[0024] The present invention will be further described in detail below with reference to the drawings.
[0025] The invention provides an ultrasonic detection method for judging the lubrication state of rolling bearings under actual working conditions, including the following steps:
[0026] (1) Selection, installation and adjustment of ultrasonic sensors
[0027] According to the type of the test bearing, the working environment and the speed range of the test, the ultrasonic sensor required for the test is selected. The main parameters include the center frequency of the ultrasonic sensor, the focusing diameter (the diameter of the straight probe is the wafer diameter), the focal length, and the The temperature range used and so on. Install the ultrasonic sensor on the bearing seat, adjust the ultrasonic sensor to a proper position through the adjustment device (electric or manual multi-degree-of-freedom adjustment platform, etc.), while ensuring good contact between the outer sur...
