Abstract
A bearing outer face construction system includes a bearing having a bearing outer race. The bearing outer race includes an outer race surface. At least one circumferential groove is recessed into the bearing outer race. An expanding member is received in the at least one circumferential groove. A housing receives the bearing having a gap between a housing inner face and the bearing outer race. The expanding member expands to radially extend across the gap into direct contact with the housing inner face to mitigate against motion between the bearing and the housing inner face.
Claims20
A vehicle bearing outer face construction system, comprising:
- a bearing having a bearing outer race, the bearing outer race including an outer race surface;
- at least one circumferential groove recessed into the bearing outer race;
- an expanding member received in the at least one circumferential groove;
- and
- a housing receiving the bearing having a gap between a housing inner face and the bearing outer race, the expanding member expanding to radially extend across the gap into direct contact with the housing inner face to mitigate against motion between the bearing and the housing inner face.
A bearing outer face construction system, comprising:
- a bearing having a bearing outer race;
- at least one circumferential groove recessed into the bearing outer race;
- an expanding member of an elastomeric rubber and having an impedance received in the at least one circumferential groove;
- and
- a housing having a housing inner face, the housing receiving the bearing having a gap remaining between the housing inner face and the bearing outer race, the expanding member expanding to radially extend across the gap into direct contact with the housing inner face to mitigate against motion between the bearing and the housing inner face, and wherein the impedance mitigates against an electrical current passing between the bearing and the housing.
A method to construct a bearing outer face, comprising:
- creating a bearing having a bearing outer race including an outer race surface;
- recessing at least one circumferential groove into the bearing outer race;
- positioning an expanding member in the at least one circumferential groove;
- installing the bearing into a housing having a gap between a housing inner face and the bearing outer race;
- and
- inducing expansion of the expanding member to radially extend across the gap into direct contact with the housing inner face to mitigate against motion between the bearing and the housing inner face.
