AI Technical Summary
During use, existing axle bearings are prone to contact between the valve plates and brushes and the balls, which can lead to obstructed movement or wear. In addition, the lubrication system may fail due to impurities or prolonged use, affecting the normal use of the bearings.
A noise sensor is used to monitor the bearing operating noise in real time. When the control system detects abnormal noise, it starts the oil pump and supplies oil to the balls through the oil supply pipe and the oil outlet pipe. Combined with the design of the docking component and the fixed component, it is easy to maintain and clean.
This achieves efficient operation of the lubrication system, reduces obstruction and wear of the ball bearings, extends bearing life, lowers the failure rate, and simplifies the maintenance process.
