Development of Design System for Spatial Cam Reducer

Based on the excellent kinetic characteristic of the spatial cam mechanism, a kind of cam reducer is designed. First, a digital prototype of the reducer is built. Then, the multi-rigid body dynamics simulation is performed, and the driven disk motion curve and the contact force and contact torque curves are output. After verifying the correctness and feasibility of the design parameters by analyzing the simulation results, the design idea of the CAD system of the space cam reducer is established. The development of the CAD system of the space cam reducer was completed by using the Visual C++ compiler language and the secondary development tool Protoolkit. The computer aided design of the reducer is realized. Finally, the digital prototypes of spatial cam reducer are established by means of this system. It can make the design of reducer faster and easier by handing the repetitive design process and complicated calculation work to the system.
