2. Lubrication Systems of Large Tilting Pad Thrust Bearings 2.1. Bath Lubrication with Internal or External Cooling Systems Usual methods of lubrication of large thrust bearings did not change much since they were first invented—in vertical shaft machines, it is natural to arrange a bath lubrication with the pads immersed in oil.

Different systems of direct oil supply have been developed in order to facilitate efficient introduction of fresh lubricant to the oil gap and reduction of churning power loss in tilting pad thrust bearings. Up to now there is no documented application of the supply groove in large thrust bearings used in water power plants. The results of modeling lubricant flow in the lubricating groove of a ...
