Sliding bearing lubrication form principle

Sliding bearing formation principle of sliding bearing lubrication lubricant is the necessary condition to form the lubrication film, static pressure bearing and dynamic pressure bearing is through the oil pump, economizer and oil groove to sliding bearing bush for oil forming oil film makes the bearing and shaft neck surface separately. Dynamic pressure of the sliding bearing oil film is to rely on the rotation of the shaft neck be brought into the lubricating oil bearing clearance, its oil supply method for oil supply and intermittent oil supply. The sliding bearing lubrication method can determine the type of credential coefficient k: p = F/( dB) - - The average pressure ( MPa） ； v - - Shaft neck line rate ( m/s） 。 k≤2- - In lubrication system, oil lubrication; k=2— 16 - - Needle valve type lubricating oil lubrication; k=16— 32 oil ring or splash lubrication; k≥32- - Pressure lubrication cycles.
