Abstract
A reel for winding metal strip, in particular rolled hot strip, having a mandrel shaft (2), which has a first shaft end piece (18), which is rotably mounted by means of at least one bearing (4) provided in the machine frame (3) of the reel, a clamping device (5) arranged between the at least one bearing (4) and the mandrel shaft (2), such that, in a clamped operating state, a frictional connection can be produced between the at least one bearing (4) and the mandrel shaft (2).
Claims9
A reel for winding metal strip and hot-rolled strip comprising:
- a machine frame;
- at least one bearing in the machine frame;
- a mandrel shaft having a first shaft end piece which is rotatably mounted by the at least one bearing in the machine frame;
- and
- a clamping device disposed between the at least one bearing and the mandrel shaft, the clamping device being configured and operable such that in a clamped operating state thereof, the clamping device produces a tangential frictional connection between the at least one bearing and the mandrel shaft,
- wherein the clamping device is configured to be actuated hydraulically to produce the tangential frictional connection between the at least one bearing and the mandrel shaft.
