[Abstract]:Multistage planetary gear transmission is widely used as a transmission device in many industrial fields. Its dynamic performance seriously affects the reliability and service life of the transmission device.Because of the manufacturing and installation error of the components, the clearance will appear in the gear meshing pair and the rolling bearing, and the existence of the clearance will seriously affect the dynamic performance of the gear system in the working process.This paper presents a severe challenge to the stability and working life of the transmission device, and it is necessary to adopt a reasonable load sharing device in the structural design.Therefore, this paper focuses on the dynamic characteristics and load equalization of XE93 type wind turbine variable propeller reducer. The main work is as follows:The dynamic model of multi-degree-of-freedom variable propeller reducer system is established. The meshing stiffness of gear teeth is calculated by Shi Chuan method. The modal analysis method is described and applied to solve the vibration equation of the system.The modal of the system and the vibration displacement response of the member are obtained according to the example parameters.The main errors affecting the load sharing performance of the system are analyzed. According to the statics load average calculation model and the design conditions, the calculation formula of the average load coefficient considering the floating component is derived in detail.Through MATLAB programming calculation, the variation diagram of load average coefficient with time is obtained under the condition of component floating, and the influence of different floating type of component on load average coefficient is analyzed.The load average coefficients of the first stage of each component are calculated under the condition of its eccentricity error acting alone and the working conditions of many different input speeds.The original dynamic model is modified and the effect of error excitation is taken into account in the modified dynamic model.The vibration equations of solar wheel, planetary wheel and planetary structure are established, and the stiffness matrix and damping matrix of the system are derived according to the vibration equations of each component.The Fourier method is introduced to solve the system equation. By MATLAB programming, the dynamic load coefficient and the average load coefficient are obtained, respectively. The influence of the main parameters such as meshing stiffness and eccentricity error on the load sharing performance of the system is analyzed.The dynamic simulation of the system is carried out with the help of ADAMS software. The time domain response of the meshing force of each planetary gear and the vibration displacement response of the planetary gear are analyzed in the output speed and the third stage transmission.
