Central Lubrication Telescopic Shaft Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing central lubrication systems for telescopic shafts are cumbersome to insert and require precise alignment for lubricant distribution, limiting flexibility and ease of use.
Innovation Solution
A lubricating device with a filling element, dispensing element, and lubricant channels that form a peripheral distribution channel with the inner profile tube, allowing lubricant to be supplied circumferentially and radially, enabling flexible alignment and easy insertion without disassembling the telescopic shaft.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional central lubrication systems are used, then lubrication function is provided, but insertion is cumbersome and alignment is complex
Solution Approach 1:
The lubricating device is divided into separate components: a filling element with filling channel, a dispensing element with dispensing channel, and connecting pieces. This segmentation allows each component to be independently positioned and inserted, simplifying the overall insertion process and reducing alignment complexity.
Solution Approach 2:
The connecting pieces are designed with universal connection capabilities that can accommodate multiple feeding positions and dispensing positions. The connecting pieces include multiple connection elements that can connect to different positions on the inner profile tube, providing flexibility and reducing the need for precise alignment during insertion.
2Adaptability or versatility
If multiple feed channels are provided, then lubrication coverage is improved, but alignment requirements increase
Solution Approach 1:
The system allows for dynamic selection of active feed channels and dispensing positions. Not all feed channels need to be aligned simultaneously; instead, the system can adapt to different operational requirements by activating specific channels, reducing the precision required for all channels to be perfectly aligned at once.
Solution Approach 2:
The connecting pieces act as intermediaries between the feed channels in the inner profile tube and the dispensing channels in the outer profile tube. These intermediaries provide tolerance compensation and position adjustment capabilities, allowing multiple feed channels to be connected without requiring precise alignment between all components.
