Linear Guide Lubrication Path for Grease and Oil Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing linear guide rail lubricant supply structures face challenges in designing a single lubricant supply path that optimally accommodates both lubricating grease and lubricating oil, as the required cross-sectional area and length of the lubricant supply path differ significantly between the two lubricants, making it difficult to achieve effective lubrication for both.
Innovation Solution
The motion guiding device incorporates a lubrication path component with a first lubrication groove for lubricating grease and a second lubrication groove with a smaller cross-sectional area, allowing for adjustable lubricant supply paths by using a fitting portion and insertion portion to accommodate either lubricating grease or lubricating oil, ensuring optimal lubrication for both types of lubricants.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the cross-sectional area of the lubricant supply path is increased to accommodate lubricating grease, then lubricating grease lubrication is improved, but the lubricant supply path becomes too large for lubricating oil lubrication
Solution Approach 1:
The lubricant supply path structure is made changeable through the detachable insertion portion that can be inserted or removed. When lubricating grease is used, the insertion portion is removed to provide a large cross-sectional area. When lubricating oil is used, the insertion portion is inserted to reduce the cross-sectional area. This dynamic reconfiguration allows the same base structure to adapt to different lubrication requirements.
Solution Approach 2:
The lubricant supply path is segmented into a fixed base structure (first lubrication groove) and a detachable insertion portion (second lubrication groove). This segmentation allows the insertion portion to be selectively added or removed to change the overall cross-sectional area of the lubricant supply path, enabling adaptation between grease and oil lubrication modes.
2Reliability
If the length of the lubricant supply path is reduced to improve lubricating grease lubrication, then lubricating grease lubrication is improved, but the lubricant supply path structure becomes insufficient for lubricating oil lubrication
Solution Approach 1:
The lubricant supply path length is made dynamically adjustable through the detachable insertion portion. The first lubrication groove provides a base length optimized for grease lubrication. The second lubrication groove (insertion portion) can be inserted to extend or modify the path length when lubricating oil is used, allowing optimization for different lubricant types.
3Adaptability or versatility
If a single lubricant supply path is designed to accommodate both lubricating grease and lubricating oil, then versatility is improved, but lubrication performance for both lubricants deteriorates
Solution Approach 1:
Rather than designing a single fixed path that compromises both lubricants, the invention creates a dynamic system where the lubricant supply path configuration changes based on the lubricant type. The insertion portion is removed for grease lubrication and inserted for oil lubrication, allowing each lubricant to have an optimized path configuration and achieving high lubrication performance for both.
Solution Approach 2:
The lubricant supply path is divided into modular segments (first and second lubrication grooves) that can be selectively combined. This segmentation enables the system to achieve optimal lubrication performance for both grease and oil by configuring the appropriate segment arrangement for each lubricant type.

AI summary
A motion guiding device includes a supporting body and a moving body. The moving body includes a moving body main body, a cover body and a circulation component. The cover body includes a first lubrication groove. The motion guiding device is further provided with a lubrication path component, the lubrication path component including a second lubrication groove having a cross-sectional area less than that of the first lubrication groove. When a lubricating oil is used as the lubricant, the lubricant is supplied by a lubricating oil lubrication path formed by the first lubrication groove and the second lubrication groove. In this way, in the motion guiding device, the lubrication path may be widened when the lubricating grease is used to lubricate, while the lubrication path may be narrowed when the lubricating oil is used to lubricate, so that a good lubrication may be easily achieved.
