摘要

只提供摘要形式。主轴是高速数控机床中最重要的部件。主轴的驱动系统和支承系统决定了主轴的热动态特性。高速主轴必须满足某些特殊要求;c轴控制也是必需的。研制了一种内置电机驱动的高速大功率主轴。无框主轴电机位于轴承之间。无框电机由空气-水冷却系统冷却。采用Si/sub 3/N/sub 4/陶瓷球轴承支撑主轴。采用油-气润滑器来减小摩擦力和控制温升。讨论了改善机床性能的一些设计问题。

Design of intelligent spindle for high speed machining

Summary form only given. The spindle is the most important component in a high speed CNC machine tool. Its thermal and dynamic behaviors are almost decided by the drive system and the support system of the spindle. Some special requirements for high speed spindles must be satisfied; C-axis control is also required. A high speed, high power spindle driven by a built-in motor has been developed. The frameless spindle motor is located between the bearings. The frameless motor is cooled by an air-water cooling system. Si/sub 3/N/sub 4/ ceramic ball bearings are used to support the spindle. An oil-air lubricator is used to reduce the friction force and control the temperature-rise. Some design problems are discussed for improving the behaviour of the machine tool.
