Abstract

The utility model relates to a one-way bearing with a spring nylon holding rack. The one-way bearing comprises a bearing outer ring and a bearing inner ring between which are a roller pin holding rack and a spherical holding rack, wherein, steel balls are arranged on the axial inner side of the spherical holding rack, and roller pins are arranged on the axial inner side of the roller pin holding rack. The one-way bearing provided by the utility model is characterized in that elastic bodies are arranged on the axial inner side of the roller pin holding rack; one side of each elastic body is fixedly connected with the roller pin holding rack, and the other side is in contact with the corresponding roller pin; each elastic body consists of a left elastic part and a right elastic part; one end of each elastic part is integrally connected with the roller pin holding rack, and the other ends bend to form contact cambered surfaces to be in contact with the roller pins; and the elastic bodies and the roller pin holding rack adopt an integrated structure. The one-way bearing provided by the utility model adopts an integrated structure of a spring structure and the holding rack, so the procedure of mounting the spring mutually is eliminated, accordingly, the product processing efficiency is greatly improved and the manufacturing cost is reduced.

Description

Unilateral bearing with spring nylon cages

Technical field

The utility model relates to a kind of unilateral bearing with novel retainer, especially a kind of unilateral bearing with spring nylon cages.

Background technique

Concerning present bearing manufacturing, the kind of bearing is more, and the bearing of some specific uses also uses comparatively extensive; Especially a kind of needle-type unilateral bearing; In the washing machine industry, use particularly outstandingly, the unidirectional running through bearing realizes the work of washing machine.And for the working principle of existing unilateral bearing; Like Fig. 1～shown in Figure 3; Reach a stop requirement through needle roller 8, lasso inclined-plane 9, S template spring 10 threes; But in actual course of working, artificial installation S template spring 10 seriously restricts the manufacturing efficiency and the production capacity of this type of unilateral bearing, becomes the bottleneck operation of producing this class bearing already; And problems such as adding spring occurs leaking through regular meeting,, finally influence the function of use and the life-span of bearing to such an extent as to the needle roller discontinuity influences bearing stop performance and runnability.

Summary of the invention

The purpose of the utility model is to overcome the deficiency that exists in the existing technology; A kind of unilateral bearing with spring nylon cages is provided, no longer needs artificial mounting spring, can stop less spring-loaded phenomenon; Effectively enhance productivity and production capacity; Can also guarantee that spring, needle roller, retainer are triangular stressedly evenly makes bearing reach the stop performance requirement of expection, guarantees the stable performance of bearing.

The technological scheme that provides according to the utility model; Said unilateral bearing with spring nylon cages; Comprise bearing outer ring and bearing inner race; Cages for needle and spherical retainer are arranged between said bearing outer ring and bearing inner race, be provided with steel ball, be provided with needle roller in the axial inboard of said cages for needle in the axial inboard of said spherical retainer; Characteristic is: the axial inboard at said cages for needle is provided with elastomer, and a said elastomeric side is fixedly connected with cages for needle, and opposite side contacts with needle roller.

Said elastomer is made up of left and right two-part elastic member of symmetry, and an end and the cages for needle of said elastic member are linked as an integral body, and the other end bending of elastic member forms contacting surface and contacts with needle roller.

Said elastomer and cages for needle are as a whole.

Said elastomer adopts nylon material to process.

The utlity model has following advantage:

(1) spring structure of the utility model and retainer are integral structure, have cancelled the operation of artificial mounting spring, thereby have improved the efficient of product processing greatly, have reduced cost of production;

(2) the utility model can solve less spring-loaded problem effectively, thereby improves the usability of product, the working life of finally improving bearing;

(3) the described retainer of the utility model is simple and reliable for structure.

Embodiment

Below in conjunction with concrete accompanying drawing the utility model is described further.

Like Fig. 4 ~ shown in Figure 7: the unilateral bearing with spring nylon cages comprises bearing outer ring 1, bearing inner race 2, needle roller 3, steel ball 4, cages for needle 5, elastomer 6, spherical retainer 7 etc.

The utility model comprises bearing outer ring 1 and bearing inner race 2; Cages for needle 5 and spherical retainer 7 are arranged between said bearing outer ring 1 and bearing inner race 2; Axial inboard at said spherical retainer 7 is provided with steel ball 4, is provided with needle roller 3 in the axial inboard of said cages for needle 5; Axial inboard at said cages for needle 5 is provided with elastomer 6, and a side of said elastomer 6 is fixedly connected with cages for needle 5, and opposite side contacts with needle roller 3; Said elastomer 6 is as a whole with cages for needle 5, and said elastomer 6 adopts nylon material to process;

Said elastomer 6 is made up of left and right two-part elastic member of symmetry, and an end and the cages for needle 5 of said elastic member are linked as an integral body, and the other end bending of elastic member forms contacting surface and contacts with needle roller 3.

It is fixing after the described bearing outer ring 1 with unilateral bearing of spring nylon cages of the utility model assembles through steel ball 4 and spherical retainer 7 with bearing inner race 2; And needle roller 3 is pressed in the groove of bearing outer ring 1 after assembling with cages for needle 5, thereby is fixed on bearing inside.On cages for needle 5, be fixedly connected with elastomer 6; Elastomer 6 substitutes the effect of spring of the prior art; Not only can realize the normal operation and the stop performance of unilateral bearing, and can solve the low problem with neglected loading of the efficient of artificial mounting spring, can also guarantee simultaneously elastomer, needle roller, retainer triangular stressed evenly; Make bearing reach the stop performance requirement of expection, guarantee the stable performance of bearing; And can improve the working life of bearing.
