Linear Guide Lubrication Channel for Roller Bearing Circulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing linear guide devices face challenges in simple and cost-effective lubrication of roller bearing elements, which affects their performance and longevity.
Innovation Solution
Incorporating a single-piece housing intermediate element with integrated pipe-stub-like lubrication appendices that allow for external lubricant access and distribution directly into the circulating channels, eliminating the need for separate lubrication assembly and ensuring uniform lubricant delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a separate lubrication assembly is used, then lubrication function is achieved, but device complexity increases and manufacturing cost rises
Solution Approach 1:
The lubrication appendix is integrally formed as part of the housing intermediate element, combining the lubrication function with the structural housing component. This eliminates the need for separate lubrication assemblies and reduces both manufacturing steps and assembly complexity while maintaining effective lubrication delivery to the circulating channels
2Ease of operation
If lubrication access is provided from outside, then lubrication ease is improved, but housing structure complexity increases
Solution Approach 1:
The lubrication appendix is pre-integrated into the housing intermediate element during manufacturing, with the lubrication opening positioned on the outer surface for direct external access. This preliminary integration eliminates the need for complex internal lubrication pathways while maintaining simple external access for lubrication maintenance

Function Achieved in This Case
Facilitates easy and inexpensive lubrication of roller bearing elements, enhancing their movement efficiency and reducing wear, while maintaining a compact and cost-effective construction.
Implementation Method 1
at least one lubrication channel which communicates with the circulating channels passing through the single-piece housing intermediate element of the guide housing of the linear guide unit and extends partly also in an integral pipe-stub-like lubrication appendix of the single-piece housing intermediate element, said lubrication appendix comprising a lubrication opening which is accessible from outside the guide housing for bringing in lubricant

AI summary
A linear guide device includes at least one linear guide unit which has a guide housing, in which two annularly closed circulating channels are formed in each of which a multitude of roller bearing elements is received. The guide housing has a single-piece housing intermediate element which contributes to the formation of the circulating channels and through which passes at least one lubrication channel which communicates with the circulating channels. The lubrication channel passes through the single-piece housing intermediate element and extends partly also in an integral pipe-stub-like lubrication appendix of the single-piece housing intermediate element, wherein the lubrication appendix includes a lubrication opening which is accessible from outside the guide housing for bringing in lubricant.
