Abstract: The elastic ring is commonly used to limit the axial direction of the part in the transmission. Because of the accumulation of manufacturing errors of axial parts, there is the axial clearance after assembly. When there is a changing axial force on the part, the axial clearance can cause move and shock of the part, which can cause early failure and damage of the part and the elastic ring, and ultimately lead to the failure of the transmission. But this paper proposed that the application of conical elastic ring can effectively solve the above problems. Firstly, the structure, principle and advantages of conical elastic ring are described. Secondly, the force analysis of the conical elastic ring is carried out. The design ideas and methods of the conical elastic ring and its groove are analyzed, and the case applications are listed. Finally, the design method and application advantages of conical elastic ring are summarized to provide a better solution for the limit of axial direction of the part in the transmission.
