【Abstract】 In order to monitor the important status information of high-speed spherical bearing under high-speed oscillating condition,such as applied load,wear status,vibration and noise,temperature variation,friction torque, and etc,an oscillating characteristic inspection system for spherical bearing was developed. In the system,an IPC is used as the host computer,and PLC is served as the salve computer. The system control software is developed on the software platform LabVIEW. An adjustable dynamic balance mechanical transmission device is adopted to simulate the oscillating working condition. An electro-hydraulic closed-loop servo control loading system is used to simulate different kinds of applied loads. Various sensors are used to monitor the status information of the spherical bearing; and a high-speed multi-channel analog signal acquisition card is used to collect the status information in real time. The test system can contribute to determining the high-speed spherical bearing performance characteristic indexes and optimizing the structure dimension parameters. In the meantime,the system also can be used as a mean for evaluating the quality of high-speed spherical bearing.更多还原
