Abstract
The utility model belongs to the technical field of bearings and relates to a holder of a unidirectional combined bearing. The holder comprises a hollow ring-shaped left-side plate, a hollow ring-shaped right-side plate, and roller clapboards that are used for connecting the left-side plate and the right-side plate and uniformly distributed on the circumference; the same side of the lower edge of each roller clapboard is provided with a spring installation platform in the same direction; a roller position-limiting hole is arranged between the spring installation platform and the adjacent clapboards; the external diameter of the left-side plate is greater than that of the right-side plate; the opposite surface of the spring installation platform at the lower part of the same clapboard is an arc-shaped concave surface; the right-side plate between two adjacent clapboards or the upper part of the clapboard is provided with convex positioning aimers; and positioning ribs are arranged between the positioning aimers. The holder has the advantages that the holder is tightly matched with the roller components arranged at the external ring, the rollers are not easy to slip from the holder, furthermore, the external ring of the bearing and the holder can not be installed reversely, the positioning is accurate and reliable, and the working failure of a clutch caused by installation error or reverse installation of the combined holder and the roller is avoided.
Description
Technical field
The utility model belongs to technical field of bearings, refers in particular to a kind of unidirectional set and closes bearing cage.
Background technique
At present, clutch and unidirectional combination bearing (the following unified unilateral bearing that is called for short) retainer is used to be installed between the outer ring and inner ring of unilateral bearing, a plurality of springs, a plurality of rollers are placed in the spacing hole of unidirectional retainer, existing unilateral bearing retainer only is provided with the fin that coincide substantially with clutch outer inclined working (cambered surface) on side plate, with the clamping of unilateral bearing outer ring, this retainer cooperates because of being subjected to outer ring inner working face structure Design to influence restriction with the outer ring, be difficult to accomplish accurate location---increase the difficulty that matching allowance will cause installation, Spielpassung will cause that again the position of retainer roller is inaccurate, after long-time the use, cause cooperation pine more easily, even retainer loses locating function and cause clutch to lose efficacy.In addition in process of production, the workman is installing this unilateral bearing retainer in unilateral bearing, sometimes accidentally can unilateral bearing oppositely and retainer be installed together, make the clutch operational failure.
Summary of the invention
The purpose of this utility model provides that a kind of retainer cooperates with the outer ring closely with roller assembly, roller is difficult for slippage from retainer, outer race and retainer can not oppositely be installed, the reliable unidirectional set of accurate positioning is closed bearing cage.
The purpose of this utility model is achieved in that unidirectional set closes bearing cage, include hollow, the left sideboard of annular, right sideboard and connect left sideboard and the uniform roller dividing plate on circumference of right sideboard, the same side in each roller dividing plate bottom is provided with the spring mounting platform in the same way, be provided with the roller spacing hole between spring mounting platform and the adjacent dividing plate, the external diameter of left sideboard is greater than the external diameter of right sideboard, the opposite of the spring mounting platform of same the lower partition is circular-arc concave surface, right sideboard between adjacent two dividing plates is provided with the location standard of projection, is provided with the location fin between the standard of location.
Above-mentioned location fin can regular even distribution or random distribution on right sideboard.
Above-mentioned location standard is the arc of projection or semicircle or other triangle, trapezoidal etc. how much shape.
Above-mentioned location fin is extended on the right sideboard by dividing plate and is wide with dividing plate, and the location fin exceeds the lower dents between the adjacent two location standards.
Above-mentioned unidirectional set is closed bearing cage and is made with plastic materials.
The outstanding compared to existing technology advantage of the utility model is:
1, the one side of the utility model dividing plate is circular-arc concave surface, and roller cooperates closely, and roller is difficult for slippage from retainer, and long-play also is difficult for producing loosening, the high working efficiency of machinery;
2, the dividing plate between each location standard of the utility model is provided with the location fin, the unilateral bearing outer ring cooperates the fin and the location standard of the retainer of unilateral bearing to have arc groove and a slit, because the position of arc groove and slit relation, make unilateral bearing and retainer quality of fit height and anti-dress not advance, the unilateral bearing that makes is working properly, long service life;
3, when the utility model inner and outer rings supporting and the production and assembly of retainer roller, stopped the phenomenon at the bottom of the accuracy of mounting point with it, the up-to-standard rate height of product, cost of production reduces.
Description of drawings
Fig. 1 is an overall structure schematic representation of the present utility model;
Fig. 2 is a sectional view of the present utility model;
Fig. 3 is the sectional view that cooperates unidirectional set sympodium bearing outer-ring of the present utility model.
Embodiment
The utility model is further described with specific embodiment below in conjunction with accompanying drawing, referring to Fig. 1-3:
