The technological scheme that realizes the object of the invention is: a kind of unilateral bearing, have inside and outside lasso,, inside and outside lasso, between be provided with plastic cage, evenly be provided with special-shaped wedge groove and spring groove on retainer one end face, be provided with special-shaped voussoir in each special-shaped wedge groove, be provided with spring in the spring groove to special-shaped voussoir; Evenly be provided with the roll piece groove on the retainer other end, be provided with roll piece in each roll piece groove; Be coated with respectively on the both ends of the surface of retainer plastic cover plate; The two side of the special-shaped wedge groove of described retainer is respectively arc surface and plane, and the nearly inside race of planar wall place is provided with chamfering; The corresponding inside and outside lasso of described special-shaped voussoir, both ends of the surface be respectively outer convex arc surface,, the both sides of corresponding cell wall are respectively plane and interior concaved circular cambered surface, form an outstanding arc round angle at the nearly inside race place of interior concaved circular cambered surface, spring one end that is arranged in the spring groove pushes on the arc round angle of special-shaped voussoir; Retainer and cover plate, between the interlocking.
Roll piece quantity on the retainer of above-mentioned unilateral bearing is identical with special-shaped voussoir quantity, is 8 to 12, and roll piece and special-shaped voussoir cross-like are provided with.
The roll piece of above-mentioned unilateral bearing adopts spin.
The retainer of above-mentioned unilateral bearing is provided with on the end face of special-shaped wedge groove and evenly is provided with jack, covers cover plate on this end face and is provided with the projection that jack therewith cooperates; Retainer is provided with on the end face of roll piece groove and evenly is provided with projection, and the cover plate that covers on this end face is provided with the jack that cooperates with this projection; Projection on described retainer and the cover plate insert respectively realize in the jack on cover plate and the retainer retainer and cover plate, between interlocking.
The retainer of above-mentioned unilateral bearing and the projection on the cover plate are formed by cylinder and column cap, and the shape of column cap can be spherical or conical, and the base diameter of column cap is greater than column diameter.
The cover plate that covers on retainer abnormity voussoir one end face of above-mentioned unilateral bearing is provided with the spring groove lid that cooperates with the retainer spring groove.
The utlity model has positive effect:
(1) the utility model forms an outstanding arc round angle at the nearly inside race place of the interior concaved circular cambered surface of special-shaped voussoir, one end of spring pushes on the arc round angle of special-shaped voussoir, the spring force that acts on the special-shaped voussoir changes slightly, the abnormity voussoir can become rotation, make to the utlity model has good sensitivity, and can bear bigger moment of torsion.(2) adopt the interlocking that matches between projection and the jack between retainer of the present utility model and the cover plate, spring is seated in the spring groove, so processing, installation and removal all make things convenient for, and the column cap of projection adopts spherical or conical, the base diameter of head is greater than column diameter, so be connected firmly, can not take place influences sealability, low noise because of the phenomenon of retainer and annular cover plate misalignment.(3) maintenance is convenient in the interlocking between the utility model retainer and the cover plate, increases the service life.
