ABSTRACT:
A drivable roll of controllable flexure, particularly for machines for the production and processing of paper or plastic webs. The roll comprises a cylindrical inner part (1) which through journals is firmly supported on bearing surfaces (5), and a tubular outer part (3) which is rotatably supported on the inner part (1). On the inner part (1) there are disposed along a generatrix means for the generation of compulsive forces acting radially between the inner part and the outer part. A drive shaft (6) which extends coaxially through the journal (2) and which is supported on the journal and on the inner part is integral with a center gear (10) which through an idler gear (11) drives an internal ring gear (14) that is secured to the outer part (3) through clamping means (15a, 15b). The axis of rotation (Z) of the idler gear (11) is parallel to the drive shaft (6), and its teeth (11a) have a crest which arcuately slopes downwardly on either side in the direction of the axis of rotation (Z). The drive can be implemented readily and at low cost. The roll will withstand high loads even with small-diameter journals, and deflections of the outer part will not interfere with the operation of the drive.
