<正>带传动的效率是由三部分决定:1)带的弹性和弹性滑动;2)空气摩擦;3)轴承摩擦。在许多情况下,为了减少输入功的损失,有必要计算带传动的最有利效率。本文将给出计算最有利效率的方法。

The efficiency of belt drives depends on three parts: (1) elasticity of belt and elastic creep; (2) air friction; (3) bearing friction. There is a great need for the calculation of most adventageous efficiency of belt drives to re-duce the loss of input power. So the article is presented for this purpose.
