Abstract
A driving device for rolls in high speed rolling mills and the like, designed to effect the centering of a drive shaft element and of a driven shaft element and the transmission of torque. In a hollow space defined in a shaft assembly comprising two shaft members coupled together as by a spline connection for rotation as a unit, a spring is disposed which acts to axially extend the drive shaft. Either the inner bottom surface of a driven fitting yoke coupled to one end of the shaft assembly through a joint member and loosely fitted on the driven shaft element or the end surface of the driven shaft element is provided with a conical projection axially aligned with the fitting yoke and the driven shaft element while the other is provided with a conical opening adapted to tightly engage the conical projection, thereby achieving automatic axial alignment between the driven fitting yoke and the driven shaft element and eliminating the problem of the rotational vibration of the drive shaft.
