Abstract
The invention discloses an elastic retainer ring for a hole. The elastic retainer ring comprises a retainer ring base body and is characterized in that the outer edge of the retainer ring base body is provided with a thickening layer, and an inner arc-shaped face is arranged on the upper surface of the retainer ring base body. The elastic retainer ring for the hole is simple in manufacture process, reasonable in structure and good in elasticity, original plane contact is changed into the inner arc-shaped face contact, stress for fixing parts is effectively reduced, accordingly fixing is form, positioning is accurate, the service life of the elastic retainer ring is prolonged by means of the thickening layer, and work efficiency is improved.
Description
Technical field
The present invention relates to a kind of mechanical fastener, particularly a kind of circlip for hole.
Background technique
In lathe and various machinery, circlip commonly used fixes the part on axle, as bearing, gear etc.We know, due to the very thin thickness of circlip, and circlip often is close to the part that is fixed, and the surface of contact of circlip and retaining element is the plane, and surface of contact is less, and the stress that produces during retaining element uses is larger, and easily loosening, it is unreliable to locate.
Summary of the invention
Technical problem for above-mentioned existence the objective of the invention is: proposed a kind of circlip for hole that can effectively reduce the applied stress of retaining element.
Technical solution of the present invention is achieved in that a kind of circlip for hole, comprises the back-up ring matrix, it is characterized in that: described back-up ring matrix outer is provided with thickening layer; Described back-up ring body upper surface is provided with a concave profile.
Preferably, the degree of depth of described concave profile is 1～3mm.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Circlip for hole of the present invention, manufacturing process is simple, rational in infrastructure, the back-up ring good springiness has changed original plane contact into the intrados contact, effectively reduces the applied stress of retaining element, thereby make fixed, accurate positioning, and improved its working life by the design of thickening layer, increased working efficiency.
Description of drawings
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
Accompanying drawing 1 is the plan view of circlip for hole;
Accompanying drawing 2 is the A-A view of circlip for hole;
Wherein: 1, back-up ring matrix; 2, concave profile; 3, thickening layer.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described.
Accompanying drawing 1,2 is a kind of circlip for hole of the present invention, comprises back-up ring matrix 1, and described back-up ring matrix 1 outer is provided with thickening layer 3; Described back-up ring matrix 1 upper surface is provided with a concave profile 2; The degree of depth of described concave profile 2 is 1mm.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Circlip for hole of the present invention, manufacturing process is simple, rational in infrastructure, the back-up ring good springiness has changed original plane contact into the intrados contact, effectively reduces the applied stress of retaining element, thereby make fixed, accurate positioning, and improved its working life by the design of thickening layer, increased working efficiency.
Above-described embodiment only is explanation technical conceive of the present invention and characteristics; its purpose is to allow person skilled in the art scholar can understand content of the present invention and be implemented; can not limit protection scope of the present invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
Claims (2)
