Abstract
The radial roller bearing has an outer ring (1), an inner ring (2), several roller members (3), and a cage (4). The cage (4) is guided on the edges (1a) of the outer ring (1) via several supporting rollers (5) distributed around the circumference in the form, for example, of ball bearings. This makes it possible to avoid sliding friction for guiding the cage (4) and to guide the cage without any clearance, so that the roller bearing can attain a high limit speed.
Claims24
A radial antifriction bearing, comprising:
- an outer member having an inner surface;
- an inner member having an outer surface;
- a cage having a plurality of circumferentially spaced ridges separating a plurality of rolling elements from one another, said rolling elements being mounted within the cage and disposed between the inner member and the outer member, the rolling elements contacting and rolling on the inner surface of the outer member and the outer surface of the inner member;
- and
- a plurality of supporting rollers and corresponding shafts, each supporting roller being rotatably supported by the respective shaft, said supporting rollers and shafts being disposed about the circumference of the cage for guiding said cage by rolling contact;
- the supporting rollers having an outside diameter less than one-third the outside diameter of the cage.
The radial antifriction bearing for rotation about an outer surface of an inner member and an inner surface of an outer member, comprising:
- a cage having a plurality of circumferentially spaced ridges separating a plurality of rolling elements from one another, the rolling elements being mounted within the cage and disposed between the inner member and the outer member, the rolling elements contacting and rolling on the inner surface of the outer member and the outer surface of the inner member;
- a plurality of supporting rollers and corresponding shafts, each supporting roller rotatably supported by the respective shaft, said supporting rollers and shafts disposed about the circumference of the cage for guiding said cage by rolling contact;
- the supporting rollers having an outside diameter less than one-third the outside diameter of the cage.
