摘　　要：为求解直齿轮时变啮合刚度,运用变增量无限逼近的思想计算齿轮啮合过程中各啮合点位置,将各啮合点位置映射到单个齿廓上;使用材料力学悬臂梁理论计算齿轮时变啮合刚度,并对比势能法及GB/T340-1997中计算所得刚度值。研究结果对准确计算齿轮时变啮合刚度具有重要意义。In order to calculate the time-varying mesh stiffness of spur gear,the gear engaging positions were got by using the variable increment and infinite approximation algorithm.Based on the cantilever beam theory,the time-varying mesh stiffness of spur gear was calculated with gear engaging positions mapping to single tooth profile.The results show that the mesh stiffness is identical with that from GB/T340-1997 and potential energy method.
