More Information
Summary:The invention relates to a releasable coupling hub for a working roll of a series of rolls, which coupling hub has an accommodating geometry for a roll journal arranged coaxially on the working roll in order to transfer a torque from a drive to the working roll. The connection of the roll journal in the accommodating geometry is preferably designed as a form and/or force closure. According to the invention, means (10) for lubricating contact surfaces (11) between the roll journal (5) and the accommodating geometry (6) of the coupling hub (1) are provided inside the coupling hub (1). Such a means (10) comprises a lubricant reservoir (12), which could be actuated at least indirectly by means of the roll journal (5).
