Different systems of direct oil supply have been developed in order to facilitate efficient introduction of fresh lubricant to the oil gap\r\nand reduction of churning power loss in tilting pad thrust bearings. Up to now there is no documented application of the supply\r\ngroove in large thrust bearings used in water power plants. ?e results of modeling lubricant ??ow in the lubricating groove of a\r\nthrust bearing pad will be presented in the paper. C??D so?ware was used to carry out ??uid ??lm calculations. Such analysis makes it\r\npossible to modify groove geometry and other parameters and to study their in??uence on bearing performance. According to the\r\nresults a remarkable decrease in total power loss due to avoiding churning losses can be observed in the bearing.
