Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rolling bearings in motors face issues due to assembly tolerance, leading to distortion, increased abrasion, and shortened lifespan when mounted, as the center axis alignment is challenging and heat dissipation is inefficient.
Innovation Solution
A rolling bearing design featuring an elastic mesh with through-holes surrounding the outer rim, allowing for easy axis alignment and rapid heat dissipation, where the outer rim is press-fitted into the elastic mesh, which is supported by a rolling bearing housing part, facilitating efficient heat transfer through the mesh's metal wire structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a rolling bearing is mounted in a motor with assembly tolerance, then the motor can be assembled, but the rolling bearing becomes distorted and experiences increased abrasion
Solution Approach 1:
The patent introduces an elastic mesh (thin film structure) surrounding the outer rim of the rolling bearing. This elastic mesh acts as a flexible protective layer that can deform to accommodate assembly tolerance while maintaining the bearing's functional integrity, thereby preventing distortion and reducing abrasion during operation.
Solution Approach 2:
The patent modifies the structural parameters of the rolling bearing by adding the elastic mesh with specific material properties (elasticity, porosity). This parameter change allows the bearing to adapt to assembly variations without compromising its reliability or increasing abrasion, resolving the contradiction between ease of assembly and bearing lifespan.
2Stability of the object's composition
If the rolling bearing is tightly mounted in the motor housing, then positional stability is improved, but heat dissipation becomes inefficient
Solution Approach 1:
The patent employs an elastic mesh with porous structure surrounding the outer rim. The porous nature of this mesh creates channels that facilitate heat transfer from the rolling bearing to the surrounding environment, improving heat dissipation efficiency while the elastic properties maintain center axis alignment stability.
Solution Approach 2:
The patent creates a composite structure by combining the rolling bearing with the elastic mesh material. This composite design integrates both structural support (for alignment stability) and thermal management (through the porous mesh's heat dissipation capabilities), resolving the contradiction between positional stability and heat dissipation.
3Ease of manufacture
If the rolling bearing structure is simplified for easy assembly, then manufacturing ease is improved, but heat dissipation capability deteriorates
Solution Approach 1:
The elastic mesh serves as a simple-to-install flexible shell that surrounds the rolling bearing. Its straightforward installation process maintains ease of manufacture, while its porous structure simultaneously provides effective heat dissipation pathways, preventing the deterioration of thermal management.
Solution Approach 2:
The elastic mesh performs multiple functions: it protects the bearing from distortion, facilitates heat dissipation, and maintains alignment stability. This multi-functional component achieves heat dissipation capability without complicating the assembly process, resolving the contradiction between manufacturing simplicity and thermal performance.
