V带传动预紧力的精确计算

Accurate Calculation for the Advance Tension of V-belt Drive

分析了现有V带传动预紧力计算公式存在不足,预紧力值偏小,带速越高,小的越多。对高速V带传动用现有预紧力计算公式是不合适的。给出了预紧力的精确计算公式,为高速V带传动的设计计算提供了切合实际的理论依据。

The paper analysed the calculation formula which was now being used for the advance tension of V-belt drive,and pointed out that the formula was not accurate.The higher the velocity of V-belt,the smaller the calculated value was.It was not suitable that the calculation formula now being used for the advance tension of higher velocity V-belt was utilized.The paper gave the accurate formula for calculating the advance tension of V-belt drive.The given formula supplied the theoretical bases for the practice of designing calculation of higher velocity V-belt drive.It had important significance.
