摘要： A track roller assembly for use in crawler-type tractors including a shaft adapted to be secured to the track frame of the tractor and a hub journalled on the shaft. The hub has opposite ends externally threaded for receipt of internally threaded retaining caps. The caps engage and locate guide flanges on the hub and, in addition, include inwardly directed surfaces directed toward oppositely facing annular shoulders on the shaft. Thrust bearings are received between the shoulders and the surfaces and radially inner and outer annular seals are disposed about the surfaces to sealingly engage the shaft and the hub respectively.

摘要： A noise attenuating system for the tracks of a track-laying vehicle. A plurality of noise attenuating devices are disposed about the track chain of a track-laying vehicle, one device mounted upon each track shoe. Each device is comprised of a preloaded spring means in the form of a block or pad of elastomeric material and each device is mounted upon the inner circumferential portion of an individual track shoe. A wear plate means is included for directly engaging the radially outermost portions of the teeth of the driving sprocket of the track-laying vehicle. The devices are disposed so that the outermost edges of the sprocket teeth engage the wear plates prior to engagement of the track bushings with the sprocket notches and are also disposed so that metal-on-metal contact between the leading and trailing edges of each respective link shoe is preceeded by contact between each respective leading edge and the elastomeric material from which the spring means are composed.
