摘要	In this paper, distribution characteristics of tooth root bending stress of gear in wind turbine gear transmission are studied. Characteristics of wind speed in the long term and short term, the meshing characteristics and vibration status of single gear teeth are considered for more accurate results. A computing process for tooth root bending stress of gears in wind turbine gear transmission is put forward systematically. A sampling method is put forward by simplifying the relative displacement time series of gear drive to reduce computation load and improve efficiency according to Shannon Theorem and Gear Dynamics. And when the stress is calculated, single gear teeth are regarded as single elements of gear and their meshing processes are considered based on Gear Meshing Theory. At last, the probability density curve of tooth root bending stress of sun gear is derived. Changes of distribution characteristics of tooth root bending stress of sun gear with deviation of gear clearance are discussed at two damping levels. © 2020, Chinese Mechanical Engineering Society.
