm wheel, a large overall ratio can be achieved with fewer steps. This means that a smaller, less expensive gearboxes can be used.
These high-performance gears meet our requirements every time and in every respect and are used in demanding applications such as conveyor systems, mills and bucket elevators, extrusion machines, machine tools or separating machines.
