A linear motion ball bearing assembly is provided for mounting within a housing and comprises a plurality of ball retainer members with a raceway therein. With the members surrounding a shaft, a load bearing plate is associated with the load bearing portion of each raceway and on the outer periphery of each raceway an elastomeric strip of material is mounted to resiliently restrain the movement of the ball bearing assembly in the spherical seat within the housing, and provide a high damping factor and exhibit high static stiffness.

Linear motion ball bearing with dynamic stiffness

This invention relates to a clutch tooth design which provides increased load carrying ability by having substantial face to face contact of the teeth during a partial engagement of the clutch teeth. The teeth of the clutch are machined to a profile form which is of exponential shape. Mating contact areas lie in a mid-pitch plane perpendicular to the axis of rotation of the clutch. The mutual tangent between two contacting teeth lies in a truly helicoid surface. The essential line contacts resulting from machining are converted by a coining process to areas large enough to carry the service loads. As a result the tooth form developed actually improves with continued use.
