摘要： A finished toothed sprocket segment is forged in a cavity of a first die by a second die having a protrusion which extends into the cavity. The sprocket segment has first and second spaced datum pads formed on a first curved surface of a rim of the sprocket which locates the sprocket segment on a hub. The first and second datum pads and first and second apertures are located relative to each other so that distortion of the sprocket segment during final heat treatment does not effect the relative position. As a result the apertures in the hub and sprocket segment are easily aligned during attachment of the sprocket segment to the hub. Since the first die requires no draft angles, the critical surfaces on the sprocket segment are forged to final finish, flatness and tolerance.

摘要： 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.

摘要： A welded assembly has first and second portions connected one to the other by welds about a common axis. Testing apparatus holds one of the portions against rotation about the axis and controllably exerts a torquing force of a preselected magnitude on the other portion. The torquing force is exerted about the axis and oriented relative to the welds for exerting a radial force through each of said welds. Application of the torquing force and radial forces provides nondestructive testing of the welded assembly and of the welds of the assembly, respectively.
