液压同步多马达与传统同步马达的对比分析

为研究新型液压同步多马达（筒称液压多马达）的同步特点，并分析其同步性能，把液压多马达用作同步马达应用在同步回路中，设计液压多马达的同步回路；对新型多马达同步回路和传统同步马达同步回路所实现的功能进行对比分析，并通过液压多马达的自身结构来研究影响其容积效率的因素；利用已加工出的液压多马达样机，组成三液压缸同步液压系统并进行实验，验证液压多马达驱动多缸同步回路的同步性能.理论分析和实验结果表明：新型液压多马达同步回路能够完全实现传统同步马达同步回路的功能，并且马达使用数量少，能够实现不同缸径液压缸同步，同步精度高（1.0%~1.7%).
To study the characteristics and synchronous performance of new hydraulic synchronous multi-motor (Referred to as hydraulic multi-motor), the hydraulic multi-motor is used as synchronous motor in synchronous circuit. The functions of new synchronous circuit and traditional synchronous circuit are compared and ana1yzed, and based on the hydraulic multi-motor structure, the factors affecting on its volume efficiency are studied. The three hydraulic cylinder synchronous system constituted by hydraulic multi-motor prototype is composed to carry out the experiments, and the synchronous performance is verified. Theoretical analysis and experimental results show that the new hydraulic multi-motor not only can completely realize the function of traditional synchronous motor with fewer components and higher precision (1.0%-1.7%), but also can achieve different diameter cylinder synchronization.
