The Wazau tribometer serves for the investigation and simulation of friction and wear processes under sliding conditions. It can be operated for solid state friction without lubrication and for boundary lubrication with liquid lubricants. Thus both material

and lubricant tests can be executed.

 

According to the standard test principle a stationary test specimen (pin or disc) with a defined normal force is pressed against the surface of a rotary disc. Both specimens are perpendicularly arranged one on the other whereby the rotary disc is on top. Other test configurations are possible. The normal force is applied by the movable drive block and the drive spindle. The normal force is damped by means of a spring located below the linear table. The tribometer is driven by a servo motor steplessly adjustable from 0.1 rpm to 3000 rpm.

The actual test equipment essentially consists of the motor unit, the drive and the load section. The shiftable modules are one on the other fastened to two perpendicularly columns. Pin and disc are in a specimen pot heatable up to approx. 150

¡ãC. During the test the normal force, the temperature inside the pot, the linear wear amount of both specimens and the

friction torque are continuously measured.

 

The measurement of the normal force is done by a force sensor arranged between counter load spring and lower specimen restraint. The temperature is measured by a NiCr-Ni-thermocouple in the pot. The wear is measured over the changing displacement between lower and upper specimen restraint. The measurement is done contactlessly by a laser-optical displacement sensor. The friction torque is measured by a rotary torque sensor. 

 

All measuring signals are transferred to the control rack to be conditioned there. Data acquisition is done by an USB measuring module with a solution of 16 bit. The measured values of rotational speed and temperature are digitally monitored with temperature values sampled at 2 Hz and rotational speed sampled at 5 Hz.
