Abstract
A combi roll that comprises a roll shaft having a rotationally symmetrical basic shape defined by a central axis, as well as a number of rings in the form of roll rings and spacer rings, each one of which has planar end surfaces that extend between outer and inner, circular limiting edgelines, and that serve as contact surfaces against adjacent rings. At least one of the end surfaces of a ring, preferably a spacer ring, is limited by an inner edgeline, the diameter of which is greater than the outer diameter of the roll shaft. In such a way, the area of the contact surface is reduced while increasing the surface pressure, at the same time as the force transmitting ability of the surface increases by the fact that the radial distance to the center axis is increased.
Claims4
A roll, comprising
- a roll shaft having a rotationally symmetrical basic shape that is defined by a center axis;
- a plurality of rings mounted on the roll shaft, each one of said rings having two planar end surfaces extending between outer and inner, circular limiting edges, and serving as friction contact surfaces for the transmission of torque to adjacent rings;
- wherein two opposite end surfaces of the rings are both limited by inner edges, diameters of which are greater than an outer diameter of the roll shaft;
- said opposite end surfaces included in a spacer ring, one of said opposite end surfaces being urged against an end surface of a roll ring, the roll ring having an inner diameter equal to the outer diameter of the roll shaft.
