Speed Reducing Device With Offset Mounting Flange
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing speed reducing devices lack versatility in mounting configurations, requiring additional costs and time to meet specific dimensional demands, as they are typically designed for fixed positional relationships between power connection and mounting portions.
Innovation Solution
A speed reducing device with an input shaft, speed reducing mechanism, and output members on both axial sides, featuring a mounting flange positioned away from the axial center, allowing for flexible orientation and positioning of the driving source and counterpart machine, enabling 180-degree rotation and adjustable distance between power connection and mounting portions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a general-purpose speed reducing device with fixed mounting configuration is used, then manufacturing cost is reduced, but adaptability to different mounting requirements deteriorates
Solution Approach 1:
The speed reducing device is designed with symmetric output members on both axial sides and spigot joint portions at multiple positions, enabling the same device to be mounted in various orientations (0 degrees, 90 degrees, 180 degrees) and configurations. This universal design allows a single general-purpose device to replace multiple dedicated devices, improving mounting adaptability without increasing manufacturing cost.
2Adaptability or versatility
If a dedicated speed reducing device is designed to meet specific dimensional requirements, then adaptability to specific needs is improved, but manufacturing cost and development time increase
Solution Approach 1:
The device incorporates adjustable and reconfigurable mounting elements, including spigot joint portions that can be positioned at different locations and output members that can be oriented in multiple directions. This dynamic configurability allows the same device to adapt to various dimensional requirements through repositioning and reorientation, eliminating the need for custom-designed dedicated devices for each application.
3Stability of the object's composition
If the mounting flange is positioned at the axial center of the casing, then structural symmetry is improved, but mounting flexibility deteriorates
Solution Approach 1:
The design intentionally positions the mounting flange away from the axial center of the casing, creating an asymmetric configuration. This asymmetric placement, combined with the provision of spigot joint portions at multiple positions, enables the device to achieve various mounting orientations and configurations, thereby improving mounting flexibility while maintaining overall structural balance through the symmetric arrangement of other components.
