Design research of chassis shaft for children's rotating coffee cup

摘要

In this paper, the chassis shaft of the rotating coffee cup has been designed and checked. The strength of the shaft has been mainly calculated, mechanics model has been established, the shaft force and bearing reaction force have been calculated, the diagrams of torque and bending moment have been mapped, and the connection between thrust ball bearings and the key has been checked. The results of checking calculation provided a good theoretical basis to the structural design of rotating coffee cup.
