AI Technical Summary
Existing bearing durability testing equipment is prone to causing runout due to eccentric rotation of the bearing during durability testing, which leads to unstable radial load applied by the testing equipment, affecting test accuracy and repeatability, and may also aggravate vibration and noise, or even damage the equipment.
A device comprising a support base, a housing, a mandrel, a loading structure, and a centering component was designed. The overall structure is stably assembled through the cooperation of the support base and the housing. The linkage between the loading structure and the adjustment structure enables the stable application and precise control of the radial load. The centering component counteracts the runout caused by the eccentric rotation of the test bearing, ensuring smooth operation of the mandrel.
It improves the accuracy and repeatability of test data, adapts to the special structural characteristics of eccentric needle roller bearings, provides reliable test support, ensures load stability and test reliability, reduces vibration and noise of the device, and extends the service life of the equipment.
