Abstract

487,759. Rolling. KRUPP GRUSONWERK AKT.-GES., F. Jan. 26, 1938, Nos. 2534 and 2535. Convention dates, Feb. 10, 1937 and June 30, 1937. [Class 83 (iv)] Four support rollers 3, 4, 7, 8, are provided for each working roll 1 of a rolling mill and the centres of the contacting rollers, e.g. 3, 7 and the roll 1 all lie on the lines of pressure in straight lines. Pass adjustment is provided by rotating the eccentric rings 13, Fig. 2 (not shown), of all four outer rollers 8 &c. by worm drives either individually or by hand or coupled together and driven by electric motor and worms and through chain and clutch for the bottom outer support rollers. The bearing blocks 25, 26 of the upper and lower large rollers are held in position in the frames by cross beams 32, 33 which may be swung out on an end hinge pin 37, Fig. 4 (not shown), to facilitate removal. The small support rollers 3, 4 &c. are mounted in top and bottom bearing blocks 41, 45 which are vertically displaceable in recesses in the large blocks 25, 26 while the working rolls 1, 2 are held by straps 50, 51 urged vertically by springs 52 into recesses in the blocks 41, 45. Hydraulic rams 29 urge apart the bearing blocks 25, 26 and hold the top block 25 against the screw downs 30 and the bottom against distance pieces 56 resting on the base. The whole roll and support roller unit and their bearing blocks can be traversed bodily out of the roll frame, on wheels 53 on racks 54 when hydraulic or electric lifters 55 allow removal of the distance pieces 56 and so permit the wheels to be lowered on their racks.
