多作用双定子力偶液压马达转矩脉动分析

提出了力偶液压马达,在阐述多作用双定子力偶液压马达工作原理的基础上,探讨了多作用双定子力偶液压马达的理论转矩,深入分析了多作用双定子力偶液压马达的脉动特性及滚柱连杆数对其的影响,得出滚柱连杆数与转矩脉动之间的数学关系,滚柱连杆数小于等于8时,滚柱连杆数为偶数的液压马达产生的转矩脉动程度优于滚柱连杆数为奇数时的脉动程度;而滚柱连杆数大于等于9时,滚柱连杆数为奇数的液压马达产生的转矩脉动程度优于滚柱连杆数为偶数时的脉动程度。

Analysis of Torque Pulsation for Multi-acting Double-stators Couple Hydraulic Motor

The concept of the couple hydraulic motor is put forward, which is different from the traditional hydraulic motor. Based on the principle of the multi-acting double-stators couple hydraulic motor, the theoretical torque is studied. Through analyzing the pulsating characterize and the influencing factors of the motor, the relationship between the pulsation and the numbers of sliders is obtained. When the number of the rollers and connecting rods equals to 8 or less, the torque pulsation of the hydraulic motor consisted of the even number of the rollers and connecting rods is lower than what number is odd. When the number of the rollers and connecting rods equals to 9 or more, the torque pulsation of the hydraulic motor consisted of the odd number of the rollers and connecting rods is lower than what number is even. Finally, a theoretical basis is provided for the design and experiment of the hydraulic motor.
