齿轮传动付在正压力作用下,由于齿廓间的滑动所引起的磨损在各个部位是不同的,这不同的磨损程度可用滑动系数来表示,因此滑动系数是齿轮传动质量的重要指标之一。本文的目的在于给出渐开线少齿差行星齿轮传动的滑动系数计算方法,并对滑动系数的变化规律作一初步的分析。 Under the action of positive pressure, the wear caused by the sliding between tooth profile is different in all parts. The different degrees of wear can be expressed by the sliding coefficient. Therefore, the sliding coefficient is one of the important indexes of gear transmission quality. The purpose of this paper is to give the calculation method of the sliding coefficient of the involute less tooth difference planetary gear drive, and make a preliminary analysis of the variation law of the sliding coefficient.
