Abstract

PURPOSE: To make easy the detaching work for the mandrel, by eliminating the looseness inserting the shaft into the hole in the case of the taper fitting between the mandrel and sleeve, and by injecting the high pressure oil for relieving the taper fit, on purpose to drive the mandrel at the stably connected condition.
CONSTITUTION: The taper portion 8 is installed in the hollow shaft 5 supported by the driving casing 4 of the mandrel 1, in the down coiler for coiling the hot strip, and the internal spline 9 is installed at another end. The spline 10 is engaged with the internal spline 9, and the mandrel's taper portion 12, in whose taper portion 8 is installed the oil groove 11, is forcibly fitted to the hollow shaft 5. The screw ring 15 is screwed to the end of the bearing seat 14 on the side of the internal spline 9, and the halved stopper ring 16 obstructs the disengagement of the screw ring 15. At detaching the mandrel 1, the high pressure oil is injected to the oil groove 11 in the mandrel's taper portion 12 so as to expand the taper portion 8 and to form the oil film at its contact surface; hereby, the detaching work for the mandrel 1 is easily performed.
