Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing magnetic-hydraulic double-suspension bearing experiment table systems suffer from coaxiality errors due to assembly processing errors, which affect the motion characteristics.
Innovation Solution
The system includes a fixed bracket with concentric left and right supporting parts, radial stators with stops, and specific hole configurations to ensure concentricity, along with a motor, coupling, bell hood, and sealing components to reduce assembly errors and improve coaxiality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If long bolts are used to connect the radial end covers and radial stators to the fixed bracket, then the structural integrity is improved, but the coaxiality error increases due to multiple mounting parts and stops
Solution Approach 1:
The fixed bracket is divided into left and right supporting parts that are concentric with each other, allowing separate mounting of radial stators while maintaining overall coaxiality. This segmentation reduces the cumulative error from multiple mounting interfaces.
Solution Approach 2:
Concentric reference features are introduced as intermediaries between the mounting components and the fixed bracket. These reference features serve as mediators to ensure coaxial alignment, reducing the coaxiality error caused by multiple mounting parts and stops.
2Stability of the object's composition
If multiple mounting parts and stops are used to connect components from left to right, then the assembly stability is improved, but the concentricity error of the magnetic-hydraulic double-suspension bearing increases
Solution Approach 1:
The assembly is segmented into modular components (left radial end cover assembly, right radial end cover assembly) that are independently mounted on concentric supporting parts. This reduces the cumulative concentricity error compared to a single continuous assembly from left to right.
Solution Approach 2:
Concentric reference features on the left and right supporting parts act as intermediaries to maintain concentricity during assembly. These references enable stable assembly while minimizing concentricity error accumulation.
3Manufacturing precision
If radial stators are mounted with stops to ensure concentricity, then the positioning accuracy is improved, but the device complexity increases due to additional processing requirements
Solution Approach 1:
Stops are added only at specific critical locations on the radial stators where concentricity control is most needed, rather than throughout the entire component. This localized approach improves positioning accuracy while minimizing additional processing complexity.
Solution Approach 2:
The concentric reference features and stops are pre-formed on components during manufacturing, so that concentricity is established before final assembly. This preliminary action reduces the need for complex adjustments during assembly.

AI summary
The present invention provides a magnetic-hydraulic double-suspension bearing experiment table. In the experiment table, four blind holes are uniformly processed on left and right side surfaces of the two radial stators for magnetic-hydraulic double-suspension bearing; four countersunk through holes are uniformly processed on left side surfaces of the left supporting part of the fixed bracket and the right supporting part of the fixed bracket, and the radial stators for magnetic-hydraulic double-suspension bearing are fixedly connected to the upper end of the left supporting part of the fixed bracket by countersunk screws. In addition, the two radial stators for magnetic-hydraulic double-suspension bearing are processed with stops to ensure that the two radial stators for magnetic-hydraulic double-suspension bearing are concentric with the left supporting part of the fixed bracket and the right supporting part of the fixed bracket.
