FIELD: test equipment. ^ SUBSTANCE: assembly is used for checking wear resistance of high-elastic materials, for example, rubbers, under conditions of modeling of shock of solid particle against surface of material at hydro- and gas-abrasive wear. Assembly has load unit. The latter has indenter's drive connecting rod gear disposed on slider and making reciprocal motion. Connecting rod of mechanism is made cut and has two parts, one of which ends with guide and the other one - with slider. Relative motion of both parts is restricted by spring. ^ EFFECT: permanent force of stroke. ^ 2 cl, 1 2 dwg
