Abstract
The utility model discloses a kind of bearing with self-lubricating function, comprise the outer ring of matched together, inner ring, rolling element and retainer, described rolling element is hollow-core construction, lubricant oil is filled with in the inner chamber of rolling element, and some through holes are offered on the sidewall of rolling element, be provided with lubricating grease in through hole.Rolling element is set to hollow-core construction by the utility model, fill Lubricants therein, and through hole is offered on its sidewall, so just make rolling element in rotation process, Lubricants voluntarily from rolling element inner chamber along flowing in the raceway of bearing in through hole, play lubrication between each parts of Bearing inner, reduce loss, improve the working life of bearing; In addition, the Lubricants flowed out in rolling element also can flow into bearing inner race and on the axle that is equipped with mutually with bearing inner race, play lubrication, greatly reduce the frictional loss between bearing inner race and axle along the oilhole inner ring raceway.
Description
Technical field
The utility model belongs to technical field of bearings, particularly relates to a kind of bearing with self-lubricating function.
Background technique
As everyone knows, bearing is made up of outer ring, inner ring, retainer and rolling element, and the key factor affecting bearing working life is frictional loss.Friction between rolling element and Internal and external cycle, the friction between rolling element and retainer and the friction etc. between inner ring and axle, these frictions all can the whole service life of loss bearing, existing remission method is by adding 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 inside bearing, comparatively difficulty, and easily the lubricant oil do not entered in bearing, lubricating grease are dripped on ground and cause waste.
Summary of the invention
In order to solve the problem, the purpose of this utility model is to provide a kind of bearing with self-lubricating function, and this bearing does not need to lubricate its lubricating oil filling, lubricating grease etc. in the course of the work, and this bearing can lubricating by oneself, substantially increase the working life of bearing, save manpower labour.
For achieving the above object, the utility model adopts following technological scheme:
A kind of bearing with self-lubricating function, comprise the outer ring of matched together, inner ring, rolling element and retainer, described rolling element is hollow-core construction, in the inner chamber of rolling element, be filled with lubricant oil, and some through holes are offered on the sidewall of rolling element, be provided with lubricating grease in through hole.
Further, circumferentially uniformly in the raceway of described inner ring some oilholes are offered.
Owing to adopting technological scheme as above, the utility model has following superiority:
Rolling element is set to hollow-core construction by the utility model, fill Lubricants therein, and through hole is offered on its sidewall, so just make rolling element in rotation process, Lubricants voluntarily from rolling element inner chamber along flowing in the raceway of bearing in through hole, play lubrication between each parts of Bearing inner, reduce loss, improve the working life of bearing; In addition, the Lubricants flowed out in rolling element also can flow into bearing inner race and on the axle that is equipped with mutually with bearing inner race, play lubrication, greatly reduce the frictional loss between bearing inner race and axle along the oilhole inner ring raceway.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
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 utility model is described in further detail.
As shown in Figure 1, 2, a kind of bearing with self-lubricating function, comprise the outer ring 1 of matched together, inner ring 2, rolling element 3 and retainer, described rolling element 3 is hollow-core construction, lubricant oil 5 is filled with in the inner chamber of rolling element 3, and on the sidewall of rolling element 3, offering some through holes 4, in through hole, 4 are provided with lubricating grease.
Bearing of the present utility model in the course of the work, by the rotation of rolling element 3 self, the lubricant oil in rolling element is made to flow in the raceway of inner ring 2 and in retainer along through hole 4, when rolling element 3 rotates, all can lubricatedly glossyly to slide between rolling element 3 and retainer, between rolling element 2 and inside and outside circle, so just make the overall frictional loss of bearing obtain to reduce greatly, effectively extend working life.
In addition, during bearing assembling, flow out in through hole to prevent the lubricant oil in rolling element, can fill out in through hole and establish lubricating grease, and the thickness of lubricating grease can not be too large, prevents the outflow of lubricant oil on the one hand, 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 liquid state flows out through hole, and such lubricant oil just can flow out smoothly in through hole.
Circumferentially uniformly in the raceway of described inner ring offer some oilholes.After bearing of the present utility model and axle are equipped with, along with the rotation of axle, flow between axle and inner ring along the oilhole on inner ring after the Lubricants in rolling element flow into the raceway of inner ring, play lubrication, greatly reduce frictional loss.
