Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for connecting an adapter shaft to a shaft lack effective security against loss and rotation in a force-fitting manner, particularly in axial and circumferential directions, and require additional mechanisms beyond a simple clamping ring.
Innovation Solution
A clamping ring is mounted on the adapter shaft with a radially uninterrupted threaded bore, accommodating a screw part that exerts pressure, and a cylinder bolt is positioned in recesses on both the adapter shaft and clamping ring, allowing for axial and circumferential protection without additional mechanisms, utilizing axial slots for elastic deformation and a chamfer for easy insertion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple clamping ring is used for connecting the adapter shaft to the shaft, then the device complexity is reduced, but the protection against loss and rotation in axial and circumferential directions is insufficient
Solution Approach 1:
The patent combines multiple protective functions into a single integrated clamping ring design. The clamping ring incorporates both axial retention (through the cylinder bolt and recess arrangement) and circumferential retention (through the flattened area and radial pressure) functions, eliminating the need for separate retention mechanisms and reducing overall device complexity while maintaining reliability
Solution Approach 2:
The clamping ring acts as an intermediary component between the adapter shaft and the hollow shaft. It mediates the connection by distributing radial pressure through the flattened area and providing both axial and circumferential retention, thereby achieving secure connection without requiring complex additional mechanisms
2Ease of manufacture
If axial slots are introduced in the adapter shaft, then the ease of manufacture is improved and elastic deformation is enabled, but the structural integrity may be compromised
Solution Approach 1:
The adapter shaft is segmented by introducing axial slots that divide the shaft wall into discrete sections. This segmentation enables elastic deformation when the clamping ring applies radial pressure, allowing the shaft to flex and conform to the hollow shaft while maintaining overall structural integrity through the remaining material connections
3Ease of manufacture
If the cylinder bolt is arranged as a cylindrical disk, then the ease of manufacture is improved, but the protection against loss and anti-rotation protection may be reduced
Solution Approach 1:
The cylindrical disk-shaped cylinder bolt is designed to perform multiple functions simultaneously. Its cylindrical geometry with a head provides both axial retention (preventing loss in the axial direction) and circumferential retention (preventing rotation) through its interaction with the recess in the adapter shaft and the flattened area, achieving universal retention functionality with a simple manufacturable form
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 solution provides a secure, cost-effective force-fitting connection with enhanced protection against loss and rotation, enabling a balanced and uncomplicated assembly process while maintaining the adapter shaft's elasticity and uniform contact with the solid shaft.
Implementation Method 1
Because of the axial slots, the adapter shaft is elastically deflectable and thus is able to be pressed against the hollow shaft as soon as the threaded pin exerts pressure on the adapter shaft. The contracting, in particular the shrink-fitting, is brought about in the process.
Implementation Method 2
a cylinder bolt is accommodated in a first recess of the clamping ring, which projects radially inward into a second recess introduced into the adapter shaft, in particular projects into it, especially in order to form a protection against loss and an anti-rotation protection acting in an axial direction and in a circumferential direction
Implementation Method 3
the clamping ring has a radially uninterrupted threaded bore into which a screw part is screwed, in particular a threaded pin, which exerts pressure on the adapter shaft
