The biaxial compressor disclosed by the utility model adopts the design of double-shaft-connection integrated compressor; and the connecting shaft is connected with the male rotor extending shaft provided with a conical part through a conical sleeve and a bolt, the defect of large torque in the case of single-shaft connection can be overcome, the service life of the compressor is greatly prolonged, and the subsequent maintenance work of the compressor is facilitated.
Description
Technical field
The utility model relates to a kind of compressor, more precisely a kind of compressor with twin shaft.
Background technique
Permanent magnetism helical-lobe compressor is because of its compact structure, and transmission efficiency advantages of higher, makes its market share more and more higher.Permanent magnetism helical-lobe compressor on existing market adopts the mode of overhanging section of axle of independent elongation male rotor to combine with magneto completely.As shown in Figure 2, it comprises that the design of two section axle mainly comprises male rotor outrigger shaft 1 ', the coupling shaft 2 ' being connected with motor, key 3 ', motor transfer part fixed plate 4 ', connecting bolt 5 ', this kind of mode not only makes overhanging section of bearing of male rotor be subject to very large moment of torsion, greatly reduce the life-span of compressor, also increased the maintenance difficulty of compressor simultaneously.For the easily damaged parts shaft seal of compressor, if the single axis of elongation, the bonding part that needs to take apart motor, could take out shaft seal, and therefore this complex structure is changed also than difficulty.
Model utility content
The purpose of this utility model is to provide a kind of Biaxial Compression machine, and it can solve above-mentioned shortcoming of the prior art.
The utility model is by the following technical solutions:
A kind of Biaxial Compression machine, comprises a male rotor, and its right-hand member is provided with a male rotor outrigger shaft, and the right-hand member of described male rotor outrigger shaft connects the left end of a coupling shaft, and the right-hand member of described coupling shaft connects a motor.
The right-hand member of described male rotor outrigger shaft is provided with a tapered portion, and described tapered portion is sheathed on the inside of described coupling shaft left end.
Described tapered portion and described coupling shaft interference fit.
Also comprise a bolt, it is located at described coupling shaft inside, and described bolt one end and described tapered portion be connected and fixed, and the other end of described bolt is fixed on a motor transfer part fixed plate.
Described motor transfer part fixed plate is fixed described motor.
The outside of described coupling shaft is arranged with key.
The utility model has the advantages that: the two section of the utility model axle connects integrated form compressor design, by coupling shaft is connected with the male rotor outrigger shaft tapered sleeve and the bolt that are provided with tapered portion, the large defect of moment of torsion while not only having improved single axle connection, greatly improve the life-span of compressor, and facilitated the follow-up maintenance operation of compressor.
Brief description of the drawings
Below in conjunction with embodiment and accompanying drawing, the utility model is elaborated, wherein:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of prior art.
Embodiment
Further set forth embodiment of the present utility model below in conjunction with accompanying drawing:
As shown in Figure 1, the utility model discloses a kind of Biaxial Compression machine, comprises male rotor outrigger shaft 1, coupling shaft 2, key 3, motor transfer part fixed plate 4, bolt 5, male rotor 6 and motor 7.
Male rotor right-hand member is provided with a male rotor outrigger shaft, and the right-hand member of described male rotor outrigger shaft connects the left end of a coupling shaft, and the right-hand member of described coupling shaft connects a motor.The right-hand member of described male rotor outrigger shaft is provided with a tapered portion, and described tapered portion is sheathed on the inside of described coupling shaft left end, described tapered portion and described coupling shaft interference fit.
The utility model also comprises a bolt, and it is located at described coupling shaft inside, and described bolt one end and described tapered portion be connected and fixed, and the other end of described bolt is fixed on a motor transfer part fixed plate, and described motor transfer part fixed plate is fixed described motor.
The outside of coupling shaft described in the utility model is arranged with key.
Male rotor outrigger shaft 1 is mainly used in and being connected of coupling shaft 2, and the tapered portion on it is connected with coupling shaft.This kind of design is divided into an axle on the axle of two different diameters of axle.The structural design of tapered portion is according to GB/T1570-2005 standard, press the taper design of 1:10, and adopt the drive fit of two axle interference fit, the male rotor of driven by motor helical-lobe compressor is rotated, driving torque, convert electrical energy into mechanical energy, finally mechanical energy is changed into the pressurized gas that we need.Bolt hole on it is for strengthening the fixing of motor transfer part.
The coupling shaft 2 connected with motor is mainly used in being connected motor transfer part and compressor male rotor, essence is equivalent to coupling, keyway on it is connected with motor, conical bore is connected with male rotor outrigger shaft tapered portion, not only realize the transmission of two axles, and realize the axial restraint of motor transfer part, saved the axial fixing structure in motor left side in permanent magnet motor structure simultaneously.Bolt hole is connected with bolt, for the axial restraint of motor.
Key is mainly used in coupling shaft and motor transfer part, transmits Motor torque, drives coupling shaft to rotate.Motor transfer part fixed plate is mainly used in the axial restraint of motor, and the bolt hole on it is exactly for fixed electrical machinery transfer part.Connecting bolt 5 is mainly used in connecting male rotor outrigger shaft 1, coupling shaft 2, fixed plate 3.
Using method of the present utility model is as follows: first compressor complete machine is installed, then coupling shaft is contained in conical shaft extension, load onto key 3 simultaneously, again the bracket of motor is fixed on compressor flange dish, load onto successively the transfer part of determining of motor, finally load onto motor transfer part fixed plate, and lock bolt 5.
If need overhaul all parts in compressor, only bolt 5 need be removed from coupling shaft 2 and the tapered portion of male rotor outrigger shaft, then motor is removed together with coupling shaft, compressor will become independently one so, now its maintenance will be the same with Normal squeezing machine, therefore keep in repair very convenient.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any amendments of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
