Abstract
The utility model provides a screw compressor, comprising a housing, a male rotor, a female rotor, a motor and a separator. The screw compressor is characterized in that a long bond is arranged on the surface of a rotor shaft of the motor, and the rotor shaft of the motor is fixed together with the rotor shaft of a male rotor by virtue of the long bond, so that the rotor shaft of the male rotor and the rotor shaft of the motor are formed into a whole, the operation reliability of the screw compressor is ensured, and noise generated when the screw compressor runs is effectively reduced.
Description
Technical field
The utility model relates to a kind of compressor, relates in particular to a kind of helical-lobe compressor.
Background technique
Compressor is absolutely necessary in refrigeration system.The compressor that is widely used at present mainly contains piston type, screw type, centrifugal etc.
Screw type refrigerating compressor all adopts initiatively screw rotor rotation of motor driving, and drives driven rotor by the active screw rotor, and screw rotor is divided into the yin, yang rotor and intermeshes, and the rotor outer ring cooperates with housing.When the working rotor of engagement to when rotation, the volume between rotor teeth groove and the housing changes, thereby realizes suction, compression and the eliminating of gas, finishes continuous gas compression circulation.
Join shown in Figure 1ly, Fig. 1 is the sectional view of a kind of helical-lobe compressor of the prior art.Helical-lobe compressor 100 of the prior art, it mainly comprises: housing 10, male rotor 20, female rotor 30, motor 40 and separator 50 also comprise an external lubrication oil supply system (not shown) simultaneously.
Therefore, in the prior art, exist the helical-lobe compressor fluctuation of service, the technological deficiency such as noise is larger.
In view of this, be necessary helical-lobe compressor of the prior art is improved, to address the above problem.
The model utility content
The purpose of this utility model is to provide a kind of helical-lobe compressor, and it can improve the helical-lobe compressor reliability of operation effectively, the noise that produces when reducing the helical-lobe compressor operation.
For realizing above-mentioned model utility purpose, a kind of helical-lobe compressor of the present utility model comprises: housing, male rotor, female rotor, motor and separator, the surface of the rotor shaft of described motor are provided with a long key.
As further improvement of the utility model, the rotor shaft of described long key and described motor has same medial axis.
As further improvement of the utility model, the rotor shaft of described male rotor and the rotor shaft of motor are an overall structure.
As further improvement of the utility model, the rotor shaft of described male rotor is by the mutual fixing of rotor shaft of described long key and described motor.
As further improvement of the utility model, described helical-lobe compressor is the oil-less pump Spiral Lobe Refrigeration Compressor.
Compared with prior art, the beneficial effects of the utility model are: fix by the rotor shaft of long top-notch player's motor and the rotor shaft of male rotor, making the rotor shaft of male rotor and the rotor shaft of motor is an integral body, thereby guaranteed this helical-lobe compressor reliability of operation, the noise that produces when effectively reducing this helical-lobe compressor operation.
Description of drawings
Fig. 1 is the sectional view of a kind of helical-lobe compressor of the prior art;
Fig. 2 is the sectional view in a kind of screw compressor one embodiment of the utility model.
Embodiment
Below in conjunction with each mode of execution shown in the drawings the utility model is elaborated; but should be noted that; these mode of executions are not limitation of the utility model; those of ordinary skills all belong within the protection domain of the present utility model according to these mode of execution institute work energy, method or structural equivalent transformation or alternative.
Shown in please refer to the drawing 2, Fig. 2 is the sectional view in a kind of screw compressor one embodiment of the utility model.In the present embodiment, a kind of helical-lobe compressor 100 comprises: housing 10, male rotor 20, female rotor 30, motor 40 and separator 50, the surface of the rotor shaft 401 of described motor 40 are provided with a long key 402.This motor 40 is AC motor.
In the present embodiment, this long key 402 has same medial axis with the rotor shaft 401 of motor 40.Thereby making the rotor shaft 201 of male rotor 20 and the rotor shaft 401 of motor 40 is an overall structure.The rotor shaft 201 of this male rotor 20 is by the rotor shaft 401 mutual fixings of this long key 402 with described motor 40.
In the present embodiment, this helical-lobe compressor 100 is the oil-less pump Spiral Lobe Refrigeration Compressor.
Above listed a series of detailed description only is specifying for feasibility mode of execution of the present utility model; they are not to limit protection domain of the present utility model, allly do not break away from equivalent mode of execution or the change that the utility model skill spirit does and all should be included within the protection domain of the present utility model.
To those skilled in the art, obviously the utility model is not limited to the details of above-mentioned example embodiment, and in the situation that do not deviate from spirit of the present utility model or essential characteristic, can realize the utility model with other concrete form.Therefore, no matter from which point, all should regard embodiment as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims rather than above-mentioned explanation, therefore is intended to include in the utility model dropping on the implication that is equal to important document of claim and all changes in the scope.Any reference character in the claim should be considered as limit related claim.
In addition, be to be understood that, although this specification is described according to mode of execution, but be not that each mode of execution only comprises an independently technological scheme, this narrating mode of specification only is for clarity sake, those skilled in the art should make specification as a whole, and the technological scheme among each embodiment also can through appropriate combination, form other mode of executions that it will be appreciated by those skilled in the art that.
