金属切削机床电液传动的调节范围,在低速时工作的稳定性以及在全部调节范围内的旋转均匀性都取决于液压马达及其操纵装置和电液放大器。本文以表格的形式列出了国外主要液压公司生产的一些液压马达的特性。最广泛使用的是轴向柱塞油马达,约占70％。较少使用的是径向柱塞油马达,约占15％;而滚柱叶片油马达使用得更少,约占10％。据统计表明,它们最宽的转速范围为0.1～2000转/分。从目前的各公司资料统计,尚没有一种油马达在各种性能指标上都是首屈一指的。因此要按自己的具体情况来进行选择。在径向柱塞油马达方
The adjustment range of the electro-hydraulic drive of the metal cutting machine, the stability of the work at low speed and the uniformity of the rotation over the entire range of the adjustment depend on the hydraulic motor and its controls as well as the electro-hydraulic amplifier. This article lists in tabular form the characteristics of some hydraulic motors produced by major foreign hydraulic companies. The most widely used is the axial piston oil motor, accounting for about 70%. Less is the use of radial piston oil motor, accounting for about 15%; while the roller blade oil motor used less, about 10%. According to statistics, their widest speed range of 0.1 ~ 2000 rev / min. Statistics from the current company statistics, there is no one oil motor in a variety of performance indicators are second to none. Therefore, according to their own specific circumstances to choose. Radial piston oil motor side
