Abstract (en)
[origin: EP0169475A2] The cylinder has a shell (2) provided with a rubber coating (1) and a spindle (7) which penetrates said shell with clearance. The shell (2) is mounted rotatably in lateral bearing plates (5) independently of the spindle (7) and the ends of the spindle (7) project from the shell (2) and can be charged by respectively assigned actuators (11) to bring about a bending compensation. A long service life of the rubber coating (1) can be achieved even at high rotational speeds of the shell (2) in that the annular space (12) between the shell (2) and the spindle (7) is incorporated in a cooling circuit which passes over a cooling unit (13). For this purpose, the ends of the spindle (7) are enclosed in each case by a closure cap (14) which is penetrated by the actuator (11), is attached to the adjacent bearing plate (5) and is sealed off against the rotating shell (2) and which is provided with connections (15) for the forward branch (16) or return branch (17) of the coolant circuit. In order to guarantee a sufficient throughput of coolant through the annular space (12), a bypass line (20) is provided in each case in the region of the support bearings (8) arranged between the shell (2) and the spindle (7). <IMAGE>
