Abstract
Friction in a traction drive assembly having counter-rotating races interconnected by drive balls captured by a stationary retainer is substantially reduced, and the life of the assembly is substantially extended, by interposing rolling interface elements between the drive balls and the retainer. The interface elements may take the form of balls, pins or wheels, and separate lubricating means for them may be provided.
