零齿差齿轮输出机构耐磨损设计的研究

Research on Wear-Resistance Design on Output Mechanism in Zero Tooth Difference

针对零齿差齿轮输出机构的润滑状态及磨损判断等问题,首次将EHL理论应用于零齿差齿轮输出机构中并推导出计算公式,可以通过对零齿差齿轮输出机构的油膜厚度和膜厚比的计算,判断该输出机构的润滑状态及磨损程度;为零齿差齿轮输出机构的耐磨损设计提供了必要的理论依据。

For the first time, EHL theory is applied in the output mechanism of zero tooth difference and deduced the EHL calculation formula in order to solve the lubrication state and abrasion degree of zero tooth difference wear output mechanism. By means of calculating the oily membrane depth and the membrane depth ratio of zero tooth difference, the lubrication state and abrasion degree is deduced. All of these are a reliable basis for output mechanism of zero tooth difference in wear - resistance design.
