Accessoriess
The main components of a sliding bearing PV friction testing machine include the headstock, tailstock, tool holder, torque sensor, force sensor, spindle assembly, loading system, linear guide rails, air bellows, and motor.
Test Procedures
Sample Preparation: Load the sliding bearing sample to be tested onto the test rig, ensuring its surface is clean and smooth.
Load Application: Apply a specific force or pressure to the sample surface using the loading system, simulating the load conditions under real working conditions.
Start of Test: Start the test machine control system, controlling the movement speed and load changes of the test rig according to preset conditions, and begin simulating the friction and wear process.
Data Acquisition and Analysis: Collect and record data such as friction force, load changes, and sample surface morphology in real time, and perform analysis and comparison to evaluate the friction performance and wear resistance of the sliding bearing.
