Description

Clamp spring and connecting structure applied by same

Technical Field

The utility model relates to a clamp spring, in particular to a clamp spring and a connecting structure applied to the clamp spring.

Background

The circlip is also called retainer ring or retainer ring, belongs to a kind of fastener, and is used for being installed in the shaft groove or hole groove of machine and equipment, and plays the role of preventing the axial movement of the parts on the shaft or hole. When the clamp spring and the clamp spring groove rotate relatively, abrasion is caused.

Disclosure of Invention

The utility model aims to solve the technical problem of providing a clamp spring and a connecting structure applied by the clamp spring, which can avoid abrasion between the clamp spring and a clamp spring groove and have good dynamic balance performance.

In order to solve the technical problems, the technical scheme of the utility model is as follows: a clamp spring comprises a clamp spring main body, wherein the clamp spring main body is C-shaped; the clamp spring main body is at least provided with a limiting bulge, and the limiting bulge is positioned at the outer edge of the clamp spring main body; in the radial direction of jump ring main part, spacing arch is outside extension.

As an optimal technical scheme, the limiting protrusion and the clamp spring main body are of an integrated structure.

As an optimal technical scheme, in the circumferential direction of the clamp spring main body, the limiting protrusions are symmetrically arranged with the opening of the clamp spring main body.

Use connection structure of above-mentioned jump ring, still include outer hub, be equipped with two jump ring grooves on the inner wall of outer hub, the tank bottom in every jump ring groove all is equipped with the spacing groove, and the jump ring main part is located the jump ring inslot, and spacing arch stretches into the spacing inslot, and spacing arch and spacing groove mutually support, and it is spacing to the rotation of jump ring.

As a preferred technical scheme, the hub is further provided with a sleeve, an inner spline is arranged on the inner wall of the outer hub, an outer spline is arranged on the outer wall of the sleeve, and the outer spline is matched with the inner spline to realize the connection between the outer hub and the sleeve; two jump rings cooperate and are respectively clamped on two end faces of the external spline of the sleeve to limit the axial direction of the sleeve.

As a preferred technical scheme, the two limiting grooves are symmetrically arranged in the circumferential direction of the outer hub.

The relative rotation of the clamp spring and the outer hub is limited through the limiting protrusion and the limiting groove, so that the clamp spring and the outer hub can be prevented from being abraded. Two jump rings are used in a matched mode, and the dynamic balance performance of the connecting structure is improved obviously.

In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without creative efforts.

FIG. 1 is a schematic structural diagram of a clamp spring;

FIG. 2 is a schematic structural view of a connection structure;

FIG. 3 is a schematic structural view of the outer hub from a first perspective;

fig. 4 is a structural schematic view of the outer hub from a second perspective.

Detailed Description

As shown in fig. 1, the clamp spring 1 includes a clamp spring main body 11, and the clamp spring main body 11 is C-shaped and has an opening; the clamp spring main body 11 is at least provided with a limiting bulge 12, and the limiting bulge 12 is located at the outer edge of the clamp spring main body 11 and extends outwards. Preferably, the limiting protrusion 12 extends radially outward of the clamp spring body 11 and is integrated with the clamp spring body 11.

Preferably, the limiting protrusion 12 is disposed opposite to the opening of the clamp spring main body 11, i.e., a central angle between the limiting protrusion and the opening is 180 °.

As shown in fig. 2, 3 and 4, the connecting structure using the snap spring 1 further includes an outer hub 2 and a sleeve 3. Be equipped with internal spline 24 on the inner wall of outer hub 2, be equipped with external spline on the outer wall of sleeve 3, realize outer hub 2 and sleeve 3's connection with the cooperation of internal spline 24.

Be equipped with two jump ring grooves 22 on the inner wall of outer hub 2, the tank bottom of every jump ring groove 22 is equipped with spacing groove 23, and jump ring main part 11 is located jump ring groove 22, and spacing arch 12 stretches into spacing groove 23, and spacing arch 12 and spacing groove 23 mutually support, and are spacing to jump ring 1's rotation.

Two jump rings 1 cooperate and use, block respectively on two terminal surfaces of the external spline of sleeve 3, and it is spacing to the axial of sleeve 3. Experiments prove that after the two clamp springs 1 are symmetrically assembled, the dynamic balance is obviously improved, so that the limiting grooves 23 of the two clamp spring grooves 22 are symmetrically arranged in the circumferential direction of the outer hub 2, namely the central angles of the projections of the two clamp spring grooves 22 on the cross section of the outer hub 2 are 180 degrees.
