Segmented Adapter Assembly for Symmetric Stator Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional adapters used in railway freight wagons for mounting axle-end generators result in asymmetric stator support, leading to vibration and potential damage due to inadequate mounting stability.
Innovation Solution
An adapter assembly with a partition structure comprising a first and second part, connected via screws or other fasteners, providing symmetric mounting points for the stator on both parts to ensure stable installation of the axle-end generator.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional adapter is used to mount the stator, then the generator can be installed on wagon bogies without axle boxes, but the stator support becomes asymmetric leading to vibration and potential damage
Solution Approach 1:
The adapter is divided into a first part and a second part that are connected together. The first part is mounted on the wagon bogie while the second part provides additional support for the stator. This segmentation allows the adapter to achieve symmetric stator support (improving stability) while maintaining the ability to install the generator on wagon bogies without axle boxes (maintaining adaptability).
Solution Approach 2:
The first part and second part of the adapter are combined to form a unified mounting structure. The first part connects to the wagon bogie and the second part connects to the stator, creating a merged structure that provides both the adaptability to mount on bogies without axle boxes and the symmetric support needed for stator stability.
2Ease of manufacture
If a conventional adapter with single-side support is used, then the installation is simplified, but the asymmetric mounting structure causes vibration and drifting of the stator
Solution Approach 1:
By dividing the adapter into two parts with different functions (first part for bogie mounting, second part for stator support), the structure achieves symmetric support that prevents stator vibration and drifting, thereby improving reliability while maintaining relatively simple installation procedures.
Solution Approach 2:
The first part of the adapter is designed for mounting on the wagon bogie with appropriate connection features, while the second part is designed specifically to provide symmetric support for the stator. This local differentiation of structural qualities allows each part to optimize its function, achieving both ease of installation and operational reliability.
3Adaptability or versatility
If the stator is mounted on a conventional adapter, then the generator can operate on wagon bogies, but the asymmetric support structure results in inevitable vibration and drifting
Solution Approach 1:
The adapter is segmented into a first part for bogie adaptation and a second part for stator support. This segmentation enables the generator to operate on wagon bogies (maintaining adaptability) while the second part provides symmetric support that eliminates stator vibration and drifting (improving ease of operation).
Solution Approach 2:
The first and second parts of the adapter are merged into a single integrated structure that simultaneously provides adaptation to wagon bogies and symmetric support for the stator. This merging ensures both adaptability and operational stability are achieved together rather than as separate compromises.
