TE 76 TWO STATION RECIPROCATING VACUUM TRIBOMETER

 





  •  

     

    Description

    The TE 76 is a two-station, vertical axis, long stroke reciprocating tribometer, which combines the reciprocating drive mechanism and fixed specimen mounting from the TE 77 High Frequency Friction Machine with a UHV test chamber.

    The test assembly is located vertically above the reciprocating drive assembly and comprises two fixed specimen pads, each mounted on flexures, with movement in the friction direction resisted by piezo-electric force transducers. The pads have fluid passages allowing the samples to be heated or cooled by circulation of a heat transfer medium.

    The fixed specimen assemblies are mounted on vacuum rated linear slide bearings allowing horizontal freedom of movement. Load is applied to either side of the moving specimens by squeezing the two fixed specimen assemblies together, by means of a servo controlled pneumatic bellows, with force transducer feedback. This arrangement ensures that there is no bending moment acting on the moving specimen arm.

    Feed-throughs for load application and reciprocating motion are sealed with edge-welded stainless steel bellows, thus eliminating any requirement for sliding seals.
