Retainer for window type tapered roller bearing and tapered roller bearing

Abstract

The utility model relates to a bearing, in particular to a retainer for a window type tapered roller bearing and the tapered roller bearing. The retainer for the window type tapered roller bearing comprises a retainer body, a plurality of pockets are formed in the retainer body in an annular array mode, and a plurality of anti-attrition grooves are formed in the two side faces, opposite to the conical face of a tapered roller, of each pocket. According to the retainer for the window type tapered roller bearing provided by the utility model, the contact area between the retainer and a rolling body is reduced by arranging the anti-attrition grooves on the two sides of the pocket holes, so that the abrasion of the pocket holes is reduced, the radial and axial movement amount of the retainer relative to the rolling body is prevented from being increased, the stable operation is ensured, and the service life of the retainer is prolonged. And the service life of the retainer is prolonged.

Description

TECHNICAL FIELD

[0001] The utility model relates to a bearing, especially a cage for window type tapered roller bearing and a tapered roller bearing. BACKGROUND

[0002] The existing window type stamping cage tapered roller bearing is abraded in the objective existing cage pocket after a certain period of use, which leads to the increase of the radial and axial movement of the cage relative to the rolling body, the increase of the runout of the cage during operation, the increase of the shear force, the deformation and fracture of the cage, and the abnormal failure of bearing burning. SUMMARY

[0003] To solve the problem of easy abrasion of the pocket, the utility model provides a cage for window type tapered roller bearing, and the specific technical scheme is as follows:

[0004] A cage for window type tapered roller bearing, comprising a cage body, a plurality of pockets are arranged in an annular array on the cage body, and a plurality of wear reduction grooves are arranged on the two sides of the pocket opposite to the conical surface of the tapered roller.

[0005] A tapered roller bearing, comprising the cage for window type tapered roller bearing.

[0006] Compared with the prior art, the utility model has the following beneficial effects:

[0007] The cage for window type tapered roller bearing provided by the utility model reduces the contact area with the rolling body by arranging wear reduction grooves on the two sides of the pocket, thereby reducing the abrasion of the pocket, avoiding the increase of the radial and axial movement of the cage relative to the rolling body, and ensuring stable operation and prolonging the service life of the cage. BRIEF DESCRIPTION OF DRAWINGS

[0008] Figure 1 is the structural schematic view of the utility model;

[0009] Figure 2 is the structural schematic view of the pocket. DETAILED DESCRIPTION

[0010] The utility model will be further described in combination with the drawings.

[0011] Embodiment one

[0012] As Figure 1 and Figure 2As shown in the accompanying drawings, a cage for window type tapered roller bearing comprises a cage body 4, and a plurality of pockets 41 are arranged in an annular array on the cage body 4, and each of the pockets 41 is provided with a plurality of anti-friction grooves 42 on both sides opposite to the tapered surface of the tapered roller 3.

[0013] The anti-friction grooves 42 effectively reduce the wear problem of the pockets 41 of the cage, solve the problems of deformation and fracture of the cage, abnormal failure such as bearing burning, and make the bearing run more smoothly, thereby prolonging the service life of the bearing.

[0014] Embodiment Two

[0015] As shown in the accompanying drawings, Figure 1 and Figure 2 A tapered roller bearing comprises a cage for window type tapered roller bearing. Specifically, the tapered roller bearing comprises an inner ring 1, a tapered roller 3, an outer ring 2, a spacer 5 and a cage body 4, the inner ring 1, the outer ring 2, the spacer 5 and the cage body 4 are coaxially arranged, the tapered roller 3 is located between the inner ring 1 and the outer ring 2 and movably located in the pocket 41 of the cage body 4, and the spacer 5 is located between the two outer rings 2.

[0016] The technical principles of the present application are described above in combination with specific embodiments. These descriptions are only for explaining the principles of the present application, and cannot be interpreted as limiting the protection scope of the present application in any way. Based on the above explanations, other specific embodiments of the present application can be conceived by those skilled in the art without creative labor, and these embodiments will fall within the protection scope of the claims of the present application.
