Abstract:
A connection between a spindle head of a gear spindle or universal joint spindle and a neck of a roll, comprising wear plates placed between torque-transmitting locating surfaces of the spindle head and the roll neck so as to form a positively engaging connection, the spindle head comprising a clamping device for applying pressure to the wear plates and for clamping the spindle head onto the roll neck, wherein the clamping device is mounted such that a clamping force of the clamping device results in a play-free frictionally engaging connection between the spindle and the roll neck, wherein the clamping device comprises at least one bolt resting in a frictionally engaging manner against the wear plates, and a piston of a hydraulic tensioning cylinder for applying pressure to the bolt, further comprising a locking screw received in a housing of the tensioning cylinder for securing the piston, further comprising a cup spring bundle for acting with restoring force on the bolt and the piston of the tensioning cylinder, further comprising a pressure-distribution plate placed underneath the bolt at an end thereof facing the wear plate, a solid disk surrounding a head of the bolt, and a tensioning nut for holding the solid disk against a restoring force of a cup spring bundle mounted between the disk and the pressure distribution plate.
