Coupling Attachment Layout for Flexible Driver Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional driver and driven device couplings are limited by the load capacity of the bearing, restricting the freedom of choice in selecting compatible drivers.
Innovation Solution
A driver attachment featuring a coupling with a hollow input shaft and a solid output shaft, supported by a bearing that handles both thrust and radial loads, allowing the solid rotating shaft of the driver to be fixed to the hollow input shaft and the solid output shaft to be inserted into the driven device.

Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional coupling structure is used to connect driver and driven device, then the bearing load capacity determines the system configuration, but the freedom of choice in selecting drivers is limited
Solution Approach 1:
The coupling is divided into two separate shafts: a hollow input shaft connected to the driver and a solid output shaft connected to the driven device. This segmentation allows independent optimization of each shaft for its specific function while maintaining reliable load transmission through the bearing support structure.
Solution Approach 2:
The hollow input shaft is designed to accommodate the solid rotating shaft of the driver within its hollow interior. This nesting arrangement allows the driver shaft to be positioned concentrically within the coupling structure, enabling flexible driver selection while maintaining proper alignment and load transmission through the bearing.
