Shaft sleeve and fastening ring positioning assembly

Abstract

The invention discloses a shaft sleeve and fastening ring positioning assembly. The shaft sleeve and fastening ring positioning assembly comprises a shaft body, a front connecting sleeve and a rear connecting sleeve. The shaft body is provided with a plummer block and a shaft head, and the shaft head is provided with a shaft sleeve. The front connecting sleeve and the rear connecting sleeve are connected and fixed through a connecting piece. A fastening ring and a positioning ring are arranged in the front connecting sleeve. The fastening ring is located at the front end of the front connecting sleeve. The positioning ring is arranged between the fastening ring and the plummer block. A ring arm bent forwards is arranged on the inner circle of the fastening ring, and the end portion of the ring arm is in interference fit with the shaft sleeve. When the front connecting sleeve and the rear connecting sleeve are connected and fixed, the front connecting sleeve drives the fastening ring to move towards the rear end of the shaft sleeve from the front end of the shaft sleeve, the end portion of the front connecting sleeve and the shaft sleeve are in an interference fit state, and therefore the shaft sleeve is clamped on the shaft head under the interaction of the fastening ring and the shaft sleeve, and a very good fixing function is achieved for the shaft sleeve. Meanwhile, due to the fact that the positioning ring is arranged between the fastening ring and the plummer block, the fastening ring can be clamped at the front end of the front connecting sleeve through the positioning ring, and moving of the fastening ring is avoided.

Description

technical field [0001] The invention relates to a shaft sleeve fastening ring positioning assembly. Background technique [0002] The connecting shaft is an important part of the mechanical parts. It is widely used in various fields. When the shaft is assembled, sometimes it needs to be used with a shaft sleeve. The shaft sleeve needs to be connected and fixed with the shaft. The existing connection methods are mostly screws, threads, etc. , the assembly is relatively cumbersome, and threads or threaded holes need to be processed on the parts, which increases the manufacturing cost. Contents of the invention [0003] In view of the above-mentioned technical problems, the object of the present invention is to propose a shaft sleeve fastening ring positioning assembly. [0004] The technical solution of the present invention is realized in the following way: a shaft sleeve fastening ring positioning assembly includes a shaft body, a front connecting sleeve and a rear connec...
