Modular Geared Motor Arrangement with Central Housing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing geared motor arrangements are non-modular and cannot be compacted if one gear is removed, limiting space efficiency and flexibility in design and assembly.
Innovation Solution
A geared motor arrangement where two or more motors are attached to a central housing part with regularly spaced gears, allowing for modular design, axial force absorption, improved cooling, and easy gear changes, with a central housing part that includes a summation gear stage and radial motor placement for enhanced space utilization and assembly simplicity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If gears and summing wheel are accommodated in a common housing, then the structure is complete and functional, but the housing cannot be made smaller if one of the gears is omitted and the design is non-modular
Solution Approach 1:
The housing is divided into a central housing part and separate gear housing parts. Each gear can be individually attached to the central housing part via detachable connections, allowing gears to be added or removed independently without affecting the overall structure. This segmentation enables modular design where the housing can be adapted to different configurations (e.g., 2, 3, or 4 gears) while maintaining structural integrity.
2Power
If four motors are arranged in parallel with toothed parts on rotor shafts, then torque combination is achieved, but the arrangement is rigid and cannot be compacted when gears are omitted
Solution Approach 1:
The connection between the gear housing parts and the central housing part is made detachable rather than permanent. This dynamic connection allows the system to be reconfigured by attaching or detaching gear housing parts according to the required number of motors (2, 3, or 4), enabling flexible torque combination while adapting to different power requirements.
3Reliability
If the housing is designed to accommodate all gears, then complete functionality is ensured, but space efficiency is reduced when fewer gears are needed
Solution Approach 1:
The gear housing parts are designed to attach to the central housing part in a nested configuration. Each gear housing part contains its respective gear and motor assembly, which nests onto the central housing part. This nesting approach allows the housing volume to scale with the number of gears actually installed, rather than requiring space for all possible gears simultaneously.
