The invention discloses a tilting-pad thrust bearing capable of detecting axial force of a rotating machine. The thrust bearing comprises a bearing body, a thrust disc, a tilting pad, a swing block, bearing trays and an end cover. The thrust disc, the tilting pad, the swing block and the bearing trays are installed in the bearing body and are locked and positioned by the end cover. The end face of each bearing tray is provided with multiple arc extrusion blocks. The extrusion blocks on the two bearing trays are in tight fit with the end cover and the bearing body correspondingly. The outer sides of the extrusion blocks are provided with a groove, and therefore a gap of 4-6 mm is formed between the extrusion blocks and the bearing trays. Working stress pieces are arranged on the inner sides of the extrusion blocks in a sticky mode. The structure is simple, and axial force can be accurately measured on line on the basis of not changing the assembly structure of the tilting-pad thrust bearing.
Description
technical field [0001] The invention relates to a device for detecting the axial force of a rotating machine, in particular to a tilting pad thrust bearing capable of detecting the axial force of a rotating machine. Background technique [0002] At present, large-scale rotating mechanical equipment such as centrifugal pumps, steam turbines, and compressors are developing towards large-scale and high-speed development, and their reliability issues are crucial. The magnitude and change trend of axial force are important parameters that affect their safe operation and predict their life. one. Since the axial force is difficult to accurately calculate through theoretical and empirical methods, accidents such as thrust bearing wear, damage, and spindle fracture occur from time to time. Only experimental methods can be used for actual measurement, and the online accurate measurement of the actual axial force of large equipment is of great help to the improvement. The safety of pr...
