摘要 依据齿轮传动载荷与轮齿变形的关系,推导出定载荷条件下,修形直齿轮静态传动误差与齿对综合修形参数的关系表达式.提出含制造误差修形齿轮修形参数的确定原则:理论设计修形齿轮的最大综合修形量应能消除含误差齿廓轮齿在啮入和啮出位置产生的几何干涉,理论设计修形齿轮的静态传动误差应保持最小的变化.给出了含制造误差修形直齿轮修形参数的计算公式,阐述了相应的确定方法.系统动态响应计算表明该方法所获得的修形齿轮具有良好的减振效果. Based on the relation between tooth deformation and the transmission load of spur gears, an equation is presented for the correlation between gear static transmission error and the total amount of profile modification of meshing teeth under a specific load. To determine the profile modification parameters for gears with manufacturing errors, a principle is put forward, that is, the maximum profile modification of meshing teeth in designing gears should enable the elimination of the meshing interference caused by manufacturing errors and the variation amount of gear static transmission error should be kept within as a narrow range as possible. Furthermore, formula is provided for determining the profile modification parameters of meshing teeth for spur gears with manufacturing error. Corresponding method for determining the parameters is also proposed. Numerical simulation of system dynamic response indicates that the approach has good effects on vibration reduction of gear transmission.
