Abstract
The utility model relates to a bearing with non-symmetrical pockets. The bearing with the non-symmetrical pockets comprises an inner ring, an outer ring, balls and a retainer. A plurality of balls located and connected by the retainer are arranged at intervals between the inner ring and the outer ring and are alternately arranged between the inner ring and the outer ring in a mismatch mode at the same time, and a plurality of pockets matching with positions of the balls are arranged on a periphery of the retainer. The bearing with the non-symmetrical pockets has the advantages of improving radial load adding ability and being convenient to process, low in manufacturing cost and long in service life. The bearing with the non-symmetrical pockets also can be used as a two-row ball bearing, the use number of the balls in the bearing with the non-symmetrical pockets is greatly reduced compared with an ordinary two-row ball bearing, and radial direction load distribution is reduced. In addition, the bearing with the non-symmetrical pockets can bear double-direction axial load, increase bearing inclining degrees, improve limit speed ability and guarantee axial clearance of the ball bearing.
Description
Technical field
The utility model relates to a kind of bearing, particularly a kind of bearing that is provided with asymmetric pocket hole.
Background technique
Deep groove ball bearing is the occasion that is used to bear radial load always.Angular contact ball bearing can bear unidirectional axial load, so angular contact ball bearing generally all is paired use, cost is very big.4 angular contact ball bearings can bear less thrust load, but processing cost is high, friction torque is big.
Summary of the invention
The purpose of the utility model is exactly in order to solve the problem in the background technique, a kind of bearing that is provided with asymmetric pocket hole to be provided, and at the bottom of this bearing not only needs fabricating cost, friction torque is little, but also needs bearing capacity strong.
For achieving the above object; The utility model adopts following technological scheme: a kind of bearing that is provided with asymmetric pocket hole; Comprise inner ring, outer ring, ball and retainer; Be interval with some balls that are located by connecting through retainer between inner ring and the outer ring, each ball alternately shifts to install respectively between inner ring and outer ring, and the circumference of this retainer is provided with some and the pocket hole ball location matches.
For a kind of optimization of the utility model, said retainer is riveted each other by left side and right-hand part and is constituted, and said pocket hole is formed between left side and the right-hand part.
A kind of optimization for the utility model; Be interval with more than half pocket hole, smaller part pocket hole on said left side, the right-hand part respectively successively; On the left side more than half pocket hole mate successively with right-hand part on smaller part pocket hole constitute some pockets hole, and on the left side smaller part pocket hole mate successively with right-hand part on more than half pocket hole constitute all the other some pockets holes.
The utility model is compared with background technique, and when finished product press-fited, the ball that shifts to install between inner ring and outer ring that intersects each other formed the bearing with two movement locus; It has the following advantages: the one, and improve radial load and increase the frame ability; Easy to process, fabricating cost is low, and this bearing can be regarded as two-row ball bearing; And the more common two-row ball bearing of the bearing of this structure, the use number of its ball significantly reduces; Two are to use the life-span long; The 3rd, radial load distributes and reduces; The 4th, can bear the bi-directional axial load; The 5th, increased bearing side degree; The 6th, improve the limit speed ability; The 7th, can guarantee the axial internal clearance of ball bearing.

Embodiment
Embodiment 1: with reference to Fig. 1 ~ 7.A kind of bearing that is provided with asymmetric pocket hole; Comprise inner ring 3, outer ring 1, ball 4 and retainer 2; Be interval with some balls 4 that are located by connecting through retainer 2 between inner ring 3 and the outer ring 1; Each ball 4 alternately shifts to install respectively between inner ring 3 and outer ring 1, and the circumference of this retainer 2 is provided with some and pocket hole 2a ball 4 location matches.Said retainer 2 is made up of through rivet 2b riveted joint left side 2-1 and right-hand part 2-2 each other, and said pocket hole 2a is formed between left side 2-1 and the right-hand part 2-2.Be interval with more than half pocket hole 2a2, smaller part pocket hole 2a1 on said left side 2-1, the right-hand part 2-2 respectively successively; Left side 2-1 goes up more than half pocket hole 2a2 and matees successively and go up smaller part pocket hole 2a1 with right-hand part 2-2 and constitute some pockets hole 2a, and left side 2-1 goes up smaller part pocket hole 2a1 and matees successively and go up more than half pocket hole 2a2 with right-hand part 2-2 and constitute all the other some pockets hole 2a.
The above-mentioned ball 4 that shifts to install between inner ring 3 and outer ring 1 that intersects each other forms the bearing with two movement locus, promptly is provided with the bearing in asymmetric pocket hole.The present invention is more common, and deep groove ball bearing has the following advantages: the one, and improve radial load and increase the frame ability: the bearing that is provided with asymmetric pocket hole can be regarded as two-row ball bearing; And the use number with its ball significantly reduces; The specified dynamic load lotus of ball bearing is
, and the ratio of the rated load of plain bearing and load rating of the present invention is so:
What need understand is: though present embodiment is contrasted in detail to the utility model; But these explanations; It is simple declaration to the utility model; Rather than to the restriction of the utility model, any innovation and creation that do not exceed in the utility model connotation all fall in the protection domain of the utility model.
