초록 ▼

A master link for a track chain assembly is provided. The master link includes a body portion having first and second spaced apart apertures extending therethough. A gap extends radially outward from one of the first and second apertures. At least one fastener operatively engages an aperture that extends through the gap. As the fastener is secured the width of the gap is reduced thereby reducing the diameter of one of the first and second apertures providing a clamping force.

1. A master link for a track chain assembly comprising:a unitary body portion having a first side, a second side positioned opposite the first side, a shoe surface adapted to receive a track shoe, and a rail surface positioned opposite the shoe surface;a first end portion defining a first aperture extending through the body portion from the first side to the second side;a second end portion defining a second aperture extending through the body portion from the first side to the second side, said second aperture being spaced from said first aperture; andsaid unitary body portion including a gap extending radially from said first and said second apertures. 2. The master link of claim 1, including at least one aperture extending from the shoe surface through said gap towards the rail surface. 3. The master link of claim 2, including a fastener operatively engaging said aperture and operatively reducing the width of said gap upon securing of said fastener thereby changing the diameter of said one of said first and second apertures. 4. The master link of claim 3, wherein said master link is an offset link. 5. The master link of claim 3, wherein said master link is a straight link. 6. The master link of claim 3, including an aperture positioned on each side of a central axis and extending from the shoe surface through said gap towards the rail surface. 7. The master link of claim 6, wherein said apertures are positioned at a predetermined angle relative to said central vertical axis. 8. The master link of claim 6, including at least one exit hole interposed said apertures and extending from said first side through to said second side. 9. The master link of claim 6, including a fastener positioned in each aperture and extending through a track shoe and fastenably securing said track shoe to the shoe surface. 10. A track chain assembly having opposite ends capable of being coupled together to form a closed loop, said track chain assembly comprising:a plurality of subassemblies each being connected to an adjacent subassembly;a one-piece inner master link and a one-piece outer master link connecting the opposite ends of the track chain assembly together;wherein each of said one-piece inner master link and said one-piece outer master link, each includes:a body portion having a first side, a second side positioned opposite the first side, a shoe surface adapted to receive a track shoe positioned opposite a rail surface;said body portion having a first end portion defining a first aperture extending from the first side to the second side;said body portion having a second end portion defining a second aperture extending from the first side to the second side, said second aperture being spaced from the first aperture; andsaid body portion including a gap extending radially from said first and said second apertures. 11. The track chain assembly of claim 10, wherein each of said plurality of sub assemblies includes a cartridge assembly, an inner link, an outer link and a track shoe. 12. The track chain assembly of claim 10, wherein each of said one-piece inner master link and said one-piece outer master link is an offset link. 13. The track chain assembly of claim 12, including a pair of one-piece inner master links and a pair of one-piece outer master links. 14. The track chain assembly of claim 10, wherein each of said one-piece inner master link and said one-piece outer master link is a straight link. 15. The track chain assembly of claim 10, wherein each of said one-piece inner master link and said one-piece outer master link includes at least one aperture extending from the shoe surface through said gap towards the rail surface. 16. The track chain assembly of claim 15, including a fastener operatively engaging said aperture and operatively reducing the width of said gap upon securing of said fastener thereby changing the diameter of said first and second apertures. 17. The track chain assembly of claim 16, wherein said fastener operativ ely securing of a track shoe to said shoe surface.
