摘要
In a track chain running gear (2) for mining machines (1), in particular heading machines, having at least one running gear case (5) and a track chain which runs around the running gear case (5) and which is formed by a multiplicity of chain links (3) articulatedly connected to one another, that side of the running gear case (5) which faces towards the underlying surface has sliding plates (6) which form contact surfaces for the chain links (3) running along them, wherein the chain links (3), on their side facing towards the sliding plates (6), have wear plates (7), the projecting surfaces of which interact with the contact surfaces of the sliding plates (6). In a chain link (3) for a track chain running gear (2), the chain link (3), on its side facing towards the sliding plates (6) of the running gear case (5), has wear plates (7), the projecting surfaces of which interact with the contact surfaces of the sliding plates (6). In a method for producing chain links (3) of a track chain running gear (2), wear plates (7) are placed into a casting mould for the chain link (3), and the chain link (3) is subsequently produced by casting, wherein the wear plates (7) placed into the casting mould are cast around such that, after the casting process, the wear plates (7) project beyond the surface of the chain link (3).
