日本庆应义塾大学的稻崎一郎等教授设计的超高速主轴部件中,设置了压电元件和畸变仪(如图)。当滚珠经过畸变仪所在位置时,畸变仪根据轴承外圈的振幅,可得知轴承的松紧程度,并将信息反馈给控制系统,使压电无伴伸长或缩短,从而得到与转速适应的轴承松紧程度。自动调节轴承预紧量?
In Japan’s Keio University, Professor Ichiro Takasaki and other professors designed ultra-high-speed spindle components, set the piezoelectric element and distortion instrument (Figure). When the ball passes through the position of the aberration meter, the distortion meter can know the degree of tightness of the bearing according to the amplitude of the outer ring of the bearing, and feed the information back to the control system so that the piezo-electric partner can not extend or shorten so as to obtain the speed- Bearing tightness. Automatic adjustment of bearing preload?
