摘要：
Given the bottleneck problems of the domestic RV reducer, such as low bearing capacity, low motion accuracy, and short service life, the distribution function of meshing backlash between cycloid gear and pin gear is constructed on the basis of the characterization method of the cycloid gear surface modification. The load distribution between the cycloid gear and the pin gear under the action of the load is studied systematically, and the determination method of the maximum meshing force between the cycloid gear and the pin gear is proposed. Combined with contact strength analysis theory and multitooth contact load analysis theory of cycloid-pin gear drive, the bearing capacity evaluation model of the cycloid-pin gear transmission mechanism is established. In addition, the influence of eccentricity on the bearing capacity of cycloid-pin gear transmission is explored. Results show that as the eccentricity increases within a certain range, the bearing capacity coefficient of the cycloid-pin gear increases first and then decreases, reaching the highest when the eccentricity is 0.98 mm. Ultimately, its accuracy is verified through finite element analysis. © 2022, Editorial Department of Journal of HEU. All right reserved.
