Purpose The PV friction tester adopts the form of sliding friction, which can be tested under the conditions of oil-free lubrication or oil-immersed lubrication and changing load, speed, time, friction partner material, surface roughness and hardness of the friction pair. It is mainly used to evaluate the applicable range of plastic, powder metallurgy, alloy and other bearing materials, and to determine the reasonable fit clearance and PV value of bearings.
Technical Parameters 1. Maximum test force: 20KN 2. Test force accuracy: ± 1% 3. Spindle speed: 300-2800r / min, infinitely adjustable 4. Speed control accuracy: ± 10r / min 5. Maximum friction torque: 40Nm 6. Relative error of friction torque: ± 3% 7. Temperature range: room temperature ~ 300 ° C 8. Measurement error: ± 2 ° C 9. The computer controls the whole test process, which can collect test data in real time, display various test parameters, and in the same time coordinates, using four color curve: load - time, friction coefficient - time, temperature - time, linear velocity - time, through the printer to print the test curve and report.
