Reaction Socket Assembly With Segmented Keys And Ramps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional reaction washers and socket assemblies do not provide a positive connection means for power-driven torque tools, leading to compromised connections, especially in horizontal or inverted orientations, and often result in damage due to improper mating and engagement issues.
Innovation Solution
A reaction socket assembly with a socket, lower part, and sleeve design that includes recesses, keyways, and keys to securely engage a compact reaction washer, allowing for a hands-free operation and improved load distribution, along with a compact reaction washer featuring serrations and locking elements for stable engagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional reaction washers are used with power-driven torque tools, then the tool can be operated, but the connection between the reaction washer and reaction socket is compromised in horizontal or inverted positions
Solution Approach 1:
The reaction washer is divided into multiple functional segments: a body portion with engagement features, a drive portion with drive elements, and multiple locking elements distributed around the perimeter. This segmentation allows each portion to perform its specific function independently, ensuring stable connection through positive engagement features rather than relying on friction or gravity-dependent contact.
Solution Approach 2:
The reaction socket assembly acts as an intermediary component between the power-driven torque tool and the reaction washer. It includes a socket portion that engages the drive portion of the washer, and a reaction washer interface that engages the body portion, providing a positive mechanical connection that transfers torque reliably regardless of tool orientation.
2Productivity
If traditional reaction washers are used, then the tool can function, but damage occurs due to insufficient engagement with the reaction socket assembly
Solution Approach 1:
The reaction washer incorporates pre-formed engagement features including drive elements in the drive portion and locking elements in the body portion. These features are designed to positively engage with corresponding features in the reaction socket assembly before torque application begins, ensuring proper alignment and preventing misengagement that could lead to damage.
Solution Approach 2:
The engagement features utilize curved or rounded geometries such as spherical drive elements and corresponding recesses, allowing for self-alignment and smooth engagement. The curved surfaces distribute contact stresses more evenly and prevent stress concentration that could lead to failure during torque application.
3Ease of operation
If traditional reaction washers are used, then the tool can operate, but connection differences prevent proper mating between the power-driven torque tool body and the reaction socket
Solution Approach 1:
The reaction washer is designed with universal engagement features that can interface with multiple types of power-driven torque tools. The drive portion with its standardized drive elements and the body portion with its locking elements provide a universal interface that accommodates various tool configurations, making the washer adaptable to different tool bodies and socket designs.
Solution Approach 2:
The reaction washer incorporates dynamic engagement features that adapt during operation. The locking elements are positioned to engage with corresponding features in the reaction socket assembly, and the engagement geometry allows for slight adjustments in alignment while maintaining secure connection, providing adaptability to variations in tool manufacturing tolerances and orientations.
