Description
Technical field
The utility model is related to technical field of bearings, concretely relate to a kind of cylindrical roller thrust bearing.
Background technology
The equal length of roller in each pocket hole of existing cylindrical roller thrust bearing, and the end face of rolling element is flat
's.Such structure allows the rolling element in work to have different linear velocities, generates distortion power and sliding friction, reduces bearing
Service life.
Utility model content
The utility model the technical problem to be solved is that in place of overcome the deficiencies in the prior art, provide a kind of to use the longevity
Order long cylindrical roller thrust bearing.
To achieve the above object, the utility model provides the following technical solutions：A kind of cylindrical roller thrust bearing, including axis
Circle, seat ring and retainer, the retainer are mounted between blowout patche and seat ring, are filled respectively in each pocket hole of the retainer
There are the roller I and roller II of different length and laid out in parallel, an end face of the roller I is concave ball surfaces I, another end face
An end face for convex spherical I, the roller II is concave ball surfaces II, another end face is convex spherical II, the spill
Spherical surface I cooperates with convex spherical II, and convex spherical I and concave ball surfaces II cooperate.
Further, the retainer is structure as a whole.
Further, the roller I and roller II are cylindrical structure.
Further, hole for hoist I, hole for hoist II and hole for hoist III are respectively equipped on the blowout patche, seat ring and retainer.
Further, the roller I in the two neighboring pocket hole of the retainer is opposite with the arrangement position of roller II.
Compared with prior art, advantageous effect is the utility model：
(1) two end faces of roller I and roller II are separately designed to be convex spherical structure on one side, another side is spill
Spherical structure makes roller I and roller II at work, and the end face of two rollers can form one layer of lubricating oil film, and reduction connects
The rate of touching, makes the service life of roller increase.
(2) roller I and roller II of two different lengths are respectively provided in each pocket hole, and in two neighboring pocket hole
Roller I and roller II arrange position on the contrary, make roller I and roller II at work, be respectively provided with different linear velocities, avoid rolling
Son bears distortion power and sliding friction, to greatly improve bearing life.

Specific implementation mode
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
The every other embodiment obtained, shall fall within the protection scope of the present invention.
As shown in Figure 1-Figure 3, a kind of cylindrical roller thrust bearing, including blowout patche 1, seat ring 2 and retainer 3, the holding
Frame 3 is mounted between blowout patche 1 and seat ring 2, and different length and laid out in parallel are respectively provided in each pocket hole of the retainer 3
Roller I 4 and roller II 5, an end face of the roller I 4 be I 4-1 of concave ball surfaces, another end face is I 4- of convex spherical
2, an end face of the roller II 5 is II 5-1 of concave ball surfaces, another end face is II 5-2 of convex spherical, the concave ball surfaces
I 4-1 cooperates with II 5-2 of convex spherical, and I 4-2 of convex spherical and II 5-1 of concave ball surfaces cooperate.
The retainer 3 is structure as a whole.
The roller I 4 and roller II 5 are cylindrical structure.
For the ease of carrying and installation, hole for hoist I 6, hole for hoist are respectively equipped on the blowout patche 1, seat ring 2 and retainer 3
II 7 and hole for hoist III 8.
In use, retainer 3 is circumferentially equipped with multiple pocket holes, by II 5 (this implementation of the roller I 4 of different length and roller
Example is that the length of roller I 4 is more than the length of roller II 5) laid out in parallel is placed in each pocket hole of retainer 3, two neighboring pocket
The arrangement position of roller I 4 and roller II 5 in hole is opposite (with reference to Fig. 4), the concave ball surfaces of convex spherical I 4-2 and roller II 5
II 5-1 cooperates, and has lubricating oil in pocket hole, and when work, the end face of two rollers can form one layer of lubricating oil film, drop
Low contact rate makes rolling element at work, is respectively provided with different linear velocities, rolling element is avoided to bear distortion power and sliding friction,
To greatly improve bearing life, bearing service life improves about 15%-20%.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is appreciated that can these embodiments be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaiied
Change, replace and modification, the scope of the utility model are defined by the appended claims and the equivalents thereof.
