| Abstract: In order to study the performance characteristics of linear conjugate tooth profile in the field of planetary gear transmission with small tooth difference, this paper proposes to deduce a mathematical model of linear conjugate planetary gear transmission with small tooth difference. Its dynamic meshing force and vibration characteristics are simulated and analyzed, and the vibration test is conducted for verification. The results show that the reducer performs well, and the maximum error value of the meshing force under several typical working conditions is 7.01%. The vibration acceleration value of the 310,580th node of the fixed internal gear reaches the peak when the gear pair enters the meshing moment. The conclusion verifies that the vibration acceleration of the reducer is positively correlated with input speed and load torque. It provides theoretical basis and practical support for the subsequent application and development of linear conjugate tooth profile in the field of planetary gear transmission with small tooth difference. |
