Utility model content
The purpose of this utility model is to provide a kind of high axial carrying plain thrust bearings, to solve above-mentioned background technique The problem of middle proposition.
To achieve the above object, the utility model provides the following technical solutions: a kind of high axial carrying plain thrust bearing, Including outer ring, the bottom of the outer ring is provided with secondary outer by attachment screw, and the outer ring is internally provided with inner ring, institute The bearing race one that inner ring and outer ring mating surface is provided with annular is stated, big spin is provided in the bearing race one, it is described interior The outer wall of circle and the top mating surface of secondary outer are provided with the bearing race two of annular, are provided in the bearing race two small Spin, the outer wall of the inner ring and the inner wall mating surface of secondary outer are provided with the bearing race three of annular, the bearing race The staggeredly end face that middle spin, the inner ring and outer ring and secondary outer are provided in three is provided with band, the inner ring Top is provided with oil inlet, and the bottom of the oil inlet extends to inside bearing race one, and the oil inlet is provided with plug cock bar.
Preferably, the top band is mounted on the inner wall of outer ring by slot, and band described in bottom is installed by slot In the outer wall of inner ring.
Preferably, the oil inlet and plug cock bar are by being threadedly engaged assembly.
Preferably, the attachment screw connects secondary outer and outer ring by stepped hole.
Preferably, the attachment screw is six composition annular spreads.
Compared with prior art, the utility model has the beneficial effects that rotation axis is pierced into inner ring from bottom when work Inner hole, drives inner ring rotation when rotation axis rotates, inner ring by big spin, small spin and middle ball turns outer ring rotating relatively, Inner ring is longitudinally squeezed by big spin and small spin and outer ring simultaneously, bears high axial force, the axial direction for improving pivoting support is held Loading capability substantially increases the service life of pivoting support.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model.
In figure: 1 outer ring, 2 secondary outers, 3 attachment screws, 4 inner rings, 5 big spin, 51 bearing races one, 6 small spin, 61 Spin, 71 bearing races three, 8 bands, 9 oil inlets, 10 plug cock bars in bearing race two, 7.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.
Referring to Fig. 1, the utility model provides a kind of technical solution: a kind of high axial carrying plain thrust bearing, including The bottom of outer ring 1, outer ring 1 is provided with secondary outer 2 by attachment screw 3, and outer ring 1 is internally provided with inner ring 4,4 He of inner ring 1 mating surface of outer ring is provided with the bearing race 1 of annular, is provided with big spin 5, the outer wall of inner ring 4 in bearing race 1 It is provided with the bearing race 2 61 of annular with the top mating surface of secondary outer 2, is provided with small spin 6 in bearing race 2 61, The outer wall of inner ring 4 and the inner wall mating surface of secondary outer 2 are provided with the bearing race 3 71 of annular, set in bearing race 3 71 The staggeredly end face for being equipped with middle spin 7, inner ring 4 and outer ring 1 and secondary outer 2 is provided with band 8, the top setting of inner ring 4 There is oil inlet 9, the bottom of oil inlet 9 extends to inside bearing race 1, and oil inlet 9 is provided with plug cock bar 10.
Wherein, top band 8 is mounted on the inner wall of outer ring 1 by slot, and sealed bottom band 8 is mounted on inner ring 4 by slot Outer wall, prevent dust from entering the movement for influencing big spin 5, small spin 6 and middle spin 7, avoid the loss of lubricating oil.
Oil inlet 9 and plug cock bar 10 prevent plug cock bar 10 from falling off by being threadedly engaged assembly, good airproof performance.
Attachment screw 3 connects secondary outer 2 and outer ring 1 by stepped hole, and secondary outer 2 and outer ring 1 are connected as one, Prevent 4 loose or dislocation of inner ring.
