Self-lubricating Guide Member with Groove Reserves
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing self-lubricating joints and bearings in high-load, abrasive, and corrosive environments face challenges in maintaining permanent lubrication, as grease or lubricants tend to escape, requiring frequent re-lubrication and inadequate wear resistance.
Innovation Solution
A self-lubricating guide member with a bore featuring channels and oriented grooves that act as a lubricant reserve, preventing lubricant escape and facilitating resupply, where the channels are positioned to prevent lubricant expulsion and the grooves communicate with the channels to maintain lubrication within the friction zone.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If grease reserve arrangements are implemented in the bore, then lubrication duration is improved, but lubricant escape prevention becomes problematic
Solution Approach 1:
The bore is segmented into multiple functional zones: retention zones (channels) at the ends and a distribution zone (grooves) in the middle. This segmentation allows different parts of the bore to perform different functions - preventing escape at the ends while enabling lubricant distribution in the friction zone.
Solution Approach 2:
Different regions of the bore are given different structural qualities. The channels at the ends have depth and configuration optimized for lubricant retention, while the grooves in the middle are oriented to facilitate lubricant distribution. Each zone's geometry is locally optimized for its specific function.
2Loss of time
If lubrication frequencies are reduced, then maintenance costs are improved, but lubricant escape increases
Solution Approach 1:
The channels are positioned at the ends of the bore to preliminarily retain lubricant before it can escape. This preliminary retention action prevents lubricant loss during operation, extending the time between maintenance interventions.
3Duration of action of stationary object
If wear resistance is improved, then component life is improved, but manufacturing complexity increases
Solution Approach 1:
The bore structure utilizes a controlled porous-like geometry with channels and grooves that create multiple retention and distribution points. This porous-like structure increases surface area for lubricant retention and distribution, enhancing wear resistance while the geometry can be manufactured using standard machining processes.
