Description

For the gear box structure of centrifuge
Technical field
The present invention relates to Centrifuge Techniques field, more particularly to a kind of gear box structure for centrifuge.
Background technology
The gear-box of vertical subdivision is limited by structure, and market can not have been met to big flow, the need of high-power product Ask；And conventional flat subdivision gear-box there is also very big defect：
1., using sealing tooth, sealing effectiveness is poor, it is impossible to be fully solved gearbox leakage for traditional gearbox oil seal；
2. when only needing to tear open compressor section set, then need all to take upper lower box apart, do not dismantling gear-box, compressor section Can not be assembled in the case of set, overhaul oil sealing and sealing gland, significantly increase maintenance cost and maintenance difficulty；
3. conventional flat dissection type gearbox applications are relatively simple, and a kind of gear-box of model can be only applied to a kind of model Compressor assembly, it is difficult to generalization and seriation.
The content of the invention
It is an object of the invention to overcome the deficiencies in the prior art, there is provided a kind of gear for centrifuge of easy access Box structure.
The object of the present invention is achieved like this：
A kind of gear box structure for centrifuge, including the casing, output shaft and compressor of gear-box housing, institute State output shaft and be rotatably supported at casing, the housing is fixedly connected with casing, the casing includes upper box, lower box, The upper box is fixedly connected with lower box, and only lower box is fixedly connected with the casing in the upper box and lower box.
Preferably, the output end of the lower box is fixed with connecting plate, the connecting plate perpendicular to output shaft, the housing It is fixedly connected with connecting plate.The gear-box is applicable to different model size by changing the size and fit system of connecting plate Compressor, be easy to seriation.
Preferably, spacing is left between the upper box and housing, for assembling shell and the seal of casing.Gear-box It is the operating space that sealing system is provided convenience between compressor section set, is easy to the assembling that oil gas is sealed with maintenance.
Preferably, the seal of the output shaft output end uses labyrinth seal and carbon ring seal, the labyrinth seal position In the inner side of carbon ring seal.Change conventional seals form, using labyrinth teeth plus carbon ring seal, efficiently solve gear-box oil leak and ask Topic.
Preferably, when gear box structure is applied to one-stage centrifugal machine, the seal of the non-output end of output shaft is used Labyrinth seal and closure, the labyrinth seal are located at the inner side of closure.Efficiently solve tooth when being applied to one-stage centrifugal machine Roller box Leakage.
Preferably, the output end of the output shaft is provided with the end-tooth for torsion pass.The transmission of axle moment of torsion uses end-tooth Torsion pass, the moment of torsion of end-tooth transmission is big, stable drive, can accurately position, bearing capacity good with centering, structural stability strong Deng.
Preferably, the two ends of the output shaft are supported in casing, two end face difference of journal bearing by journal bearing Oil film wedge face is provided with, two journal bearings is born axial thrust.Allow journal bearing while being used as thrust bearing, Axial thrust is undertaken, gear box structure is more compact.
By adopting the above-described technical solution, present invention can apply to single-stage radial compressor, it can also be used to multistage centrifugal Compressor, especially for big flow, powerful compressor with quite varied.
Brief description of the drawings
Fig. 1 is the structural representation that the present invention is applied to one-stage centrifugal machine；
Fig. 2 is the structural representation that the present invention is applied to two-stage centrifugal machine；
Fig. 3 removes the structural representation of connecting plate part for Fig. 1.
Reference
In accompanying drawing, 1 is lower box, and 2 is end cap, and 3 is upper box, and 4 is carbon ring seal, and 5 is output shaft, and 6 is sealing gland, and 7 are Connecting plate, 8 is housing.
Specific embodiment
It is a kind of embodiment of the gear box structure for centrifuge referring to Fig. 1, Fig. 3, in the present embodiment, gear-box knot Structure is applied to one-stage centrifugal machine, including the casing, output shaft and compressor of gear-box housing, the output shaft is rotationally Casing is supported in, the housing is fixedly connected with casing, the casing includes upper box, lower box, the upper box and nowel Body screw and alignment pin link together.Directly upper box is torn open when can be covered compressor section is not torn open when gear-box is overhauled Open.Only lower box is fixedly connected with the casing in the upper box and lower box, and this design can individually tear upper box open without influence Other parts, while tear open can be in order to avoid tear the casing of gear-box, easy access open when compressor section covers.The output end of the lower box is consolidated Surely have a connecting plate, connecting plate uses mode connects for screw with lower box, the connecting plate perpendicular to output shaft, the housing and connecting plate It is fixedly connected.
Spacing is left between the upper box and housing, for assembling shell and the seal of casing.Compression can not torn open Machine portion directly changes oil sealing, sealing gland when covering, and these have all greatly saved maintenance cost.
The seal of the output shaft output end uses labyrinth seal and carbon ring seal, and it is close that the labyrinth seal is located at carbocyclic ring The inner side of envelope；The seal of the non-output end of output shaft uses labyrinth seal and closure, and the labyrinth seal is located at sealing The inner side of lid.
The two ends of the output shaft are supported in casing by journal bearing, and the end face of two journal bearings is respectively equipped with oil film wedge Face, allows two journal bearings to bear axial thrust；The output end of the output shaft is provided with the end-tooth for torsion pass.
The present invention is not limited solely to above-described embodiment, referring to Fig. 2, be gear box structure of the invention be applied to two grades from Scheming.
Finally illustrate, preferred embodiment above is merely illustrative of the technical solution of the present invention and unrestricted, although logical Cross above preferred embodiment to be described in detail the present invention, it is to be understood by those skilled in the art that can be Various changes are made to it in form and in details, without departing from claims of the present invention limited range.
