Abstract

Instrument ball bearings are used in pairs, loaded against each other, mounted on a shaft, and contained in a housing. Their most important function is to define a spin axis. We develop a vector manufacturing error characterization for each bearing component. We calculate the combined misalignment of a loaded bearing pair, coupled by shaft/housing elasticity, to give a time-dependent resultant displacement/direction of the spin axis with respect to a spin reference axis. Effects of initial placement, contact angle mismatch, and total rotation angle are considered. We suggest that selective assembly with error cancellation is possible for some applications.
