DEVICE FOR PERFORMING FRICTION TESTS ON MATERIALS Russian patent published in 2006 - IPC G01N19/02 G01N3/56 

FIELD: engineering of equipment for friction tests.

SUBSTANCE: as sample holder a shaft is used, which is connected by means of connecting rod mechanism to swinging movement drive, made with possible setting of shaft rotation angle and its rotation speed during rotation for given angle. On top of sample a counter-sample is mounted with its own holder. Sample loading unit abuts by rollers on counter-sample holder. Measuring system includes forces indicator, connected to counter-sample holder, sample movement indicator, connected to its holder, indicator of load output, connected to samples loading unit, optical-mechanical indicators, each one of which is made in form of disk with slits pinned onto axis of arrow of appropriate indicator between emitter and photo-detector, and is connected to computer through mouse port.

EFFECT: increased trustworthiness and precision of tribological characteristics of round and spherical bodies during rotation thereof.
