MULTI-PIECE PART FROM DRIVABLE SUPPORT SHAFT AND ROLLER ROLLER EXISTING ON THIS REPLACEABLE ROLLING RING

摘要

The arbor is formed by two annular collars 1, 2 which, with their front sides facing each other, can each be placed on one of the two front sides of the roll-ring 10. Connected to one of the annular collars 2 is an axial clamping device 7, 14a which is passed centrally, with radial clearance, through the other annular collar 1 and acts on the latter at the front side facing away from the roll- ring 10. Those front sides of the annular collars 1, 2 which face the roll-ring 10 here have a plurality of annular bearing faces 1f, 1g, which extend outwards with a different inclination with respect to the radial of the centre line and can be placed on corresponding mating faces on the front sides of the roll-ring 10. The number and inclination of these annular bearing faces 1f, 1g, their distance from the centre line and the size of the bearing pressure exerted by the clamping device 14a on these faces are dimensioned in such a way that the tensile bending stresses to be expected during the operation of the roll, which occur at their outer periphery, are considerably reduced by this pressure.
