Title:
ロールとそれのためのスペーサーリング
Document Type and Number:
Japanese Patent JP5117688
Kind Code:
B2
Abstract:
In a first aspect, the invention relates to a combi roll of the type that comprises a roll shaft (1) having a rotationally symmetrical basic shape defined by a central axis (C), as well as a number of rings in the form of roll rings (2) and spacer rings (3), each one of which has planar end surfaces (12, 15) 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 edge-line, 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 centre axis is increased. In another aspect, the invention also relates to a spacer ring as such.
