Abstract—

The article describes the problems of existing methods for assessing the durability of involute gears (IGs) associated with determining the maximum permissible wear and predicting the occurrence of sudden failure. The relationship of dynamic indicators with wear processes in IGs is described, which makes it possible to predict resource limitation by the nature of the growth of the dynamic coefficient due to the increase in the probability of jamming. The results of the analysis of the amplitude-frequency response of the transmission by the fast Fourier transform method are presented, which allowed us not only to evaluate the dynamism of the transmission with different lubricants, but also to rank these materials by their extreme pressure action depending on the magnitude of the loading moment, at a given limit value of the dynamic coefficient. It is shown that as the antifriction properties of the lubricant increase, the growth of the dynamism coefficient decreases as the loading moment increases (when using a film-forming additive, the limiting value of the dynamism coefficient is reached at a loading torque of 2.47 N m, and in the case of using pure synthetic oil, the limiting value of the dynamism coefficient is reached at a loading torque of 2.39 N m), this in turn leads to an increase in the maximum permissible wear and to an increase in the resource according to the wear criterion (in the case of using synthetic oil with a film-forming additive, the IG resource is 10–11 times higher than in the case of using pure synthetic oil).The dependence of the amplitude of the torque oscillations on the high-speed shaft of the IG transmission on the type of lubricant is revealed. Analytical dependences of the dynamic coefficient on the load for different lubricants are obtained. The dependence of the wear limit on the type of lubricant is proposed. A new method of predicting the resource of an IG is proposed taking into account the growth of the dynamic coefficient.

使用成膜润滑剂时渐开线齿轮的动态参数评价和耐磨性改进

摘要——

本文描述了现有渐开线齿轮 (IG) 耐久性评估方法的问题，这些方法与确定最大允许磨损和预测突发故障的发生相关。描述了动态指标与IG磨损过程的关系，这使得可以通过由于干扰概率的增加而导致的动态系数增长的性质来预测资源限制。给出了通过快速傅立叶变换方法对变速器的幅频响应进行分析的结果，这使我们不仅能够评估使用不同润滑剂的变速器的动态性，而且还可以根据它们的极压作用对这些材料进行排名取决于在给定的动态系数极限值下的负载力矩的大小。获得了不同润滑剂的动态系数对负载的分析依赖性。提出了磨损极限对润滑剂类型的依赖性。考虑到动态系数的增长，提出了一种预测IG资源的新方法。
