Abstract
The invention discloses a tapered roller bearing and a retainer for the same. The retainer for the tapered roller bearing comprises a retainer body, the retainer body comprises a large ring and a small ring which are parallelly arranged in the axial direction, end surfaces of the large ring and the small ring are perpendicular to the axes of the large ring and the small ring, transverse ribs are connected between the large ring and the small ring, the two adjacent transverse ribs, the large ring and the small ring define a tapered pocket, the walls at the large end and the small end of the tapered pocket are provided with parallel slopes, and stopping cambered surfaces which are used for preventing tapered rollers from coming off are arranged on the opposite surfaces of the two adjacent transverse ribs. The middles of the outer side surfaces of the transverse ribs are tangent to the outer circumference of the small ring in an inclined mode to form outer inclined surfaces, the middles of the inner side surfaces of the transverse ribs are tangent to the inner side surface of the large ring in an inclined mode to form inner inclined surfaces, the inner inclined surfaces and the outer inclined surfaces are intersected with the stopping cambered surfaces on the transverse ribs to form inner arc edges and outer arc edges, the corresponding inner arc edges of the two adjacent transverse ribs form an inner opening for the tapered rollers to penetrate through, and the corresponding outer arc edges of the two adjacent transverse ribs form an outer opening for the tapered rollers to penetrate out of. According to the tapered roller bearing and the retainer for the same, the middle portions of the cambered surfaces form channels for small ends of the tapered rollers to penetrate through, and the installation is facilitated.
