öljylubrikoinnissa

Öljylubrikoinnissa, commonly known in English as oil lubrication, is a method used to reduce friction between moving parts in machinery. It involves applying a lubricant, typically oil, to surfaces that are in contact to create a thin film. This film separates the surfaces, preventing direct metal-to-metal contact and thus minimizing wear and heat generation.

The principle behind oil lubrication is hydrodynamic lubrication. As the machine parts move, the oil is drawn into the converging gap between them, creating a pressurized film that can support the load. This process requires a specific viscosity of oil that is appropriate for the operating temperature and pressure of the machine. Too thin an oil might not provide sufficient film strength, while too thick an oil can increase drag and energy loss.

Oil lubrication is widely used in various applications, including engines, gearboxes, bearings, and hydraulic systems. Its effectiveness depends on factors such as the type of oil used, the cleanliness of the oil, and the design of the lubricated components. Regular maintenance, including oil changes and filtration, is crucial to ensure the continued effectiveness of oil lubrication and to prolong the lifespan of machinery. Contamination of the oil with debris or water can significantly degrade its lubricating properties and lead to premature wear.
