摘要
为了解决少齿差内啮合弹性啮合效应系数是个变量问题,提出了偏曲轴少齿差行星减速器最大承载能力的概念,以单齿的齿根应力达到疲劳弯曲强度为出发点,建立各齿对的法向间隙与虚拟啮合点、最大承载能力之间数学关系,并基于Matlab对该减速器最大承载能力进行估算,且通过实例及其实验加以验证,同时研究了中心距对计算结果影响。结果表明,该方法提高了设计效率,并充分考虑弹性变形对提高承载能力影响,降低了成本。
In order to solve the problem that the elastic mesh effective coefficient of internal gear pair with few teeth difference is variable, this paper presented the concepts of the maximum load-carrying capacity of planetary gear reducer of less tooth difference with biasing crankshaft, it had to be taken as starting that the root stress of single tooth reaches bending fatigue strength, the relationships were established mathematically among normal clearance of the tooth pairs, the virtual engaging point and the maximum load-carrying capacity, the maximum load-carrying capacity of planetary gear reducer of less tooth difference with biasing crankshaft was estimated on base of Matlab, and verified with living example and experiment, at the same time we have studied the effect of center distance on the calculation results. The result shows that the method improves design efficiency, and reduces the cost; it is fully considered that the elastic deformation has influence on increasing the caring capacity.
