This test rig consists of rigidly mounted test roller (cylinder) pressed against a friction wheel which is in cross-cylinder contact configuration. The friction wheel is partially submerged in the lubricant bath under test. In this test, rig loading is applied through dead weights. Normal load and frictional force are measured through dual measurement load cell. A contact type acoustic emission detector is incorporated for scratching noise from the contact. The lubricant chamber contains a heater and controls lubricant temperature from ambient to set value. Online data acquisition software acquires the normal load, frictional force, coefficient of friction, sound level, temperature of the oil bath, and sliding distance and analyzes & compares the test. In addition, Koehler will provide an optical microscope with CCD camera-based image acquisition system software to measure wear scar area, which is done by measuring the major axis and minor axis of the scar for calculation of scar diameter.
