Comparison Of Rolling Mill Drive Shaft Concepts

Universal joint shafts and slipper spindles are commonly used in rolling mills to compensate the design- and process-related offset between the motors and work rolls. Although both types of shafts exhibit on the same kinematic principle, there are basic differences regarding the design concepts. These differences become noticeable on many levels and may become very distinct in terms of Life-Cycle-Costs (LCC). In this respect, a critical comparison between universal joint shafts and slipper spindles can be made.
