초록 ▼

An endless track chain with a rotatable bushing is disclosed that utilizes sleeve bearings for rotatably mounting the inboard end collars of the links about the pin. The joint of the track chain is sealed and lubricated. Sealing rings for the joint incorporates the use of a second set of seals for sealing between the rotatable bushing and the inboard end collars of the link. A unique design for the links enables the chain to accommodate the second set of seals without any loss of structural integrity in the chain or any disadvantageous increase in rail gauge width (\G”) of the chain. The track chain also utilizes a punch for mechanically interlocking the outboard end collars of the links to the end portions of the pin to eliminate joint end play.

In an endless track chain for track-type vehicles, said chain having a plurality of link sets articulately coupled in transverse relation to a longitudinal centerline of said cain by a like plurality of joints, each link set including a pair of laterally spaced, longitudinally extending links, each link having a laterally inwardly offset inboard end collar, an opposite laterally outwardly offset outboard end collar and a longitudinally disposed rail surface, said rail surface having a predetermined overall width (“W”) between an inner edge and an outer edge and a full width central portion, a generally half-width outboard portion extending along said outer edge over said outboard end collar and a generally half-width inboard portion extending along said inner edge over the inboard end collar, the improvement comprising: said inboard end collar having a first bore therethrough and extending from an inner surface of said inboard end collar to an outer surface thereof, said inner surface being offset inwardly from said inner edge of said rail surface and said outer surface being offset outwardly relative to said inboard portion of said rail surface so as to be disposed in a position substantially closer to said outer edge of said rail surface than to said inner edge thereof, said offset positioning of said inner and outer surfaces providing said first bore with a predetermined bore length (“L1”) that is greater than one-half the width (“W”) of said rail surface; and said outboard end collar having a boss extending outwardly therefrom and a second bore therethrough and extending from an inner surface of said outboard end collar to an outer surface on said boss, said inner surface being likewise offset outwardly from said inboard portion of said rail surface so as to lie outboard of the offset outer surface of the inboard end collar of a mating link in an adjoining link set of said track chain, and said outer surface on said boss being offset laterally a substantial distance from said outer edge of said rail surface to provide said second bore with a predetermined bore length (“L2”) that is at least as great as the overall width (“W”) of said rail surface.
