BELT-BLOCK BRAKE WITH ACOUSTICAL COOLING

摘要

FIELD: mechanical engineering. SUBSTANCE: space of the pulley is provided with a cooling device made up as radial cylinders arranged in two mutually perpendicular spaces and clamped in the body of the pulley. Plates are mounted on flexible supports inside the radial cylinders. The plates are mounted with a spaced relation to each other. Pistons that are various in length almost abut against the plates. The rods are coupled with an electric motor that provides reciprocation of the rods. The space of a radial cylinder is filled with helium. EFFECT: decreased heat stress in friction pairs. 2 cl, 3 dwg
