Abstract
A bearing includes an inner race member having an end surface. An outer race member is disposed about the inner race member. The outer race member has an internal shoulder for engaging the end surface of the inner race member. The inner and outer race members are configured to define a raceway between them and to define a snap ring seat between them. There are cylindrical rollers in the raceway and a snap ring in the snap ring seat. The bearing may be provided as a follower head on a cam follower or may be eccentrically mounted on a drive shaft to serve as a cam. A bearing can be assembled by inserting the inner race member into the outer race member, disposing cylindrical rollers in the raceway and disposing a snap ring in the snap ring seat.
Claims11
A bearing comprising:
- an inner race member having a raceway surface, a first end surface, and a second end surface;
- and
- an outer race member disposed about the inner race member, the outer race member having an internal shoulder for engaging the first end surface of the inner race member;
- the inner race member and the outer race member being configured to define a raceway between them;
- a plurality of rolling elements disposed in the raceway;
- the inner race member defining an inner race snap ring groove in the raceway surface;
- the outer race member defining an outer race snap ring groove;
- wherein the inner race snap ring groove substantially aligns with the outer race snap ring groove to define a seat for a snap ring when the internal shoulder engages the first end surface.
A method of assembling a bearing, comprising:
- providing a inner race member having a raceway surface, a first end surface and a second end surface, the inner race member defining an inner race snap ring groove;
- providing an outer race member having an internal shoulder for engaging the first end surface of the inner race member and defining an outer race snap ring groove,
- wherein the inner race member and the outer race member are configured to define a raceway between them,
- disposing a plurality of rolling elements in the raceway;
- wherein when the first end surface engages the internal shoulder the inner race snap ring groove aligns with the outer race snap ring groove to provide a seat for a snap ring.
A bearing comprising:
- an inner race member having a raceway surface, a first end surface, and a second end surface;
- an outer race member disposed about the inner race member, the outer race member having an internal shoulder for engaging the first end surface of the inner race member;
- the inner race member and the outer race member being configured to define a raceway between them;
- a plurality of rolling elements disposed in the raceway;
- the inner race member defining a shoulder in its raceway surface;
- the outer race member defining a groove;
- wherein the groove is aligned with the shoulder in the inner race member when the inner race member is fully inserted into the outer race member;
- a snap ring disposed in the groove;
- wherein the snap ring serves to inhibit the removal of the inner race member from the outer race member by bearing against the shoulder in the raceway surface.
