摘要： An improved method and apparatus are provided for sealing hollow pins which are commonly used as lubricant reservoirs in, e.g., track chain assemblies of crawler tractors, and linkage joints of earthmoving vehicles. One embodiment of the invention comprises a plug of elastomer material which has a lubricant passage axially therethrough, which passage receives an auxiliary plug means for the purpose of obturating the passage as well as causing radial expansion of the elastomer plug into positive engagement with a receiving axial bore in a hollow pin. The auxiliary expansion means takes the form of a screw, a spherical ball, or a headless plug employing a plurality of annular serrations. Another embodiment comprises a spherical ball which is received in a stepped, axial bore of a hollow pin and is retained therein by a Belleville washer. The invention facilitates refilling in the field of the lubricant reservoir contained within the pin.

摘要： A method and apparatus for rapidly and efficiently welding track hinge joints wherein the assembled track hinge joint is supported in a suitable fixture and welding guns are supported for movement in a circular path approximating the circumference of a track pin which is to be secured at its ends to respective track links. Additional means initially align the welding guns with the track pins, operation of the welding guns being regulated by suitable control means. The welding method and apparatus described above may also be employed for rebuilding endless track including a plurality of track hinge joints. Additional power units are employed to initially remove the track pin from the track hinge joint in order to prepare the track links for welding in subsequent reassembly as described above.

摘要： A resilient spacer means, such as a pneumatic rubber tire, has an endless track assembly mounted thereon. The track assembly comprises an annular and articulated link assembly positioned on each side of the spacer means to closely couple a plurality of ground engaging track shoes together. Each track shoe has a ground engaging grouser secured thereto to be disposed parallel relative to the rotational axis of the cushioned track. A cross grouser is attached to each shoe to extend substantially perpendicularly relative to the first-mentioned grouser to resist lateral sliding movement of the cushioned track during operation thereof.
