Abstract
A ring, preferably in the form of a lock nut, made for combi rolls, which ring includes at least one spring device in which a mechanical compression spring is included that acts between, on one hand, a front press body that is movable to and fro in order to constantly forward a spring force generated by the compression spring and, on the other hand, a support body, which may assume a fixed position, but which is adjustably movable by way of a screw in order to alter the tension in the compression spring.
Claims11
A roll comprising:
- a drivable roll shaft;
- two axially spaced-apart stop rings, one of the stop rings is fixed, and the other of the stop rings is a lock nut;
- and
- a plurality of other rings, one or more of said other rings being mounted on the shaft between the stop rings;
- wherein at least one of said stop rings comprises a spring device housed in a through hole extending axially and opening in opposite end surfaces of the at least one of said stop rings, said spring device comprising a mechanical compression spring acting between a front press body that is movable through an opening of said hole in order to constantly pass on a spring force generated by the compression spring to one or more of said other rings and a support body, wherein said support body during operation of the roll assumes a fixed position in relation to the at least one of the stop rings, said support body being adjustable when not in operation by way of an adjusting member to alter the stress on the compression spring, wherein the press body is a pin having a flange against which the compression spring is urged for placing a portion of the press body into compression;
- wherein a rear end of the press body is inserted in a seat in a front side of the support body.
3 more elements
A ring for a roll, comprising:
- a spring device housed in a through hole extending axially and opening into opposite end surfaces of the ring;
- said spring device comprising a mechanical compression spring acting between a front press body that is movable through an opening of said hole in order to constantly pass on a spring force generated by the compression spring and a support body which during operation assumes a fixed position in relation to the ring, but which is adjustably movable by way of an adjusting member in order to alter the stress on the compression spring, wherein the press body is a pin having a flange against which the compression spring is urged for placing a portion of the press body into compression;
- wherein a rear end of the press body is inserted in a seat in a front side of the support body.
