Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motor-gearbox connection structures are cumbersome and complex, leading to a long driver length and complicated installation processes due to separate motor and gearbox components.
Innovation Solution
A motor design that integrates a motor housing with a stator and rotor assembly, featuring a magnetic ring and output teeth on the rotor shaft, which are connected to the motor housing via a flange portion, allowing for a more compact and efficient connection with the gearbox.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the motor and gearbox are connected as separate components with threaded connection devices, then the connection is secure, but the driver length becomes too long and installation becomes complicated
Solution Approach 1:
The motor end cover is integrated with the flange plate to form a unified component. The flange plate is directly formed as an extension of the end cover, eliminating the need for separate threaded connection devices. This merging of components simplifies the overall structure, reduces installation complexity, and shortens the driver length while maintaining secure connection between motor and gearbox.
2Reliability
If separate motor and gearbox components are used with threaded connections, then the connection is reliable, but the driver length increases and installation cost increases
Solution Approach 1:
By integrating the flange plate directly into the motor end cover structure, the physical distance between motor and gearbox connection points is reduced. This eliminates intermediate connection elements and shortens the overall driver length while maintaining connection reliability through the rigid, integrated structure.
3Ease of manufacture
If separate motor and gearbox components are used, then the design is flexible, but the number of parts increases and manufacturing cost increases
Solution Approach 1:
The end cover and flange plate are merged into a single integrated component, reducing the total number of parts that need to be manufactured, inventoried, and assembled. This integration simplifies manufacturing processes, reduces part count, and lowers overall manufacturing costs while maintaining design flexibility.
