Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional linear guideways face challenges in evenly distributing lubricating oil within rolling channels, affecting the smooth rolling of rollers.
Innovation Solution
The linear guideway incorporates a slider with circulation seats featuring turning segments and oil multi-channels, allowing for uniform distribution of lubricating oil through the rolling channels, and includes end caps for oil injection, ensuring smooth roller movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional linear guideway uses lubricating oil for roller rolling, then the rollers can roll smoothly, but the lubricating oil is not evenly distributed in the rolling channels
Solution Approach 1:
The circulation seat is divided into multiple segments including turning segments, outer rail segments, and inner rail segments. The turning segments are further divided into first and second turning segments with distinct functions. This segmentation allows for optimized oil flow paths and even distribution of lubricating oil throughout the rolling channels while maintaining smooth roller rolling.
Solution Approach 2:
The circulation seat acts as an intermediary component between the rollers and the rail, providing a structured pathway for lubricating oil distribution. The turning segments serve as intermediaries to redirect oil flow from the outer rail segments to the inner rail segments, ensuring even distribution across all rolling channels.
2Ease of manufacture
If the linear guideway structure is simplified, then the manufacturing cost decreases, but the lubrication distribution effectiveness worsens
Solution Approach 1:
The circulation seat performs multiple functions within a single integrated component: it guides roller movement, distributes lubricating oil through its segmented structure, and provides structural support. The turning segments simultaneously redirect oil flow and maintain the geometric precision of the rolling channel, achieving effective lubrication distribution without requiring additional separate components.
Solution Approach 2:
The patent combines the functions of oil distribution channels, roller guides, and structural support elements into a single circulation seat component. The turning segments integrate oil redirection functionality with the structural geometry of the rolling channel, reducing the number of separate parts while maintaining effective lubrication distribution.

AI summary
A linear guideway, a sliding module thereof, and a circulation seat thereof are provided. The circulation seat has two sliding channels and can be assembled to a slider. The circulation seat includes two turning segments, two outer rail segments, and two inner rail segments. Each of the two turning segments has a layout surface arranged adjacent to the slider and an oil multi-channel recessed in the layout surface and being in spatial communication with the two sliding channels. Two ends of each of the two outer rail segments are respectively connected to the two turning segments. Two ends of each of the two inner rail segments are respectively connected to the two turning segments. Each of the two outer rail segments is connected to one of the two inner rail segments through the two turning segments so as to jointly form one of the two sliding channels.
