Specific implementation mode
The utility model is described in detail below in conjunction with attached drawing.
As shown in Figs. 1-3, the present embodiment provides a kind of reinforced Hollow Roller tapered roller thrust bearings, including seat ring
100, blowout patche 200, roller 500, retainer, positioning inner ring 300, positioning outer ring 400 and locating rod 600, wherein roller 500 have
There is the location hole 510 through both ends of the surface, positioning inner ring 300 and positioning outer ring 400 are cyclic structure, and the one of positioning outer ring 400
End face abuts to 100 medial surface of seat ring, and positioning inner ring 300 is mounted between the inner side end of roller 500, and positions inner ring 300
Outer ring surface it is opposite with the inner face of roller 500, positioning outer ring 400 is sleeved on the outside of roller 500, and positions the interior of outer ring 400
Anchor ring is opposite with the outer end face of roller 500, and positioning outer ring 400 has the screw hole opposite with 510 position of location hole, positions inner ring
300 have the unthreaded hole 321 opposite with 510 position of location hole, and 600 main body of locating rod, which is smooth and latter end, has screw thread, positioning
Bar 600 is inserted successively in unthreaded hole 321 and location hole 510, and the threaded portion of 600 end of locating rod is threadedly coupled fixation with screw hole.
Specifically, as shown in Figure 1, seat ring 100, blowout patche 200 and retainer in originally implementing similarly to the prior art, it is poor
