A device for wear test comprises a base, rotary drive, cylindrical body on the inner surface of which guides of counter-specimen holders are fixed, those are arranged as solids of revolution and placed in circle, concentrically with respect to the rotor, and rotary drive of the body. The rotor has slots for axles on which specimens are installed, those are arranged as solids of revolution. The body is arranged with possibility of rotation with respect to the axle. Rotary drive of the body is arranged as a toothed gearing made of three toothed wheels. One of those is installed on the shaft that transfers rotation from the drive to the rotor, the other one – with internal engagement, is fixed on the body, and the third is installed between the two first ones with possibility of rotation with respect to axle fixed on the base. The holders of the counter-specimens are arranged rotatably with respect to the axis of cylindrical guides that additionally include position retainers. |
