Characteristic of cold rolling mills is their operation over an extremely large range of speeds reaching up to 2,000 m/min. That's why the main drive units often comprise change-speed gears with two transmission stages. This provides a correspondingly wide speed range. The spur gears and mill pinion gears are arranged in one housing.
You can use SMS group low-vibration gears to improve the end product quality produced by your existing cold rolling mills. Whether you choose new SMS group low-vibration gear boxes or change only the gear sets, you'll spot the difference right away!
Installing the new SMS group change-speed gear into your reversing cold mill means you can also operate the plant as a skin pass mill. During skin pass rolling, only one roll is driven. The other roll is disconnected from the drive train by a mechanism inside the new gear box.
