Abstract

The invention discloses a steam turbine tilting pad supporting thrust combined bearing, and belongs to the field of bearing design. The steam turbine tilting pad supporting thrust combined bearing comprises a supporting bearing, thrust bearings and adjusting base plates. The supporting bearing is of a tilting pad structure. The thrust bearings are of a Kingsbury type improved structure with an oilspraying structure. The two thrust bearings are arranged at the two ends of the supporting bearing respectively. The two adjusting base plates are arranged between the supporting bearing and the thrust bearings respectively. The steam turbine tilting pad supporting thrust combined bearing is of a split structure and is provided with an oil inlet structure, the installation structure is good in stability, the machining difficulty is low, a tilting pad can be cooled, friction power consumption is small, vibration is gentle and regular, and the steam turbine tilting pad supporting thrust combined bearing is very suitable for being used for high-speed running equipment such as a steam turbine.

Description

technical field [0001] The invention relates to a tilting pad support thrust combination bearing of a steam turbine, in particular to the technical field of bearing design. Background technique [0002] In the process of modern production and assembly, the tilting pad radial bearing is often the preferred bearing for the high-speed rotor of the steam turbine. The tilting pad radial bearing is a bearing form with the best stability. It is usually composed of multiple pouring Babbitt alloy The tilting pad can automatically adjust the slope of the pad with the change of load and speed, forming multiple oil wedges and dynamic pressure oil films. The pad back of each pad is in line contact with the bearing body, and can be moved freely during work. Adjusting the oil film gap makes the tilting pad bearings have good vibration damping properties. They are mainly used in high-speed and light-load equipment such as steam turbines, compressors, turbine equipment, and pumps. The tiltin...
