Embodiment Construction
[0040]As shown in Figure 1, the structure of the tapered roller thrust bearing is that the rolling elements - tapered rollers 2 are arranged between the shaft ring 1 and the seat ring 3, and the tapered rollers are arranged equidistantly by the cage (not shown in the figure). show). The design and manufacture of the shaft ring, seat ring and tapered roller, that is, the raceway and rib, are exactly the same for the shaft ring and seat ring.
[0041] As shown in Figure 2, an oil film lubrication method for the large end surface of the thrust bearing tapered roller and the rib of the seat ring. ), a wedge-shaped gap with a large front and a small rear is formed between the front part of the large end face of the tapered roll and the inner wall of the seat ring rib, as indicated by "a" in the figure (that is, a convergent gap with a dynamic pressure effect. Wedge-shaped gap), like a water ski with a tilted front end, as long as it moves forward, it will generate buoyancy. The "...
