Kind Code:
A1
Abstract:
A cage and a bearing. The cage (2) comprises a first ring (5), a second ring (6), and a plurality of beams (7), which connect the first ring (5) to the second ring (6), wherein the plurality of beams (7) are spaced apart from each other in a circumferential direction of the cage (2), and a pocket (10) for accommodating a rolling element of a bearing is defined between adjacent beams (7). A side surface of each beam (7) in the circumferential direction comprises a first pressed slope (13) and a second pressed slope (15), which are spaced apart from each other, and a recess (12), which is kept in at least one end of the pocket (10) of the cage (2) and extends from the first pressed slope (13) to a longitudinal center line (S) of the beam and to a longitudinal end portion of the beam (7). The cage can facilitate the installation of a bearing, avoid the use of large apparatuses during assembly, and reduce damage to components of the bearing during assembly.
