    one
    The invention relates to compressor building, in particular to volumetric compressors or volumetric-type fans.
    The purpose of the invention is to carry out a compact, low weight and inertia of the compressor and to provide a sample of gaps.
    FIG. 1 shows a screw compressor, a plan view; figure 2 - the same. longitudinal section; in FIG. 3, section A-A in FIG. 2
    The screw compressor contains a winding 1 and a leading 2 rotors located in two cylindrical chambers 3 and 4, formed in the housing 5 by a cover 6 and a front partition 7, the follower 8 and the lead. 9 shafts, respectively connected with follower 1 and leading 2 rotors and passing through openings in the partition 7 into the cavity 10 formed by the partition 7 and the clamp 11. At the ends of the shafts 8 and 9 are installed synchronizing gears 12-14.
    The rotors 1 and 2 are made with axial grooves 15 and 16. 8 and 9 are mounted on bearings 17 and 18, forming the inner shoulder 19, and on bearings 20 and 21. Bearings 17, 18, 20 and 21 are located in the axial grooves 15 and 16, respectively, and rests on the sleeves 22 secured to the lid 6 along

    JQ screw means 23. Seals 24 are installed between sleeves 22 and rotors 1 and 2 and are axially held by rings 25.
    The partition 7 is provided with tubular portions 26, coaxial holes in the partition 7 and installed in the rotors. Between the inner surface of the section 26 and the shaft 8 is installed o-ring 27 and the bearing 28.
    Each shaft 8 and 9 contains an enlarged diameter head 29 with periphery pshitsy, which are pressed. The head 29 is held in the body of the rotors 1 and 2 by a locking ring 30 screwed on the thread.
     At the end of the shaft 8 protruding beyond the partition 7, there are two coaxially retracting 1x clearances of gears 12 and 13 to compensate for the angular backlash in the engagement of the rotors 1 and 2. The gears 12 and 13 are in engagement with the wheel 14 located at the end of the shaft 9 connected with the pulley 31 intended for connecting to the drive unit of the compressor drive.
    The gear wheel 14 is provided with a sleeve 32 mounted on the shaft 9, on the outer surface of which the bearing 33 and the annular seal 34 are placed.
    The gears 12-14 are closed with a cap 11, in which a seal 35 is placed,
    The ratio of the diameters of the pitch of the gear wheels 12-14 is the same as the ratio of the spiral cut-outs of the rotors 1 and 2.
    In order to reduce the inertia, the shafts 8 and 9 are made partially hollow with inner space 36 and 37. These shafts are made, for example, by cold forging.
    The input window 38 and the output window 39 are formed in the center of the housing 5, on each side of the latter. Windows 38 and 39 can also be performed on the front of the case.
    The proposed compressor design makes it possible to manufacture rotors 1 and 2 from light alloys, in particular from aluminum alloys, and also from rigid plastic material, for example, from polyamide with glass filler. Since the shafts 8 and 9 consist of two parts, it is possible for the rotors 1 and 2 to be made by casting directly into the matching parts of the shafts 8 and 9, thereby providing a strong bond between these elements.
    In addition, the walls of chambers 3 and 4, as well as the outer surfaces of the sliced rotors I and 2, are painted before assembly by a thickened layer of corrosion-resistant material. Such a device solves the problems of gaps that occur during production during compressor assembly. When assembling elements of rotors 1 and 2, they mutually overlap and are located in chambers with a small effort, the first turns provide, by removing the cutting material in some places, the necessary functional clearance, thereby ensuring a mutual connection between the driving wheels 12-14 without angular play. Anticorrosive material contains particles of dry lubricant, ensuring smooth operation without significant heating of the compressor, operating in a dry form.
    Anticorrosive material Nt to be composed of a resin, a bonding material dissolved in a volatile solvent, and particles of graphite
