Friction Mounting Ring With Helical Grease Channels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for lubricating ring, rotary, or slide-type articulations require dismounting components for manual lubrication, leading to delayed and costly maintenance, especially under load conditions where grease renewal is partial and uncontrolled.
Innovation Solution
The ring's bore is equipped with facilities that connect grease supply workings to all grease reserve workings, including those under load, using channels arranged in a helix to ensure continuous grease distribution without dismounting the articulation components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual lubrication is performed by dismounting components, then grease can be supplied to workings under load, but the operation becomes long, costly and involves disassembly risk
Solution Approach 1:
The grease supply system is segmented into multiple independent injection points distributed around the ring's circumference. Each injection point can supply grease to specific sectors of the bearing, allowing targeted lubrication of load zones without requiring complete disassembly. The helical channels further segment the grease distribution path to ensure coverage of all working surfaces including those under load.
Solution Approach 2:
The system enables self-service lubrication through automated or semi-automated grease injection mechanisms that can be operated without dismounting components. The grease injection system allows operators to replenish lubricant in-situ, transforming a complex disassembly task into a simple maintenance operation that can be performed while the articulation remains assembled and potentially in service.
2Quantity of substance
If grease is injected during standard lubrication, then workings away from load are resupplied, but workings under load receive only partial and uncontrolled grease renewal
Solution Approach 1:
The grease injection system incorporates locally adapted injection characteristics by positioning multiple injection points at different locations around the ring, with each point optimized to supply grease to specific zones. The helical channels are designed with varying geometry to control grease flow distribution, ensuring that load-bearing zones receive adequate lubricant quantity and quality tailored to their specific operational demands, rather than applying a uniform injection approach throughout.
Solution Approach 2:
The system incorporates feedback mechanisms through strategically placed injection points that monitor and respond to lubrication needs in different zones. The helical channel design provides feedback on grease distribution effectiveness, allowing adjustment of injection parameters to ensure proper lubrication of load zones. This enables controlled and monitored grease renewal in previously inaccessible areas.
3Duration of action of stationary object
If lubrication is delayed due to complex maintenance operations, then component operation deteriorates, but dismounting parts is required to perform proper lubrication
Solution Approach 1:
The grease injection system enables self-service lubrication that can be performed quickly without disassembling components. Operators can access injection points and replenish grease through simple operations, dramatically reducing maintenance time and allowing more frequent lubrication intervals. This transforms maintenance from a lengthy disassembly task into a rapid in-situ service operation.
Solution Approach 2:
The system incorporates preliminary action by pre-positioning multiple grease injection points and helical channels during manufacturing, so that lubrication pathways are already established and accessible. This preliminary configuration eliminates the need for complex assembly/disassembly operations during maintenance, allowing operators to simply inject grease through pre-prepared access points, thereby extending maintenance intervals through easier and more frequent service.
