How is the lubricating oil film in bearings formed?

Reply #22009-04-07

Due to the adsorption force between the shaft and the oil, the rotation of the shaft causes the oil to form an oil film

To be precise, it is the journal that rotates within the bearing hole, and the lubricating oil creates an oil film between the journal and the bearing bush to reduce friction and wear. The principle involves using the rotation of the shaft itself to drive the lubricating oil in the bearing from areas with larger gaps to those with smaller gaps, thereby forming a wedge-shaped oil wedge. This process generates oil pressure that balances the loads on the shaft journals, allowing the shaft journals to be separated from the inner walls of the bearings and creating an oil film that keeps the shaft and bearings in a state of fluid friction.
