摘要:
The invention relates to a disc-packet unit (1) comprising a pre-tensioned disc packet (2) for mounting on guide elements in a transmission component. Said packet comprises at least two adjacent elements (4.1) that form frictional surfaces, which can be intercoupled in a frictional engagement by means of an intermediate element (5.1) that forms a frictional surface and comprises an auxiliary mounting device (3). Said packet comprises at least one spring device (6.1) located between at least two adjacent elements that form frictional surfaces. The auxiliary mounting device comprises at least one sleeve element (7) and a tensioning device (9). The elements (4) that form frictional surfaces are carried on the sleeve element (7) and the latter comprises a stop (8). The tensioning device (9) can be detachably connected to the sleeve element (7) and produces a force for pre-tensioning the disc packet, in such a way that friction is generated between the elements that form frictional surfaces (4.1) and the intermediate elements (5.1).

The present invention relates to a wear compensating device for a shoe brake having a brake lever (2, 4), which brake lever (2, 4) supports a brake lining (12) which acts on a brake body (14), and which brake lever (2, 4) is adjustable by means of an actuating arrangement (16) about a main axis (7) between a braking position and a ventilating position. Here, the wear compensating device has a first adjusting device (100) which is arranged on the brake lever (2, 4) and which acts on a stop (18) in such a way that the latter, as an actuating travel delimitation, acts on the first adjusting device (100) and therefore at the same time on the brake lever (2, 4) and defines a corresponding ventilating position. The first adjusting device (100) has an adjusting element (102) which engages on the stop (18) and on which acts an adjusting force (126) which, during braking and ventilation of the brake (18), holds the adjusting element (102) in engagement with the stop (18) and varies the ventilating position of the brake lever (2, 4) corresponding to the wear of the brake lining (12) and/or of the brake body (14) in such a way that a ventilation gap (L) which is set between the brake lining (12) and brake body (14) remains constant. The invention also relates to a brake device having two brake levers (2, 4) which has a wear compensating device of said type.

A disk brake device comprises a brake lever (3A) toward which a tilting force is applied in opening operation. This brake lever (3A) is formed at its lower end with an outwardly protruding stopper (58) into which an adjusting bolt (56) is screwed vertically. A base seat (59) is provided on a base plate (1) immediately under the stopper (58). A pinion (61) is fitted over an upper end of the adjusting bolt (56) via a one-way clutch (60) so as to rotate the adjusting bolt (56) only in a direction of fasting the same downward. A rack (67), which is supported by the base plate (1), is meshed with the pinion (61) to have a predetermined backlash and to extend in a direction of swing of the brake levers (3A,3B). This disk brake device allows to assuredly maintain the brake levers (3A,3B) at equally opened positions at left and right in a brake releasing condition, even if brake linings (9A,9B) are worn out and adjustment is made by an automatic lining wear adjusting unit (53) to automatically decrease the gap caused by wear of the brake linings (9A,9B).

Yaw brakes for wind turbines are proposed, the wind turbines having a tower, a nacelle and a yaw system for rotating the nacelle with respect to the tower. The yaw brakes comprise a locking part, having a toothed profile at a side facing a toothed profile of an annular gear of the yaw system. The locking part of the yaw brakes is movable in a radial direction relative to the annular gear, between a brake position and a non-brake position. Brake discs and callipers may be eliminated.
