Filed:

May 10, 1984

Appl. No.:

6/623450

Inventors:

David G. Falconer - Arlington VA

International Classification:

F16C 3202

US Classification:

308 2A

Abstract:

A pivot bearing comprises an outer ring-like structure and an inner concentric central structure. Each structure holds cams usually having one type of contour, an involute contour on the outer structure and a cylindrical contour on the inner structure e. g. Flexible pendulums cut to length are affixed at one end to each individual cam of the outer involute cams and at their opposite ends to each individual cylindrical cam. The intermediate area of the pendulums between the fixed positions of flexible pendulums tautly and contiguously envelop the cam contours. The center structure, which may serve as a shaft, is held concentric and free to pivot from one ambit to the other ambit in apposition to each position.

Abstract:

A combination linear bearing and force-generating mechanism comprising an outer frame attached to a first set of cams and an inner shaft attached to a second set of cams. Flexible pendulums connect and wrap around the first and second set of cams, the flexible pendulum being formed and constrained thereby to produce non-arcuate, linear mobility to the inner shaft.
