Wear Runner Style Wear Member With Ramped Locking for Buckets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Material displacement apparatuses, such as excavating buckets, experience wear due to abrasive contact with displaced materials, leading to premature wear of assemblies affixed to the bucket surface, which can be costly to replace.
Innovation Solution
A wear member assembly comprising a base affixed to the bucket, a wear member with securement and push-out ramps, and a locking pin assembly that allows for easy replacement of worn components, enhancing operability and longevity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If a wear member assembly is affixed to the bucket surface to prevent wear, then the bucket's service life is extended, but the wear member assembly itself wears prematurely and requires frequent replacement
Solution Approach 1:
The wear member assembly is divided into separate replaceable components including the wear member, locking pin assembly, and base, allowing individual parts to be replaced independently when worn, extending the overall system's service life while reducing replacement costs
2Ease of manufacture
If the wear member assembly is designed to be replaceable, then replacement cost is reduced, but the complexity of the assembly increases
Solution Approach 1:
The assembly is segmented into modular components (wear member, locking pin assembly, base) that can be manufactured separately and assembled together, reducing overall manufacturing complexity while enabling cost-effective replacement of individual worn parts
Solution Approach 2:
Multiple functional elements are combined into integrated assemblies such as the locking pin assembly that includes the locking pin, ramps, and securing features, simplifying the replacement process while maintaining ease of manufacture

AI summary
The present disclosure is directed to a wear member attachable to a base on ground engaging equipment. The wear member may include a top wear surface, a bottom surface opposite the top wear surface, a first lateral side, a second lateral side opposite the first lateral side, and a projection projecting downward from the bottom surface. The projection may include an internally disposed first securement ramp configured to contact a corresponding securement ramp on a base. The internally disposed first securement ramp may be spaced from the first lateral side and from the second lateral side. A lock-receiver opening may extend from the top wear surface to the bottom surface.
