Abstract

DC60 (26/08/45) This invention concerns a drive system (1) for a particular cold piler roller, which has at least one oscillating roller (2), at least one crank mechanism (3) fitted with a crank arm (4) with a balancing weight (5) that at least partially neutralizes the inertia generated by the roller (2), a drive unit (6) and a connecting rod (7) which connects the roller (2) to the crank arm (4) in a segmented manner, and at least one rotating balancing weight (8, 9) arranged with its center offset from the axis of rotation to counteract the inertia and/or moment of inertia, in order to achieve effective neutralization of the moment of inertia of the simple drive system. This invention provides for at least one balancing weight (8,9) which is driven by separate, independent drive units (10, 11). From the drive unit (6) for the crank mechanism (3), this invention concerns the drive system (1) for a particular cold piler roller, which has at least one oscillating roller (2), at least one crank mechanism (3) fitted with a crank arm (4) with a balancing weight (5) that at least partially neutralizes the inertia generated by the roller (2), the drive unit (6) and the connecting rod (7) which connect the roller (2) to the crank arm (4) in a segmented manner, and at least one rotating balancing weight (8,9) arranged with its center offset from the axis of rotation for the inertia side and/or moment of inertia to achieve effective neutralization of the moment of inertia of the simple drive system. This invention provides for at least one balancing weight (8,9) which is driven by a separate drive unit (10,11) independent of the drive unit (6) for the crank mechanism (3).

Claims (13)

1. The drive system (1) for a rolling machine, especially a cold piler rolling machine, consists of - at least one movable rolling table (2), - at least one crank mechanism (3) which has a crank arm (4) with an opposing weight (5) suited to compensate at least partially for the inertia created by the rolling table (2), a drive unit (6) and a connecting rod (7) for connecting the rolling table (2) and the crank arm (4) in a segmented manner, and - at least one opposing weight (8,9) which is mounted in such a way that it rotates eccentrically suited to compensate for the inertia and/or moment of inertia, with the special characteristic that one or more opposing weights (8,9) can be driven in a rotational manner by separate drive units (10,11) which act independently of the drive unit (6) of the crank mechanism (3). 2. The drive system under claim 1, which is characterized by an independent drive unit (10,11) for driving an opposing weight (8,9) that can rotate in the opposite direction to the rotation of the crank arm (4). 3. A drive system according to claim 1 or 2, which is characterized by the selection of the mass of the rolling stock (2), the opposing weight (5), and one or more opposing weights (8,9) such that the inertia of the first-order rolling stock is at least largely offset during the operation of the drive system (1). 4. A propulsion system according to one of the claims 1 through 3 which is characterized by two sets of opposing weights (8, 8' 9, 9') arranged in order in the form of a mirror image described with respect to the central plane of the propulsion system (1). 5. Any of the drive systems under claims 1 through 4, which have the special characteristic that a balance shaft (13,14) for adjusting the opposing weights (8,9) is arranged at the end of the crankshaft said to be in the same direction of rotation and at the same height as the actual crankshaft. 6. The drive system according to claim 5 is characterized by the balance shaft (13,14) being driven by means of a cylindrical gear set consisting of a pinion gear on the motor shaft, which drives a toothed gear on the crankshaft with a specific gear ratio, as well as a toothed gear of the same size which is arranged on the balance shaft (13,14) and meshes with the toothed gear on the crankshaft. 7. Any of the propulsion systems under claims 1 through 6, which are characterized by separate propulsion units (10,11) made up of electric motors. 8. The drive system under claim 7, which is characterized by an electric motor composed of servo motors. 9. A drive system under any of the claims 1 to 5 and 7 or 8 which is of the special nature that the path (12) is arranged for the control or determination of separate drive units (10,11) that are independent on the angle of rotation (chemical formula) and/or speed of rotation (chemical formula) of the drive unit (6) of the crank arm (4). 10. The drive system according to claim 9 is characterized by the fact that the path (12) is optimized for the operation of the drive unit (6) of the crank arm (4) and the separate drive units (10,11) with the same rotational speed (chemical formula, chemical formula, chemical formula). 11. The drive system according to claims 9 to 10 is characterized by the fact that the path (12) is optimized for the correct phase-match operation of the drive unit (6) of the crank arm (4) and of the separate drive units (10,11). 12. The drive system according to claims 9, 10 or which is of the special nature that the path (12) is made suitable for the operation of the drive unit (6) of the crank arm (4) and the separate drive units (10,11) with the speed of rotation and the angle of rotation. 13. Any of the drive systems under claims 1 through 12 is of the nature that the center of rotation (chemical formula, chemical formula, chemical formula, chemical formula) of the opposing weights (8, 9) is chosen in such a way that when introduced into the list of inertial forces of the rolling mill (2) and/or the opposing weights (5), the moment of inertia of the total mass of the drive system (1) is offset by at least a large extent.
