Abstract
A cuffing chain for cutting mineral and metal materials has central chain links and lateral connecting links. The cutting chain has connecting pins with a central section which has a diameter that is greater than the diameter of openings in adjacent connecting links. The cutting chain has two connecting links which have a supporting section instead of a cutting element. At least two second connecting links positioned adjacent to one another at right angles to the direction of travel of the cutting chain are formed separately from one another. As a result, the cutting chain can be opened for maintenance and repairs despite the use of collar studs as connecting pins.
Claims17
A cutting chain for cutting mineral and metal materials, the cutting chain comprising:
- central chain links;
- lateral connecting links connecting the central chain links to each other, wherein at least two connecting links are positioned adjacent to each another, respectively, in a transverse direction relative to a direction of travel of the cutting chain;
- connecting pins connecting the central chain links to the connecting links;
- the connecting pins projecting through first openings in the connecting links and through second openings in the central chain links;
- the connecting pins each having a central axis, wherein the central axes of the connecting pins are lying in a common central axis plane when the cutting chain is extended;
- the connecting links including at least one first connecting link having a cutting element fixed thereto, the cutting element having a top facing away from the connecting pin;
- the connecting links including at least one second connecting link having a supporting section instead of a cutting element;
- the connecting pins each having a central section positioned between adjacent connecting links, wherein a diameter of the central section of the connecting pins is larger than the diameter of the first opening;
- and
- at least two second connecting links positioned adjacent to one another in the transverse direction relative to the direction of travel are configured separate from each other.
