Problems solved by technology
[0002] Thrust bearings are generally used to bear axial force. In some settings, thrust bearings are required not only to have good axial load capacity, but also to have a certain radial load capacity. However, the current thrust bearings are generally There is the problem of insufficient radial bearing capacity
In addition, ordinary tapered roller thrust bearings have the problem of large axial dimensions while increasing the radial load capacity, and their application will be limited, especially in the application of some large rotating structures

Embodiment 1
[0049] see Figure 1-Figure 3, Figure 7 with Figure 8 As shown, the plane tapered roller thrust bearing provided by the embodiment of the present invention includes a race 100 and a shaft ring 200. On the upper surface of the race 100, an inner retaining ring 101 and an outer retaining ring 101 are sequentially arranged at intervals from the center of the race 100 to the outer edge. A retaining ring 102, between the inner retaining ring 101 and the outer retaining ring 102, a plurality of stepped tapered rollers 103 are evenly distributed along the circumference, and each stepped tapered roller 103 has at least two stepped sections in its axial direction, for example, Two step sections and three step sections, the more step sections, the higher the corresponding processing difficulty. The upper surface of the seat ring 100 is a stepped tapered surface, and the lower surface of the shaft ring 200 is a stepped tapered surface.

The invention relates to the technical field of bearings, in particular to a plane tapered roller thrust bearing. The thrust bearing includes a seat ring and a shaft ring, and an inner retaining ring and an outer retaining ring are arranged between the seat ring and the shaft ring. The inner retaining ring and the outer retaining ring are arranged at intervals on the upper surface of the seat ring. There are stepped tapered rollers between the retaining rings. The upper surface of the seat ring and the lower surface of the shaft ring are stepped tapered surfaces that fit the tapered surfaces of the stepped tapered rollers. The stepped tapered rollers can be seated relative to each other around the axis of the seat ring. The thrust bearing can also rotate around its own axis. The stepped tapered rollers of the thrust bearing match the stepped tapered surfaces of the seat ring and the cover ring. In the radial direction of the bearing, the stepped tapered rollers and the lower surface of the shaft ring and the seat The stepped tapered surface between the upper surfaces of the rings forms a blocking structure, which greatly increases the radial bearing capacity of the bearing and reduces the axial dimension of the bearing as much as possible, and the stepped tapered rollers can revolve relative to the shaft ring and the seat ring, and can also revolve around themselves The axis rotates to reduce friction.

technical field [0001] The invention relates to the technical field of bearings, in particular to a plane tapered roller thrust bearing. Background technique [0002] Thrust bearings are generally used to bear axial force. In some settings, thrust bearings are required not only to have good axial load capacity, but also to have a certain radial load capacity. However, the current thrust bearings are generally There is the problem of insufficient radial bearing capacity. In addition, ordinary tapered roller thrust bearings have the problem of large axial dimension while increasing the radial load capacity, and their application will be limited, especially in the application of some large rotating structures. Contents of the invention [0003] The purpose of the present invention is to provide a flat tapered roller thrust bearing, which has better axial and radial bearing capacity, and at the same time reduces the axial dimension of the flat tapered roller thrust bearing as...
