Technical Field

The utility model relates to a clamp spring, in particular to an anti-rotation clamp spring and a connecting structure applied to the same.

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 is a steel part and the sleeve is an aluminum part, the clamp spring and the sleeve can be abraded after relative rotation, and the cleanliness of the whole machine is affected.

Disclosure of Invention

The utility model aims to solve the technical problem of providing an anti-rotation clamp spring and a connecting structure applied by the anti-rotation clamp spring, wherein the anti-rotation clamp spring is reasonable and simple in structure, the connecting structure cannot generate relative abrasion, the cleanliness of the whole machine is ensured, and the product performance is improved.

In order to solve the technical problems, the technical scheme of the utility model is as follows: an anti-rotation clamp spring comprises a clamp spring sheet body, wherein the clamp spring sheet body is provided with an opening and is C-shaped; the clamp spring sheet body is at least provided with an anti-rotation part, and the anti-rotation part extends along the axial direction of the clamp spring sheet body.

As the preferred technical scheme, at least one end part of the clamp spring sheet body is bent axially to form the anti-rotation part.

As preferred technical scheme, two tip of jump ring lamellar body all carry out the axial bending and form and prevent changeing the portion, and two prevent changeing the portion and extend to the same side of jump ring lamellar body.

The connecting structure applying the anti-rotation clamp spring further comprises a sleeve, wherein an inner spline is arranged on the inner wall of the sleeve, and an annular clamp spring groove is formed in the inner spline; the clamp spring sheet body is positioned in the clamp spring groove, and the anti-rotation part is clamped in the tooth groove of the internal spline.

As a preferred technical scheme, the connecting device further comprises an inner gear ring, wherein an outer spline is arranged on the outer wall of the inner gear ring and is matched with the inner spline to realize the connection between the inner gear ring and the sleeve; the sleeve is further provided with a limiting table, and the limiting table and the clamp spring sheet body are clamped on two end faces of the inner gear ring respectively to limit the axial direction of the inner gear ring.

Prevent changeing the jump ring setting and prevent changeing the portion, cooperate with the internal spline on the sleeve, can prevent that the jump ring from rotating, and then avoid the relative rotation between jump ring and the sleeve, avoid wearing and tearing, guarantee the cleanliness of complete machine.

Detailed Description

As shown in fig. 1, the anti-rotation snap spring 1 includes a snap spring sheet body 11, and the snap spring sheet body 11 has an opening and is C-shaped. The clamp spring sheet body 11 is provided with an anti-rotation part 12, and the anti-rotation part 12 extends along the axial direction of the clamp spring sheet body 11.

Preferably, at least one end of the snap spring sheet body 11 is bent axially to form the rotation preventing portion 12.

Further, two end parts of the clamp spring sheet body 11 are axially bent to form anti-rotation parts 12; and the two anti-rotation parts 12 extend to the same side of the clamp spring sheet body 11.

As shown in fig. 2, the connection structure using the anti-rotation snap spring 1 further includes a sleeve 2 and an inner gear ring 3, as shown in fig. 3 and 4, the inner gear ring 3 and the sleeve 2 are connected through splines, that is, an inner spline 22 is arranged on the inner wall of the sleeve 2, and an outer spline is arranged on the outer wall of the inner gear ring 3 and is matched with the inner spline 22 to connect the inner gear ring 3 and the sleeve 2. An annular clamp spring groove 23 is formed in the inner spline 22, the clamp spring sheet body 11 is located in the clamp spring groove 23, and the rotation preventing portion 12 extends into a tooth groove 24 between two key teeth of the inner spline 22.

As shown in fig. 2 and 4, the sleeve 2 is further provided with a limiting table 25, and the limiting table 25 and the clamp spring sheet body 11 are clamped on two end faces of the inner gear ring 3 respectively to limit the axial direction of the inner gear ring 3.

The foregoing shows and describes the general principles, essential features, and advantages of the utility model. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the utility model as claimed.
