Abstract: Construction machines using a rubber crawler are being diversified because the driver is less fatigued; however, under severe operating conditions, much damage occurs in the machine to make the latter unusable in a short time. This problem is solved herein. A rubber crawler characterized by comprising a core consisting of rectangular parellelepiped blocks (5) each having two longitudinally spaced through-holes (9) in the lower surface region and bars (4) inserted in the through-holes (9), the rectangular parellelepiped blocks (5) being arranged in zigzags with sprocket engaging holes (2) disposed therebetween, and the bars (4) being inserted in alternately corresponding through-holes (9) in adjacent rectangular parellelepiped blocks (5), the bars (4) being connected within the rectangular parellelepiped blocks (5) and embedded in the rubber crawler.

Abstract: In hinge chains with rubber bearings (5), in which rubberized tubular steel bushings are used as bearings for track pins (20), the bolt ends are normally provided with threaded studs to allow the steel bushings (10) to be braced immovably by screw nuts against one another and against the track pins (20). In order to lengthen the useful life of the rubber bearing (5) and to reduce maintenance, a rubberized expanding bushing (10) with at least one dividing joint (11) is proposed instead of a tubular bushing. The internal diameter (25) of the bushing (10) which is forced in is les than the diameter (27) of the track pin (20). The inserted track pin (20) expands the bushing (10) which is forced into the chain link (1). The track pin (20) is braced inside the bushing (10) and secured along its length by friction and around its periphery by friction and/or positive engagement. No screw joints are needed for bracing the bushing (10) and use of the threaded portion of the screw joint increases the rubber bearing-surface. This improves the useful life of the rubber bearing and reduces maintenance.

Abstract: A crawler track mechanism comprises a plurality of track plates each mounted on track chain links, the chain links (10) being interconnected by bushes having an outer sleeve (4) rotatably journalled on an inner sleeve (2) which in turn is rotatably journalled on a central cylindrical pin (1). A drive sprocket (60) (and if required, an idler sprocket) comprises recesses (62) having a semi-circular cross section to receivably locate the bushes. The bushes, by virtue of the relative rotation between the pin (1), the inner sleeve (2) and the outer sleeve (4), reduce friction and wear between the drive sprocket and the chain bushes.

Abstract: In some implementations, a bushing may include a cylindrical body having an at least partially annular configuration. The cylindrical body may define a radial axis and may include an inner circumferential surface, an outer circumferential surface, a first end, and a second end. The inner circumferential surface may be configured to rotatably receive an outer surface of a pin of a track link joint. The outer circumferential surface may be configured to be rotatably received within a first counterbore of a first track link of the track link joint. The bushing may include at least one groove extending radially into the outer circumferential surface around the radial axis. The at least one groove may be configured to receive a first seal of the track link joint. The first seal may form a first radial seal between the outer circumferential surface and a first inner surface of the first counterbore.

Abstract: A track pad (110) may include a base member (202) and a roller path member (208) extending from the base member (202). The roller path member (208) may include a roller path surface (210) for engaging with a roller (118) of a machine (100). The roller path member (208) may include a leading side (208a) and a trailing side (208b) in a direction of travel of the machine (100). The roller path member (208) may include a hardened region (302) that extends from the roller path surface (210) and a body region (304) adjacent the hardened region (302). The hardened region (302) may have a greater hardness than the body region (304). The hardened region (302) may have a uniform depth from the leading side (208a) to the trailing side (208b) of the roller path member (208).

Abstract: A track link (20) includes an elongate link body (32) formed of a link body material (76) that varies in hardness to form a first lower hardness zone (78), a second lower hardness zone (80), and a higher hardness zone (82). The higher hardness zone (82) includes an upper rail surface (44) of the elongate link body (32) and extends substantially throughout the elongate link body (32) outside of the first and second lower hardness zones (80), which surround the track pin bores (48,54). Related methodology for making a track link (20) is also disclosed.
