What is the difference between radial and thrust bearing of a steam turbine?

The thrust bearing of the steam turbine mainly bears the axial thrust of the rotor and determines the axial position of the rotor in the cylinder. The radial bearing generates an oil film when the rotor rotates, mainly bearing the mass of the rotor and the centrifugal force caused by the imbalance of the rotor mass, and determining the radial position of the rotor.But what is the difference between radial and thrust bearing of a steam turbine?

What is the difference between radial and thrust bearing of a steam turbine--A thrust bearing is a special bearing used to specifically support the axial force, which is the bearing of the force in the direction parallel to the shaft.Thrust bearings are also known as thrust bearings--What is the difference between radial and thrust bearing of a steam turbine.

What is the difference between radial and thrust bearing of a steam turbine--The thrust ball bearing is a separate type of bearing, and the shaft ring and the seat ring can be separated from the components of the cage and the steel ball. The shaft ring is a ferrule that cooperates with the shaft. The seat ring is a ferrule that cooperates with the bearing housing hole, and there is a gap between the shaft; the thrust ball bearing can only bear the axial load, and the one-way thrust ball bearing can only bear Axial load in one direction, two-way thrust ball bearings can withstand axial loads in two directions; thrust ball bearings can not limit the radial displacement of the shaft, the limit speed is very low, one-way thrust ball bearings can limit one of the shaft and the housing Axial displacement of the direction, the two-way bearing can limit the axial displacement in both directions--What is the difference between radial and thrust bearing of a steam turbine.

What is the difference between radial and thrust bearing of a steam turbine--Thrust roller bearings are used to support axial and radial combined loads with axial loads, but radial loads must not exceed 55% of axial loads. Compared with other thrust roller bearings, this type of bearing has a low friction factor, high speed and self-aligning performance. The roller of the 29000 type bearing is an asymmetrical spherical roller, which can reduce the relative sliding of the roller and the raceway during operation, and has a long roller, a large diameter, a large number of rollers, a high load capacity, and is usually oil lubricated. Individual low speed conditions can be lubricated with grease. In design selection, it should be preferred; 80000 thrust cylindrical roller bearings, 90000 thrust tapered roller bearings and AXK thrust needle bearings can withstand one-way axial loads, which is more axial than thrust ball bearings. The load capacity is much larger, and the rigidity is large and the axial space is small. Thrust cylindrical roller bearings and thrust needle roller bearings are suitable for low speed applications. Thrust tapered roller bearings have a slightly higher rotational speed than thrust cylindrical roller bearings--What is the difference between radial and thrust bearing of a steam turbine.

What is the difference between radial and thrust bearing of a steam turbine--Radial bearings are bearings that are primarily subjected to radial forces.

What is the difference between radial and thrust bearing of a steam turbine--The part of the shaft that is supported by the bearing is called the journal, and the part that matches the journal is called the bearing bush. The bearing that is made into a full cylindrical shape is called the bushing (Fig. 1). The part of the bearing bush is generally referred to as a shell member, the upper half of which is called a bearing cap and the lower half is called a bearing seat. The cover and the seat are coupled by a stud, and the joint faces of the two are positioned by a stop or a pin, and spacers of different thicknesses can be placed to adjust the bearing clearance. Most bearings have a joint surface that is horizontal and slanted to accommodate the load direction approaching perpendicular to the joint surface. In order to facilitate the entry of lubricating oil between the friction surfaces, the bearing cover is provided with an oil filling hole, and the bearing bush has an axial oil groove for distributing lubricating oil. The bearing cap and seat are mostly made of cast iron, and the load-bearing steel or steel plate welded structure is used--What is the difference between radial and thrust bearing of a steam turbine.
