Abstract
The utility model discloses a combined type plane needle roller thrust bearing, which comprises a rolling body assembly part combined by a needle roller and a retainer. Two gaskets are installed respectively on both sides of the rolling body assembly part. The combined type plane needle roller thrust bearing is characterized in that chamfers or stairs are produced on the outer end faces of the outer edges of the two gaskets. Fixing sleeves are wrapped on the outer edges of the two gaskets and the rolling body assembly part, inward turn-ups are produced at both ends of the fixing sleeves, and the turn-ups enable the rolling body assembly part and the two gaskets to be closed to form an integral body at the position of the chamfers or the stairs, and the closed rolling body assembly part can still flexibly rotate between the two gaskets. By the adoption of the combined type plane needle roller thrust bearing, phenomena of loss, wrong installation and short-ship cannot occur during packing, transportation and use processes. When the retainer of the plane needle roller thrust bearing is damaged, damage to other parts due to dropping of the needle roller cannot be caused due to the fact that the fixing sleeve enables the needle roller to be wrapped between the closed gaskets.
Description
Technical field
The utility model relates to needle bearing, relates in particular to a kind of combined flat surface needle roller thrust bearing.
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.Usually the plane needle roller thrust bearing when dispatching from the factory must with belt three parts are tied up or with bag or box pack, what the workman when mounted also must a part is enclosed within respectively on the axle, is easy to cause loss, misloading or the neglected loading of pad.In addition, when the retainer in the needle roller thrust bearing of plane was impaired, needle roller will come off, and the needle roller that comes off just is easy to cause the damage of other parts.
The model utility content
The purpose of the utility model is to overcome the shortcoming that exists in the existing technology, provides a kind of simple in structure, processing, combined flat surface needle roller thrust bearing 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; Be separately installed with two pads in the both sides of rolling element assembly parts; It is characterized in that being shaped on chamfering or step in the exterior edge face of said two pad outer rims, be enclosed with fixed cover in the outer rim of rolling element assembly parts and two pads, the two ends of fixed cover are shaped on inside flange; Flange forms an integral body in chamfering or step place with rolling element assembly parts and two mutual obvolvents of pad, and the rolling element assembly parts after the obvolvent still can rotate between two pads flexibly.
According to the combined flat surface needle roller thrust bearing that such scheme is made, after obvolvent, form wholely, just can not take place in packing, transportation with in using to scatter and disappear and the phenomenon of misloading, neglected loading.When the retainer in the needle roller thrust bearing of plane is impaired,, can not cause the damage of other parts because of needle roller comes off because fixed cover is wrapped in needle roller in the middle of two pads of obvolvent.
Description of drawings
Fig. 1 is the plan view of combined flat surface needle roller thrust bearing.
Among the figure: 1, needle roller; 2, retainer; 3, rolling element assembly parts; 4, pad; 5, chamfering; 6, step; 7, fixed cover; 8, flange.
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 combined flat surface needle roller thrust bearing.From figure, find out; It includes the rolling element assembly parts 3 that needle roller 1 and retainer 2 are combined; Be separately installed with two pads 4 in the both sides of rolling element assembly parts 3, one pad 4 is shaped on chamfering 5 in the exterior edge face of said two pad 4 outer rims, and another pad 4 is shaped on step 6; Outer rim at rolling element assembly parts 3 and two pads 4 is enclosed with fixed cover 7; The two ends of fixed cover 7 are shaped on inside flange 8, and flange 8 forms an integral body with step 6 places with rolling element assembly parts 3 and two pad 4 mutual obvolvents in chamfering 5, and the rolling element assembly parts 3 after the obvolvent still can rotate between two pads 4 flexibly.
