[0002] Shaft parts are one of the typical parts often encountered in hardware accessories. They are mainly used to support transmission parts, transmit torque and bear loads. According to the different structural forms of shaft parts, they can generally be divided into three categories: smooth shafts, stepped shafts and special-shaped shafts; or divided into solid shafts, hollow shafts, etc. The structural design of the shaft is to determine the reasonable shape and all structural dimensions of the shaft, which is an important step in shaft design. It is composed of the type, size and position of the parts installed on the shaft, the fixing method of the parts, the nature, direction, size and distribution of the load. It is related to factors such as the type and size of the bearing, the blank of the shaft, the manufacturing and assembly process, installation and transportation, and the deformation of the shaft. Common shafts can be divided into crankshafts, straight shafts, flexible shafts, solid shafts, hollow shafts, rigid shafts, and flexible shafts (flexible shafts) according to the structural shape of the shaft.

[0003] During the use of shaft products, oil seals are usually required for sealing. Currently, existing oil seals are usually fixed on the surface of shaft products. When the oil seal is damaged, it cannot be disassembled and replaced in time, which is a defect. Utility Model Content
