液压马达的输出力矩和驱动轴的微量转动之间的关系对起动力矩的测量来说是很重要的。本文的前半部分研究这一关系。后半部分讲述用五种不同的方法测量三种不同形式的马达的起动力矩。研究结果表明,如果考虑到输出力矩和驱动轴微量转动之间的关系,则起动力矩的测量值是与测量方法无关的。 The relationship between the output torque of the hydraulic motor and the slight rotation of the drive shaft is important for the measurement of the starting torque. The first half of this article studies this relationship. The second half tells how to measure the starting torque of three different types of motors in five different ways. The result of the study shows that, if the relationship between the output torque and the micro-rotation of the drive shaft is taken into consideration, the measured value of the starting torque is independent of the measurement method.
