ABSTRACT:
A variable length light weight drive shaft for a rolling mill roll including: a driven first end including a universal joint connecting with an end of a male splined shaft having an axial bore and counter bore and a driving second end including a universal joint connecting with a torque tube and a female spline shaft which engages over the male splined shaft for axial movement. A gas cylinder is mounted in the counter bore adjacent to the second end of the male splined shaft. A cylinder rod extends from the cylinder and is connected to with the universal joint at the driving end. The piston rod includes a self aligning coupler. The gas cylinder and cylinder rod exert continuous outward pressure against the driven and driving ends which maintains them in pressure contact with the driving and driven members while allowing axial movement of the drive shaft. The self-aligning coupler relieves stress on the drive shaft and particularly the cylinder rod by maintaining it axially aligned during movements of the drive shaft which are slightly off center.
