Abstract
An asymmetric self-aligning roller bearing cage back sloped structure belongs to the field of bearing manufacturing. Because the back design of a cage is provided with a slope, the contact area of the two-body cage is reduced to the max, the oil storage spaces of both end surfaces of the bearing cage are enlarged, consequently, the lubricating property of a bearing is greatly improved, and the service life of the bearing is prolonged.
Description
Technical field
The utility model relates to a kind of asymmetric selfaligning roller bearing retainer back side band ramp structure, belongs to bearing and makes the field.
Background technique
Present asymmetric selfaligning roller bearing extensively model is used for the mine electromechanical equipment, and wherein a part of mine electromechanical equipment rotating ratio is higher, and it is also bigger to load; During the big load operation of the high rotating speed of asymmetric biserial selfaligning roller bearing; Be prone to produce moment unbalance loading phenomenon, two row rollers and retainer rotating speed are different, and two back sides of two body retainers produce friction each other; Heat up owing to lubricate and cool off the bad bearing that causes, the too high meeting of bearing temperature causes and reduces the working life of bearing or bag axle phenomenon.
Summary of the invention
Defective in view of the prior art existence; The purpose of the utility model provides a kind of contact friction area that can reduce when two body retainers are stressed to rotate; Improve the greasy property of bearing, improve the bearing asymmetric selfaligning roller bearing retainer back side band ramp structure in working life.
For realizing above-mentioned purpose, the technical solution that the utility model adopted mainly is: a kind of asymmetric selfaligning roller bearing retainer back side band ramp structure is characterized in that: be with a slope in the design of the back side of retainer.
A kind of asymmetric selfaligning roller bearing retainer back side band ramp structure; Its beneficial effect is: reduce two body retainer area of contact to greatest extent; Increase the oil storage space of retainer both ends of the surface, thereby improved the greasy property of bearing greatly, improved the working life of bearing.
Description of drawings
Fig. 1 is the structural representation that improves the rear bearing structure;
Reference character is following: 1, retainer, 2, the slope.
Embodiment
Among Fig. 1, be with a slope 2 in the design of the back side of retainer 1.
A slope 2 is with according to Products in Series and size design in the back side of two body retainers 1; Two body retainers, 1 area of contact is reduced, see shown in Figure 1ly, form a V-type groove in the middle of two retainers; Make retainer that the space of an oil storage has been arranged like this, improved the greasy property of bearing.The size dimension on concrete slope calculates as follows:
KC=（DC-dC）×?
；α1=α2。
Claims (2)
1. an asymmetric selfaligning roller bearing retainer back side band ramp structure is characterized in that: be with a slope (2) in the design of the back side of retainer (1).
2. a kind of asymmetric selfaligning roller bearing retainer according to claim 1 back side band ramp structure is characterized in that: said slope (2) concrete size dimension calculates as follows:
KC=（DC-dC）×
；α1=α2。
