Method for Preserving a Machine Element and Use of an Ionic Liquid

Simple SummaryContent extracted from patent full text and abstract with AI.

The patent describes a method for preserving machine elements (such as bearings) by applying an ionic liquid to their surfaces after manufacturing and before installation or operation. This approach uses the unique properties of ionic liquids as preservatives to greatly increase the lifetime of these machine parts, particularly by preventing the early formation of 'White Etching Cracks' (WECs), a known failure mechanism in bearings made from steel alloys.

Use CasesContent extracted from patent full text and abstract with AI.

• Preservation of bearings for wind turbines before installation to extend operational life.
• Protection of steel machine elements in various industries (e.g., automotive, industrial machinery) during storage and transport.
• Enhancing the durability of components in power plants, including gearboxes and rotating assemblies.
• Use in aerospace or shipping industries where machinery is exposed to harsh environments before installation.

BenefitsContent extracted from patent full text and abstract with AI.

• Significantly increases the service life of machine elements by up to four times compared to traditional preservation methods.
• Prevents early failures caused by White Etching Cracks, reducing costly downtime and replacements.
• Requires only a small quantity of ionic liquid, reducing cost and minimizing potential toxicity or compatibility issues with lubricants.
• Compatible with standard lubricating oils and greases, allowing easy integration into existing processes.
• Reduces maintenance costs and risks during long storage or shipping periods of machine parts.
