- Abstract
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 show that 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.
