Title:
WINDING DEVICE
Document Type and Number:
Japanese Patent JP3310640
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To increase a critical speed so as to increase a maximum speed of rotation by decreasing deflection of a winding shaft.
SOLUTION: In a winding device, a winding shaft 1 which is capable of being assembled into and removed from the winding device is provided with a winding tube 10 and a journal 11a protruding in a direction of a center line MA of the winding shaft 1 at both ends. The winding device has two outer bearings 2 which accommodate the journal 11a for pivotally supporting the winding shaft 1, and auxiliary bearings for the winding shaft 1 additionally provided respectively to the outer bearings 2 in a spaced relation with each other. The outer bearing 2 is provided with a jointing mechanism. The jointing mechanism is capable of sliding along the center line MA of the winding shaft 1, and being jointed to or released from the end of the journal 11a. The auxiliary bearing is provided as an inner bearing 3 on the journal 11a of the winding shaft 1 between the end of journal 11a capable of jointing to the outer bearing 2 and the winding tube 10.
