Abstract During their lifetime, gears may undergo starved lubrication operating conditions. Starvation has an impact on friction between gears and leads to modified gearbox efficiency. In this article, lubricant starvation tests on an FZG test rig adapted to this condition are presented. Gears were equipped with an embedded thermocouple sensor to measure their operating bulk temperature. An experimental method to isolate the test box power loss of the FZG machine is proposed. A thermal model of this test rig draws up the power loss distribution into the test box for a nominal condition of lubrication. A numerical method based on experimental results is proposed to estimate gear power loss variation during lubricant starvation.

FZG 试验台的热建模:在缺乏润滑条件下的应用

摘要 在其使用寿命期间,齿轮可能会经历润滑不足的操作条件。饥饿会影响齿轮之间的摩擦并导致变速箱效率的改变。在本文中,介绍了在适合该条件的 FZG 试验台上进行的润滑剂饥饿试验。齿轮配备了嵌入式热电偶传感器以测量其工作整体温度。提出了一种隔离FZG机试验箱功率损耗的实验方法。该测试台的热模型将功率损耗分布绘制到测试箱中,用于标称润滑条件。提出了一种基于实验结果的数值方法来估计润滑剂不足期间齿轮功率损失的变化。
