Abstract

The prediction of churning power loss has been a difficult problem in the analysis of spur gears. Thus, an analytical prediction model based on the redefinition of churning power loss and energy transformation is proposed to estimate the churning power of spur gears. Churning power loss is defined as the combination of the power loss due to the drag on the end face, the power loss due to the tangential flow, the power loss due to the acceleration of lubricants in the tooth space, and the power loss due to the centrifugal force. Several comparisons of prediction and experimental results are made and good agreement of those is obtained. Finally, the components of churning power loss under different gears and work conditions are analyzed, and the influences of each part on churning power loss are obtained.

正齿轮搅动功率损失的新型预测模型

搅动功率损失的预测一直是正齿轮分析中的一个难题。因此，本文提出了一种基于搅动功率损失重新定义和能量转换的分析预测模型，用于估算正齿轮的搅动功率。搅动功率损失被定义为端面阻力导致的功率损失、切向流导致的功率损失、齿间润滑油加速度导致的功率损失以及离心力导致的功率损失的组合。对预测结果和实验结果进行了多次比较，结果一致。最后，分析了不同齿轮和工作条件下搅动功率损失的组成部分，并得出了各部分对搅动功率损失的影响。
