Claims

[Scope of utility model registration request]

a driven-side fitting yoke that is provided at one end of a coupling connected to the drive shaft and has a fitting hole with a substantially oval cross section and parallel flat surfaces into which a roll neck of a rolling roll is fitted; A cross shaft that rotatably connects the shaft provided in the center of the coupling ring and the driven-side fitting yoke, and a housing that is integrated with each of the shaft and the driven-side fitting yoke and supports the cross shaft. and a spacer disposed between the shaft, the driven side fitting yoke, and the housing to prevent the driven side fitting yoke from hanging when the rolling roll is pulled out. ,
A rolling roll driving device characterized in that the flat surface of the fitting hole of the driven side fitting yoke and the axis of the cross shaft are shifted in phase by approximately 45 degrees.
