MACHINE TO TEST MATERIALS FOR FRICTION AND WEAR Russian patent published in 1997 - IPC

FIELD: testing of materials. SUBSTANCE: bed frame 3 of machine carries holder 7 of tested sample 2 to which rotation drive is coupled kinematically. Holder 9 of sample 1 connected to loading mechanism 11 and vessel 17 for submersion of sample 1 and tested sample 2 into it are also mounted on bed frame 3. Loading mechanism is fabricated in the form of lever 10. Collet is anchored on one end of lever 10 with the aid of resilient plate 12 mounted for bending under action of frictional force which is used as sensor measuring frictional forces. Weight 11 is suspended from other end of lever 10. Sample 1 is made in the form of rod having diameter 3.0-5.0 mm. EFFECT: simplified design of machine, improved authenticity of test. 3 dwg
