This paper presents a kind of online measuring system for the running flexibility of rolling bearing. The system detects the running flexibility by measuring the changing ratio of the rotation speed of the gear and realizes digital detection. Mechanical structure of this system includes the centering device, the loading mechanism, the rotary device and the speed measuring mechanism. It also can measure a variety of bearings. The active control operation was accomplished by the PLC, while the acquisition and processing program was developed based on LabVIEW. The changing ratio of rotation speed was obtained by the curve fitting method which can be used for the basis of digital detection of running flexibility. The experimental results show that the measurement accuracy of the system is reliable and it can realize the unmanned online detection of bearing flexibility, also it meets the requirements of the automatic measurement of running flexibil-ity in automatic assembly line of rolling bearing.
