Mechanical assembly is an important part of the mechanical manufacturing pro-cess,and the quality of assembly directly affects the performance and service life of the product.The traditional cross shaft type universal coupling joint assembly adopts the way of assembling after grinding the retaining ring,which requires high dimensional accuracy of the relevant parts,and the long cycle of grinding the retaining ring,which seriously affects the production schedule,and does not meet the requirements of the modern industrial high-quality development.Through in-depth study of the application of group assembly method in the design of retaining ring,the calculation method of group design of retaining ring and the feasibility of its selection and checking are verified.The optimized design of the joint reduces the machining difficulty of the relevant parts,shortens the assembly cycle,and improves the flexibility of assembly and the qualification rate of the assembly.
