Motor Bearing Block Alignment via Dynamic Engagement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current motor assembly technologies face challenges in manufacturing efficiency, cost-effectiveness, and assembly complexity due to stringent tolerances and alignment requirements between bearing blocks and base bodies, particularly in engine assemblies that require frequent disassembly and reassembly.
Innovation Solution
The introduction of a counter-element area with a line or groove-like recess allows for a degree of freedom in the assembled state, enabling displacement of the bearing block relative to the base body, which reduces manufacturing accuracy demands and facilitates alignment, using engagement elements that form a non-positive connection upon assembly, allowing for precise alignment and easy reassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional rigid form-fitting connections are used between bearing block and base body, then alignment precision is improved, but manufacturing complexity and cost increase due to stringent tolerance requirements
Solution Approach 1:
The patent applies the dynamics principle by designing a connection that transitions from rigid to flexible. The deformation element (such as a resilient pin or elastic component) allows the bearing block to be mounted on the base body with intentional play, enabling dynamic adjustment during assembly. This eliminates the need for precise rigid tolerances while maintaining functional alignment through the deformation capability of the connection element.
2Manufacturing precision
If traditional rigid form-fitting connections are used between bearing block and base body, then alignment precision is improved, but assembly time and cost increase
Solution Approach 1:
The dynamic connection design allows for quick assembly by permitting the bearing block to be mounted with play on the base body. The deformation element absorbs misalignment automatically during assembly, eliminating the need for time-consuming precision adjustments or special alignment tools, thereby significantly improving assembly efficiency.
3Stability of the object's composition
If traditional rigid connections are used, then structural stability is improved, but ease of disassembly and reassembly deteriorates
Solution Approach 1:
The deformation element creates a connection that is stable during operation but easily disassembled when needed. The play and deformation capability allow the bearing block to be mounted and dismounted repeatedly without damage, facilitating maintenance and repair while maintaining structural integrity during normal use.
