Description
Technical field
The utility model relates to a kind of screw air compressor.
Background technique
Helical-lobe compressor is the positive displacement gas compression machinery that a kind of swept volume does rotation motion.The compression of gas relies on the change of volume to realize, and the change of volume reaches do rotation motion in casing by a pair rotor of compressor.The live axle of screw host is driven by the rotor of motor and rotates, the Placement of live axle and rotor generally has straight connection type and belt type, wherein coaxial screw air compressor not only running efficiency is good, and noise is low, reliability is high, obtain certain development in China's compressor industry especially in the recent period.It is very strict that magnetic gap between rotor and stator controls, its size directly has influence on the delivery efficiency of motor, because rotor is directly installed on the input shaft of screw host, when main frame or motor need repairing because of fault, rotor is all directly stressed dials in its end face pull-up in dismounting in the past, so there are the following problems: be interference fit between rotor and main frame input shaft, need larger to draw the power of dialling; Rotor end face is provided with multiple fin, and lifting surface area is little; Rotor is combined layer by layer by silicon steel sheet, and integrity is poor.For above-mentioned reasons, in the process of dismounting rotor, easily cause and deform, not only can have influence on the delivery efficiency of motor, also may sweep the fault of boring.
Summary of the invention
Comparatively bother and the deficiency easily damaging rotor to overcome the dismounting of prior art rotor, the utility model provides during a kind of dismounting can guarantee the indeformable coaxial screw air compressor of rotor.
The technical scheme in the invention for solving the technical problem is:
A kind of coaxial screw air compressor, comprise cabinet, be arranged on the screw host in cabinet and drive motor, it is characterized in that: the live axle of described screw host stretches in the housing of drive motor, and the rotor of described drive motor is socketed on described live axle, live axle is by being connected rotor with the land of rotor coaxial, arrange one between described live axle and rotor and draw pulling axis cover, described draw pulling axis to put setting to draw allocating slot, be set between live axle and land drawing the pulling axis that draws of allocating slot front end, be set between live axle and rotor drawing the pulling axis that draws of allocating slot rear end, the described endoporus drawing pulling axis to overlap and live axle interference fit, the outer ring of drawing pulling axis to overlap and rotor also interference fit.
As preferably, rotor tip penetrates a bolt and is fixedly connected with described live axle.
As preferably, be positioned at and draw the outer surface drawing pulling axis to overlap of allocating slot rear end to be distributed with some salient points.
The live axle of screw host directly connects the rotor of drive motor, live axle is connected by land with rotor, and between connect and one draw pulling axis cover, pulling axis is drawn to overlap and live axle, the equal interference fit of rotor, the front end of drawing pulling axis to overlap is arranged between live axle and land, during dismounting, utilize draw pulling axis to put to offer draw the stressed dismounting of allocating slot, live axle is departed from rotor, guarantees that rotor does not deform.Live axle and the connection of rotor are fixedly connected with by the bolt of end, and draw pulling axis overlap with the surface of contact of rotor on salient point is set, make to draw pulling axis to overlap and rotor close contact, guarantee to have set up draw pulling axis to overlap after do not affect rotor and live axle synchronous axial system.
The beneficial effects of the utility model are: between rotor and screw host input shaft, arrange one draw pulling axis cover, can dismounting rotor process in, utilize it is offered draw the stressed dismounting of allocating slot, guarantee that rotor does not deform.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation drawing pulling axis to overlap.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, a kind of coaxial screw air compressor, comprise chassis 6, chassis 6 is arranged cabinet 5, be arranged on the screw host 4 in cabinet and drive motor 1, in drive motor 1, rotor 2 rotates between stator 3, the live axle of described screw host 4 stretches in the housing of drive motor 1, and the rotor 2 of drive motor is socketed on described live axle 9, live axle 9 is provided with the land 7 with rotor coaxial, live axle 9 is connected by land 7 with rotor 2, arranging one between described live axle and rotor draws pulling axis to overlap 8, allocating slot 10 is drawn in described setting on pulling axis cover 8 of drawing, be arranged between live axle 9 and land 7 drawing the pulling axis cover 8 that draws of allocating slot front end, be set between live axle and rotor drawing the pulling axis that draws of allocating slot rear end, the described endoporus drawing pulling axis to overlap and live axle interference fit, the outer ring of drawing pulling axis to overlap and rotor 2 also interference fit.Rotor afterbody penetrates a bolt and is fixedly connected with described live axle.Be positioned at and draw the outer surface drawing pulling axis to overlap of allocating slot rear end to be distributed with some salient points 11.
The live axle 9 of screw host directly connects the rotor 2 of drive motor, and between connect one draw pulling axis overlap 8, pulling axis is drawn to overlap 8 and live axle 9, rotor 2 all interference fit, the front end of drawing pulling axis to overlap is arranged between live axle and land, during dismounting, utilize draw pulling axis to put to offer draw the stressed dismounting of allocating slot 10, live axle is departed from rotor, guarantees that rotor does not deform.Live axle and the connection of rotor are fixedly connected with by the bolt of afterbody, and draw pulling axis overlap with the surface of contact of rotor on salient point 11 is set, make to draw pulling axis to overlap and rotor close contact, guarantee to have set up draw pulling axis to overlap after do not affect rotor and live axle synchronous axial system.
Between rotor and screw host input shaft, arrange one draw pulling axis cover, can dismounting rotor process in, utilize it is offered draw the stressed dismounting of allocating slot, guarantee that rotor does not deform.
