201220509364.9, the applying date is：2012.09.26, notification number is：The U of CN 203114902, the day for announcing is：
2013.08.07, its structure is included：Outer ring, roller and retainer, the roller is arranged in the roller holes on retainer, and
Expose retainer, retainer is arranged in outer ring, it is characterised in that：The inner side of the outer ring uniformly offers unidirectional many
Individual stopper slot, the outside of retainer also uniformly has the projection being adapted to stopper slot of equal number；Also have on the retainer
There is reed frame, reed is inserted on reed frame, and the elastic force end of reed offsets with roller.It is disadvantageous in that：Due to the dress
Put without internal ring, be that roller directly contacts with axle, countershaft abrasion is larger, so the quality of lubrication directly determines unilateral bearing
Service behaviour, and correlation circumstance of the equipment not to lubricating is defined and describes.
Utility model content
The purpose of this utility model is in view of the shortcomings of the prior art, there is provided a kind of greasy property is stable and lasting,
Structure more compact and reasonable, the self-lubricating unilateral bearing of long service life.
In order to realize the purpose of above-mentioned utility model, technical solution adopted in the utility model：
A kind of unilateral bearing of self-lubricating, includes the housing of annular, and the end face of housing is offered for fixing end cap
End cap groove, the housing includes integrally formed outer ring and baffle ring, is provided between outer ring and baffle ring for filling oil-containing cotton
Cannelure, baffle ring inner peripheral surface uniformly offers multiple reducing grooves in the same direction, and baffle ring offers some connection reducing grooves and cannelure
Pore, retainer is provided with the inside of baffle ring, retainer outer peripheral face is provided with the positive stop lug boss affixed with baffle ring, keep
Roller is installed in the space that frame, positive stop lug boss and reducing groove are surrounded, roller protrudes from the inner peripheral surface of retainer, the limit convex
Spring leaf is connected with platform, the free end of spring leaf is contradicted in the side of roller.
During utility model works, unilateral bearing is sleeved on axle, the roller on unilateral bearing is contradicted on axle.With
Prior art is compared, and the beneficial effects of the utility model are：Due to there is cannelure in the device, oil-containing cotton can be filled in
In it, and because there are some pores on baffle ring, slowly infiltration is applied to roller surface to be easy to lubricating oil, so as to mitigate roller
Abrasion between axle, it is ensured that the unilateral bearing effectively works.The device can be used as the unilateral bearing of self-lubricating, and it makes
With safe and reliable.
In order to prevent oil-containing cotton from blocking pore, the netted filter ring of laminating baffle ring outer wall is installed with the cannelure.
For the ease of adding lubricant into oil-containing cotton, it is provided with for storing lubrication positioned at the corresponding end cap of cannelure
The annular storage chamber of agent.
Further, the storage chamber is provided with the hydraulic fluid port for adding lubricant.
Further, the end cap periphery is provided with the screw thread spun for end cap.

Specific embodiment
As Figure 1-5, it is a kind of unilateral bearing of self-lubricating, includes the housing 1 of annular, the end face of housing 1 is opened up
There is the groove 104 of end cap 4 for fixing end lid 4, housing 1 includes integrally formed outer ring 101 and baffle ring 102, outer ring 101 and gear
The cannelure 106 for filling oil-containing cotton 5 is provided between ring 102, in order to prevent oil-containing cotton 5 from blocking pore 107, cannelure
The netted filter ring 103 of the laminating outer wall of baffle ring 102 is installed with 106, the inner peripheral surface of baffle ring 102 uniformly offers multiple reducings in the same direction
Groove 105, baffle ring 102 offers the pore 107 of some connection reducing grooves 105 and cannelure 106, and the inner side of baffle ring 102 is arranged
