Abstract
The utility model relates to a thrust bearing of a horizontal hydraulic generator, comprising a bearing support, a small oil delivery wheel, a small oil collection box, a radial bearing pad, a thrust pad, an oil collection box, an oil gasket, an oil delivery wheel and a thrust disc, wherein, the swinging oil gear and the thrust disc are connected by bolts and through convex-ring spigots and concave-ring spigots; the swinging oil gear is provided with convex-ring spigots, split clearances and oil delivery vanes; the thrust disc is provided with concave-ring spigots. The utility model has a novel structure which is convenient for assembly and disassembly, thereby the optimization of the other parts of the horizontal hydraulic generator is facilitated; meanwhile, the oil circulation mode of a closed oil pump is adopted in the utility model, thereby the cooling effect of the bearing is improved.
Description
Technical field
The utility model belongs to a kind of thrust-bearing of horizontal hydrogenerator.
Background technique
In the existing horizontal hydrogenerator radial-thrust bearing structure, bascthrust dish double as band oil tanker uses, and there are following problems in this structural type.
1, thrust dribbling oil ability.Thrust disc is the critical piece that bears axial force, and the artificer pays attention to this function, and the function of band oil just has been placed on less important relatively position.Generally speaking, just digging several grooves on the cylindrical of thrust disc realizes being with oily ability relatively poor with the function of oil.
2, set structure complexity, the manufacture cost height.Go for oil being taken in the bearing shell, the part of thrust disc must be under pasta, and this also makes has part thrust bearing shoe bubble in deep fat, and the cooling effect of thrust bearing shoe is just relatively poor.If for thrust bearing shoe is higher than pasta, and the part of thrust disc is under pasta, and thrust disc just must be sufficiently large.Thrust disc is special with material, and preparation process is special, and its size has strengthened, and cost of production increases naturally.Secondly, the thrust disc size is big, if consider the lifting of generator amature axle center again, the bearing support axial passage is also enough wide, and causing radially, the bearing structure complexity of bearing shell increases.For the generator set that adopts axial flow fan, fan is contained on the main shaft, and fan base also will design quite greatly, could pass through thrust disc; Fan distinguish, structure are more complicated.
Summary of the invention
The utility model purpose mainly is that traditional horizontal radial thrust bearing is optimized.Measure is separately to make by thrust disc and band oil tanker, finishes the function of oneself separately, and then fits together.
The technical solution of the utility model is: a kind of thrust-bearing of horizontal hydrogenerator, mainly by bearing support, little band oil tanker, little oil box, radially bearing shell, thrust bearing shoe valve, oil box, end lubricating pad, band oil tanker and thrust disc and form, band oil tanker and thrust disc, connect by bolt, the band oil tanker is connected by bulge loop shape seam and hollow toroid seam with thrust disc; The band oil tanker has bulge loop shape seam, and oily blade is with in the distinguish slit; Thrust disc has the hollow toroid seam.
The size of thrust disc determines by the needs of thrust and thrust bearing shoe valve that mainly thrust bearing shoe valve and thrust disc can be higher than pasta.Hollow toroid seam of thrust disc design and band oil tanker bulge loop shape seam location, both pass through Bolt Connection.
The band oil tanker is finished oiling of task, and it can use the aluminum alloy manufacturing of lightweight, is contained in the outside of thrust disc.The structural type that the band oil tanker is adopted distinguish is so that mounting or dismounting.Band oil tanker outside is to be with oily impeller, and the bottom is connected with thrust disc.
The utility model has the advantages that: novel structure, easy accessibility is for other component optimization of unit provides convenience; Adopt airtight class oil pump oil endless form, improve the cooling effect of bearing.
The method of operation and principle
The main composition of bearing and principle are as shown in Figure 1.
The sealing and circulating mode that the bearing oil circuit adopts, in oily circuit process, cold and hot oil was separating before supercooler fully, and the exchange of cold and hot oil has mandatory.
After main shaft rotated the rotating speed reach certain, band oil tanker 3 was transported to thrust bearing shoe 2 tops again with its top on the oil box 5 bottom cold oil bands, drenches on the thrust bearing shoe 2.Cold oil becomes deep fat after having absorbed the heat of thrust bearing shoe 2, flows out from the bottom of bearing shell again.Under the pull of vacuum that produces in the rotation of band oil tanker, stream of hot oil is through the bottom of oil stream cooler 6 arrival oil boxes 5, and so forth.

Embodiment
Shown in Fig. 1-7, the utility model mainly by bearing support 1, little band oil tanker, little oil box, radially bearing shell 2, thrust bearing shoe valve, oil box, end lubricating pad, band oil tanker 3 and thrust disc 4 and form, band oil tanker 3 and thrust disc 4, connect by bolt 11, band oil tanker 3 is connected by bulge loop shape seam 7 and hollow toroid seam 10 with thrust disc 4; Band oil tanker 3 has bulge loop shape seam 7, and oily blade 9 is with in distinguish slit 8; Thrust disc 4 has hollow toroid seam 10.
Shown in Fig. 2,3, band oil tanker 3 has bulge loop shape seam 7, and oily blade 9 is with in distinguish slit 8.Band oil tanker 3 and thrust disc 4 connect by bolt 11, annular stopper 7,10 can allow band oil tanker 3 and thrust disc 4 both locate mutually, also make the band oil tanker 3 of distinguish can bear bigger centrifugal force.
Shown in Fig. 4,5, thrust disc 4 has hollow toroid seam 10.
