Below with reference to Fig. 1, the centrifugal compressor 100 according to the utility model embodiment is described.
As shown in Figure 1, thrust disc assembly and bearing 3 can be comprised according to the centrifugal compressor 100 of the utility model embodiment.
Thrust disc assembly can comprise thrust disc 2 and rotating shaft 1, thrust disc 2 and rotating shaft 1 one-body molded.As shown in Figure 1, thrust disc 2 to be located in rotating shaft 1 and coaxially can to arrange with rotating shaft 1, and thrust disc 2 is located on the outer side surface of rotating shaft 1, may be used for the axial force balancing rotating shaft 1.Thus, the assembly process of thrust disc 2 and rotating shaft 1 can be reduced, improve efficiency of assembling, simultaneously because thrust disc 2 and rotating shaft 1 are integrated part, thus the assembly precision of thrust disc 2 and rotating shaft 1 can be improved, avoid bad thrust disc 2 uneven wear caused of assembling due to thrust disc 2 and rotating shaft 1, extend the working life of thrust disc 2, and then reduce the maintenance of centrifugal compressor 100, improve the reliability of centrifugal compressor 100.
As shown in Figure 1, bearing 3 is located in rotating shaft 1 and bearing 3 coordinates with rotating shaft 1, thus the installation that can realize bearing 3 and rotating shaft 1 is fixed.Bearing 3 has radial bearing position 31 and thrust face 32, and radial bearing position 31 is the inner side surface of bearing 3 and is set in rotating shaft 1, can bear the radial force of rotating shaft 1.Thrust face 32 is against on rotating shaft 1 or thrust disc 2 directly or indirectly, for limiting the displacement of rotating shaft 1 and thrust disc 2 along the axis of rotating shaft 1.In an example of the present utility model, as shown in Figure 1, the thrust face 32 of bearing 3 is directly against in rotating shaft 1, directly can limit rotating shaft 1 displacement in the axial direction, limits the axial displacement of thrust disc 2 simultaneously.(scheme not shown) in another example of the present utility model, the thrust face 32 of bearing 3 can be against on thrust disc 2, limit thrust dish 2, along the axial displacement of rotating shaft 1, because rotating shaft 1 and thrust disc 2 are integrally formed, thus can limit rotating shaft 1 displacement in the axial direction.
According to the centrifugal compressor 100 of the utility model embodiment, the radial force of rotating shaft 1 can be balanced on the one hand by bearing 3, restriction rotating shaft 1 displacement vertically.On the other hand because rotating shaft 1 and thrust disc 2 are integrated part, the assembly process of thrust disc 2 and rotating shaft 1 can be reduced, improve efficiency of assembling, avoid bad thrust disc 2 uneven wear caused of assembling due to thrust disc 2 and rotating shaft 1 simultaneously, extend the working life of thrust disc assembly, and then reduce the maintenance of centrifugal compressor 100, improve the reliability of centrifugal compressor 100.
In embodiments more of the present utility model, bearing 3 can comprise radial bearing and thrust-bearing, and the inner peripheral surface of radial bearing forms radial bearing position 31, and at least one side end face of thrust-bearing forms thrust face 32.Such as, in examples more of the present utility model, as shown in Figure 1, a side end face of thrust-bearing is formed as thrust face 32 and is against on thrust disc assembly, and namely thrust-bearing one side is stressed.In other examples of the present utility model, the both sides end face of thrust-bearing is all formed as thrust face 32 and is against on thrust disc assembly, and namely thrust-bearing is two-sided stressed.Like this, be set on the outer circumferential face of rotating shaft 1 by the radial bearing position 31 of radial bearing, the radial force of rotating shaft 1 can be born.The thrust face 32 of thrust-bearing is against on rotating shaft 1 or thrust disc 2, can limit the displacement along the axis of rotating shaft 1 of rotating shaft 1 and thrust disc 2.
In another embodiment of the present utility model, bearing 3 can be combined journal and thrust bearing, ringwise, the inner peripheral surface of combined journal and thrust bearing can form radial bearing position 31 to combined journal and thrust bearing, and at least one side end face of combined journal and thrust bearing can form thrust face 32.Like this, combined journal and thrust bearing is set in rotating shaft 1, and the thrust face 32 of combined journal and thrust bearing is against on rotating shaft 1 or thrust disc 2, thus, not only can be born the radial force of rotating shaft 1 by combined journal and thrust bearing, and rotating shaft 1 or thrust disc 2 displacement in the axial direction can be limited.
Alternatively, combined journal and thrust bearing can be and is arranged in the multiple of thrust disc 2 both sides, namely combined journal and thrust bearing is multiple, and multiple combined journal and thrust bearing 3 is evenly arranged in the both sides of thrust disc 2, thus make rotating shaft 1 at thrust disc 2 both sides stress equalization, avoid because thrust disc 2 both sides unbalance stress causes thrust disc 2 to wear and tear, the assembly precision of thrust disc assembly can be improved simultaneously, extend the working life of thrust disc assembly.
In concrete examples more of the present utility model, rotating shaft 1 can be stepped, and as shown in Figure 1, rotating shaft 1 can be divided into multiple shaft part according to the difference of radial dimension.The radial bearing position 31 of combined journal and thrust bearing is set on the shaft part that in stair-stepping rotating shaft 1, size is little, and the thrust face 32 of combined journal and thrust bearing is against on the shaft shoulder of stair-stepping rotating shaft 1.In example as shown in Figure 1, rotating shaft 1 can comprise the first shaft part 11 and the second shaft part 12 according to the difference of radial dimension, wherein, the radial dimension of the first shaft part 11 is greater than the radial dimension of the second shaft part 12, as shown in Figure 1, combined journal and thrust bearing is set on the second shaft part 12, and the thrust face 32 of combined journal and thrust bearing is against on the shaft shoulder of the first shaft part 11.
Further, thrust disc 2 can be located at the middle part of rotating shaft 1, and portion size rotating shaft 1 with close thrust disc 2 is large and away from little stepped of the size of thrust disc 2.In example as shown in Figure 1, first shaft part 11 is the central axis segment of rotating shaft 1, thrust disc 2 is located on the first shaft part 11, the size of other shaft parts of rotating shaft 1 reduces gradually and is formed stepped on the direction away from the first shaft part 11, thus, when multiple bearing 3 is arranged on the both sides of thrust disc 2, can to be set on the relatively little shaft part of size and to be against on the shaft shoulder of the relatively large shaft part of size, because thrust disc 2 is located at the middle part of rotating shaft 1, thus thrust disc 2 stress balance can be made, and then ensure the normal operation of rotating shaft 1.
Alternatively, combined journal and thrust bearing can be included in two of the bilateral symmetry layout of thrust disc 2, in example as shown in Figure 1, two combined journal and thrust bearings to be set on the second shaft part 12 and to be against on the shaft shoulder of the first shaft part 11, thus can limit the axial displacement of rotating shaft 1.
In examples more of the present utility model, combined journal and thrust bearing is formed with oil supply hole 4, oil supply hole 4 can be used for passing into lubricant oil and by lubricant oil directed radial bearing position 31 and thrust face 32, thus, lubricant oil can be passed into lubricate radial bearing position 31 and thrust face 32, reduce the contact wear of bearing 3 in radial bearing position 31 and thrust face 32 and rotating shaft 1, prevent bearing 3 corrosion and ageing.
In concrete examples more of the present utility model, a side end face of combined journal and thrust bearing forms thrust face 32, and oil supply hole 4 is formed on the opposite side end face of combined journal and thrust bearing.As shown in Figure 1, oil supply hole 4 is formed on the left surface of combined journal and thrust bearing, and can be communicated with radial bearing position 31 with the thrust face 32 of combined journal and thrust bearing 3, thus, facilitate lubricant oil by the thrust face 32 of oil supply hole 4 directed radial thrust composite bearing and radial bearing position 31.
