Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing geared motor designs complicate motor replacement and environmental protection, as they require draining the cooling medium and lack visibility for damage detection, and they often require additional bearings and complex modifications for multi-motor setups.
Innovation Solution
A modular geared motor design with freely accessible motors, where each motor can be replaced individually without draining the cooling medium, featuring an adapter flange that integrates the summation gear and cooling medium management, allowing for easy alignment and lubrication, and utilizing existing motor shaft bearings to eliminate additional bearing needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If motors are arranged in motor mounts with cooling medium between them, then cooling is improved, but motor accessibility for replacement deteriorates and visibility for damage detection is lost
Solution Approach 1:
The drive system is segmented into modular components: multiple independent motor modules (20) that can be individually removed, a separate summation gear (30), and a housing (10) with integrated cooling channels. This segmentation allows motors to be accessed and replaced individually without affecting other motors or requiring draining of the cooling medium, as each motor has its own inlet (22) and outlet (24) connections to the cooling system.
2Stability of the object's composition
If motors are enclosed in motor mounts, then structural integration is improved, but visibility for damage detection deteriorates
Solution Approach 1:
The housing (10) serves multiple functions: it provides structural support, integrates the cooling medium distribution system with channels leading to each motor, and maintains structural integrity while allowing motor visibility. The housing acts as both a structural frame and a cooling system, eliminating the need for separate motor mounts while preserving accessibility and detectability.
3Reliability
If additional bearings are added for central wheel mounting, then rotational support is improved, but device complexity increases
Solution Approach 1:
The bearing functions are merged into the motor modules themselves. Each motor (20) contains bearings that support its rotor shaft, and these same bearings also support the pinions (28) that engage with the central wheel (32). The input shaft (34) of the summation gear is supported by bearings integrated into the housing structure, eliminating the need for separate dedicated bearings for the central wheel.
4Ease of repair
If motors are made freely accessible, then replacement ease is improved, but structural integration deteriorates
Solution Approach 1:
The system is divided into independently removable motor modules (20) that can be freely accessed from the outside. Each motor module is a self-contained unit with its own mounting interface to the housing, allowing individual removal and replacement without disassembling the entire drive system or affecting other motors, while the housing maintains overall structural integrity.

AI summary
The invention relates to a geared motor comprising electric motors, gears and an adapter which is disposed between the electric motors and the gears; the gears comprising an input shaft and an output shaft; each motor having a rotor shaft; the adapter having an adapter flange which forms a housing; the adapter flange at least partially surrounding a summarizing gear in such a manner as to form a housing, in particular for causing the power flows generated by the motors to converge at the gear input shaft; a cooling medium, in particular coolant, being able to flow through each of the motors, which are in particular liquid-cooled; the motors having an outlet for the cooling medium; there being formed on the adapter flange ducts which cause the cooling medium emerging at each motor outlet to converge at an outlet, in particular at a single common outlet on the adapter flange.
