传动精度是一项综合性的精度指标.无沦是传动误差还是回差,它们分别是组成系统的传动件、装置件的制造与安装误差,扭转弹性变形、温度变形、运动与载荷因素等在传动中的综合反映.仅就齿轮链的主要运动几何要素而言,传动误差各组成项可归结为:(?)可以证明,在啮合周期内,(?)它是一个零均值、正态分布的广义平稳随机过 Transmission accuracy is a comprehensive precision index. Whether the reduction is transmission error or backlash, they are the components of the transmission system, device manufacturing and installation error, torsion elastic deformation, temperature deformation, movement and load factors in In the gear mesh, the components of the transmission error can be summed up as follows: (?) It can be shown that (?) Is a zero mean and normal distribution The generalized stationary random over
