Hydrodynamic Lubrication:
- It is thick film lubrication in which fluid pressure is created by the relative motion between the moving parts.
- As fluid pressure is itself being created, there is no need for a pressurized supply of lubricant.
- In this, surfaces do not contact during the rotation as there is a thick film of the lubricant.
- It can be used with thrust as well as sliding contact bearing.
Hydrostatic lubrication:
- In hydrostatic lubrication, external pressure is supplied to separate two surfaces, while relative velocity between two surfaces is used to generate liquid pressure between two surfaces.
- Hydrostatic lubrication is generally costlier compared to hydrodynamic lubrication.
- In hydrostatic lubrication, the pump is used.
- Thick film lubrication is further divided into two groups
- Hydrodynamic lubrication
- Hydrostatic lubrication
