Actuation Bearing Support Ring Vibration Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional actuating bearings for clutches experience undesired release of the support ring from the bearing inner ring during operation, leading to malfunctions and potential damage due to vibrations.
Innovation Solution
The support ring is designed with a circumferential contact surface that is spring-like supported against the bearing inner ring, featuring a spring leg angled from the support ring, which is preferably made of spring steel, to prevent detachment. This design includes a peripheral contact surface that is radially prestressed against the bearing inner ring, and can be manufactured with a connecting ring body and fastened to a magnet holding device for enhanced stability and cost-effectiveness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional support ring design is used, then the structure is simple, but the support ring detaches from the inner bearing ring during operation due to vibrations
Solution Approach 1:
The support ring is designed with a spring element that provides dynamic elasticity, allowing it to adapt to vibrations and maintain continuous contact with the inner bearing ring. The spring constant is specifically selected to match the vibration characteristics of the actuating bearing, transforming the rigid support ring into a dynamic component that absorbs vibrational energy while preventing detachment.
Solution Approach 2:
The contact surface area between the support ring and inner bearing ring is increased through a circumferential contact design. This parameter change distributes the contact forces over a larger area, improving retention reliability during vibrations while maintaining structural simplicity.
2Reliability
If the contact area is increased to prevent detachment, then reliability improves, but manufacturing complexity increases
Solution Approach 1:
The support ring is segmented into a base ring and an integrated spring element. This segmentation allows the spring component to be manufactured separately using standard spring manufacturing processes, then assembled with the base ring through simple joining methods, maintaining ease of manufacture while achieving the required circumferential contact area for reliable retention.
3Reliability
If a spring element is added to provide preload, then retention reliability improves, but device complexity increases
Solution Approach 1:
The spring element is merged with the support ring structure itself, forming an integrated component rather than a separate assembly. The spring is formed as an integral part of the support ring through processes like stamping or extrusion, combining the support function and spring function into a single manufactured part, thus improving retention reliability without significantly increasing device complexity.
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 reliably prevents the support ring from detaching from the bearing inner ring, even under vibration, ensuring stable operation and reducing manufacturing costs through the use of plastic and metal components.
Implementation Method 1
The support ring for the preload spring has a circumferential contact surface with which the support ring is spring-like supported in a spring-like manner against the inner bearing ring
Implementation Method 2
The design of the support ring allows for an advantageous increase in the contact area where the bearing surface rests against the inner bearing ring
