Abstract
A bearing assembly is described that includes a shaft and an inner race affixed to the shaft. An outer race is disposed radially around the inner race defining a bearing run space with rolling elements between the inner and outer races. An axial bore in the support or the rotor has a radial gap between the bore wall and the outer race, and the assembly is configured to provide a radial displacement between a portion of the outer race and the axial bore wall in response to a radial overload force applied to the rotor.
Claims13
A bearing assembly for providing engagement of a rotor and a support, comprising:
- a shaft;
- an inner race affixed to the shaft;
- an outer race disposed radially around the inner race, the inner and outer races together defining a bearing run space between the inner and outer races;
- and
- rolling elements in the bearing run space;
- wherein one of:
- (i) the shaft along with the inner race or (ii) the outer race, is attached to and configured to rotate with the rotor, and the other of (i) the shaft along with the inner race or (ii) the outer race, is attached to the support;
- a first axial bore that is in the rotor if the outer race is the rotor or is in the support if the outer race is attached to the support;
- a second axial bore that is in the support if the outer race is attached to the rotor or is in the rotor if the outer race is attached to the support;
- and
- wherein a first portion of the outer race is disposed in the first axial bore, and a second portion of the outer race is disposed in the second axial bore with a radial gap between a wall of the second axial bore and the second portion of the outer race;
- and
- further wherein the assembly is configured to provide a radial displacement between the second portion of the outer race and the second axial bore wall in response to a radial overload force applied to the rotor.
