本文首先介绍了作者推导的中心轮与行星轮,行星轮与内齿轮滑动系数及其最大值的计算公式.并根据齿轮传动磨损计算的原理,分析了中心轮、行星轮和内齿轮的磨损情况,给出了齿厚磨损量不超过许用值的正常工作时间计算方法。许多 NGW 型行星传动装置在低速重载下齿轮磨损严重,导致附加动载荷增加,振动和噪音增大从而加速了机件损坏。由于机架结构复杂,一般齿宽又较小,齿宽方向的偏载情况与齿轮的布置和轴及机架的刚性有关(参阅[6]表1—6),与齿宽系数有关.由于篇幅所限,本文只讨论齿廓厚度磨损计算,为此先研究滑动系数计算.
In this paper, firstly, the authors deduce the formulas of the sliding coefficient and its maximum of the center wheel and the planet wheel, the planet wheel and the internal gear deduced by the author, and analyze the wear of the center wheel, the planet wheel and the internal gear according to the calculation principle of the gear transmission wear , Given the tooth thickness wear does not exceed the allowable value of the normal working hours calculation method. Many NGW type planetary gear wear seriously under low speed and heavy load, resulting in additional dynamic load, vibration and noise increase and thus accelerate the mechanical damage. Due to the complex structure of the frame, the tooth width is generally smaller, and the partial load in the tooth width direction is related to the gear arrangement and the rigidity of the shaft and the frame (refer to Table 1-6 in [6]), which is related to the tooth width coefficient Space limitations, this article only discusses the calculation of tooth profile thickness wear, first study sliding coefficient calculation.
