CLUTCH-BRAKE Russian patent published in 2006 - IPC F16D67/04 B30B15/12 F16D13/75 F16D65/46 

FIELD: mechanical engineering.

SUBSTANCE: clutch-brake comprises braking springs (27) mounted in sleeves (28) of the driven pressing disk of the unit for engaging clutch-brake (29) and in the adjustable sleeves (30) of the driven bearing finned disk for engaging clutch-brake (24) of the clutch. The clutch-brake is locked by means of splines (31). Movable intermediate combined disk (34) of the clutch is mounted for permitting free movement in axial direction over the ring surface of cylindrical part (35) of the threaded sleeves which projects out of the driven bearing finned disk of the unit for engaging clutch-brake (24) of the clutch. The bearing disk of the brake comprises bearing disk of brake (10) that is rigidly connected to the face of movable rim (11) by means of screws. The movable rim is connected with the unmovable rim of L-shaped air cylinder (4) by means of threaded connection (9). The cylinder receives piston (7) of the clutch-brake. The projecting part of the left side of the surface of piston (7) is provided with radial through grooves (33) that receive bottoms (32) of all sleeves (28) of braking springs (27) of driven pressing disk for engaging clutch-brake (29) for permitting movement. The face of ring part of piston (7) is in a permanent contact with the side of the driven pressing disk of the unit for engaging clutch-brake (29) of the engaging unit. The face of threaded rim (11) of the bearing disk of brake (10) of the brake is provided with through radial grooves. Two diametrically opposite grooves receive rectangular slides (13) for permitting reciprocation. The slide can lock rim (11) after adjustment.

EFFECT: improved design.
