Breaking Hammer Tool Seal Assembly for Wear-Resistant Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current sealing arrangements in breaking hammers suffer from wear resistance issues and complex structures, leading to inefficiencies in sealing effectiveness and tool longevity.
Innovation Solution
A two-part seal configuration is introduced, comprising a resilient first seal element and a rigid second seal element. The first seal element is made of a durable, resilient material and is fastened to the body of the breaking hammer, while the second seal element, made of a different material, is only fastened to the first seal element, allowing for transverse movement and providing additional protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a single seal element is used, then the structure is simple, but the wear resistance is poor
Solution Approach 1:
The seal is divided into two distinct seal elements: a first seal element with a first sealing surface and a second seal element with a second sealing surface. Each element is made of different materials optimized for specific functions, with the first element providing resilient sealing and the second element providing wear resistance. This segmentation allows each component to specialize in one function rather than requiring a single material to perform both functions simultaneously.
Solution Approach 2:
The invention employs two different materials for the two seal elements. The first seal element uses a resilient material capable of elastic deformation for effective sealing contact, while the second seal element uses a wear-resistant material to withstand abrasive conditions. This composite approach combines the advantages of different materials to achieve both good sealing properties and high wear resistance.
2Reliability
If a resilient seal material is used, then sealing properties are good, but wear resistance deteriorates
Solution Approach 1:
The seal is divided into two distinct seal elements: a first seal element with a first sealing surface and a second seal element with a second sealing surface. Each element is made of different materials optimized for specific functions, with the first element providing resilient sealing and the second element providing wear resistance. This segmentation allows each component to specialize in one function rather than requiring a single material to perform both functions simultaneously.
Solution Approach 2:
Different regions of the seal have different material properties tailored to their specific functions. The first seal element uses a resilient material with high elasticity for effective sealing contact, while the second seal element uses a hard, wear-resistant material for abrasive environments. Each local region's material quality is optimized for its specific operational requirements.

Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The seal assembly offers improved wear resistance, simplified structure, and enhanced sealing properties, extending the operational life of both the seal and the breaking hammer while reducing maintenance needs.
Implementation Method 1
the resilient first seal element of the seal allows the rigid second seal element to move transversally together with the tool relative to the sealing housing
Implementation Method 2
the sealing of the first seal element is based on resilient material of the first seal element being urged or pressed against an outer surface of the tool
