Vibration-Isolating Bearing Mount With Interchangeable Inserts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vibration-isolating bearing devices require separate configuration and manufacturing for each application, and previous designs face issues with effective positioning and insertion of elastomer bodies, making it difficult to adapt to varying requirements.
Innovation Solution
The inner body of the bearing device features partitions with gaps where vibration-isolating inserts can be easily arranged and exchanged, allowing for customizable vibration isolation in three spatial directions, with the option for interchangeable inserts to adapt to different tasks without direct contact between the inner body and the bearing housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the inner body is permanently connected to the bearing housing via elastomer bodies, then vibration isolation is achieved in all three spatial directions, but the device must be individually configured and manufactured for each application
Solution Approach 1:
The bearing device is divided into modular components: a bearing housing, an inner body with partition walls, and separate vibration-isolating inserts. The inserts can be independently selected and exchanged based on specific application requirements, allowing the same bearing housing and inner body to be adapted to different vibration isolation needs without remanufacturing the entire device.
Solution Approach 2:
The bearing housing and inner body are designed as universal components that can accommodate different types and configurations of vibration-isolating inserts. This allows a single bearing device platform to serve multiple applications by simply changing the inserts, eliminating the need for individual configuration and manufacturing for each application while maintaining reliable vibration isolation.
2Reliability
If several elastomer bodies are arranged between the inner body and bearing housing with gaps, then the insulating effect is improved, but the inserts are not effectively secured in position and correct insertion is problematic
Solution Approach 1:
The bearing device is divided into modular components: a bearing housing, an inner body with partition walls, and separate vibration-isolating inserts. The inserts can be independently selected and exchanged based on specific application requirements, allowing the same bearing housing and inner body to be adapted to different vibration isolation needs without remanufacturing the entire device.
Solution Approach 2:
The partition walls act as intermediaries that structure the space between the inner body and bearing housing. They create defined intermediate spaces that guide and secure the inserts in specific positions, ensuring correct insertion while maintaining the vibration isolation gaps. The partition walls mediate between the need for secure positioning and the need for insulation gaps.
3Reliability
If the inserts extend beyond the space between partition walls, then direct contact between inner body and bearing housing is prevented, but the configuration becomes more complex
Solution Approach 1:
The bearing device is divided into modular components: a bearing housing, an inner body with partition walls, and separate vibration-isolating inserts. The inserts can be independently selected and exchanged based on specific application requirements, allowing the same bearing housing and inner body to be adapted to different vibration isolation needs without remanufacturing the entire device.
Solution Approach 2:
The inserts are designed to self-secure in the intermediate spaces created by the partition walls. Their elastic prestress causes them to naturally extend beyond the partition walls, automatically preventing direct contact between the inner body and bearing housing without requiring additional complex configuration or assembly steps. The inserts serve themselves by creating the necessary separation.
