Abstract
The utility model relates to a bearing retainer. The bearing retainer comprises a first annular rack, a second annular rack and a plurality of pillars arranged between two annular racks for connecting two annular racks, a pocket hole for installing a rolling body is formed between two adjacent pillars, a central hole is formed on the pillar, a bearing roller pin is movably arranged in the central hole, the outer surface of the bearing roller pin is closely contacted with the outer surfaces of rolling bodies arranged in the pocket holes at two sides of the pillar. Through the close contact of the bearing roller pin in the central hole of the pillar and the rolling bodies in the pocket holes at two sides, the sliding friction between the original rolling body and the pillar is changed as the rolling friction between the rolling body and the bearing roller pin, the friction resistance is reduced, the working efficiency of the bearing is improved, and the service life of the bearing is prolonged; and by virtue of the close fit of the bearing roller pin and the rolling body, the centrifugal crowd of the bearing in the retainer in high speed running can be reduced, thereby reducing the noise of the bearing in the motor process and improving the rotation precision of the bearing.
Description
Technical field:
The utility model relates to a kind of retainer.
Background technique:
Pillar and the friction between the rolling element of existing retainer are sliding friction, and surface friction drag is large, the inefficiency of bearing, and working life is short; In addition, the pillar of existing retainer cooperates not tight with rolling element, and when the bearing High Rotation Speed, the centrifugal of retainer collected together greatly, and the on-stream noise of bearing is large, and running accuracy is poor.
The model utility content:
The utility model provides a kind of retainer in order to remedy the deficiencies in the prior art, and its pillar and the surface friction drag between the rolling element are little, has improved the working efficiency of bearing, has prolonged the working life of bearing; Cooperate closely between pillar and the rolling element, reduced the on-stream noise of bearing, improved the running accuracy of bearing, solved problems of the prior art.
The utility model is to solve the problems of the technologies described above the technological scheme that adopts to be:
Retainer, comprise the first toroidal frame, the second toroidal frame and evenly be located at several pillars that are used for connecting two toroidal frames between two toroidal frames, form a pocket hole that is used for installing rolling element between adjacent two pillars, be provided with a center hole at pillar, the movable bearing needle of installing in center hole, the outer surface of bearing needle contacts with the intimate of rolling element in being installed in pillar two side pocket holes.
The diameter of described the first toroidal frame is greater than the diameter of the second toroidal frame, evenly be arranged between two toroidal frames several pillars that connect two toroidal frames and be obliquely installed, the outer surface that is movably arranged on the bearing needle in the center hole on the pillar contacts with the intimate of rolling element in being installed in pillar two side pocket holes.
Be respectively equipped with several blocks at pillar two upper lateral parts, between adjacent two blocks of homonymy, be provided with lubrication groove.
The utility model adopts such scheme, by the rolling element close contact in the bearing needle in the center hole that is located at pillar and the two side pocket holes, change the sliding friction between original rolling element and the pillar between rolling element and the bearing needle rolling friction, reduced surface friction drag, improve the working efficiency of bearing, prolonged the working life of bearing; Closely cooperate between bearing needle and the rolling element, reduced bearing the centrifugal of retainer in high-speed motion and collected together, thereby reduced the noise that bearing produces in movement process, improved the running accuracy of bearing.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is bearing assembling structure schematic representation of the present utility model.
Fig. 3 is the structural representation of Fig. 1 B-C post part.
Among the figure, the 1, first toroidal frame, the 2, second toroidal frame, 3, pillar, 4, the pocket hole, 5, rolling element, 6, center hole, 7, bearing needle, 8, lubrication groove, 9, block.
Embodiment:
For clearly demonstrating the technical characterstic of this programme, below by embodiment, and in conjunction with its accompanying drawing, the utility model is elaborated.
As Figure 1-3, retainer, comprise the first toroidal frame 1, the second toroidal frame 2 and evenly be located at several pillars 3 that are used for connecting two toroidal frames between two toroidal frames, form a pocket hole 4 that is used for installing rolling element 5 between adjacent two pillars 3, be provided with a center hole 6 at pillar 3, at the interior movable bearing needles 7 of installing of center hole 6, the intimate of the rolling element 5 that the outer surface of bearing needle 7 is interior with being installed in 3 liang of side pocket holes of pillar 4 contacts.
The diameter of described the first toroidal frame 1 is greater than the diameter of the second toroidal frame 2, evenly be arranged between two toroidal frames several pillars 3 that connect two toroidal frames and be obliquely installed, the intimate of the rolling element 5 that the outer surface that is movably arranged on the bearing needle 7 in the center hole 6 on the pillar 3 is interior with being installed in 3 liang of side pocket holes of pillar 4 contacts.
Be respectively equipped with several blocks 9 at 3 liang of upper lateral parts of pillar, between adjacent two blocks 9 of homonymy, be provided with lubrication groove 8, can be more easily to the inner oiling of bearing, Effective Raise lubrication effect by lubrication groove 8.
Retainer of the present utility model, by the bearing needle 7 in the center hole 6 that is located at pillar 3 and rolling element 5 close contacts in the two side pocket holes 4, change the sliding friction between original rolling element 5 and the pillar 3 between rolling element 5 and the bearing needle 7 rolling friction, reduced surface friction drag, improved the working efficiency of bearing, prolonged the working life of bearing, under equal conditions, its flexibility of revolution is 2～3 times of traditional retainer; Closely cooperate between bearing needle 7 and the rolling element 5, reduced bearing the centrifugal of retainer in high-speed motion and collected together, thereby reduced the noise that bearing produces in movement process, improved the running accuracy of bearing.
The utility model does not describe part in detail, is those skilled in the art of the present technique's known technology.
