Abstract

The invention provides a tilting-pad thrust bearing device automatically adjusting oil film thickness. The device comprises a runner plate, pads, a base, threaded holes, resistance strain-gauge transducers, resistance-voltage converters, analog-digital converters, controllers, high-pressure oil nozzles and gaskets on the high-pressure oil nozzles. By means of the resistance strain-gauge transducers, the resistance-voltage converters and the analog-digital converters, the deformation amount of the current pad can be converted into a numerical value, then, the controller is used for judging whether the corresponding high-pressure oil nozzle is needed to spray oil to the pad or not, and then the oil film thickness of the pad is changed. The tilting-pad thrust bearing device is simple in structure, the unbalance loading problem of a tilting-pad thrust bearing can be quickly found and solved only by additionally arranging a set of control systems and high-pressure oil nozzles based on a mechanical structure of the original tilting-pad thrust bearing, and the service life of the tilting-pad thrust bearing is prolonged to a great extent.

Description

technical field [0001] The invention relates to the technical field of bearing devices, in particular to a tilting pad thrust bearing device that automatically adjusts the thickness of an oil film. Background technique [0002] At present, each tile in the tilting pad thrust bearing can rotate around its own fulcrum, which can well adapt to changes in working conditions, and is widely used in turbine steam turbine units to bear axial force. However, due to processing and installation errors and deformation of the mirror plate and tiles during use, the oil film thickness of a certain tile will be smaller than that of other tiles, and the load on this tile will also be smaller. Large, if the bearing is in this working environment for a long time, it will definitely cause equipment damage and increase the maintenance cost. Therefore, a tilting pad thrust bearing device is needed to solve this problem. Contents of the invention [0003] The invention provides a tilting pad th...
