Lubricant Bath Structure With Level Check Hole for Robot Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lubricant bath structures in robots lack efficient mechanisms for minimizing lubricant discharge during maintenance, leading to excessive lubricant usage and prolonged maintenance times, especially in large robots.
Innovation Solution
A lubricant bath structure with a casing that includes a supply hole, a discharge hole, a liquid level check hole, and a part attachment hole, where the liquid level check hole is positioned to confirm the lubricant level has reached below the part attachment hole, allowing for controlled lubricant discharge and recharging, thereby minimizing lubricant loss and reducing maintenance time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If the discharge hole is used to discharge lubricant during maintenance, then the lubricant can be discharged from the casing, but a large amount of lubricant is discharged excessively and maintenance time is prolonged
Solution Approach 1:
The discharge function is segmented into two separate holes: the discharge hole for complete drainage and the liquid level check hole for controlled discharge. This segmentation allows selective use of each hole based on maintenance needs, preventing excessive lubricant loss while reducing maintenance time through efficient drainage when needed.
Solution Approach 2:
The liquid level check hole acts as an intermediary element that enables controlled lubricant discharge. By providing a separate check hole with a stopper, the system allows precise control over discharge amount, preventing the excessive discharge that would occur through the main discharge hole while still enabling maintenance operations.
2Measurement precision
If the liquid level check hole is positioned at the lower edge of the part attachment hole, then the lubricant level can be accurately confirmed, but the structure becomes more complex
Solution Approach 1:
The liquid level check hole is merged with the existing casing structure rather than being a separate external device. By positioning it at the lower edge of the part attachment hole and using the same casing material and manufacturing process, the measurement function is integrated into the existing structure, minimizing additional complexity while achieving accurate lubricant level measurement.

Function Achieved in This Case
The solution effectively reduces the amount of lubricant discharged during maintenance, shortens maintenance time, and improves operational efficiency by ensuring accurate lubricant levels and preventing excessive lubricant flow.
Implementation Method 1
during discharge of the lubricant, it is possible to confirm that a liquid level of the lubricant has reached below the lower edge of the part attachment hole

AI summary
A lubricant bath structure includes a casing for storing a liquid lubricant, where: the casing is provided with a supply hole, a discharge hole, a part attachment hole, and a liquid level check hole that penetrate from inside to outside of the casing; the supply hole enables injecting the lubricant into the casing; the discharge hole enables discharging the lubricant in the casing; the part attachment hole is opened/closed by detaching/attaching a mechanism part that is to be detachably attached to an outside surface of the casing; and the liquid level check hole can be arranged at a position coincident with or lower than a lower edge of the part attachment hole, but higher than the discharge hole, and, during the discharge of the lubricant, it is possible to confirm that a liquid level of the lubricant has reached below the lower edge of the part attachment hole.
