FIELD: mechanical engineering; material testing. SUBSTANCE: friction unit has specimen and counterspecimen mounted on parallel shafts, each having cylindric disk and toothed wheel. Specimen and counterspecimen cylindric disk diameters are equal to initial circle diameters coaxially mounted together with the disks on the shafts of the toothed wheels. EFFECT: enhanced accuracy in testing material properties. 2 dwg
