摘　　要：为降低轴承在轴承转子系统中的振动,课题组提出了一套基于气动控制的自适应预紧加载装置。以预紧力和转速为判断依据,研究了在不同转速下,预紧力对转子和轴承滚动体的抑振效果;开发了由数据采集系统以及气动系统组成的主动控制系统,实时监测轴承在转动过程中的振动状态,并适时调整预紧力,确保轴承正常运行时最大程度地抑制振动;通过对装有调心滚子轴承(22208CA)的转子系统进行实验测试,验证该装备的抑振作用。实验结果表明:在转子转速小于一阶临界转速时,该装置有30%以上的抑振效果,轴承振动幅度大大降低。相较于现有的智能轴承单元,该装置为转子轴承系统抑振提供了更高效、简便的解决方案。In order to reduce the vibration of bearings in the bearing rotor system,a set of adaptive preload device based on pneumatic control was proposed.The vibration suppression effect of preload on the rotor and bearing roller at different rotating speed was studied based on preload force and rotating speed.An active control system composed of data acquisition system and pneumatic system was developed to monitor the vibration state of the bearing in the process of rotation in real time,and the preload was adjusted timely to ensure that the vibration was suppressed to the greatest extent during the normal operation of the bearing.The rotor system equipped with an aligning roller bearing(22208CA)was tested to verify the function of the device.The experimental results showthat the vibration suppression effect of the device is more than 30%when the rotor speed is less than the first critical speed,and the bearing vibration amplitude is greatly reduced.Compared with the existing intelligent bearing units,the device provides a more efficient and simple solution for vibration suppression of the rotor bearing system.
