(7.6)Improving reliability of mill drive gear boxes at New Bar Mill, Tata Steel

摘要

Gear Box is the heart of any mill drive and any outage can result in heavy loss as the down time cost in present day high production unit is very high. With advancement in Gear Design, Gear Boxes are getting smaller and smaller for a given horse power rating resulting in much more aggressive surface loading in the Gear Boxes. While this reduces frictional losses and improves efficiency, it tends to run hot, increasing the need for managing the lubricant more effectively.
