[Abstract]:The presence of the planetary gear manufacturing error is not only serious damage to the planet wheel running the load characteristics, has a great impact on planetary gear parts of the fatigue life and reliability. In a variety of manufacturing errors, the planetary frame axle hole position error is the power of the planetary wheel flow and load sharing characteristics of the maximum error form, will seriously alter the dynamic characteristics and fatigue properties of planetary gear. The relationship between shaft hole position error of the planetary wheel are load and life is the core part of wind turbine gearbox design for high reliability, this paper will take the fan gear box planetary gear train as the research object, study on the shaft hole of the planet carrier to carry out the position error the wind turbine gearbox planetary wheel load characteristics and service life influence. Based on the 1.5MW wind turbine gearbox planetary gear train as the main research object, the shaft hole position error of the planet carrier of the wind turbine gearbox line Analysis of influence of star system theory, in order to determine the dynamic characteristics of wind turbine and power flow gear planetary gear train mechanism, mathematical model and wind turbine planetary gear structure characteristics based on the established dynamics and power 1.5MW fan planetary gear flow model, the shaft hole position error are loading effects on planetary gear train the failure mechanism and the key parts of the planetary gear dynamics modeling. According to the existing methods, build a planetary dynamics simulation model of 1.5MW wind turbine, shaft hole position error analysis for simulation of the load sharing effect. The multi-body dynamics simulation software based on MSC.ADAMS platform, builds a virtual shaft hole position error of the planetary wheel load were studied the influence of the shaft hole position error of the planetary wheel load sharing coefficient results, obtained the load failure of the key parts of the spectrum, laid the foundation for the subsequent analysis of life The different forms of foundation. The position error impact on the results and the finite element method based on finite element simulation of planetary wheel bearing structures using nonlinear finite element software Abaqus analysis platform, a variety of shaft hole position error of the planetary wheel bearing and analysis of stress distribution and life influence, get the stress and strain the results of the failure of key parts. And based on Roessle and Fatemi theory and the hardness of the direct method, established the strain life curve and surface of bearing gear within the obtained position of key parts and failure failure failure time, failure assessment of key parts of life. Finally, through the 1.5MW gear box, a wind power gear box's failure case examples to explain the research.
