Design and characteristics of a new magnetic worm gear using permanent magnet

摘要

The structure and the method of design of a magnetic worm gear using a permanent magnet are described. The basic concept of the design is as follows: high gear ratio; and meshing based on internal contact to enlarge the meshing area and reduce the size of the gear. The trial magnetic worm gear has a gear ratio of 1:33. The measured maximum transmitted torque is 11.5 Nm.
