Vibration Isolation Apparatus Elastic Part Compression Method
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vibration isolation apparatuses lack flexibility in setting the compression degree of the elastic body between the inner and outer cylinders, as the elastic body is integrally formed with the cylinders, limiting the ability to adjust the compression degree independently.
Innovation Solution
A method involving molding and press-fitting elastic parts between the inner and outer cylinders, allowing for controlled compression and flexible setting of the elastic body's compression degree, using a specialized assembly jig to ensure precise positioning and bonding of the elastic parts with thermosetting adhesive.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the elastic body is integrally formed with the inner cylinder and outer cylinder, then the structural integrity is improved, but the flexibility in setting the compression degree of the elastic body deteriorates
Solution Approach 1:
The elastic body is divided into multiple independent elastic parts (first elastic parts and second elastic parts) that are separately molded and then assembled between the inner and outer cylinders. This segmentation allows each elastic part to be independently compressed to different degrees, providing flexibility in setting the compression degree while maintaining structural integrity through their collective arrangement.
2Force
If the outer cylinder is narrowed to compress the elastic body, then the compression degree is improved, but the flexibility in setting the compression degree deteriorates
Solution Approach 1:
The compression degree of the elastic body is made adjustable by selectively arranging different types of elastic parts (first elastic parts with higher compressibility and second elastic parts with lower compressibility) in different radial positions. This dynamic configuration allows the compression degree to be freely set by changing the arrangement pattern, rather than being fixed by the outer cylinder's narrowing degree.
3Adaptability or versatility
If different rubber materials are used for the elastic body, then the performance customization is improved, but the manufacturing complexity deteriorates
Solution Approach 1:
The elastic body is segmented into multiple elastic parts that can be made from different rubber materials. Each elastic part can be independently molded from suitable rubber materials based on performance requirements, and then assembled together. This approach allows performance customization without requiring complex insert molding processes, as each part can be manufactured separately and then combined.

Function Achieved in This Case
This approach increases flexibility in setting the compression degree of the elastic body, preventing adhesive and phosphate film breakdown, and allows for the use of different rubber materials without the complexities of insert molding, enhancing the vibration isolation apparatus's performance.
Implementation Method 1
compressing in which the elastic parts are pressed against positions in which the elastic parts are provided to the inner member so that the elastic parts are compressed to have a size equivalent to a size in which the elastic parts fit between the inner member and the outer cylinder
Implementation Method 2
fastening the elastic parts to the inner member and the outer cylinder
