Linear Guideway Changeable Oil-Storage Unit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing linear guideways face issues with short-lasting self-lubrication due to limited oil storage in oil-bearing materials and fixed oil-storage units, which are difficult to assemble and disassemble, leading to premature wear and tear.
Innovation Solution
A linear guideway design featuring a changeable oil-storage unit with an oil filler hole, joint unit, and connecting portions that allow for quick assembly and disassembly, forming an oil route for continuous lubrication, and using ultrasonic welding, thermofusion welding, or gluing methods for integration, along with sealing mechanisms to prevent oil leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an oil-bearing material or fixed oil-storage unit is used, then the linear guideway can be lubricated automatically, but the lubrication effect does not last for a long time due to limited oil storage capacity
Solution Approach 1:
The oil storage system is segmented into a permanent oil storage unit (integrated with the sliding block) and a removable oil storage unit (can be replaced). This segmentation allows the system to maintain continuous lubrication capability while enabling periodic replenishment of oil supply, thereby extending the overall lubrication duration beyond the limitations of fixed storage capacity.
2Reliability
If the oil-storage unit is fixed to the sliding block by screwing method, then the unit is securely attached, but it is time-consuming and difficult to assemble and disassemble
Solution Approach 1:
The connection mechanism transitions from a static screwed connection to a dynamic snap-fit connection. The connecting portion features a resilient arm that can elastically deform during assembly, allowing the oil-storage unit to be snapped into place without threads. This dynamic connection maintains secure attachment during operation while enabling rapid assembly and disassembly by simply pressing the release structure.
3Ease of operation
If a removable oil-storage unit is designed for easy replacement, then assembly and disassembly become quick and easy, but the connection reliability may be compromised
Solution Approach 1:
The connection mechanism employs a composite structure combining a resilient arm (providing elastic deformation capability) with a snap-fit engagement feature. The resilient arm is made of elastic material that allows reversible deformation during assembly and disassembly, while the snap-fit structure provides positive mechanical engagement. This composite approach ensures both easy operation and reliable connection during the operational phase.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables long-lasting automatic self-lubrication, extending the service life of the linear guideway by allowing easy replacement of the oil-storage unit and preventing oil leakage, thus maintaining consistent lubrication.
Implementation Method 1
one of the connecting portions is provided with a resilient arm having an elastic action for elastically deforming, so as to snap-fit connect to the other of the connecting portions
Implementation Method 2
in the oil-storage space is defined an oil feeding hole... the oil is replenished... providing a long lasting automatic self-lubrication function

AI summary
A linear guideway with a changeable oil-storage unit comprises: a rail, a sliding block; an end cap having an oil-filler hole fixed to either end of the sliding block, an oil-storage unit having an oil storage space, a connecting portion, and an oil feeding hole; a joint unit defined with a through hole, and two connecting portions connected to the oil filler hole and the connecting portion of the oil-storage unit, respectively. One of the connecting portions has a plug-in arrangement for providing quick connection to the oil-storage unit, the through hole, the oil filler hole and the oil feeding hole are connected to one other, forming an oil route for providing lubrication for the linear guideway.
