Abstract
A kind of conical bearing retainer structure, belongs to field of bearings.The utility model comprises a frusto-conical annular body, it is along the circumferential direction evenly distributed with multiple fenestra, the hole wall at described fenestra four angles is respectively arranged with the grease groove of through frusto-conical annular body inner peripheral surface and outer circumferential face, lubricating grease forms lubricating loop by grease groove at tapered roller body periphery, reduce tapered roller body and interior, the friction of outer ring, by the rolling of tapered roller body, the raceway that lubricating grease can be transported to outer ring and inner ring lubricates, formed from grease groove to tapered roller body again to interior, the lubrication passages of outer ring, make bearing race surface and rolling element constantly can carry out Oil Film Compensation, reduce the friction of bearing, reduce the heating value of bearing, improve the working life of bearing, the utility model solves between fenestra in existing retainer and tapered roller body does not have sufficient gap supplying lubricating grease lubricate thus affect the problem in bearing working life.
Description
Technical field
The utility model belongs to field of bearings, especially relevant with a kind of conical bearing retainer structure.
Background technique
Conical bearing comprises outer ring, inner ring, retainer and tapered roller body, and retainer is provided with equally distributed multiple fenestra, and tapered roller body is installed in fenestra, and outer ring and inner ring are by tapered roller body driven rotary.For reducing the rolling friction between tapered roller body and inside and outside circle; usually lubricating grease can be adopted to lubricate; but after existing tapered roller body is mounted to fenestra; owing to there is no sufficient gap between tapered roller body and the fenestra of retainer; make that lubricating grease is more difficult when bearing High Rotation Speed accomplishes timely lubrication to tapered roller body, the time one is long, causes pivot friction to aggravate; make the temperature of bearing increase, reduce the working life of bearing.
Model utility content
The purpose of this utility model is intended to overcome between fenestra in existing retainer and rolling element does not have sufficient gap supplying lubricating grease lubricate thus affect the defect in bearing working life, there is provided a kind of lubricating grease can lubricate in rolling element periphery loop, reduce friction, improve the conical bearing retainer structure in bearing working life.
For this reason, the utility model is by the following technical solutions: a kind of conical bearing retainer structure, comprise a frusto-conical annular body, it is along the circumferential direction evenly distributed with multiple fenestra, it is characterized in that, the hole wall at described fenestra four angles is respectively arranged with the grease groove of through frusto-conical annular body inner peripheral surface and outer circumferential face, lubricating grease forms lubricating loop by grease groove at tapered roller body periphery, reduce tapered roller body and interior, the friction of outer ring, by the rolling of tapered roller body, the raceway that lubricating grease can be transported to outer ring and inner ring lubricates, formed from grease groove to tapered roller body again to interior, the lubrication passages of outer ring, make bearing race surface and rolling element constantly can carry out Oil Film Compensation, reduce the friction of bearing, reduce the heating value of bearing, improve the working life of bearing.
The utility model can reach following beneficial effect: by arranging grease groove on the hole wall at fenestra four angles of retainer, lubricating loop is formed at rolling element periphery, by the rolling of tapered roller body, formed from grease groove to tapered roller body again to the lubrication passages of inside and outside circle, make bearing race surface and tapered roller body constantly can carry out Oil Film Compensation, reduce the friction of bearing, reduce the heating value of bearing, improve the working life of bearing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.
As shown in Figure 1, the utility model comprises a frusto-conical annular body 2, it is along the circumferential direction evenly distributed with multiple fenestra 3, the hole wall at four angles of described fenestra 3 is respectively arranged with the inner peripheral surface of through frusto-conical annular body 2 and the grease groove 1 of outer circumferential face, lubricating grease forms lubricating loop by grease groove 1 at tapered roller body periphery, reduce tapered roller body and interior, the friction of outer ring, by the rolling of tapered roller body, the raceway that lubricating grease can be transported to outer ring and inner ring lubricates, formed from grease groove 1 to tapered roller body again to interior, the lubrication passages of outer ring, make bearing race surface and rolling element constantly can carry out Oil Film Compensation, reduce the friction of bearing, reduce the heating value of bearing, improve the working life of bearing.
