Spindle Coupling Casing With Adjustable Seals for Lubricant Recovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lubricant recovery and protection systems for spindle couplings in rolling mills fail to effectively manage lubricant loss and protection from external agents, especially in reversible rolling mills where the distance between working rolls varies, leading to inefficient use and disposal of lubricants.
Innovation Solution
A lubricant recovery and protection system comprising a casing that houses the couplings and allows for variable height adjustments of spindles and working rolls, with deformable elements for airtight sealing and movable wall elements to accommodate changing distances, enabling the recovery and reuse of lubricants while protecting them from dust and water.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a fixed protection system is used for spindle couplings, then protection from external agents is improved, but adaptability to variable distances between working rolls deteriorates
Solution Approach 1:
The protection system employs movable wall elements that can dynamically adjust their position to accommodate variable distances between working rolls while maintaining continuous protection of spindle couplings. The wall elements are guided to move in a controlled manner, ensuring adaptability without compromising protection effectiveness.
Solution Approach 2:
The system utilizes deformable sealing elements that can flex and deform to maintain airtight sealing between the movable wall elements and the casing. These flexible sealing components allow the structure to adapt to distance variations while preserving the protective barrier against external agents.
2Adaptability or versatility
If movable wall elements are introduced for adaptability, then adaptability to variable distances is improved, but airtight sealing deteriorates
Solution Approach 1:
Deformable sealing elements are positioned between the movable wall elements and the fixed casing structure. These flexible sealing components can deform to accommodate the movement of wall elements while maintaining continuous airtight contact, preventing ingress of external agents despite the dynamic configuration changes.
3Duration of action of stationary object
If continuous lubrication is implemented, then component life is improved, but lubricant loss and disposal costs worsen
Solution Approach 1:
The protection system creates an enclosed environment that captures and retains lubricant within the coupling protection space. By preventing lubricant escape to the external environment, the system enables recovery and reuse of lubricant, eliminating disposal costs while maintaining continuous lubrication for extended component life.

AI summary
The invention relates to a lubricant recovery and protection system for spindle couplings (111a, 111b) for reversible roller stands which comprises at least two couplings arranged one above the other which connect each a spindle (114a, 114b) and a working roll and define between them a distance (118); and a casing (120) wherein said spindles and said working rolls can rotate and wherein in two opposite walls of the casing apertures are provided for the passage of the respective parts of the connecting unit. The walls of the casing contain wall elements (122a, 122b, 122c, 122d) containing said apertures adjustable in height and preferably deformable elements to achieve the distance variation under hermetic protection. Methods for recovery of the lubricant and for protection of spindle couplings in case of distance variation, a respective roller stand, a respective rolling mill train and a protective casing are described, too.
