Claims15
An assembly, comprising:
- a housing having a bearing seat and a snap ring groove;
- a rolling bearing located on the bearing seat adjacent to the snap ring groove;
- a snap ring located in the snap ring groove, the snap ring extending radially along a portion of the rolling bearing;
- and
- a press-fit retainer engaged to the housing with a press-fit on an axially opposite side of the snap ring from the rolling bearing, wherein the press-fit retainer has a coefficient of thermal expansion that is equal to or greater than a coefficient of thermal expansion of the rolling bearing and the housing.
A method of assembling an eAxle, the method comprising:
- providing a housing having a bearing seat and a snap ring groove;
- installing a rolling bearing on the bearing seat adjacent to the snap ring groove;
- installing a snap ring in the snap ring groove, the snap ring extending radially along a portion of the rolling bearing;
- and
- press-fitting a press-fit retainer into the housing with a press-fit on an axially opposite side of the snap ring from the rolling bearing, wherein the press-fit retainer has a coefficient of thermal expansion that is equal to or greater than a coefficient of thermal expansion of the rolling bearing and the housing.
