Worm gears are highly precise and powerful axle offset gears. They are low noise and insensitive to shocks. A worm gear consists of a worm shaft, which can be single or multi-start, and a worm wheel, which has vibration-damping properties. Due to the operating principle, a worm gear allows for high gear ratios in a single gear stage. There is a possibility of dynamic and static self-locking depending on the size and gear ratio of the gear.
