制造误差会引起齿动载荷,这一点在设计时必须予以考虑。轮齿动载荷可以由一个质量-弹簧模型来估算,估算时考虑节线速度、轮齿刚度和啮合齿轮副的转动质量。设计的齿轮副应该使弯曲和磨损的承载能力至少等于,而通常应大于轮齿所受的最大载荷。遗憾的是轮齿最大载荷的大小是很难知道的。 Manufacturing errors can cause tooth loads, which must be taken into account in design. The gear tooth load can be estimated by a mass-spring model, taking into account pitch speed, gear tooth stiffness and meshing gear pair turning mass. The gear pair should be designed so that the load-bearing capacity for bending and wear is at least equal to, and usually should be greater than, the maximum load on the gear teeth. Unfortunately, the size of the largest gear load is hard to know.
