Description
Technical field
The utility model relates to integral type screw air compressor.
Background technology
The many employings of existing air compressor structure as shown in Figure 1, comprises threephase asynchronous 1, flange 2, shaft coupling 3, helical-lobe compressor main body 102 forms.Threephase asynchronous 1 is connected by shaft coupling 3 with helical-lobe compressor main body 102, has flange 2 in the external stability of shaft coupling 3.This structure has following shortcoming: 1, install parts many, complex structure; 2, take up room greatly, material therefor is many; 3, threephase asynchronous is connected with helical-lobe compressor main body by shaft coupling, and failure rate is high, and transmission efficiency is low.
Utility model content
For there being the defect of technology on overcoming, the purpose of this utility model is intended to propose a kind ofly reduce parts, integral type screw air compressor that transmission efficiency is high.
For achieving the above object, the utility model adopts following technical scheme:
Integral type screw air compressor, is characterized in that: comprise motor, helical-lobe compressor main body; Described motor is connected by adpting flange with helical-lobe compressor main body, adpting flange is provided with fastening screw; Described motor has a cylinder barrel shaped support; Described support is connected by trip bolt with adpting flange; The air inlet of described support is provided with the wind scooper of arc; Described motor internal arranges the motor stator that can produce the rotation of rotating magnetic field rotor driven; Described rotor is fixed on the direction of axis line of motor internal by axially fastening screw axial; The end of described rotor connects flabellum.
Explanation and the further scheme of such scheme are as follows:
In such scheme, the air outlet of described motor is provided with the filter screen for stoping foreign matter to enter motor.
Because technique scheme is used, the utility model compared with prior art has following advantages:
The structure of the integral type screw compression air engine that the utility model provides is that motor is directly connected with helical lobe compressor host, middle without shaft coupling connection, eliminates motor bearings mechanism, decrease parts, taking volume and reduce, is 1/3 of ordinary construction, cost reduces, and structure is simply easy for installation; Motor direct-drive helical-lobe compressor simultaneously, transmission efficiency improves.
Accompanying drawing explanation
Fig. 1 is the structural representation of existing air compressor;
Fig. 2 is structural representation of the present utility model;
Fig. 3 is the structural representation of support in the utility model.
In above accompanying drawing: 1, threephase asynchronous; 2, flange; 3, shaft coupling;
101, motor; 102, helical-lobe compressor main body; 103, adpting flange; 104, screw; 105, support; 106, trip bolt; 107, air inlet; 108, wind scooper; 109, rotor; 110, motor stator; 111, screw is axially fastened; 112, flabellum; 113, air outlet; 114, filter screen.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described:
Embodiment: shown in Fig. 2-Fig. 3:
Integral type screw air compressor, comprises motor 101, helical-lobe compressor main body 102; Described motor 101 is connected by adpting flange 103 with helical-lobe compressor main body 102, adpting flange 103 is provided with fastening screw 104; Described motor 101 has a cylinder barrel shaped support 105; Described support 101 is connected by trip bolt 106 with adpting flange 103; Air inlet 107 place of described support 105 is provided with the wind scooper 108 of arc; Described motor 101 inside arranges the motor stator 110 that can produce rotating magnetic field rotor driven 109 rotation; Described rotor 109 is axially fixed in by axially fastening screw 111 on the direction of axis line of motor 101 inside; The end of described rotor 109 connects flabellum 112; The air outlet 113 of described motor 101 is provided with the filter screen 114 for stoping foreign matter to enter motor 101.
Helical-lobe compressor main body 102 is connected with motor 101, fastening good by adpting flange 103, screw 104.Open motor 101, motor stator 110 produces rotating magnetic field, and rotor driven 109 rotates.In the air inlet 107 of motor 101, the flabellum 112 on rotor 109 absorbs air after rotating from here, by extruding air circulation to front end air outlet 113, takes away the heat that motor stator 110 produces in the process, plays thermolysis.At motor air outlet 113 place, be provided with filter screen 114 and prevent foreign matter from entering motor 101, affect motor 101 and normally work.
The utility model realizes motor and is directly connected with helical-lobe compressor main body, and eliminate the part of shaft coupling, transmission efficiency is high, and failure rate reduces.Meanwhile, eliminate the bearing of motor, decrease parts, reduce cost, simplified structure, easy for installation.
Above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to person skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection range of the present utility model with this.All equivalences done according to the utility model change or modify, and all should be encompassed within protection range of the present utility model.
