摘　　要：介绍了一种新型偏置式径向柱塞马达的结构特点。对该马达柱塞的排量、扭矩和运动特性进行理论分析,结果表明该马达具有低速启动性能好、滑靴滑移性能好、运行平稳、噪声低等特点,性能明显优于一般的低速大扭矩马达,且相对于其他类型的液压马达其寿命增加,加工和维修难度降低,除用于普通液压系统外,在一定条件下还可用于纯水液压系统。The structural features of a new type of offset radial piston motor was introduced. The displacement,torque and kinetic characteristic of the motor piston theory was analyzed,the results show that the motor has characteristics of good startup performance at low speed,good sliding performance with sliding boots,smooth operation,low noise and so on,so the performance is superior to the general motor of low speed and high torque,and compared with other types of hydraulic motor,its lifetime increases,it is also easier to produce and repair,except for the common hydraulic system,under certain conditions can also be used in pure water hydraulic system.
