摘要 根据基于分形接触模型的齿轮接触强度理论,讨论了影响齿轮接触强度大小的几个参数:粗糙度幅值参数、材料的特性参数、分形维数和表面粗糙度。结果表明:减小粗糙度幅值参数、增大材料的特性参数有利于提高齿轮接触强度;分形维数和表面粗糙度与接触强度之间不是线性关系,而是存在一个最优值。 According to the gear contact strength theory based on fractal contact model,several pa- rameters which influence the gear's contact strength were discussed herein. These parameters included roughness amplitude parameters, material property parameters, fractal dimension, and the surface roughness. Results show that reducing the roughness amplitude parameters and improving the materi- al parameters can improve the gear's contact strength. Fractal dimension and surface roughness don't meet the linear relationship with contact strength, and exist an optimal value when the contact strength gets a minimum value.
