It is complicated in high processing costs, axially to bearing capacity it is small the problem of.
Thrust bearing is the special bearing for specially bearing axial force, is just subject to the axle of the power in the direction parallel with axle
Hold, thrust bearing is merely able to bear axial load, and single thrust bearing is can only to bear the axial load in a direction, Bidirectional pulling
Power ball bearing can bear the axial load of both direction；Thrust bearing can not limit the radial displacement of axle, and limit speed is very low,
Single direction thrust ball bearing can limit the axial displacement in a direction of axle and housing, and two-way bearing can limit both direction
Axial displacement.
The content of the invention
The goal of the invention of the present invention is that there is provided the thrust that a kind of face is contacted in view of the above-mentioned problems, providing a kind of bearing assembly
Bearing, can meet low speed, heavy duty and the big operating mode of load change and use.
To reach above-mentioned purpose, the technical solution adopted in the present invention is：A kind of bearing assembly, including Shang Quan, lower circle and
Retainer between outer ring and inner ring, Shang Quan, lower circle size are corresponded to and presented down and be coaxially disposed；The upper circle lower surface edge
It is circumferentially with the sliding way of ring-type, and the Xia Quan upper surfaces are circumferentially with the glide path of ring-type along it, positioned at the sliding way
Slide mass is provided between glide path；The slide mass includes setting on multiple sliding shoes for convex structure, the sliding shoe
There are the top-surface camber portion of corresponding sliding way face laminating and the lower surface camber portion of correspondence glide path face laminating；The axially width in the top-surface camber portion
Degree is more than the axial width of glide path, the axial width of the axial width more than sliding way in lower surface camber portion；The week of the sliding shoe
It is coplanar to end face and the inner ring axis；The circumferential end faces of the sliding shoe form circular arc with curved face part thereon and lower surface camber portion
Transition；The placement position for the fit that correspondence sliding shoe is provided with the retainer, the retainer is set between the sliding shoe,
And be provided with lubricating chamber between the adjacent sliding shoe, lubricating chamber by dividing plate be divided into above and below two layers, separate and be provided with through hole；The profit
Sliding room be retainer, sliding way, glide path and sliding shoe end formed in cavity, the lubricating chamber retainer respectively with upper circle
At lateral edges, formed and be slidingly sealed at lower circle upper edge, retainer forms gluing, sealing with the axial both sides in sliding shoe end；Institute
State correspondence lubricating chamber on retainer and be provided with oil filler point.
It is preferred that, outer mounting groove is circumferentially with along the Shang Quan and lower circle radial outer end face, along the Shang Quan and lower circle
Radial inner end face be circumferentially with interior mounting groove, between the Shang Quan and lower circle be provided with dust ring；The dust ring includes outer anti-
Konisphere and inside and outside dust ring, outer dust ring upper and lower side are respectively equipped with the elastic flange of ring-type and radial inward, the elastic flange pair
It elastic should be caught in the interior mounting groove of Shang Quan and lower circle；Interior dust ring upper and lower side is respectively equipped with ring-type and radially elastic convex
Edge, elastic flange correspondence elasticity is caught in the interior mounting groove of Shang Quan and lower circle.
It is preferred that, the elastic flange is rubber structure；The outer mounting groove and interior mounting groove are that cross section band is non-blunt
The groove structure at angle turning.
It is preferred that, the sliding shoe is at least 4.
It is preferred that, the sliding way is identical with the radius of curvature of glide path.
It is preferred that, finishing bathtray is circumferentially with along sliding way on the upper circle, the finishing bathtray is located in the middle of sliding way；It is described
Lower oil groove is circumferentially with along glide path on lower circle, the outer oil sump is located in the middle of glide path.
Due to using above-mentioned technical proposal, the invention has the advantages that：
1. the present invention instead of rolling element of the prior art, it uses it by setting a slidable slide mass
Obtained bearing capacity is big, is adapted to low speed operation, can meet the big operating mode of bearing capacity change.Existing bearing roller is generally
Spherical or column, it is generally contact and a linear contact lay with the contact that Internal and external cycle is provided, although rolling effect is good, but in heavy type
Mechanical to wait other, it can not provide higher axial bearing capacity, the thrust bearing that the slide mass that the present invention is used is obtained, its roll body
The contact with Internal and external cycle is provided contacts for face, effectively increases axial bearing capacity；Rolling element is main with circle contact position up and down
At stress, point contact, linear contact lay bearing capacity are not as face contact.
2. existing bearing machining required precision is higher, such as angular contact ball bearing, and the requirement on machining accuracy of the present invention
Relatively low, slide mass quantitative requirement used at the same time is less, and 4 slide masses can just meet need of work when minimum.Due to adopting
Its bearing capacity is contacted with face big, although relative friction forces are contacted with linear contact lay more greatly compared to point, but for the agriculture of low speed operation
Industry, heave-load device etc. are under lubrication circumstances again, and the present invention is more or less the same with bearing friction power in the prior art, can meet work
It is required that.Operationally, slide mass can keep geo-stationary to relatively rotate, and it has the advantages that sliding bearing, simultaneously
Also there is bearing.
