ABSTRACT:
A bearing construction interposes the coils of one or more coil springs between bearing surfaces. In one embodiment a bearing coil spring is wrapped around a shaft several times. The bearing coil spring may be freely mounted on a more substantial race coil retainer centered on the shaft. In another embodiment toroidal coil springs separated by disc races extend circularly about the shaft. In linear bearing construction, the bearing coils are in planes parallel to the line of shaft movement. Other embodiments of the invention involve disengageable shafts having complementary centering end-faces accommodating misalignment through the yield able action of the bearing spring coils, shafts and housings having non-circular cross-sections, and shafts and housings not having completely complementary surfaces to enable interference fit and positional control.
