摘要：

介绍了一种新型的凸轮转子连续回转电液伺服叶片马达的工作原理及特点.通过对叶片的系统受力分析，得出马达干扰力矩产生的机理.通过计算机仿真得到了马达的凸轮正压力以及干扰力矩与减压压力的变化规律.干扰力矩会造成马达的速率波动，选择马达斜坡信号跟踪下的误差曲线的误差带作为衡量马达速率波动的指标，对不同减压压力下的误差带进行对比.结果表明，随着减压压力的增加，马达的速率波动也越加剧.

关键词: 凸轮转子, 叶片马达, 干扰力矩, 速率波动

Abstract:

A novel continuous revolving electro-hydraulic servo cam-rotor motor was introduced with its operating principle and features. The mechanism of the disturbing torque of the existing motor was found based on systematical force analysis of the vanes. The rules of positive pressure of the motor’s cam and disturbing torque with changes of oil pressure from the reducing valve were obtained by computer simulation. As disturbing torque would cause the speed fluctuation of the motor, the error band of the error curve of motor’s ramp signal tracking was chosen as the indicator of the scale of motor’s speed fluctuation. The comparisons of error band at different oil pressure from the reducing valve demonstrated that the speed ripple of the motor was more intensified with the increase of the reduced pressure.

Key words: cam-rotor, vane motor, disturbing torque, speed fluctuation
