加工特别精密的半成品,有时液压扇形支座主轴在温度作用下,其旋转精度和刚度不能令人满意,会改变直线尺寸和容积尺寸。这时不可避免的改变了主轴支承的间隙,无论主轴部件旋转精度,还是刚度均表现不良。考虑到这点,乌克兰苏梅市物理工艺研究所研制了带主动控制间隙系统的液压扇形支座,允许扶持它在最佳间隙,结果达到提高了主轴旋转精度和主轴部件刚度之目的。 Machined particularly sophisticated semi-finished products, and sometimes hydraulic fan bearing spindle temperature, the rotation accuracy and stiffness are unsatisfactory, will change the linear size and volume size. This inevitably changed the gap between the spindle support, regardless of the accuracy of the rotation of the spindle components, or stiffness are poor performance. With this in mind, the Institute of Physical Process Technology in Samui, Ukraine, developed a hydraulic fan-shaped support with an actively controlled clearance system that allows it to be held at optimum clearance with the result of improved spindle rotation accuracy and spindle component rigidity.
