摘要:
A ceramic ball bearing assembly has raceway components generally held in residual compression by accompanying metal attachments. In a ceramic ball bearing assembly, an outer raceway is formed that is held in compression by a circumscribing steel ring. The components may be fitted together with the ceramic raceway subject to thermal contraction while the steel ring is subject to thermal expansion. Upon mating, the ceramic raceway slightly expands while the steel ring slightly contracts to impose residual compression upon the ceramic raceway. The residual compression preserves the ceramic raceway despite thermal or other stresses of operating environment. An inner ceramic raceway is constructed by employing one of several of the herein described methods, and the ceramic ball bearing assembly of the present invention may use balls, needles, cylinders, or other rolling elements in order to achieve smooth angular translation between the inner and outer ceramic raceways.
