AI Technical Summary
Existing sliding bearing lubrication friction testing machines can only perform friction tests at a fixed swing angle for bushings of specific specifications. They cannot meet the testing requirements of multi-point and multi-model bearings in excavator working devices. Furthermore, they are difficult to modify, have poor compatibility, and cannot meet the testing needs of multiple machine models.
A friction and wear testing device suitable for multiple specifications of bearing seats was designed, including a test platform, an assembled fixture, a crank connecting rod mechanism and a hydraulic cylinder loading system. Through the movable inner and outer bearing bases, self-aligning roller bearings and hydraulic cylinder loading system, it can adapt to bearing seats of different lengths and specifications, and realize friction and wear testing of multiple specifications of bearing seats.
It enables friction and wear tests on bearings of different tonnages and specifications, provides test data support, supports fault analysis and reproduction of bearings of multiple specifications, and provides testing capabilities.
