Integrated Anti-Vibration Mount Structure for Simpler Machine Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anti-vibration mounts for rotating electric machines are complex to manufacture due to their high number of elements, which complicates the minimization of vibration transfer from the rotor to the machine's structural components.
Innovation Solution
The proposed anti-vibration mount consists of a first and second support part separated by a gap, with at least one damping module comprising enveloping surfaces and vibration damping elements connecting these surfaces. This design decouples the machine from its foundation, effectively reducing vibration transfer.

Engineering Contradiction Analysis
1Object-affected harmful factors
If traditional support structures with multiple elements (mounting plates, reaction plates, intermediate support members, elastomeric layers) are used to minimize vibration transfer, then vibration isolation performance is improved, but manufacturing complexity increases
Solution Approach 1:
The patent combines multiple traditional support structure elements (mounting plates, reaction plates, intermediate support members, and elastomeric layers) into a single integrated anti-vibration mount body. The mount body includes integrated first and second support portions, first and second enveloping surfaces, and vibration damping elements, eliminating the need for separate mounting plates and reaction plates while maintaining vibration isolation functionality.
Solution Approach 2:
The anti-vibration mount is segmented into functional zones: first and second support portions for structural support, first and second enveloping surfaces for constraining the damping element, and vibration damping elements for vibration isolation. This segmentation allows each component to perform its specific function efficiently within a unified structure.

This segmentation allows each component to perform its specific function efficiently within a unified structure.
Solution Approach 2:
The vibration damping element is nested within the space defined by the first and second enveloping surfaces of the mount body. The enveloping surfaces partially encompass the vibration damping element, creating a nested configuration where the damping element is contained within the structural framework of the mount body.
