Abstract
A kind of self-aligning thrust roller bearing, including seat ring, blowout patche and retainer component.Seat ring is equipped with retainer component, and retainer component includes first, second washer of retainer and pillar, is fixed with multiple pillars between two retainer washers, a symmetrical hollow spherical roller is arranged on each pillar.Blowout patche is equipped with above retainer component.Blowout patche eliminates the rib structure of guiding rolling element basal plane, and discontinuity equalization is avoided to cause rib premature failure, can reduce bearing friction power, reduces stress concentration.Rolling element is symmetrical symmetrical hollow spherical roller, enhances the bearing capacity of bearing.Retainer component ensure that the function of retainer and the black box of symmetrical hollow spherical roller, realize the smart scroll of rolling element, improve bearing rotary flexibility.
Description
Technical field：
The utility model belongs to field of bearings, more particularly to a kind of self-aligning thrust roller bearing, can be useful in suspension hook neck
Domain, since this class bearing is usually large size bearing, this bearing bore diameter is up to 400-1000mm.
Background technology
The composition of traditional self-aligning thrust roller bearing, seat rings of the 12- without rib.13- has the blowout patche of rib, blowout patche rib
It is guided with roller major part basal plane.The asymmetric spherical roller of 9- major parts dribbling basal plane.11- vehicle solid cages.10- is served as a contrast
Set.When bearing is in low speed, heavily loaded environment, when bearing the radial impact force of very little, the easily improper failure of rib of blowout patche is damaged
It is bad, for this present situation, the structure of traditional self-aligning thrust roller bearing is improved in low-speed heave-load environment, is to meet market need
The active demand asked.
Utility model content
The purpose of this utility model is to provide a kind of self-aligning thrust roller bearing, improves structure, large carrying capacity service life
It is longer,.
The technical solution adopted is that：
A kind of self-aligning thrust roller bearing, including seat ring, blowout patche and retainer component.
Technical points are：
Seat ring is equipped with retainer component, and retainer component includes the first washer of retainer, retainer second packing ring and branch
Column is fixed with multiple pillars between the first washer of retainer and retainer second packing ring, one is arranged on each pillar symmetrically
Hollow spherical roller.
Blowout patche is equipped with above retainer component.
The first washer of retainer is located on the outside of retainer second packing ring.
It the advantage is that：
Blowout patche eliminates the rib structure of guiding rolling element basal plane, and discontinuity equalization is avoided to cause rib premature failure, is changed
Become the internal structure design of bearing, changed the force structure of Bearing inner, bearing friction power can be reduced, reduce stress collection
In.
Rolling element is symmetrical symmetrical hollow spherical roller, the asymmetric spherical roller for basal plane of dribbling compared with major part,
Process complexity and difficulty of processing are reduced, optimizes it and rolls the adaptation of busbar and seat ring raceway, enhance the carrying energy of bearing
Power.
The first washer of retainer, retainer second packing ring and multiple pillars ensure that retainer is rolled with symmetrical hollow spheric
The function of the black box of son realizes the smart scroll of rolling element, improves bearing rotary flexibility.

Specific embodiment
A kind of self-aligning thrust roller bearing, including seat ring 1, blowout patche 2 and retainer component.
Seat ring 1 is equipped with retainer component, and retainer component includes the first washer of retainer 4,5 and of retainer second packing ring
Pillar 6 is fixed with multiple pillars 6, one is arranged on each pillar 6 between the first washer of retainer 4 and retainer second packing ring 5
A symmetrical hollow spherical roller 3.
Blowout patche 2 is equipped with above retainer component.
The first washer of retainer 4 is located at 5 outside of retainer second packing ring.
Seat ring 1 is traditional seat ring, and for blowout patche 2 without rib structure, symmetrical hollow spherical roller 3 is symmetrical along A-A faces
Symmetrical hollow spherical roller.
Since bearings is usually large-scale, so offering blowout patche hole for hoist 7 on blowout patche 2, opened up on seat ring 1
There is seat ring hole for hoist 8, realize convenience when carrying and installation, fast.
The position and bearing axis of symmetrical 3 load of hollow spherical roller are obliquely installed to form contact angle, can bear compared with
The axial load of weight, can also bear radial load, have automatic aligning performance.The cancellation of 2 rib of blowout patche, avoids and works as bearing
When bearing radial impact load, rib premature failure, using symmetrical hollow spherical roller 3, post cage ensure that retainer
With the function of the black box of symmetrical hollow spherical roller 3.Due to the change of inner structure form, bearing capacity is improved, is realized
Specified dynamic load increases 10-15%, and specified footpath, which carries, increases 15-20%, effectively extends the service life of bearing.
Seat ring 1, blowout patche 2 and retainer component can be assembled into bearing at the scene, easy for installation.
1 raceway face of seat ring is ball-track, and the symmetrical hollow spherical roller 3 of rolling element rolls shape of generatrix and rolled with seat ring 1
Road is engaged, and has the function of to compensate shaft distortion error automatically.
