The STD-TE 47 Three Station Ring/Liner Tribometer allows three idealised piston ring samples to be run against an unmodified cylinder liner. The key difference between this device and more conventional reciprocating tribometers is that instead of running up and down the liner, the samples are run around the internal circumference of the liner in either continuous rotation, allowing high sliding speeds to be achieved, or oscillating motion.
A complete (unmodified) cylinder liner sample is attached by means of an expanding collet to the test spindle. The lower end of the liner sample is supported by a steady bearing carried on a secondary cross-head. A spline shaft assembly, which mounts on the main cross-head, carries a ring sample carousel. The carousel is free to slide axially on, while its rotation is resisted by, the spline.
