Abstract
High-performance compressor precision screw rod designed by the utility model, including bearing neck, rotor section and linkage section, it is characterized in that the rotor section is equipped with helical tooth, bottom of the tooth face between each tooth of helical tooth is equipped with symmetrical groove on the flank in bottom of the tooth face, and groove prolongs the direction of working medium movement and is gradually reduced to completely disappearing, the characteristics of this structure is to increase groove in the bottom of helical tooth, so that between cog area increases, to improve capacity, simultaneously, since the direction that groove prolongs working medium movement is gradually reduced, also compression ratio can be improved, so that helical-lobe compressor obtains better performance.
Description
Technical field
The utility model belongs to a kind of screw rod of machinery field, especially a kind of accurate spiral shell applied to high-performance compressor
Bar.
Background technique
Helical-lobe compressor belongs to rotary type displacement equipment, since its structure is simple, few easy workout part, can in big pressure difference or
Under the operating condition of pressure ratio, delivery temperature is low, insensitive to a large amount of lubricating oil is contained in refrigerant, has good displacement to adjust
Property, it can keep being operated under efficient state under bigger pressure and range of flow, therefore will be used wider and wider
It is general.In helical-lobe compressor, it is crucial that a pair of intermeshing rotor, the flank of tooth and the rotor axis vertical plane of rotor must be cut
Intersection is known as molded lines of rotor.The molded line of rotor is directly related to the compression performance of compressor.
Utility model content
To solve the above problems, the utility model provide it is a kind of there is high compression ratio, and capacity is big, high-performance pressure
Contracting machine precision screw rod.
In order to achieve the above object, high-performance compressor precision screw rod designed by the utility model, including bearing neck, turn
Subsegment and linkage section, it is characterized in that the rotor section is equipped with helical tooth, the bottom of the tooth between each tooth of helical tooth
Face or flank close to bottom of the tooth face are equipped with symmetrical groove, and groove prolongs the direction of working medium movement and is gradually reduced to disappearing completely
It loses.The characteristics of this structure is to increase groove in the bottom of helical tooth, so that between cog area increases, to improve capacity.Together
When, since the direction that groove prolongs working medium movement is gradually reduced, compression ratio can be also improved, so that helical-lobe compressor obtains more preferably
Performance.
Further embodiment is that the rotor section is pyramidal structure, and taper is to prolong the direction that working medium is run gradually to contract
It is small, and screw shell is externally provided in pyramidal structure；It is helical tooth on the outside of the screw sleeve, inside is cooperated with pyramidal structure
Bellmouth, and rotor section and screw shell are sequentially connected by uniformly distributed key.Rotor section and screw shell are separated, can be reduced
The difficulty of processing to improve the processing yields of bottom of the tooth groove, while realizing the replacement of screw shell, thus convenient entire pressure
The maintenance of contracting machine.On the other hand, the fit structure of taper, with working medium traffic direction on the contrary, side when being compressed by working medium acts on
Power guarantees the relative position of rotor section and screw shell, keeps good operation stability.
Compared with prior art, the obtained high-performance compressor precision screw rod of the utility model, under identical size
Reach bigger capacity, while being also able to achieve bigger compression ratio using the groove structure of gradual change.It is additionally contemplates that simultaneously
The convenience of processing machine maintenance, further devises separable rotor structure, has compression efficiency height, stable, maintenance
Convenient feature.
Detailed description of the invention
Fig. 1 is 1 principal shape perspective view of embodiment.
Fig. 2 is 1 rotor section molded lines of embodiment.
Fig. 3 is 2 rotor section molded lines of embodiment.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe.
Embodiment 1.
As shown in Figs. 1-2, the present embodiment description high-performance compressor precision screw rod, including bearing neck 6, rotor section 1 with
And linkage section, the rotor section 1 are equipped with helical tooth 2, are equipped with one on the bottom of the tooth face between each tooth of helical tooth 2
Symmetrical groove 3, and groove 3 prolongs the direction of working medium movement and is gradually reduced to completely disappearing.
Embodiment 2
Shown in Fig. 2, the high-performance compressor precision screw rod of the present embodiment description includes bearing neck, rotor section 1 and connection
Section, the rotor section 1 are equipped with helical tooth 2, the flank or so in the close bottom of the tooth face between each tooth of helical tooth 2
Symmetrically it is equipped with groove 3, and groove 3 prolongs the direction of working medium movement and is gradually reduced to completely disappearing.The rotor section 1 is taper
Structure, taper are to prolong the direction that working medium is run to be gradually reduced, and be externally provided with screw shell 4 in pyramidal structure；The screw rod
Outside of sleeve is helical tooth 2, and inside is the bellmouth with pyramidal structure cooperation, and rotor section 1 and screw shell 4 pass through it is uniformly distributed
Key 5 is sequentially connected.
