摘要： A wind turbine comprising a number of wind turbine blades extending substantially radially from a hub on a main shaft having a substantially horizontal axis is described. The wind turbine blades together with the hub form a rotor, which can be put into rotation by wind. The main shaft is rotatable mounted in a nacelle that is mounted on top of a tower, and the nacelle may be rotated around a vertical axis in relation to the tower so as to adjust the rotor in relation to a prevailing wind direction. The wind turbine further comprises a yaw brake comprising a brake calliper and a brake disc or ring having a first side with a first surface and second side with a second surface, the yaw brake, when activated, acting as a rotation restriction of the nacelle in relation to the tower. The brake disc or brake ring is provided with one or more grooves formed in the first surface and/or the second surface.

摘要： The present invention relates inter alia to a hydraulic braking system. The braking system is particularly well suited for deployment in wind turbine constructions and is well suited for other constructions as well. The braking system comprises a hydraulic brake calliper (1) with a hydraulic brake piston (5) and a disc (7); the brake piston is moveable in a direction normal to surface of the brake disc to force a brake pad (11) against the surface of the disc. The brake calliper further comprises two elements (2a, 2b) protruding from a base element (3) and straddling a segment of the brake disc with a gap size there between being larger than the thickness of the disc, fastening means (6) provided in the base element for fastening the calliper to a construction, and a ledge (4). The ledge is provided in the gap between the two protruding elements at the base element, has a radial and circumferential extension relatively to the orientation of the brake disc and proceeds in between the brake piston and the fastening means to define a minimum gap size in between the two elements.

摘要： The brake or coupling system (1) comprises a first piston (2) arranged in a first piston cylinder (3) thereby forming a first piston chamber (5) and a second piston (8) arranged in a second piston cylinder (9) thereby forming a second piston chamber (10). The first piston (2) is adapted to be displaced between a braking position and a rest position. The first piston (2) is spring biased in the direction of its rest position, and the second piston (8) is adapted to adjust a distance (X) provided between a friction element (6) and a rotatable element (7) in the rest position of the first piston (2) by means of adjustment of a volume of hydraulic fluid trapped in the second piston chamber (10). At least one spring element is arranged to act between the first and second pistons (2, 8). The first and second pistons (2, 8) are so arranged that a hydraulic pressure in the first and second piston chambers (5, 10), respectively, will urge the first and second pistons (2, 8) in opposite directions, thereby biasing the at least one spring element.
