FIELD: mechanical engineering. SUBSTANCE: gear for implementation of procedure is made of body for placement of specimens which is put on carriage or table of machine. Tail part linking specimens is connected in this case to spindle of machine and is rotated. Specimens are weighed on optical balance before and after test to determine degree of wear resistance. Rings cut out of cylinders of blocks or shafts or tubes are used as specimens. Studies are conducted simultaneously with use of two specimens with different machining of surface securing soft and uniform touch of surfaces of specimens and surfaces of rings or inserts with the aid of spring-loaded casing. EFFECT: increased efficiency of studies. 4 cl, 3 dwg
