Hyperbolic Roller Lubrication for Continuous Rotor Straightening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing systems for straightening wire, rod, or re-bar using rotors with hyperbolic rollers face premature failure due to residue accumulation, which requires frequent lubrication and maintenance, leading to production interruptions and early replacement of rollers and bearings.
Innovation Solution
A system that uses a mixture of air and lubricant oil distributed through an oil-tight channel network to clean, protect, and lubricate the hyperbolic rollers and their bearings without stopping the rotor, ensuring continuous operation and automated control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If frequent lubrication is performed to prevent residue accumulation and premature failure, then reliability is improved, but productivity deteriorates due to production interruptions
Solution Approach 1:
The patent implements continuous lubrication of rollers and bearings during rotor operation without production interruption. The lubrication system operates concurrently with the straightening process, eliminating the need to stop production for maintenance and ensuring uninterrupted protective action against residue accumulation
Solution Approach 2:
The system enables self-service through automated lubrication where the rotor's own rotation drives the lubrication process. The rotating rotor pulls lubricant from the reservoir through channels to the rollers and bearings, and the same rotation enables residue removal through sealed channels, making the system self-sustaining without external intervention
2Reliability
If manual maintenance planning is implemented to service rollers and bearings, then reliability is improved, but device complexity increases and ease of operation deteriorates
Solution Approach 1:
The system transforms manual maintenance into automated self-service. The rotor's rotation automatically drives lubricant distribution through internal channels to rollers and bearings, and simultaneously enables residue ejection through sealed channels. This eliminates the need for operators to follow complex maintenance schedules and procedures
Solution Approach 2:
The patent replaces manual mechanical maintenance operations with an automated fluid-based system. Instead of manually applying lubricant and cleaning residues, the system uses lubricant flow carried by rotor rotation to automatically lubricate and clean components, substituting complex manual procedures with a simpler automated fluid delivery mechanism

Function Achieved in This Case
The system effectively prevents contamination, maintains clean bearings, and ensures smooth operation by continuously lubricating the rollers and bearings, reducing the need for frequent maintenance and extending their lifespan.
Implementation Method 1
A system for cleaning, protecting and lubricating with a mixture of air and lubricant oil the hyperbolic rollers and their respective bearings
Implementation Method 2

AI summary
The present invention refers to a system for cleaning, protecting and lubricating hyperbolic rollers and bearings, using air and oil, placed in a rotating rotor (1), which is used for straightening wire, rod or reinforcing bar, and contains rollers (32) placed on bearings (34) and shafts (33) inside roller housings (30), where rollers (32) are positioned at an angle with respect to the wire, rod or re-bar axis, they bend the wire, rod or re-bar, and as rotor (1) rotates around the wire, rod or re-bar longitudinal axis it straightens and feeds the wire, rod or re-bar, and where rollers (32) are placed on bearings (34) and are protected through rotational seals (35). The bearings' (34) area of rollers (32) inside the rotational seal (35) is supplied with air at pressure higher than the atmospheric, so that inflow of contaminants from the environment is inhibited, or is supplied with air enriched with oil so that bearings (34) are lubricated, and rotational seals (35) located next to bearings (34) of the rollers (32) allow the air flow from the area between the bearings towards the surrounding area.
