本発明は、圧延条件に合わせて通常圧延かアイドル圧延
かを簡単に選択できて各種の圧延に対応できると共に、
圧延能率の向上をなし得られる圧延機の駆動装置に関す
るものである。DETAILED DESCRIPTION OF THE INVENTION The present invention allows for easy selection of normal rolling or idle rolling according to rolling conditions, and is compatible with various types of rolling.
The present invention relates to a driving device for a rolling mill that can improve rolling efficiency.
一般に金属の平板圧延において、１回の圧延で可能な圧
下量又は圧下率は、比較的板厚が厚い場合に圧延機の伝
達可能なトルクから制限され、又板厚が薄い場合には圧
延機の板形状制御が可能な圧延力で制限されている。In general, when rolling metal flat plates, the amount of reduction or reduction rate that can be achieved in one rolling is limited by the torque that can be transmitted by the rolling mill when the plate is relatively thick, and when the plate is thin, the rolling reduction The rolling force that allows control of the plate shape is limited.
現在、金属の平板圧延は、２本の上下ワークロールの間
を被圧延平板を通過させることにより行われている。Currently, metal flat plate rolling is performed by passing the flat plate to be rolled between two upper and lower work rolls.
この場合、上下ワークロールが等径であって等速で駆動

によれば圧延力は上下ワークロール駆動の場合（通常圧
延の場合）よりも低下するが、駆動トルクに関してはア
イドル圧延の駆動軸は上下ワ−クロール駆動の各駆動軸
に比べるとトルクが大になる。In this case, it is generally practiced that the upper and lower work rolls have the same diameter and are driven at a constant speed. At this time, the upper and lower work rolls may be driven and the upper and lower work rolls may be rotated by the frictional force acting between the upper work roll and the upper work roll or between the lower work roll and the lower work roll, respectively. Generally, the rolls have the same diameter and a constant speed. According to so-called idle rolling, which is rolling performed by rotating one of the upper and lower work rolls while driving the other without driving the other, the rolling force is lower than when the upper and lower work rolls are driven (normal rolling). Regarding the drive torque, the drive shaft for idle rolling has a larger torque than the drive shafts for driving the upper and lower work rolls.
従って両ワークロール駆動とアイドル圧延の特性を生か
し、例えば比較的厚物の圧延ではトルクが大のために両
ワークロール駆動とし又薄くなるにつれて圧延力が増加
するので、アイドル圧延を行うことが同じ圧延装置で簡
単に選択できれば圧延能率の向上を図り得る。Therefore, by taking advantage of the characteristics of both work roll drive and idle rolling, for example, when rolling a relatively thick material, both work rolls are driven because the torque is large, and as the thickness becomes thinner, the rolling force increases, so idle rolling is the same. If the rolling equipment can be easily selected, rolling efficiency can be improved.
しかしながら従来の圧延装置において両ワークロール駆

付けや取外し等によるためにこの切り換えに時間を要す
ることになって圧延スケジュールに応じ迅速に切り換え
を行うことができなかつた。However, in conventional rolling equipment, switching between driving both work rolls and idle rolling requires time due to the installation and removal of spindles, etc., making it difficult to switch quickly according to the rolling schedule. Ta.

れていた。Specifically, the rolling equipment is driven using a pinion drive system in which the work rolls are connected to a motor through a spindle and pinion stand, and a pinion drive system in which the upper and lower work rolls are driven independently without using a pinion stand. An individual drive system was adopted in which the motor was driven by a motor.

てなることを特徴とするものである。However, the former does not have a structure in which torque transmission can be easily interrupted between the work roll and the spindle or between the spindle and the pinion stand, and even in the pinion stand, one side of the pinion stand is closed halfway from the spindle side to the motor side. Since the spindle does not have a structure that can cut off the transmission of torque, it is not possible to easily switch from normal rolling to idle rolling. Since the structure is such that there is no torque transmission separation mechanism between the two work rolls, it is easy to drive only one of the upper and lower work rolls and rotate the drive shaft and motor from the other work roll via the spindle, just as in the former case described above. In reality, it was not possible to make the other one an idol. Furthermore, it is also not possible to transmit the torque of both motors to only one drive shaft. In view of these circumstances, the present invention relates to a rolling mill drive device that allows rolling by selecting normal rolling or idle rolling with a simple operation according to the capacity of the rolling mill and rolling work conditions. Two connected drive shafts are rotatably arranged in parallel, and a two-stage idling gear is provided on one drive shaft so as to be freely rotatable and connected to the other drive shaft via the gear, and a two-stage transmission gear is provided on one drive shaft. They are installed side by side on the outside of the idler gear, and a connecting shaft is rotatably arranged so that the gear faces the transmission gear and is located on its central axis, and the upper roll or the lower roll is attached to the connecting shaft, and the other roll is attached to the connecting shaft. The drive shaft is characterized by connecting the lower roll or the upper roll to the drive shaft, and further comprising a connecting mechanism that connects the gear of the connecting shaft and the transmission gear, or the transmission gear and the two-stage idling gear. It is.

For example, without being limited to the examples, it is possible to connect the motor and the drive shaft by a chain sprocket, or to drive a backing roll instead of a work roll, etc., and various modifications may be made without departing from the gist of the present invention. Of course, other changes may be made.
