Tapered Bushing Splint Joint for Drive Shaft Disassembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drive shaft systems lack an efficient mechanism for disassembly and reassembly, which complicates repair and installation processes.
Innovation Solution
A splint joint design featuring a tapered bushing receptacle with a keyed aperture and push bolts allows for the disassembly of a drive shaft by sliding the bushing away from the receptacle, facilitating the separation of drive shaft sections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a drive shaft is designed with a fixed connection mechanism, then the connection strength and torque resistance are improved, but the ease of disassembly and reassembly deteriorates
Solution Approach 1:
The connection mechanism transitions from a static fixed state to a dynamic adjustable state. The splint joint includes a movable component that can be shifted along the drive shaft using a hammer and drift, allowing the connection to be easily assembled and disassembled while maintaining strength during operation
Solution Approach 2:
The drive shaft connection is divided into separable components including the splint, joint, and movable element. This segmentation allows the connection to be broken down into discrete parts that can be independently manipulated for assembly and disassembly while maintaining structural integrity when connected
2Ease of repair
If a drive shaft uses a simple connection mechanism, then the ease of disassembly is improved, but the torque resistance and connection reliability deteriorates
Solution Approach 1:
The splint joint incorporates a curved or rounded interface that engages with the drive shaft splines. This curved geometry provides mechanical advantage and ensures reliable torque transmission while allowing smooth movement during assembly and disassembly operations
Solution Approach 2:
The splint joint acts as an intermediary component between drive shaft sections. This mediator element facilitates easy connection and disconnection while maintaining reliable torque transmission through its specially designed engagement surfaces and geometry

Function Achieved in This Case
Enables efficient disassembly and reassembly of drive shafts, enhancing repair and installation processes by providing a secure and torque-resistant connection while allowing for easy separation of components.
Implementation Method 1
A bushing having a tapered body is inserted into the receptacle tapered interior and the receptacle and bushing are immovably affixed with bolts
Implementation Method 2
The bushing has a keyed aperture which receives a keyway drive shaft
Implementation Method 3
Push bolts allow the bushing to be urged away from the receptacle allowing the drive shaft to be disassembled

AI summary
The Drive Shaft Splint Joint is a receptacle with a tapered interior and with a drive shaft extending from the receptacle. A bushing having a tapered body is inserted into the receptacle tapered interior and the receptacle and bushing are immovably affixed with bolts. The bushing has a keyed aperture which receives a keyway drive shaft. Push bolts allow the bushing to be urged away from the receptacle allowing the drive shaft to be disassembled.
