Abstract: A track link for a ground-engaging track system includes a link body having a pin bore formed in a first link strap and a bushing bore formed in a second link strap. The link body includes, upon an outboard link side, a bore peripheral surface extending circumferentially around a bore center axis, and a guide protrusion including an outer bump surface located outboard of the bore peripheral surface. The pin bore receives a track pin attached by swaging and defines a diametric plane through the bore center axis oriented parallel to an upper rail surface. At least a majority of the outer bump surface is between the diametric plane and the upper rail surface, and an entirety of the outer bump surface may be between the bore center axis and the upper rail surface. The guide protrusion protects material of the track link and/or track pin from wear that can prevent re-swaging.

Abstract: A motorized chain roller includes a frame, a roller chain assembly movably disposed within the frame, a first sprocket that engages the roller chain assembly to apply a transmission force to the roller chain assembly, at least one motor coupled to the frame and configured to transmit a rotational force to the first sprocket, and a load-bearing member coupled to and located within the frame. The roller chain assembly includes a plurality of interconnected cylindrical rolls arranged in a continuous series. Each of the cylindrical rolls has an axis or rotation. The roller chain assembly engages the load-bearing member to cause movement between the roller chain assembly and the load-bearing member perpendicular to the axes of rotation.

Abstract: Track shoe assembly for a tracked vehicle, comprising a) a track shoe member with a chassis assembly having a pair of tubular housings (80) connected by a spaced web-portion, b) a replaceable rubber pad (9) with a curved sheet metal (13) having rims to hold the rubber pad rigidly and precisely in position, and c) an end connector (26) having a pair of bush holes (267) which accept an end of a track shoe pin (60) extending through a tubular housing, thus connecting adjacent track shoe members at either side in a pivotally flexible track. The chassis (9) also has a guide member (91) which is located on one a sleeve holding a housing and has a shape tapering towards its top end.

Abstract: In a track with a rotatable bushing which is brought into engagement with a sprocket of a track-type vehicle, it is intended that strength is enhanced rationally by link functionality sharing and by combination of such assigned functional tasks for achieving further improvements in rotatable bushing function. To this end, a first bolt insertion hole provided in a track shoe mount surface of an external link and a second bolt insertion hole provided in a track shoe mount surface of an internal link are arranged on the same straight line, and a straight line connecting the first bolt insertion hole and the second bolt insertion hole is situated at a position more interior than a contact plane of the external link and internal link.

Abstract: 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.

Abstract: A track for in-line tires on a skid steer vehicle, the track includes a continuous loop of links with sidebars and a pin and a barrel, the pin and barrel together forming a hinge between the links and extending between the sidebars. Tire side guides extend upward from the side bars to guide the tires along a pathway over the upward side of the hinges. The opposite side of the hinges engage the ground. The tire side guides can be permanently attached or temporarily fastened to the sidebars at selected positions and moved to other selected positions to convert the track for use with different sized tires, thereby proving a convertible track and a method of converting a track. A system for forming and closing the track as a loop of links is also disclosed.

Abstract: A guide for a multi-link endless chain of a track-type undercarriage, especially for cranes, has an undercarriage support, at least one drive sprocket wheel provided with chain teeth, possibly an idler, and several track rollers. Each chain link of the endless chain has two guide webs which are symmetric to the center, spaced a certain distance apart, and extend in the travel direction. The webs have engaging surfaces which ride on opposed circumferential flanges on the drive sprocket wheel. A cog connects the two webs below the engaging surfaces and meshes with the chain teeth of the drive sprocket wheel. The guide has two parallel rails oriented in the travel direction of the endless chain, the inside surfaces of the rails coming to rest against the outside surfaces of the associated guide webs when the guide function is occurring.

Abstract: Joint assemblies are useful for connecting one structure to another structure. When the various components deflect or bend edge loading occurs between the various components. The subject joint assembly includes a bushing positioned in one structure and a pin positioned in a second structure. An insert has an inner diameter positioned around the pin and an outer surface diameter positioned to interact with the bushing. The outer surface being a crowned surface. The joint assembly having the crowned insert directs forces to the center of the insert to reduce edge loading and deflection of the pin will be followed by the insert.

Abstract: A link for a track chain assembly of a track type work machine includes a body member having (i) a first side, (ii) a second side, (iii) a first aperture defined therethrough, and (iv) a second aperture defined therethrough. The link also includes a first extension member extending outwardly from the first side of the body member. The first extension member has a point P1 defined thereon. The link also includes a second extension member extending outwardly from the first side of the body member. The second extension member has a point P2 defined thereon. The link also includes a third extension member extending outwardly from the first side of the body member. The third extension member has a point P3 defined thereon. The first extension member, the second extension member, and the third extension member are spaced apart from each other.

Abstract: A drive mechanism includes a drive shaft and a sprocket drive assembly. The sprocket drive assembly includes a hub mechanically coupled to the drive shaft, a first side support secured to the hub, a second side support secured to the hub, and a plurality of engagement members each interposed between the first side support and the second side support. Each of the plurality of engagement members is rotatably secured to each of the first side support and the second side support. The drive mechanism further includes a track assembly which has a plurality of shoes which are secured to one another to form a track, and a plurality of drive lugs which are mounted to the plurality of shoes. Each of the plurality of drive lugs has a first grasping notch and a second grasping notch defined therein. The plurality of drive lugs includes a first drive lug and a second drive lug which are adjacent to each other.

Abstract: A track link assembly consists of two parallel arranged chains of links connected end to end, the links of each chain being connected by a joint including a link pin press fit in the bore of the outboard end collar. In order to limit the movement of the collar on the link pin and prevent excessive end play at the seal, a snap ring is fitted on a portion of each end of the link pin which extends outward from the bore of the outboard end collar. One or more protrusions on the outer surface of the boss protect the snap ring from being knocked off during use.
