ABSTRACT:
A brake assembly (10) for selectively starting and stopping rotation of a shaft (12) journaled in a frame (14) of a motor comprises an end plate (16) mounted to the motor frame, the end plate (16) being formed with mounting slots (40) formed axially therein. Friction discs (26, 26a) are secured to the shaft (12) for rotation therewith about the longitudinal axis of the shaft (12) and pressure plates (36, 36a, 36b) are non-rotatably mounted in the mounting slots (40) of the end plates (16) and axially movable toward and away from the friction discs (26, 26a). Separator springs (124) are slidably mounted around a peripheral portion of the pressure plates (36, 36a) mounted in the mounting slots (40) for urging the pressure plates (36, 36a) away from the friction discs (26, 26a) to minimize brake drag caused by contact of the pressure plates (36, 36a, 36b) and the friction discs (26, 26a) during rotation of the shaft (12), and for suppressing noise and wear caused by contact of the pressure plates (36, 36a) relative to the end plate (16) during brake operation.
