Rotary tribometer (RT8001 and TRM 1001)
|
A rotary tribometer is used to investigate and simulate friction and wear processes under continuous or oscillating sliding stress and axial load. With the aid of suitable adapters, almost all test specimen geometries can be used on these universal tribometers. In addition, tests with original components, such as axial plain bearings, valves, pump running surfaces, etc., are also possible. |
|
The factors that are decisive for tribological behavior, such as friction partners, surface roughness, normal force, sliding speed, temperature, sliding distance, surface pressure, intermediate material and ambient medium can be varied and controlled within wide limits on these test rigs. All measurement data is stored on a PC and is then available for further processing. |
| TRM 1001: The normal force of up to 1 kN is usually applied to the TRM1001 by means of a pneumatic muscle and can be varied in the barrel. However, it is also possible to statically load the specimen with a lever system. The drive is provided by a highly dynamic servo motor. |
| RT 8001: The RT8001 rotary tribometer is an in-house development for higher normal forces up to 8 kN. The normal force is applied pneumatically on the RT8001. The drive is provided by a state-of-the-art servo motor. With the aid of a special torsion adapter, static friction processes can also be resolved with high precision. |

The rotary tribometer is used to investigate and simulate friction and wear processes under continuous or oscillating sliding loads in solid, boundary and mixed friction as well as in elastohydrodynamics. With the aid of suitable adapters, almost all test specimen geometries can be used on these universal tribometers. In addition, tests with original components, such as thrust bearings, valves, etc., are also possible. |
