PURPOSE:To enable the follow up to not only the vertical movement but also the horizontal movement with mill spindles by specifying the coupling of pins in the end parts on the output shaft side of a support frame provided with bearings for supporting the mill spindles. CONSTITUTION:A support frame 15 encloses both sides of a mill spindle 14 which connects the work roll 2 (the same holds true of 2') of a rolling mill and an output shaft 11 by means of universal joints 12, 13. A bearing 16 which supports the approximate centroid position of the spindle 14 freely axially movably and rotatably is provided to the frame 15. A ring 22 is provided on the outside circumference of the joint 12 apart from the same concentrically with a spindle 14, and is coupled freely rotatably by means of a pair of pins 23 to one end part of the frame 15 on the horizontal line X running the center of the joint 12. A pair of pins 24 are provided on the vertical line Y running the center of the joint 12 at the ring 22 and is mounted freely rotatably to the bearing part 25 fixed to the support base 17 of the shaft 11. On the other hand, the end on the roll 2 side of the frame 15 is coupled to the cylinder 20 on a stand or foundation by means of a pin joint 26 and a pin joint contg. a self-aligning bearing, and the cylinder 20 is tiltable horizontally. |
