Abstract
The utility model discloses a kind of selfaligning roller bearing depot fat structure, comprise: outer ring, inner ring, a centre rib is provided with at the middle part of described inner ring, roller and retainer is provided with between described outer ring and inner ring, the quantity of described retainer is two panels, this two panels retainer is arranged at the both sides of centre rib and between roller, respectively offers a ramp down angle α in the side end face of described two panels retainer, and the angle of described ramp down angle α is 20-40 degree.By the way, the utility model can make more lubricating grease be stored in the middle of two panels retainer, to improve the lubrication of two panels retainer and retainer and centre rib, slows down the wearing and tearing of copper cage, extends bearing working life.
Description
Technical field
The utility model relates to selfaligning roller bearing field, particularly relates to a kind of selfaligning roller bearing depot fat structure.
Background technique
Selfaligning roller bearing is double-row roller bearing, and under some operating mode, the rotational velocity of two row rollers is likely inconsistent, so just have developed the selfaligning roller bearing of MB structure.The type bearing copper cage is symmetrical two chip copper cages.There is certain gap between two copper cages during design bearing, friction each other can be prevented to a certain extent.Common MB type selfaligning roller bearing is all interior guide structure, and namely the gap of copper cage and inner ring centre rib is less.
Lubricating grease is all annotate from the oil groove of outer ring and oilhole usually.Gap between two panels copper cage is less, is unfavorable for the storage of lubricating grease and lubricating grease is also difficult to enter in the middle of two panels copper cage, is unfavorable for alleviating the dry friction between two panels copper cage, wearing and tearing of slowing down.The gap of copper cage and inner ring centre rib is less, and when bearing operating temperatures raises, inner ring and copper cage all can have expansion to a certain degree, and gap can be less.Copper cage hardness ratio inner ring is low, easily the loss of accuracy because of wearing and tearing, causes bearing noise to strengthen, and shortens bearing life.
Model utility content
The technical problem that the utility model mainly solves is to provide a kind of selfaligning roller bearing depot fat structure, more lubricating grease can be made to be stored in the middle of two panels retainer, to improve the lubrication of two panels retainer and retainer and centre rib, slow down the wearing and tearing of copper cage, extend bearing working life.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: provide a kind of selfaligning roller bearing depot fat structure, comprise: outer ring, inner ring, a centre rib is provided with at the middle part of described inner ring, roller and retainer is provided with between described outer ring and inner ring, the quantity of described retainer is two panels, this two panels retainer be arranged at centre rib both sides and between roller, respectively offer a ramp down angle α in the side end face of described two panels retainer, the angle of described ramp down angle α is 20-40 degree.
Preferably, at described outer ring place, in the middle of two panels retainer, corresponding position offers a greasing hole.
The beneficial effects of the utility model are: the utility model offers a ramp down angle in retainer side end face, can better storing lubricating grease, and more lubricating grease is flow in the middle of two panels retainer and in the gap of retainer and inner ring centre rib; Simultaneously because there is ramp down angle retainer side end face, the friction area of retainer can reduce, and effectively can reduce between two panels retainer and the friction of retainer and inner ring centre rib, slow down the wearing and tearing of copper cage.
Accompanying drawing explanation
Fig. 1 is the sectional view of a kind of selfaligning roller bearing depot fat of the utility model structure one preferred embodiment;
In accompanying drawing, the mark of each parts is as follows: 1, outer ring, and 2, inner ring, 3, retainer, 4, roller, 5, greasing hole, 6, ramp down angle α, 7, centre rib.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection domain of the present utility model.
Refer to Fig. 1, the utility model is embodiment comprise:
A kind of selfaligning roller bearing depot fat structure, comprise: outer ring 1, inner ring 2, the middle part of described inner ring 2 is provided with a centre rib 7, roller 4 and retainer 3 is provided with between described outer ring 1 and inner ring 2, the quantity of described retainer 3 is two panels, this two panels retainer 3 is arranged at the both sides of centre rib 7 and between roller 4, respectively offers a ramp down angle α 6 in the side end face of described two panels retainer 3, and the angle of described ramp down angle α 6 is 20-40 degree.
Further, at described outer ring 1 place, the middle corresponding position of two panels retainer 3 offers a greasing hole 5, and lubricating grease injects from the greasing hole 5 of outer ring 1, increases a ramp down angle α 6 in the side end face of retainer 3, just having more lubricating grease is stored in the middle of two panels retainer 3, during bearing working, lubricating grease can be entered between retainer 3 and inner ring 2 centre rib 7 by the gap of two panels retainer 3, plays lubrication, slow down retainer wearing and tearing, extend bearing working life.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model specification and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
Claims (2)
1. a selfaligning roller bearing depot fat structure, it is characterized in that, comprise: outer ring, inner ring, a centre rib is provided with at the middle part of described inner ring, be provided with roller and retainer between described outer ring and inner ring, the quantity of described retainer is two panels, this two panels retainer be arranged at centre rib both sides and between roller, respectively offer a ramp down angle α in the side end face of described two panels retainer, the angle of described ramp down angle α is 20-40 degree.
