Abstract
The invention discloses a retainer for a tapered roller bearing and a bearing with the retainer. The retainer for the tapered roller bearing comprises a retainer body, the retainer body comprises a large end ring and a small end ring which are parallelly arranged in the axial direction, transverse ribs which are circumferentially distributed are connected between the large end ring and the small end ring, the two adjacent transverse ribs, the large end ring and the small end ring define a tapered pocket which is used for placing the tapered rollers, the walls at the large end and the small end of the tapered pocket are provided with parallel slopes, the outer sides of the slopes are close to the small end, the inner sides of the slopes are close to the large end, stopping surfaces which are used for preventing the tapered rollers from coming off are arranged on the opposite surfaces of the two adjacent transverse ribs, and the outer circumferential surface of the large end ring is a cylindrical surface with the axis of the bearing retainer as a centre line. According to the retainer for the tapered roller bearing and the bearing with the retainer, the outer circumferential surface of the large end ring is designed to be the cylindrical surface so that the gap between the outer diameter of the retainer and an inner roller way of an outer ring is enlarged, the bearing is effectively prevented from contacting with the inner roller way of the outer ring, the rotating flexibility of the bearing is improved, and the service life of the bearing is prolonged.
