Helical worm gear units

These gear units combine the advantages of worm gear units with those of spur gear units:
In the high-speed range of the first gear stage, under lubrication-favourable conditions, the multi-speed worm shaft operates with an efficiency of up to 95%.
This is where the worm gear stage demonstrates its excellent vibration damping properties for optimised smooth running. Precise spur gear sets run in the second or third gear stage downstream with likewise excellent efficiency at low speed.
