提出了一种用于金刚石车床的水驱动主轴。主轴利用水流通过水驱动电机驱动转子，通过水静压轴承支撑转子，以及作为冷却剂。由于水是不可压缩的清洁流体，而且是低粘度流体，因此可以在清洁的环境中实现高速精确的旋转运动，以实现超精密加工。本文介绍了主轴的结构和工作原理。本文推导了用于主轴设计的理论方程。对主轴特性进行了理论和实验研究。
A water drive spindle for diamond turning machines is proposed. The spindle uses water flow for driving the rotor by a water drive motor, for supporting the rotor by water hydrostatic bearings, as well as for coolant. As water is not only incompressible and clean but also low viscosity fluid, it is considered that a high-speed and precise rotational motion will achieve in the clean environments for ultra-precision machinings. The present paper reports a structure of the spindle as well as the operational principle of the spindle. In the present paper, theoretical equations used for designing the spindle is derived. The characteristics of the spindle are studied theoretically and experimentally.
