The planar ball reducer is small in size and is simple in processing. However, the relative
velocity between the wave generator and ball is large, which decreases the operation …

This paper presents a method for designing a novel type of movable tooth drive
characterized by logarithmic spiral conjugated tooth profiles, which are in almost full surface …

This paper focuses on a novel harmonic movable tooth drive as an alternative of currently
used harmonic gear drives. Different from the harmonic gear drives, the novel drive removes …

A novel planar ball reducer (NPBR) is invented in which the relative velocity of meshing
surfaces is reduced to achieve high mechanical efficiency. In order to acquire an accurate …

In order to meet the need of compact structure for driving system with large transmission
ratio and high drive efficiency, a novel permanent magnet movable teeth motor is proposed …
