Abstract
The utility model discloses a combined type planar thrust needle roller bearing with a dustproof cover. The combined type planar thrust needle roller bearing comprises a rolling body assembly which is formed by combining a needle roller with a retaining frame; and a gasket is respectively mounted on two sides of the rolling body assembly. The combined type planar thrust needle roller bearing with the dustproof cover is characterized in that an outer-edge peripheral turned-over edge is fixed at the outer side of one gasket; the turned-over edge is covered on the rolling body assembly and a disk-shaped dustproof cover at the periphery of the two gaskets; the center of the dustproof cover is provided with an inner hole; the inner hole is provided with an inner turned-over edge; the rolling body assembly and the two gaskets are sleeved on the inner turned-over edge; at least three pressure marks which are used for withholding the gaskets towards outer sides are arranged on the inner turned-over edge; the rolling body assembly and the two gaskets are mutually wrapped to form an integer; and the rolling body assembly can still flexibly rotate between the two gaskets after the rolling body assembly and the two gaskets are wrapped. The combined type planar thrust needle roller bearing with the dustproof cover has good integrity; and the outer edge of the bearing is protected by the dustproof cover, so that impurities are prevented from entering a rolling body, and the service life of the planar thrust needle roller bearing is prolonged.
Description
Technical field
The utility model relates to needle bearing, relates in particular to a kind of combined flat surface needle roller thrust bearing with dust-proof cover.
Background technique
The plane needle roller thrust bearing is a kind of part commonly used in the mechanical rotation.Traditional needle bearing is normally combined by needle roller and retainer, forms the rolling element assembly parts, is furnished with two independent pads respectively in the both sides of rolling element assembly parts.For in the transmission system of open type; Usually the plane needle roller thrust bearing must be tied up three parts or pack with bag or box when dispatching from the factory with belt; The workman when mounted also must a part be enclosed within respectively on the axle, be easy to cause loss, misloading or the neglected loading of pad.When transmission system was open type, impurity such as dust were easy to get in the bearing, as easy as rolling off a logly caused that retainer, needle roller etc. are impaired, also can cause the damage of other part.
The content of model utility
The purpose of the utility model is to overcome the shortcoming that exists in the existing technology, provides a kind of simple in structure, the combined flat surface needle roller thrust bearing of processing, band dust-proof cover easy for installation.
In order to solve the problems of the technologies described above; The utility model is realized through following scheme: it includes the rolling element assembly parts that needle roller and retainer are combined; Both sides at the rolling element assembly parts are separately installed with pad, it is characterized in that being fixed with the outer rim peripheral flanging in the outside of a slice pad, and flange covers the plate-like dust-proof cover of rolling element assembly parts and two pad outer rims; Center at dust-proof cover is shaped on endoporus; Be shaped on in-flanges at endoporus, rolling element assembly parts and two pads are enclosed within on the in-flanges, on in-flanges, are shaped on the impression that at least three places pad is laterally withheld; Rolling element assembly parts and two mutual obvolvents of pad are formed an integral body, and the rolling element assembly parts after the obvolvent still can rotate between two pads flexibly.
Exterior edge face at the pad endoporus in the said outside is shaped on step, and impression is withheld on step.
The combined flat surface needle roller thrust bearing of the band dust-proof cover of making according to such scheme; Utilize the in-flanges resiliently deformable at impression place when mounted; With rolling element assembly parts and two pads conveniently pack into form whole; Good integrity just can not take place in packing, transportation with in using to scatter and disappear and the phenomenon of misloading, neglected loading.Outer rim at bearing has the dust-proof cover protection, has stoped impurity to get in the rolling element, has prolonged the working life of plane needle roller thrust bearing.
Description of drawings
Fig. 1 is the plan view of the combined flat surface needle roller thrust bearing of band dust-proof cover;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the partial enlarged drawing of a-quadrant among Fig. 1.
Among the figure: 1, needle roller; 2, retainer; 3, rolling element assembly parts; 4, pad; 5, flange; 6, dust-proof cover; 7, in-flanges; 8, impression; 9, step; 10, exterior edge face.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to describe.
Fig. 1 is the structural representation of the combined flat surface needle roller thrust bearing of band dust-proof cover.From figure, find out; It includes needle roller 1 retainer 2 spaced-apart with making needle roller 1, is combined into rolling element assembly parts 3, is separately installed with pad 4 in the both sides of rolling element assembly parts 3; Be fixed with outer rim peripheral flanging 5 in the outside of a slice pad 4; Flange 5 covers the plate-like dust-proof cover 6 of rolling element assembly parts 3 and two pad 4 outer rims, is shaped on endoporus at the center of dust-proof cover 6, is shaped on in-flanges 7 at endoporus; Rolling element assembly parts 3 and two pads 4 are enclosed within on the in-flanges 7; On in-flanges 7, be shaped on the impression 8 that six places pad 4 is laterally withheld, rolling element assembly parts 3 and two pad 4 mutual obvolvents are formed an integral body, the rolling element assembly parts 3 after the obvolvent still can rotate between two pads 4 flexibly.
Exterior edge face at pad 4 endoporus in the said outside is shaped on step 9, and impression 8 is withheld on step 9, makes the end face of in-flanges not exceed the exterior edge face of pad 4.
Claims (2)
1. combined flat surface needle roller thrust bearing with dust-proof cover; It includes the rolling element assembly parts that needle roller and retainer are combined; Both sides at the rolling element assembly parts are separately installed with pad, it is characterized in that being fixed with the outer rim peripheral flanging in the outside of a slice pad, and flange covers the plate-like dust-proof cover of rolling element assembly parts and two pad outer rims; Center at dust-proof cover is shaped on endoporus; Be shaped on in-flanges at endoporus, rolling element assembly parts and two pads are enclosed within on the in-flanges, on in-flanges, are shaped on the impression that at least three places pad is laterally withheld; Rolling element assembly parts and two mutual obvolvents of pad are formed an integral body, and the rolling element assembly parts after the obvolvent still can rotate between two pads flexibly.
