Brake- and/or clamping device for shafts with a clamping ring

In a brake and clamping arrangement for a shaft (80) supported in a device housing (40), comprising

• a brake disc (10) supported rigidly on the shaft (80) for rotation therewith, the brake disc (10) having at least one friction area (31) with a truncated cone-shaped friction surface (32),
• and at least one brake cone (65, 45), which is arranged in the device housing (40) adjacent the friction surface (32, 47) and, during braking or clamping in engagement the friction surface (32, 47), wherein
• for a braking or clamping loading and for a vent unloading of the brake disc (10) said at least one brake cone (65, 45) is movable by either one of two actuating members one for movement in a loading and one for movement in an unloading direction or by a control member (60) for movement in one actuating direction and a spring system with at least one spring element (71) for movement in the other actuating direction, the improvement wherein
• in the device housing (40) a clamping ring (100) is non-rotatably arranged,
• the clamping ring (100) comprises a flange connecting area (111), an intermediate area (121) and a clamping area (131),
• the clamping area (131) is movable in axial direction (8) with respect to the flange connecting area (111) over the intermediate range (121) which is disposed next to the clamping area (131) and which is elastic,
• the clamping area (131) has an inner and an outer truncated cone shaped clamping surface (132, 133), and
• the inner clamping surface (132) is arranged opposite the friction surface (32) of the brake disc (10), whereas the outer clamping surface (133) is disposed in front of the friction surface (69) of the brake cone (65).
