Speed Reducer Support Shaft for Stable Power Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The connection between a drive shaft and a speed-reducing mechanism in existing technologies is unstable, leading to damage and unstable vehicle operation due to direct force transmission.
Innovation Solution
A speed reducer design that uses a support shaft to connect the drive member indirectly to the speed-reducing mechanism, dispersing forces and enhancing stability through a split-type transmission system, including primary and secondary speed-reducing components and a motor mounting base with cooling features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a drive shaft is directly connected to a speed-reducing mechanism, then the structure is simple, but the connection is unstable and the drive shaft is easily damaged
Solution Approach 1:
The patent introduces a support shaft as an intermediary component between the drive shaft and the speed-reducing mechanism. The support shaft is supported by the box body and connects to the high-speed end of the speed-reducing mechanism, acting as a mediator that stabilizes the connection and protects the drive shaft from direct force transmission.
2Power
If force is directly transmitted from the speed-reducing mechanism to the drive shaft, then the power transmission is direct, but the drive shaft is prone to damage from excessive force
Solution Approach 1:
The support shaft serves as a protective structure that cushions and disperses forces before they reach the drive shaft. By positioning the support shaft between the speed-reducing mechanism and the drive shaft, the system prepares for potential excessive forces in advance, preventing damage to the drive shaft while maintaining power transmission.
3Ease of operation
If the drive shaft is directly connected to the speed-reducing mechanism, then the connection is direct, but the vehicle operation becomes unstable
Solution Approach 1:
The support shaft acts as a stabilizing intermediary that improves vehicle operation stability. It is supported by the box body and connects to the speed-reducing mechanism, providing a stable connection point that reduces vibrations and instability during vehicle operation while maintaining operational efficiency.
