Radially Movable Transmission Outer Ring for Self-Centering Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional gearbox installations require strict alignment tolerances to ensure a long service life, which is complex and often not feasible, leading to reduced service life due to positional and angular deviations within permissible tolerance ranges.
Innovation Solution
The toothed section of the gearbox outer ring is connected to the fastening section in a radially movable manner, allowing self-centering during operation, reducing wear on components and extending service life, even with less stringent installation tolerances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the transmission outer ring is rigidly fastened to the structure, then the alignment precision is improved, but the installation complexity and tolerance requirements increase significantly
Solution Approach 1:
The patent applies the dynamics principle by making the connection between the transmission outer ring and the structure movable rather than rigid. The fastening section is designed with degrees of freedom that allow automatic adjustment and self-centering during operation, eliminating the need for precise pre-alignment while maintaining operational precision.
2Duration of action of stationary object
If strict alignment tolerances are enforced during installation, then the service life is extended, but the installation time and complexity increase
Solution Approach 1:
The patent implements self-service through the self-centering mechanism of the fastening section. The transmission outer ring automatically adjusts its own position relative to the structure during operation, eliminating the need for external alignment procedures and precision installation tools, thereby reducing installation time while ensuring long service life.
3Stability of the object's composition
If the toothed section is rigidly connected to the fastening section, then the structural stability is improved, but the load on transmission components increases due to misalignment
Solution Approach 1:
The patent resolves this contradiction by introducing controlled mobility to the connection between the toothed section and fastening section. The fastening section allows radial movement while maintaining rotational stability, enabling the transmission outer ring to self-center and reduce misalignment loads while preserving structural stability during operation.
