TE 88P Three Station Pin on Disc Machine is designed for wear testing of materials under high contact pressures in pin on disc configuration, in accordance with ASTM G99.
The machine is bench-mounted and includes a 2.2 kW variable speed a.c. vector motor and three pin on disc test stations.
A heated non-rotating fluid enclosure is provided with each test station allowing tests to be performed in fluid environments with a temperature limit of 200°C. A lid is provided to minimise fluid splashing. A thermocouple is fitted to the lower part of the enclosure to monitor and control the temperature.
Each test station has a load/friction/wear assembly. A loading beam is pivoted at one end and a pneumatic bellows is used to apply a load at the other end. A force transducer mounted on the bellows allows the applied load to be measured. Load is adjusted by means of a manually set precision regulator.
The load beam pivot is trunnion mounted and restrained from movement, when in the horizontal position, by pads mounted on the load application bracket. A strain gauge force transducer mounts on the load beam and fits between these pads when the arm is horizontal thus allowing the friction signal to be sensed.
An LVDT is mounted in contact with the underside of the load beam. As the pin wears, the vertical movement of the load beam is detected by the transducer. Wear of up to 1.5 mm at the contact can be measured.
Control and Data Acquisition
Control and data acquisition are implemented via host PC running COMPEND 2020 Windows compatible software, in conjunction with a Phoenix Tribology USB micro-controller interface.
Automatic control is implemented via user programmable test sequences. Manual control is implemented using on screen toggles. Data is stored to hard disc in either .csv or .tsv file formats.
