③径向柱塞马达柱塞组相对于传动轴成径向布置的液压元件称为径向柱塞马达(视其工作情况定义为马达)。如图8所示,径向柱塞马达能在很低的转速下稳定可靠地工作,可以和需要低速运转的工作机构直接相连,使整机结构简化,还具有效率高和使用寿命较长的优点,故而近年来有 ③ radial piston motor plunger group relative to the drive shaft radial arrangement of hydraulic components known as the radial piston motor (depending on the definition of its work as a motor). As shown in Figure 8, the radial piston motor can work stably and reliably at a very low speed and can be directly connected with the working mechanism that needs low speed operation, which simplifies the structure of the whole machine and has the advantages of high efficiency and long service life Advantages, so in recent years there
