Theoretical and experimental studies on tooth mesh stiffness calculations of a pair of spur gears with machining errors and tooth modifications

利用三维有限元软件，成功地对一对存在加工误差和修形的直齿圆柱齿轮进行了载荷接触分析和啮合刚度计算。该软件不仅可用于计算齿轮的啮合刚度，还可用于分析齿轮副存在齿形偏差、齿距误差、修形和修形时的齿面接触应力和齿根弯曲应力。

Special software has been developed successfully to conduct loaded tooth contact analysis and tooth mesh stiffness calculations of a pair of spur gears with machining errors and tooth modifications using three-dimensional, finite element method. This software not only can be used to calculate the tooth mesh stiffness, but also can be used to analyze tooth contact stresses and root bending stresses when the pair of gears has tooth profile deviations, tooth pitch errors, tooth profile modification and lead modification.
