摘要： Joint assemblies are useful for connecting one structure to another structure. When the various structures deflect or bend, edge loading occurs therebetween. The subject joint assembly includes a pin positioned between a first and second structure. An insert is free floating positioned around the pin for contacting either of the first or second structures. A crown shaped surface is utilized on the insert at a substantially central location therealong. The crown shaped surface directs forces to the center of the insert to reduce edge loading.

摘要： A method and apparatus of assembling a joint of an endless track chain for track-type machines to prevent end play in the joint is disclosed. The joint includes a pair of links and a cylindrical pin. Each link includes a outwardly offset outboard end collar having a boss extending outwardly therefrom and a bore therethrough. Each boss has an outer surface. The pin includes opposite end portions. Each end portion is pressed and non-rotatably mounted into respective one of the bores of the outboard end collars. The method comprises the steps of forming an annular groove about each of the end portions, placing a swage tool against the outer side surface of the boss in axial alignment with the pin, and applying a sufficient force on the swage tool to form at least one mechanically formed nodule protruding from the outer side surface into a respective ones of the grooves. The nodule having a cross-sectional configuration substantially conforming to the groove.

摘要： An endless track chain is provided with a rotatable sleeve that is mounted about the track bushing to provide the track with longer external bushing life. The rotatable sleeve is sealed and lubricated, as is the standard track joint. However, each is separate from the other with its own supply of lubricant. As a consequence, a failure of a seal for the rotatable sleeve has no effect on the track hinge joint.

摘要： A track adjusting flow controlling mechanism sets the optimum tension or "controlled sag" in the endless track of a track type vehicle. A piston and associated valve assembly control flow of pressurized fluid to a track adjusting clyinder. Movement of the piston tensions the track with substantially no sag ("S") and subsequent retraction of the piston provides correct track tension with an optimum track sag ("S"). Supply of pressurized fluid to the piston and valve assembly is controlled by the vehicle operator from the operator's station. Conventional track adjusting operations require considerable time and effort and are often an undesirable task. In view of this, the adjusting task is often neglected with the resulting rapid wear of the track and related components. The subject track adjusting mechanism provides a quick and simple operation to provide proper track adjustment.

摘要： A drive sprocket assembly for driving an endless chain assembly for propelling a vehicle includes a housing, which is mountable to the power drive system of the vehicle, and a plurality of replaceable teeth structures which are secured to the housing. The housing includes a hub portion having a cushion band and spaced apart parallel flanges. Each tooth structure is in contact with the hub and is secured to the flanges by a plurality of retaining pins. Each tooth structure is resiliently isolated from the hub by the cushion band and from adjoining teeth structures by non-metallic pads. Conventional drive sprocket assemblies utilize a one-piece toothed sprocket, or sprocket segments having several teeth, bolted to a support member. These prior sprocket assemblies produce considerable noise from impacting of the sprocket teeth with an endless chain assembly. The subject sprocket assembly produces low levels of noise by utilizing individually replaceable teeth structures which are resiliently isolated from the support housing and from adjoining teeth structures.

摘要翻译： 用于驱动用于推进车辆的环形链组件的驱动链轮组件包括可安装到车辆的动力驱动系统的壳体和固定到壳体的多个可更换的齿结构。 壳体包括具有缓冲带和间隔开的平行凸缘的毂部分。 每个齿结构与轮毂接触并通过多个保持销固定到凸缘上。 每个齿结构通过缓冲带和相邻的齿结构通过非金属垫片与轮毂弹性隔离。 传统的驱动链轮组件使用一体式齿形链轮或具有多个齿的链轮段，螺栓连接到支撑构件。 这些现有的链轮组件产生相当大的噪音，从而与环形链组件碰撞链轮齿。 本发明的链轮组件通过利用与支撑壳体和邻接的齿结构弹性隔离的单独可更换的齿结构来产生低水平的噪音。
