Trunnion Socket Retention Assembly Wear Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional trunnion and socket assemblies experience wear on fasteners and split caps due to the trunnion pressing against them, leading to potential failure and reduced durability during pivotal movement operations.
Innovation Solution
A retention assembly comprising cap elements and a ring member with strategically aligned apertures for receiving mechanical fasteners, where the ring member's inner diameter is greater than the trunnion's outer diameter, ensuring secure retention and distribution of forces across the fasteners, thereby reducing shear forces and enhancing durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If split caps are used to retain the trunnion within the socket, then the trunnion is retained in the socket, but wear occurs on the fasteners and split caps due to the trunnion pressing against them
Solution Approach 1:
The retention assembly is divided into multiple cap elements (first cap element and second cap element) that work together with a ring member. This segmentation allows the retention function to be distributed across multiple components, with the ring member specifically designed to prevent direct contact between the trunnion and cap elements, thereby reducing wear on individual components while maintaining secure retention.
2Reliability
If the ring member's inner diameter is greater than the trunnion's outer diameter, then wear on fasteners and cap elements is reduced, but the retention mechanism becomes more complex
Solution Approach 1:
The retention assembly uses a nested structure where the ring member surrounds the cap elements, which in turn secure the trunnion. The ring member is positioned within the socket cavity and envelops the cap elements, creating a nested arrangement. This nesting allows the components to work together in a compact configuration while the ring member's larger inner diameter provides the necessary clearance to reduce wear on internal components.

AI summary
A trunnion and socket assembly is provided. The trunnion and socket assembly includes a trunnion, a socket, and a retention assembly. The trunnion includes a first portion and a second portion, the second portion defining an outer diameter. The retention assembly includes at least two cap elements and a ring member. The cap elements are coupled in an abutting relationship with a first surface of the socket. The cap elements have a second surface and a third surface. The ring member is adapted to be coupled in an abutting relationship with the third surface of each of the cap elements. The ring member has a fourth surface and a fifth surface. The ring member defines an inner diameter that is greater than the outer diameter of the second portion of the trunnion.
