Abstract:
An active design method of tooth profiles for cycloid gears based on their meshing efficiency is proposed. This method takes the meshing efficiency as one of the design variables to determine the tooth profiles. The calculation method for the meshing efficiency of planetary transmission is analyzed and the equation of the meshing efficiency is deduced. Relationships between the meshing efficiency, the radius of the pin wheel and the eccentric distance are revealed. The design constraint quations and the strength constraint quations are deduced. On the basis of this, a design procedure is laid out. Some examples using different input parameters are conducted to demonstrate the feasibility of the approach. A dynamic simulation of the rigid-flexible coupling of cycloid gears is also presented. The results show that the proposed design method is more flexible to control the tooth profiles by changing the input values of the transmission efficiency.
