What is lubrication and what is its purpose?
Lubrication is the process of using a lubricant to reduce friction and wear between two surfaces. Its purpose is to allow smooth operation of machine elements, reduce wear, and prevent damage and failure.
What is the study of lubrication called?
What is the study of lubrication called?
The study of lubrication is called tribology.
How do lubrication mechanisms like fluid-lubricated systems reduce friction and wear?
How do lubrication mechanisms like fluid-lubricated systems reduce friction and wear?
Fluid-lubricated systems reduce friction and wear by carrying the applied load through hydrodynamic or hydrostatic pressure, which reduces solid body interactions.

Study Notes
Overview of Lubrication
- Lubrication uses lubricants to diminish friction and wear between surfaces.
- It is a key concept within the field of tribology, which studies friction, wear, and lubrication.
- Different lubrication mechanisms exist, including fluid-lubricated systems that utilize hydrodynamic or hydrostatic pressure to minimize solid body interactions.
Importance of Adequate Lubrication
- Proper lubrication ensures smooth operation of machine elements, prolongs their lifespan, and lowers wear rates.
- It helps prevent excessive stresses and seizures in bearings, enhancing reliability in mechanical systems.
- When lubrication fails, components may contact directly, leading to destructive rubbing, heat generation, local welding, and significant component damage or failure.
Lubrication Mechanisms
- Fluid-lubricated systems adapt under varying loads on contacting surfaces.
- As load increases, unique operational scenarios arise, altering lubrication effectiveness and the degree of surface separation.
- Lubrication regimes vary based on surface interaction and separation, affecting performance and durability.
