Antifriction Properties of Lubricants and Their Effect on the Viscosity of Oils
Keywords:
friction, viscosity, power, wear, mechanical energy, antifriction propertiesAbstract
In this paper, the antifriction properties of lubricants and their effect on friction forces are considered. The antifriction properties of oils are understood as their ability to reduce the cost of mechanical energy for external friction. The loss of friction energy in a modern piston engine from the indicator power is 6-8% in the cylinder piston group, and 1-2% in bearings. With an increase in the viscosity of the oil, the hydraulic resistance increases, as a result of which the power costs for the oil pump drive increase, the supply decreases and the oil does not flow well to the friction units lubricated under pressure.References
