Abstract

The invention discloses a bearing with a self-lubricating function. The bearing comprises an outer ring, an inner ring, a rolling body and a retainer which are assembled together, wherein the rolling body is a hollow structure; lubricant is filled in the inner cavity of the rolling body; a plurality of through holes are formed in the side wall of the rolling body; and lubricating grease is filled in the through holes. As the rolling body is set as the hollow structure, is filled with the lubricant inside, and is provided with the through holes in the side wall, the lubricant automatically flows in a rolling way of the bearing along the through holes from the inner cavity of the rolling body in the rotating process of the rolling body to act a lubricating effect among all components in the bearing so as to reduce the loss and to prolong the service life of the bearing; and in addition, the lubricant, flowing out from the rolling body, also can flow in the inner ring of the bearing and a shaft assembled to the inner ring of the bearing along oil holes in the rolling way of the inner ring to act the lubricating effect so as to largely reduce the frictional loss between the inner ring of the bearing and the shaft.

Description

A kind of bearing with self-lubricating function

Technical field

The invention belongs to technical field of bearings, relate in particular to a kind of bearing with self-lubricating function.

Background technique

As everyone knows, bearing is comprised of outer ring, inner ring, retainer and rolling element, and a key factor that affects bearing working life is frictional loss.Friction between friction between friction between rolling element and Internal and external cycle, rolling element and retainer and inner ring and axle etc., these frictions all can loss bearing whole service life, existing remission method is by add lubricant oil, lubricating grease etc. in bearing, but the equipped sealing between each parts of bearing is higher, therefore, lubricating oil filling or lubricating grease enter bearing the inside, difficulty comparatively, and easily by entering into lubricant oil, lubricating grease in bearing, do not drip to and on ground, cause waste.

Summary of the invention

In order to address the above problem, the object of this invention is to provide a kind of bearing with self-lubricating function, this bearing does not need its lubricating oil filling, lubricating grease etc. to be lubricated in the course of the work, and this bearing can lubricating by oneself, greatly improve the working life of bearing, saved manpower labour.

For achieving the above object, the present invention adopts following technological scheme:

A kind of bearing with self-lubricating function, the outer ring, inner ring, rolling element and the retainer that comprise matched together, described rolling element is hollow-core construction, in the inner chamber of rolling element, is filled with lubricant oil, and on the sidewall of rolling element, offer some through holes, in through hole, be provided with lubricating grease.

Further, along circumferentially uniform, offer some oilholes in the raceway of described inner ring.

Owing to adopting technological scheme as above, the present invention has following superiority:

The present invention is made as hollow-core construction by rolling element, Lubricants is filled by portion within it, and offer through hole on its sidewall, so just make rolling element in rotation process, Lubricants voluntarily from rolling element inner chamber along flowing in through hole in the raceway of bearing, to playing lubrication between each parts of bearing inside, reduced loss, improved the working life of bearing; In addition, the Lubricants flowing out in rolling element also can flow into along the oilhole inner ring raceway bearing inner race with the mutually equipped axle of bearing inner race on, play lubrication, greatly reduce the frictional loss between bearing inner race and axle.

Fig. 2 is the structural representation of rolling element;

In Fig. 1: 1-outer ring; 2-inner ring; 3-steel ball; 4-through hole; 5-lubricant oil.

Embodiment

Below in conjunction with drawings and Examples, the present invention is further detailed explanation.

As shown in Figure 1, 2, a kind of bearing with self-lubricating function, the outer ring 1, inner ring 2, rolling element 3 and the retainer that comprise matched together, described rolling element 3 is hollow-core construction, in the inner chamber of rolling element 3, be filled with lubricant oil 5, and on the sidewall of rolling element 3, offer some through holes 4, in through hole, 4 are provided with lubricating grease.

Bearing of the present invention in the course of the work, by the rotation of rolling element 3 self, lubricant oil in rolling element is flow into along through hole 4 in the raceway of inner ring 2 and in retainer, in the situation that rolling element 3 rotates, all can lubricated glossy sliding between rolling element 3 and retainer, between rolling element 2 and inside and outside circle, so just make the whole frictional loss of bearing obtain reducing greatly, effectively extended working life.

In addition, during bearing assembling, in order to prevent that the lubricant oil in rolling element from flowing out in through hole, can in through hole, fill out and establish lubricating grease, and the thickness of lubricating grease can not be too large, prevented on the one hand the outflow of lubricant oil, on the other hand, after bearing assembling, in use, the frictional heating between rolling element and inside and outside circle can make lubricating grease melt as the liquid through hole that flows out, and lubricant oil just can flow out smoothly in through hole like this.

In the raceway of described inner ring, along circumferentially uniform, offer some oilholes.After bearing of the present invention and axle are equipped, along with the rotation of axle, the Lubricants in rolling element flow between axle and inner ring along the oilhole on inner ring after flowing into the raceway of inner ring, plays lubrication, greatly reduces frictional loss.

Claims

1. a bearing with self-lubricating function, the outer ring (1), inner ring (2), rolling element (3) and the retainer that comprise matched together, it is characterized in that: described rolling element (3) is hollow-core construction, in the inner chamber of rolling element, be filled with lubricant oil (5), and on the sidewall of rolling element, offer some through holes (4), in through hole, be provided with lubricating grease.

2. the bearing with self-lubricating function according to claim 1, is characterized in that: in the raceway of described inner ring (2), along circumferentially uniform, offer some oilholes.
