AI Technical Summary
Existing bearing sealing testing devices cannot accurately detect the gap between the inner balls and the outer ring of the bearing when the bearing is stationary during the testing process, resulting in inaccurate test results.
A rotary motor is installed on the bearing sealing test device. The motor drives the transmission shaft to rotate via a telescopic rod, which in turn drives the inner ring of the bearing to rotate. Combined with a wind pressure sensor and a wireless signal transmission structure, the test data is uploaded in real time.
This technology enables real-time detection of bearings under simulated working conditions, improving the accuracy of detection results, timely detection of the gap between the inner and outer rings of the bearing, simplifying the operation process, and reducing detection costs.
