Description

Tilting pad thrust bearing and tiliting pad thrust bearing assembly}

The present invention relates to a tilting pad thrust bearing and a tilting pad thrust bearing assembly, and more specifically, a tilting pad thrust bearing capable of distributing a load concentrated on a part of the thrust bearing due to eccentricity or tilting of a rotating shaft such as a rotor, and It relates to a tilting pad thrust bearing assembly.

In general, a bearing is a device that supports a rotating axis and a reciprocating axis that rotates to maintain smooth motion. These types of bearings are classified into sliding bearings and roller bearings according to the contact method between the shaft and the bearing. In addition, the bearings are classified into radial bearings and thrust bearings according to the direction in which the load acts on the shaft, and thrust bearings can be used to support axial thrust of a rotating shaft rotating at high speed, such as a rotor of a turbine. Can.

In general, a turbine converts thermal energy of combustion gas or steam supplied from a boiler into the rotational force of the turbine rotor, and generates electricity by driving the generator with the rotational force of the rotor. The axial thrust of the turbine rotor is also supported by thrust bearings.

Today, various types of equipment such as turbine rotors are designed such that the rotational speed of a rotating shaft such as a rotor gradually rotates at high speed for high efficiency and light weight.

As such, as the rotating shaft such as the rotor rotates at a high speed, the rotating shaft may be tilted due to vibration of the rotating shaft or the rotating shaft may be tilted due to the weight of the rotating shaft, whereby a concentrated load is applied to a part of the thrust bearing supporting the rotating shaft. .

As described above, when a concentrated load is applied to a part of the thrust bearing by tilting the rotating shaft, the thrust bearing having a conventional pad has a problem in that vibration is further increased due to thermal deformation due to temperature variation in the upper pad and the lower pad.

In addition, in the conventional thrust bearing, a pad or a tilting pad is broken depending on a load concentrated only in part, so that the replacement cost of the thrust bearing increases, and productivity decreases as a device such as a turbine must be stopped to replace the thrust bearing. There was a problem.

Moreover, the conventional tilting pad thrust bearing has a problem in that the structure has a complicated structure, so manufacturing time and manufacturing cost are high, and the thickness of the tilting pad thrust bearing is too thick.
