DOUBLE-STAGE BELT-BLOCK BRAKE WITH THREE-LAYERED RUBBER-ROPE RING Russian patent published in 2006 - IPC F16D49/08 

FIELD: mechanical engineering.

SUBSTANCE: brake comprises braking pulley, braking belt, tree-layered rubber-rope ring with friction linings made on the working surface of the pulley, and drive. The friction linings are composed of two members that are in a longitudinal contact with each other. The friction linings are mounted on the rubber-rope ring whose central part is provided with the longitudinal ropes over periphery. The outer and inner cylindrical surfaces of the three-layered rubber-rope ring are provided with the dovetailed projections. The transverse ropes are molded in the bases of the dovetailed projections. The projections are provided with the friction linings whose inner working surfaces are fit with interference on the working surface of the braking pulley from the side of its detachable flange due to the flexibility of the three-layered rubber-rope ring.

EFFECT: enhanced reliability and efficiency.
