An anti-rotational bearing assembly including a bearing positioned in a bearing bore of a bearing hub and a bearing cap connected to the bearing. The bearing cap including a projecting portion which abuts a boss extending from the bearing hub to prevent rotation of the bearing.
Claims30
A bearing anti-rotation apparatus adapted to operate with a bearing and a bearing bore, the apparatus comprising:
- a cover defining a hole, wherein the cover is adjacent the bearing;
- an edge depending from the cover and sized to fit around the bearing;
- a projection extending from the cover, whereby the projection prevents rotation of the bearing;
- and
- a boss extending upward from the bearing bore, wherein the bearing is positioned in the bearing bore.
2 more elements
An interface between a motor and a structure having a rotatable shaft, the interface comprising:
- a bracket connected to the motor and defining a bearing bore, wherein the bearing bore includes a bearing hub;
- a bearing positioned in the bearing bore;
- and
- a bearing cap connected to the bearing.
1 more element
An anti-rotational bearing assembly comprising:
- a bearing hub defining a bearing bore, the bearing hub having a surface surrounding the bore and a boss extending from the surface;
- a bearing seated in the bearing bore;
- and
- a bearing cap having a cover with a edge depending from the cover and sized to fit around the bearing such that the bearing cap is press fitted onto the bearing, the bearing cap further having a projection extending from the cover such that the projection prevents rotation of the bearing by contacting the boss.
1 more element
A method of preventing wallowing of a motor bore comprising the steps of
- preventing outer ball bearing race creepage;
- pressing a bearing cap onto a bearing, wherein the bearing cap includes a tang extending beyond an outer race of the bearing;
- pressing the bearing onto a shaft of the motor to form a shaft-bearing assembly;
- and
- inserting the shaft-bearing assembly into a bracket housing, wherein the bracket housing includes a boss positioned to interfere with rotation of the tang.
