Rotor structure for gyroscopic apparatus

摘要

A gyroscopic rotor device is designed to eliminate any spin bearing outer raceway distortion and/or axial preload changes due to centrifugal and thermal effects in a bimetal rotor assembly by means of judicial geometric shaping of the rotor components. The shaping of the heavy metal motor rim and/or the lower density metal rotor spin bearing support web interface includes a discrete number of stress concentrating pads and an equal number of holes formed in the bearing web opposite each of the pads for isolating any strain induced within the bearing web from the spin bearing outer race.
