Linear Guide Lubrication Paths for Grease and Oil Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing guide devices face challenges in accommodating changes in lubricants, as the cross-sectional area required for grease and lubricating oil are significantly different, leading to inefficiencies and incomplete lubrication distribution when switching between the two.
Innovation Solution
The guide device incorporates a lubrication path with a common path and separate paths for grease and lubricating oil, allowing for adjustable cross-sectional areas and a plug member to control lubricant flow, enabling seamless switching between different lubricants.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single lubrication path is designed for grease (high viscosity), then grease can be supplied effectively, but lubricating oil (low viscosity) cannot be supplied properly due to excessive path volume
Solution Approach 1:
The lubrication path is segmented into multiple separate paths (first lubrication path for grease, second lubrication path for lubricating oil) with different cross-sectional areas. Each path is optimized for its specific lubricant type, allowing both grease and lubricating oil to be supplied effectively without compromise.
Solution Approach 2:
The lubrication system is made dynamically configurable through a plug member that can be positioned at different locations within the common path. By moving the plug member, the system can selectively block either the first or second lubrication path, enabling flexible switching between grease and lubricating oil supply modes after installation.
2Ease of operation
If the lubrication path cross-sectional area is made large for grease, then grease supply is improved, but lubricating oil distribution becomes incomplete due to excessive volume
Solution Approach 1:
The lubrication path is divided into separate segments: a first lubrication path with larger cross-sectional area optimized for grease supply, and a second lubrication path with smaller cross-sectional area optimized for lubricating oil distribution. This segmentation allows each path to be precisely designed for its specific lubricant requirements.
Solution Approach 2:
Different sections of the lubrication system are given different local qualities - the first path has larger cross-sectional area for grease flow, while the second path has smaller cross-sectional area for precise lubricating oil distribution. This local differentiation optimizes performance for each lubricant type.
3Productivity
If a small lubrication path is designed for lubricating oil, then lubricating oil supply is efficient, but grease cannot enter due to insufficient path cross-sectional area
Solution Approach 1:
The lubrication system is segmented into two distinct paths: a second lubrication path with small cross-sectional area for efficient lubricating oil supply, and a first lubrication path with large cross-sectional area for reliable grease supply. This ensures both lubricant types can be supplied effectively through their respective optimized paths.
Solution Approach 2:
The common path serves as a universal entry point for both grease and lubricating oil, while the subsequent segmentation into first and second paths provides specialized channels for each lubricant type. This multi-functional design allows the system to handle different lubricant requirements.
4Reliability
If the lubrication path structure is changed according to the lubricant type, then optimal lubrication is achieved, but the structure becomes difficult to adjust after installation
Solution Approach 1:
The lubrication system incorporates a movable plug member that can be dynamically repositioned within the common path to selectively block either the first or second lubrication path. This dynamic configuration allows the system to be optimized for different lubricant types even after installation, maintaining both reliability and ease of adjustment.
Solution Approach 2:
The system allows users to self-adjust the lubrication path configuration by simply moving or removing the plug member according to the lubricant type being used. This eliminates the need for complex structural changes or professional service intervention when switching between grease and lubricating oil.

Function Achieved in This Case
This solution allows for efficient lubrication distribution regardless of the lubricant used, reducing wear and extending the lifespan of the guide device, while also enabling easy changes in lubricant after installation.
Implementation Method 1
there is a great difference in viscosity between grease and lubricating oil. Specifically, the viscosity of grease is higher than that of lubricating oil.

AI summary
A guide device includes a track member and a moving member with rolling elements interposed therebetween. A lubricating path is formed in the moving member for supplying lubricant to a circulation path for the rolling elements. The lubricating path has a common path including an inlet portion that serves as a supply port for the lubricant, a first path through which grease flows, and a second path through which lubricating oil flows. A cross-sectional area of the second path is smaller than a cross-sectional area of the first path, and in the common path, a second communication portion of the second path is located closer to the inlet portion than a first communication portion of the first path. Further, the guide device includes a plug member for blocking the inlet portion of the common path, the plug member being removable and able to be moved within the common path.
