Thrust bearing

Abstract

The invention relates to a thrust bearing and belongs to the technical field of bearing lubrication. The thrust bearing comprises a bearing seat, a thrust pad and a balance part. A storing cavity for storing the thrust pad is formed in the bearing seat, and the thrust pad and the balance part are detachably installed in the bearing seat in an embedded mode; and the thrust pad comprises a graphite flake with a pin hole, a pad holder and a pressing plate, wherein a pine hole is formed in the graphite flake, the graphite flake and the pad holder are fixed into a whole through the pressing plate, and the graphite flake moves together with the pad holder. Through the graphite flake which is integrally fixed to the pad holder and moves together with the pad holder, the thrust bearing is suitable for different lubricating media; meanwhile, through the pin hole formed in the graphite flake, the membrane pressure and temperature a membrane formed by the lubricating media can be directly detected, the actual working condition in the thrust bearing can be mastered, real-time monitoring and timely adjusting can be achieved, the service environment of the thrust bearing is improved according to the actual work condition, and the service life of the thrust bearing is prolonged.

Description

technical field [0001] The invention relates to the technical field of bearing lubrication, in particular to a thrust bearing capable of testing all the loads of each pad. Background technique [0002] The thrust bearing is a mechanical structural component that applies the principle of liquid lubrication and is one of the key components of the generator set. It carries all the axial loads of the generator set. The support method of the thrust bearing plays a vital role in the safe and stable operation of the thrust bearing and the unit. The commonly used rigid screw support structure is not easy to adjust, and the force of the tiles makes the force of each tile more uneven, which often affects the thrust. The safe operation of the bearing may even cause the tile burning accident of the unit, resulting in economic losses of the power station. [0003] In the nuclear power technology system, the main pump of the nuclear reactor is a shielded electric pump, that is, the pump ...

AI Technical Summary

Problems solved by technology

[0006] In view of the above-mentioned problems existing in the prior art, the object of the present invention is to provide a thrust bearing, which can detect the oil film temperature and oil film force inside the bearing, and also includes self-balancing and following functions, and has the function of automatically adjusting the height difference of each tile , that is, the overlapping structure of the balance weight; this overlapping structure can complete the adjustment work of adjusting the height difference of each tile under the condition of a certain preload
