Embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is described in further detail:
As shown in Figure 1 to 11, the utility model discloses a kind of double rotor opposite direction rotating compressor, comprise permanent magnetic brushless, the first rotor, the second rotor, the first gear, the second gear, major axis, minor axis and shell, described shell comprises cover plate and housing, and the inwall of described cover plate is provided with the bearing being connected with minor axis;
Described the first rotor is installed on major axis by key, described the second rotor is installed on minor axis by key, in the middle of described the first gear and the second gear, be equipped with gear square hole, described major axis one end is connected with permanent magnetic brushless, the other end is connected with the first gear by the square hole of the first gear, described minor axis one end is connected with the second gear by the square hole of the second gear, and the other end is connected with described bearing, described the first gear and the mutual interlock of the second gear;
Described the first rotor periphery is provided with at least one compression end, described the second rotor periphery be correspondingly provided with for the mutual interlock of the compression end with the first rotor and then and the bottom surface of described cover plate, described housing form the compression end of compression chamber or expansion chamber, the bottom surface of described housing is correspondingly provided with suction port, exhaust port, sucking pipe and outlet pipe, described sucking pipe, outlet pipe are connected with described suction port, exhaust port respectively, in described sucking pipe, be provided with the first pressure valve, in described outlet pipe, be provided with the second pressure valve.
Above-mentioned the first rotor and the second rotor have identical geometrical shape, and it is corresponding one by one that two rotor opposite direction rotatings need meet every pair of mutual interlock of compression end.
When the compression end of described the first rotor and bitrochanteric compression end interlock, form a compression chamber and expansion chamber with cover plate, housing, two chamber total volumes are certain, by two rotor compression ends, separate, and with compression end 15, rotate, and two chamber sizes mutually change and mutually transform; The lower end of described housing is provided with suction port, exhaust port, sucking pipe, outlet pipe, the first pressure valve and the second pressure valve, described sucking pipe is connected with the suction port that is positioned at new expansion chamber and increases initial position by the first pressure valve, described outlet pipe by the second pressure valve be positioned at the exhaust port that compression chamber reduces to locate ultimate position and be connected.
Described major axis is comprised of four end faces, gear is fixed on the first major axis end face, the second major axis end face contacts with the inner hole surface that is installed on the bearing on housing bearing groove, the 3rd major axis end face contacts with the rotor bore face of bearing outer ring and the first rotor, play the fixedly effect of major axis and the first rotor, the 4th major axis end face stretches out the brearing bore on cover plate bearing groove, stretch out end face as the central shaft of motor, described housing bearing groove is positioned at each circle central position of housing, and uses corresponding flute profile according to used bearing type.
