ABSTRACT:
A speed reducer (or increaser) has a group of planetary members with a major diameter bearing on a central annular member in rolling contact. The minor diameters of these members bear preferably on the inside surfaces of axially-spaced ring sections in rolling engagement on flared surfaces provided on either the ring sections of the planetary members, or both. The rolling engagement is under pressure generated preferably by urging one ring member axially in a direction to grip the planetary members between the ring sections and the central annular member as a result of change of the rolling position on the flared surfaces. An intermediate member is associated with the axis of the planetary members to provide peripheral spacing of the planetary members, and control of their position.
