Radial-Elevation Clamping Ring for High-Force Compact Sleeve Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing clamping rings for connecting shafts and sleeves lack the ability to provide a high clamping force with minimal dimensions and low mass inertia while maintaining good balance quality and low production costs.
Innovation Solution
A clamping ring design featuring radial elevations and a radial clamping gap, with asymmetrical contours and varying wall thicknesses, allows for uniform distribution of clamping force and includes a securing element to prevent rotation and loss, produced through methods like laser cutting or stamping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If the clamping ring uses a rounded bulge design for receiving a screw, then the clamping force is increased, but the dimensions and cross section increase
Solution Approach 1:
The clamping ring features radial elevations that create local thickened regions at specific positions around the circumference. These local elevations concentrate the clamping force at discrete points rather than distributing it uniformly, allowing high clamping force with a thinner overall ring cross-section. The receiving hole for the tensioning screw is positioned in one of these radial elevations, enabling effective force application at a localized area.
2Force
If the clamping ring uses a rounded bulge design for receiving a screw, then the clamping force is increased, but the mass inertia increases
Solution Approach 1:
Instead of adding material uniformly throughout the clamping ring, the design incorporates radial elevations that add material only where needed to generate clamping force. This localized material distribution achieves the required clamping force while minimizing the overall mass of the ring, thereby reducing mass inertia and improving balance quality.
3Force
If the clamping ring has asymmetrical radial elevations, then the clamping force is distributed uniformly over the circumference, but the manufacturing complexity increases
Solution Approach 1:
The clamping ring is divided into multiple radial elevations (typically three) that are distributed around the circumference. Each elevation is asymmetrical in shape, but the overall pattern is regular and repeating. This segmentation allows the clamping force to be distributed uniformly around the sleeve circumference, while the regular repeating pattern maintains manufacturing simplicity through standardized production processes.
Solution Approach 2:
The radial elevations are designed with asymmetrical contours rather than symmetrical shapes. This asymmetry enables the elevations to effectively engage with the sleeve surface and distribute clamping force uniformly around the circumference. The asymmetrical shape allows one side of each elevation to contact the sleeve while the other side provides structural support, optimizing force distribution.
