Rear receding combined connecting shaft

Abstract

The invention discloses a rear receding combined connecting shaft. The rear receding combined connecting shaft comprises a shaft body. A front shaft head is arranged at the front end of the shaft body, and a rear shaft head is arranged at the rear end of the shaft body. A pillow block is arranged between the front shaft head and the shaft body. The diameter of the shaft body is larger than those of the front shaft head and the rear shaft head. The diameter of the pillow block is larger than that of the shaft body, and the pillow block is provided with straight knurling. A rear receding bevel angle is arranged at the end, close to the rear shaft head, of the shaft body. A rear oil groove is formed in the connecting position of the shaft body and the rear shaft head. According to the rear receding combined connecting shaft, the pillow block is arranged between the shaft body and the front shaft head, the straight knurling is arranged on the pillow block for matching assembly, and there is no need to install a shaft sleeve additionally. Moreover, the rear receding combined connecting shaft is integrally shaped, there is no need to connect multi-segment shafts for installation, and therefore cost is reduced, and efficiency is improved. The receding bevel angle at the rear end of the shaft body can relieve collisional deformation and losses happening during assembly. Furthermore, due to the arrangement of the rear oil groove, the overall loss in working can be greatly lowered.

Description

Technical field [0001] The invention relates to a rear avoidance combined connecting shaft. Background technique [0002] The connecting shaft is an important part of mechanical parts. It is widely used in mechanical equipment. The connecting shaft can connect multiple parts to integrate them. However, the general connecting shaft can only connect two parts at both ends. When multiple parts are combined and connected, and the connection structure is relatively complicated, it is often necessary to use multiple connection shafts and cooperate with auxiliary parts such as shaft sleeves, resulting in low assembly efficiency and waste of resources. Summary of the invention [0003] In view of the above-mentioned technical problems, the purpose of the present invention is to provide a rear avoidance combined connecting shaft. [0004] The technical solution of the present invention is realized as follows: a rear avoidance combined connecting shaft includes a shaft body, the front end of...
