润滑

At the same time, in the transmission system of construction machinery up-to-date, the power transferred by the transmission is improved greatly, while the gear friction is adopted in the transfer structure, so the heat loss will influence both the lubrication and cooling of the system, and the working intensity of the structure components. Therefore, the correction of the heat balance is necessary to the system.

同时，在现代工程机械的变速传动系统中，由于行星变速箱所传递的功率有了大幅的提高，但传递结构依然大量采用齿轮摩擦传动，其热损失不仅对系统的润滑和冷却有影响，而且对结构元件的工作强度也具有很大的影响，因此，也需要对该系统进行热平衡校核。

Based on the measurement of noise of an idling lathe C630,the effects of gear tooth friction on change gear noise,and the relation between friction excitation frequency and gearing frequency were analyzed.

以一台C630车床空转噪声的测试数据为依据，分析了齿面摩擦对车床挂轮噪声的影响，以及摩擦激励频率与齿轮啮合频率的关系，并通过涂油润滑降低挂轮噪声的实验对此进行了验证。
