在行星传动中,功率的传递是由牵连运动和相对运动来完成的。在研究计算行星传动的效率时,假设只计算与相对运动有关的齿轮啮合损失,并且认为这部分损失与相当的定轴传动相同,而和牵连运动有关的损失都忽略不计。计算行星传动效率的方法虽然不少,实际使用较多的只有两种。一种是分步计算损失法,此法概念明确,直观,对简单行星传动用起来比较方便。另一种是法,此法引入动力学传动比的概念,对复杂的行星传动来说,简便易行,有很大的优越性。以上两种方法计算结果常有差异。本文对两种效率的计算方法进行比较,分析了其内在的联系,并找出产生差异的原因以及修正方法。
In planetary transmission, power transfer is done by implicating and relative motion. In studying the efficiency of calculating planetary transmissions, it is assumed that only the gear meshing losses associated with relative motion are calculated, and this loss is considered to be the same as for comparable fixed-axis drives, with negligence associated with implicated motion. Although there are many ways to calculate the planetary transmission efficiency, only two are actually used. One is a step-by-step loss calculation method, the concept of a clear and intuitive concept, simple planetary transmission is more convenient to use. The other is the law, this method introduces the concept of dynamic transmission ratio, complex planetary drive, easy, with great advantages. The above two methods are often different results. This article compares the two methods of calculating efficiency, analyzes their intrinsic relations, and identifies the causes of the differences and the corrections.
