CLUTCH-BRAKE Russian patent published in 2005 - IPC

FIELD: mechanical engineering; mechanical presses and other forging machines.

SUBSTANCE: proposed clutch-brake has hub with channels to feed air into space of sectional pneumatic cylinder rigidly secured on hub and including ribbed cover, movable piston sealed by cups, brake support disk, U-shaped movable pressure and intermediate driven disks, ribbed cover plate of clutch, driving friction disks of clutch and brake, brake springs and adjusting washers. Novelty is that sectional pneumatic cylinder is made in form of ribbed cover rigidly coupled by screws with L-shaped ribbed shell forming its cylindrical side surface being support disk of brake. Pins with threaded adjusting bushing with locknuts are uniformly spaced over circumference of brake support disk interacting through brake spring installed on pins with end face surface of U-shaped pressure disk of clutch-brake. Piston is movably installed through cup seals on hub in inner space of L-shaped ribbed shell of sectional pneumatic cylinder between ribbed cover and end face of L-shaped ribbed shell and it interacts with pressure driven disk of clutch-brake through ring with through holes made over circumference rigidly secured on piston.

EFFECT: improved reliability and increased brake torque of clutch-brake and service life of engagement unit.
