Elastic Protection Casing for Rotor Radial Impact
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rotation structures in existing machine apparatuses are prone to radial impact damage, corrosion, and excessive noise due to the lack of protection, which shortens their service life and affects performance.
Innovation Solution
A rotation structure with an elastic protection casing that surrounds the rotor, providing radial impact absorption, corrosion protection, and noise reduction through elastic deformation and enhanced friction capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the periphery of the rotation structure is provided with no protection structure, then the structure is simple and easy to manufacture, but the periphery is subjected to great radial impact and may be damaged
Solution Approach 1:
The patent applies an elastic protection casing that envelops the periphery of the rotor. This flexible shell structure absorbs radial impacts through elastic deformation while maintaining structural simplicity. The casing is configured to elastically deform under impact loads and recover, protecting the rotor without requiring complex rigid protection mechanisms.
Solution Approach 2:
The elastic protection casing serves as a pre-installed cushioning layer between external impact sources and the rotor. It is designed to absorb and dissipate radial impact energy before it can reach the rotor, thereby preventing damage in advance while keeping the overall structure simple.
2Reliability
If the periphery of the rotation structure is provided with no protection structure, then the structure is simple, but the rotation structure is prone to be wetted and corroded
Solution Approach 1:
The elastic protection casing acts as a protective barrier that prevents corrosive substances (liquids and gases) from directly contacting the rotor periphery. This flexible shell provides corrosion protection while maintaining structural simplicity and allowing for elastic deformation during operation.
3Object-generated harmful factors
If the rotation structure has no protection structure, then the structure is simple, but the rotation structure generates too much noise
Solution Approach 1:
The elastic protection casing serves as a noise reduction barrier that surrounds the rotor periphery. The elastic material absorbs and dampens vibration-induced noise while allowing the structure to remain relatively simple. The casing flexes with the rotor motion, reducing noise transmission to the surrounding environment.

Function Achieved in This Case
The elastic protection casing extends the service life of rotation structures by reducing radial impacts and noise, while enhancing friction and corrosion resistance, making them suitable for high-performance applications.
Implementation Method 1
The elastic protection casing has the elastic deformation effect, when the rotation structure transmits power to other structures or devices, the elastic protection casing can reduce radial impacts of external forces onto the rotor
Implementation Method 2
the elastic protection casing can absorb most noise generated by the rotation structure
