DEVICE FOR FRICTION AND WEAR TESTING OF MATERIALS Russian patent published in 1997 - IPC

FIELD: testing engineering. SUBSTANCE: device has base 1, holder 2 of counter-specimen 3 connected with drive 4 of rotation of counter-specimen 3, force meter that consists of holder 5 of specimen 6 and ring 7. Ring 7 is provided with strain gauges 9 for measuring forces applied to a specimen. The device also has unit 10 for control of a constant normal load applied to specimen 6 and counter-specimen 3. The output of unit 10 is connected with the input of loading device 11 made up as reciprocation actuator 11 and its input is connected with the outputs of strain gauges 9. EFFECT: improved design. 4 dwg
