Reinforcement Fin Rolling Boot for High-Speed Radial Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rotating boots in modern gearings and joint assemblies face challenges with stability and service life at high rotational rates due to centrifugal forces, leading to material wear, deformation, and reduced lubrication, which are not effectively addressed by existing technologies.
Innovation Solution
The implementation of at least one circumferential reinforcement fin on the outer surface of the transition region of the rotating boot, which intercepts tangential forces and improves radial rigidity, combined with a design that reduces centrifugal forces by positioning the reinforcement fin close to the membrane region and using supporting and radial fins to enhance structural integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the wall thickness of the rotating boot is increased to improve radial rigidity, then the radial stability improves, but the production costs increase and the quality of the rotating boot may be reduced
Solution Approach 1:
The rotating boot is segmented by introducing circumferential reinforcement fins that divide the transition region into discrete structural segments. These fins create a ribbed structure that provides radial rigidity without requiring increased wall thickness throughout the entire boot, thereby reducing material costs while maintaining stability.
Solution Approach 2:
Instead of uniformly increasing wall thickness, the invention applies local reinforcement through circumferential fins positioned specifically in the transition region where radial rigidity is most needed. This localized approach provides the necessary structural support only where required, optimizing material usage and reducing overall production costs.
2Stability of the object's composition
If reinforcement fibers oriented tangentially are used in the rotating boot material to improve radial rigidity, then the radial stability improves, but the production costs increase
Solution Approach 1:
The invention replaces the need for complex tangential reinforcement fibers with discrete circumferential fins that segment the transition region. This segmentation provides the necessary radial rigidity through geometric structure rather than material composition, simplifying manufacturing and reducing costs.
Solution Approach 2:
The invention substitutes a mechanical structural solution (circumferential fins) for a material-based solution (tangential reinforcement fibers). The fins provide radial rigidity through their geometric configuration and structural arrangement, eliminating the need for expensive specialized fiber materials and complex material processing.
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
This solution enhances the radial stability and service life of rotating boots at high rotational rates by effectively managing centrifugal forces and preventing material deformation, thereby ensuring sufficient lubrication and reduced contact with adjacent components.
Implementation Method 1
The tangential forces are intercepted by this at least one reinforcement fin, even at high rotational rates, such that ultimately, the radial rigidity of the rotating boot is improved at high rotational rates.
Implementation Method 2
a boot with a grease load is substantially subjected to tangential forces... at high rotational rates, they are simply displaced outward, without improving the radial rigidity of the rotating boot

AI summary
A rolling boot that has improved stability especially at increased rotational speeds comprises a first fastening region, a second fastening region, a transition region adjacent to the first fastening region, as well as a diaphragm region adjoining the transition region, and at least on peripheral reinforcement fin is arranged on an external side of the transition region.
