Master Link Assembly for Track Chain Disassembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing master link assemblies for track chains, such as those disclosed in U.S. Pat. No. 6,783,196, may not be suitable for all applications, particularly in offset link chains, where a more efficient and cost-effective disassembly method is needed to reduce maintenance costs and machine downtime.
Innovation Solution
A master link assembly with a link body featuring a first and second aperture of different diameters, a threaded fastener, and a cylindrical flange, which allows for the disassembly of the track chain by adjusting the aperture diameters through the use of fasteners to securely couple and decouple the master links using a cartridge assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If a traditional master link assembly is used for track chain disassembly, then the chain can be separated, but the process is time-consuming and complex
Solution Approach 1:
The master link assembly is divided into separate components: a master link with a body and aperture, and a separate fastening mechanism comprising a fastener and clamp. This segmentation allows for quicker assembly and disassembly operations while maintaining structural integrity during operation.
Solution Approach 2:
The master link assembly incorporates a dynamic fastening system where the clamp can be positioned at different locations along the master link body. The fastener can be inserted and removed to change the clamping position, enabling rapid adjustment and disassembly without complex tools or procedures.
2Adaptability or versatility
If the master link uses multiple apertures of different diameters, then versatility is improved, but manufacturing complexity increases
Solution Approach 1:
The master link body features multiple apertures with different diameters at specific locations, each optimized for different fastener sizes and clamping requirements. This local variation in aperture quality provides versatility for different track chain configurations while maintaining precise manufacturing tolerances for each specific aperture location.
3Strength
If a flange is added to the master link, then structural integrity is improved, but device complexity increases
Solution Approach 1:
The flange is integrated directly into the master link body as a unified component rather than being a separate part. This merging provides enhanced structural integrity and clamping surface area while avoiding the complexity of additional fasteners or separate clamping components. The flange forms an integral part of the master link that distributes loads effectively.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables quick and efficient disassembly of the track chain, reducing maintenance costs and machine downtime by allowing for easy removal and reassembly of the master links, while maintaining structural integrity and durability.
Implementation Method 1
a threaded first fastener that is configured to extend through the link body across the third aperture
Implementation Method 2
a substantially cylindrical flange is positioned around the first aperture

AI summary
A master link (62) for a track chain (22) is disclosed. The master link may include a link body extending from a first end (63A) to a second end (63B) and a plurality of apertures (66A, 66B, 66C, 66D) extending through the link body. The plurality of apertures may include a first aperture (66A) positioned proximate the first end, a second aperture (66B) unconnected to the first aperture and positioned proximate the second end, and a third aperture (66D) arranged between the first and second apertures. A first gap (76B) may extend between and connect the third and second apertures. The master link may also include a threaded first fastener (60) that is configured to extend through the link body across the third aperture.
