Abstract ：
In this paper, a calculation model for accurately determining the results of the multi-tooth meshing-in impact force of cycloidal pin gear transmission in rotate vector reducer was proposed. Firstly, the principle of multi-tooth meshing-in impact of cycloidal pin gear transmission mechanism under load was explained, and meshing-in velocity was derived. Secondly, a meshing-in impact force model considering damping force and the meshing-in impact coefficient was proposed based on the Hunt-Crossley contact collision model and the Hertz contact collision curve. The study investigated the influence of different modification methods, eccentricity and cycloidal revolution speed on the impact force. Subsequently, an optimization mathematical model was constructed to optimize the basic design parameters of cycloidal gear, with the meshing-in impact coefficient of cycloidal pin gear transmission as the objective. Finally, the impact force model and the optimal mathematical model were verified using finite element analysis. The maximum error of impact force between the theory and simulation results is 3.53%, which is within the allowable range and proved the feasibility of the meshing-in impact model. The results demonstrate that the optimized cycloidal pin gear transmission effectively reduces the impact coefficient.

Abstract ：
This paper studies the bearing capacity of the cycloid-pin gear drive mechanism in a rotate vector reducer. First, the concept of standard deviation in statistics was introduced to calculate the load distribution coefficient, combined with the contact strength analysis theory and the multitooth contact load analysis theory of cycloid-pin gear drives, and a calculation model of the bearing capacity of the cycloid-pin gear drive mechanism was established. Then, based on the bearing capacity calculation model, the influence of the design parameters on the bearing capacity of the cycloid-pin gear drive mechanism was systematically explored. Finally, taking the bearing capacity of the cycloid-pin gear drive mechanism as the optimization objective, a multiobjective genetic algorithm was used to optimize the design parameters, a more accurate optimization model of the bearing capacity of the cycloid-pin gear drive mechanism was established, and the theoretical calculation was verified by finite element analysis. The results show that the bearing capacity of the cycloid-pin gear drive mechanism is effectively improved after optimization.

Abstract ：
The effect of center distance error of machine tool employed in machining globoidal cam was discussed. Based on the offset surface theory, the equation of the globoidal cam profile and the mathematical model of the profile error were established, and the sensitivity coefficient of the center error was derived. The variation of the sensitivity coefficient corresponded to different tool paths was further investigated. The real profile and profile error were simulated through VC++ and PROE software, and the impact and collision of the globoidal cam mechanism caused by the center distance error and its generation mechanism were revealed. Results show that the center error degrades meshing quality and has a bad influence on the transmission performances.
