齿轮箱风冷散热试验

本文首先介绍了利用封闭式齿轮试验台,对齿轮箱进行风冷散热试验的条件,经多次试验所采集的在不同载荷同一风速;不同风速同一载荷两种情况下的试验数据。其次,根据试验数据计算出齿轮箱的风冷导热系数,以及它同风速的关系式,并进行了分析和对比。最后还介绍了工业用风扇不同叶片数的风速测定,并通过分析利用“当量风速”的概念得出有关实用价值的结论。

Experimental research on the wind cooling radiator of the gear case

This paper introduces the experiment conditions under which the gear case is investigated by using a closed gear testing machine. The experiments are repeated many times. The expernment data are collected for two situations, one with changing loading but constant wind velocity and the other with constant loading but changing wind velocity. In addition, according to the data derived from the experiments and the wind cooling heat conductivity factor of the gear case, the relation between this factor and the wind velocity is derived, and the results are analysed. Finally, the introduction is presented into the wind velocity measurement results of the industrial fan for different models of the fan blades. The results are analysed by using the concept called the equivalent velocity with valuable conclusions reached.
