What is it?
The Reichert friction and wear tester consists of a rigidly-mounted test roll, which presses against a revolving friction wheel by means of a weighted lever. The friction wheel is semi immersed in the test fluid. Its rotating speed is of such a rate that a sufficient quantity of lubricant is always in the contact area between the test roll and the friction wheel.
Why do we use it?
This machine is widely used within the lubricant industry due to the availability of numerous test methods and metallic components.
How does it work?
Due to the crosswise arrangement of the axles, an elliptical wearing surface is formed, the size of which grows as a function of operating time.
The extension of the wearing surface results in a decrease of the absolute pressure between friction wheel and test roll and we would normally expect a load-carrying lubricant film to be built-up in the contact zone.
This effect can be recognised by a sudden discontinuation of the grinding noise apparent when we first start the tests. The size of the wear scar gives a rating for the fluid under examination
