Multi-Surface Corner Segment Mounting for Bolt Shear Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bolt-on ground engaging tools (GETs) for work implements, such as wheel loader buckets, are limited in size due to stress and load constraints, leading to reduced wear life and increased risk of bolt shear and structural failure.
Innovation Solution
A corner segment design with multiple bolt-holes on various surfaces, allowing for secure mounting to a work implement using bolts, which reduces the risk of bolt shear and provides additional support, thereby increasing the size and wear life of the GET.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If the size and thickness of bolt-on GETs are increased, then wear life is improved, but stress on mounting hardware increases leading to bolt shear
Solution Approach 1:
The corner GET is divided into multiple segments with separate mounting interfaces. The corner GET includes a first mounting surface with first mounting holes and a second mounting surface with second mounting holes, allowing the GET to be secured at multiple discrete locations rather than relying on a single mounting point. This segmentation distributes the stress across multiple bolts and mounting surfaces.
Solution Approach 2:
The invention adds a third dimension to the mounting configuration by utilizing both a first mounting surface (e.g., top surface) and a second mounting surface (e.g., side surface) of the corner GET. This multi-surface mounting approach transforms a two-dimensional mounting problem into a three-dimensional solution, distributing loads across different spatial planes and reducing stress concentration on any single bolt.
