Abstract

A brake system (10) for a rotating component (12), the brake system including a plurality of discs (14) coupled to said component (12) to rotate with said component (12) about an axis, each disc (14) having first and second opposite radial surfaces (22a, 22b), and a plurality of brake plates (16) fixed against rotation but linearly movable relative to said discs (14) parallel to said axis, each brake plate (16) having a braking surface (20). The discs (14) and brake plate (16) juxtaposed so that at least one of the radial surfaces (22) of each disc (14) is facing the braking surface (20) of a brake plate (16). At least one of the facing braking surface (20) and the radial surface (22) is provided with a plurality of grooves (24, 26). The grooves (24, 26) orientated to provide fluid flow paths across at least one of said facing braking surface (20) and radial surface (22). An actuator axially moves the brake plate (16) relative to the discs (14) between an engaged position where braking surface (20) is in engagement with a facing radial surface (22) and a disengaged position where said braking surface (20) is spaced from said facing radial surface (22). A sealed housing is provided …
