Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional damping devices with axial dampers connected by pivot bearings or ball joints suffer from radial bearing clearance issues, leading to increased stress and potential malfunction due to radial impacts, which can result in costly maintenance and reduced effectiveness in damping axial relative movements between components.
Innovation Solution
A damping device featuring a bending joint with a joint section that can be resiliently bent about axes perpendicular to the axial direction, providing a rigid connection and minimizing axial backlash, thus reducing stress on the axial damper and allowing immediate damping of axial relative movements while being cost-effectively produced.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If pivot bearings or ball joints are used to connect the axial damper to components, then flexibility perpendicularly to the axial direction is provided, but radial bearing clearance causes radial impacts and increased stress during axial movement
Solution Approach 1:
The invention extracts and eliminates the pivot bearing or ball joint from the connection between the axial damper and components. Instead, it uses a rigid connection that directly couples the axial damper to the components, removing the source of radial bearing clearance and radial impacts while maintaining the desired flexibility through the damper's own design
Solution Approach 2:
The invention segments the connection function by separating the axial damping function from the perpendicular flexibility function. The axial damper handles axial movements directly through its damping mechanism, while perpendicular flexibility is achieved through the overall system configuration rather than through intermediate bearings
2Adaptability or versatility
If pivot bearings or ball joints are used to provide perpendicular flexibility, then the axial damper can accommodate component misalignment, but the bearing clearance increases continuously due to radial impacts
Solution Approach 1:
The invention removes the pivot bearing or ball joint that causes continuous bearing clearance increase. The rigid connection eliminates radial impacts entirely, preventing the progressive wear and clearance increase that limits bearing service life
Solution Approach 2:
The invention replaces the expensive, long-lived but clearance-prone pivot bearings with a simpler rigid connection that, while potentially less flexible, eliminates the progressive degradation issue and reduces overall system complexity and cost
3Adaptability or versatility
If pivot bearings or ball joints are used to connect the axial damper, then perpendicular flexibility is achieved, but the device complexity and cost increase
Solution Approach 1:
The invention extracts and eliminates the complex pivot bearing or ball joint assembly from the connection mechanism. The rigid connection simplifies the overall device structure, reducing the number of parts, assembly steps, and maintenance requirements while achieving the necessary functionality
Solution Approach 2:
Instead of using flexible bearings to achieve perpendicular flexibility, the invention inverts the approach by using a rigid connection and allowing the axial damper itself to accommodate perpendicular movements through its damping mechanism, thereby simplifying the connection architecture
