对现行机械设计中关于V带传动当量摩擦系数的2种计算公式进行分析。认为其中一种公式是合理的，但存在一定的误差；而另一种公式却是错误的。通过推导V带欧拉公式，给出了计算V带传动当量摩擦系数的准确公式，并在公式中引入了一个新的参数——摩擦力方向角。在考虑皮带拉力变化既有径向滑动又有周向滑动的前提下，改进后的计算公式比现有公式更加完善

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。
