Turbine people must understand the bearing of learning!

Steam turbine radial bearing is divided into fixed bearing two types of bearings and tilting watts. 1, fixed bearing oil cylinder bearing, elliptical bearings fixed watts watts bearing, more oil is woven and leaf oil bearing ( Currently not used) 。 Ordinary cylindrical bearings, is composed of upper and lower half. The second half of the bearing in vitro has three radial adjusting pad, the upper bearing at the top of the set, a radial adjusting pad for bearing adjustment. For bearing adjustment. Oval tile bearing is self-aligning bearing, has the advantages of less structure on the level in direct casting babbitt bearing the body appearance, will be tile surface processed into elliptical bearing. 2, tilting bearings, bearing four tilting watts in the upper two segment's back, along the steering oil place with spring, make the segment in the back pressure to the tendency of the rotor, avoid the inlet side of the segment and shaft neck brake of undesirable tendency, at the same time in the tile surface feed side inclined, and smooth oil into the tile surface. Half of round, the second half of the tilting composed of two pieces of tilting tile tile bearing, the structure of bearing stability is better than cylindrical bearings, bearing capacity than the general big tilting tile bearing, and tilting tile of partial load bearing and wrong ZhongMin rational teaching the advantages of small. Is a new type of tile surface oil inlet side into the tank with tilting tile bearing, smooth oil with the method of direct oil supply and oil discharge. Each segment has a into the tank, after working in the tile surface smooth oil directly discharge, has less power consumption. The classification of the thrust bearing 1, combined with radial thrust bearing the structure features was put in a body, the radial and thrust bearings bearing is spherical to match corresponding spherical and bearing sleeve body, make the bearings and automatically adjust the deflection of the shaft deformation demand, arrived on the tile surface and the rotor thrust plate has good contact between appearance, the structure is suitable for the flexible rotor and axial load is not too much of a unit. Another for elastic balance type of tile radial thrust bearing, thrust segment is placed on the elastic ring, hosted by elastic ring to produce elastic deformation, in order to reach each piece of tile surface and thrust plate plane have a good contact with the request. This kind of structure used in rigid rotor and the axial load is not too much of a unit. 2, mirra ginsburg tile symmetric bearing, thrust bearing can be used for positive and negative two to work.
