In addition, a side of shell 10 is provided with the suction port 11 of the cooled gas that imports the freeze cycle rapid steamer, and the opposite side of shell 10 is provided with the cooled gas that imports to shell 10, by connecting the 1st oil circuit of the 1st pressing chamber A, imports to the 1st pressing chamber A.The gas of the 1st compression by connecting the 2nd oil circuit of the 1st pressing chamber and the 2nd pressing chamber, is sent to the 2nd pressing chamber B among the 1st pressing chamber A, and the side of the 2nd pressing chamber B is provided with the exhaust port that the gas of the 2nd compression among the 2nd pressing chamber B is discharged.
What axle the 1st, 2 supporting attachments 20,30 were provided with that a side of the coverage rate 21,31 of certain thickness and area forms prolongs the bearing housing 22,32 that protrudes to motor M direction, and there is the shaft insertion hole 23,33 that inserts axle the centre that connects bearing housing 22,32.Be inserted in the live axle 50 of the shaft insertion hole 23,33 of axle the 1st, 2 supporting attachments, with the radial bearing R that radial direction is supported, radial bearing R is provided with the thin slice bearing that is suitable for high speed rotating.
As shown in Figure 2, the thin slice bearing is a plurality of mounting grooves 24,34 by length direction that are formed with the certain width and the degree of depth on the inwall of shaft insertion hole 23,33 of axle the 1st, 2 supporting attachments 20,30, fixingly on a plurality of mounting grooves 24,34 inserts effigurate thin slice 110.Thin slice 110 is the curve formation fixed by, is made of the fixing part 112 that is inserted in mounting groove 24,34 after prolongation folds on supporting surface on the live axle 111 and the supporting surface 111.In order to reduce the wearing and tearing of thin slice 110, spraying treatmen is carried out on the surface.
120 is the Sealings that seal between the 2nd pressing chamber B and the M of motor room, the 130th, and diffuser.
The effect of aforesaid turbocompressor is as follows: at first, after connecting power supply, drive motor 40 starts, and the rotating force of drive motor 40 is communicated to 80,90, the 1,2 turbine 80,90 each spinning in the 1st, 2 pressing chamber A, B of the 1st, 2 turbines by live axle 50.
When 1st, 2 turbines 80,90 rotate, the cooled gas of rapid steamer is drawn into the M of motor room of shell 10 by the suction port 11 of shell 10, the cooled gas that is drawn into the M of motor room flows at the M of motor room, behind the drive motor 40 of M inside, cool motors chamber, enter into the 1st pressing chamber A simultaneously by the 1st oil circuit.When the kinergety that enters into the 1st turbine 80 that the cooled gas of the 1st pressing chamber A accepts converts static pressure to, among the 1st compressor A the 1st time the compression after, enter into the 2nd pressing chamber B by the 2nd oil circuit, when the kinergety that enters into the 2nd turbine 90 that the cooled gas of the 2nd pressing chamber B accepts converts static pressure to, after the 2nd compression, discharge among the 2nd compressor B by exhaust port.
The pressure of the 1st pressing chamber A is less than the 2nd pressing chamber B and the M of motor room in the said process, its pressure acts on the axle direction of live axle 50, axial power is held T by thrust axis and is supported, the weight of live axle 50 own and the weight of bonded block, apply power to radial direction, supported by radial bearing R both thin slice bearing.
Below the thin slice bearing is described in detail as follows in the process of supporting live axle 50: at first live axle 50 begin to drive the time, both during driven at low speed, with be rotated under supporting surface 111 state of contact of thin slice 110, when speed was increased to high speed rotating gradually, the gas barrier layer that the gas dynamic pressure that forms between the supporting surface 111 of live axle 50 and thin slice causes was supported live axle 50.
But above-mentioned original structure is to support the frictional heat that takes place between the thin slice bearing of live axle 50 and the live axle 50 when low speed rotation, the heat of peripheries such as the heat generation that produces among hot and the 1st pressing chamber A that the thrust-bearing T of the axle direction support of live axle 50 upward produces is communicated on the thin slice bearing simultaneously, the consistent condition of high temperature that maintains of thin slice bearing, make the coating film damage of the thin slice 110 that constitutes the thin slice bearing, frictional loss when increasing primary starting, reduce the life-span of parts, and the coating film that occurs damaging is pressed into the problem of live axle 50.
Summary of the invention
