Technical field
the utility model relates to a kind of helical-lobe compressor, especially a kind of helical-lobe compressor actuation techniques, specifically a kind of helical lobe compressor host synchromesh gear driving structure without key transmission.
Background technique
at present, general oil free screw compressor and hydrojet technical screw compressor main frame all arrange synchromesh gear at the same shaft extension end of yin, yang rotor, its object is that male rotor passes through synchromesh gear transmitting torque and drives female rotor rotation, ensures to keep certain back lash between negative and positive rotor tooth channel profile simultaneously.Traditional mode of structure is that male rotor synchromesh gear connects with male rotor axle journal by keyway, female rotor axle journal connects (because female rotor pitch circle is larger than male rotor pitch circle with female rotor synchromesh gear wheel hub by keyway, corresponding female rotor synchromesh gear is also larger, therefore gap control adjustment link is set on female rotor mostly), thick thin two plate gears that connect with female rotor wheel hub plate, thick gear transmission moment of torsion, thin gear ensures back lash, thick, thin two plate gears are all fixed by bolt and main synchromesh gear, it is as follows that its function realizes principle: male rotor axle passes to male rotor synchromesh gear by key by moment of torsion, male rotor synchromesh gear passes to the main synchromesh gear of female rotor by gear by moment of torsion, moment of torsion is passed to female rotor synchromesh gear wheel hub by the main synchromesh gear of female rotor, thereby female rotor synchromesh gear wheel hub passes to female rotor by key by moment of torsion and drives female rotor rotation, this process has realized the object of transmitting torque, web gear on female rotor is by staggering a very small angle to fill up synchromesh gear play with the main synchromesh gear of female rotor, thereby ensured can ensure enough safety clearances between negative and positive rotor tooth channel profile.Because key and keyway arrangements exist uneven inertia, in High Rotation Speed situation, directly have influence on main frame vibrations and noise.
Summary of the invention
The purpose of this utility model is can directly have influence on the problem that main frame vibrations are large, noise is high because the existence of uneven inertia causes in High Rotation Speed situation while realizing transmission of power for existing helical-lobe compressor by key and keyway, designs a kind of helical lobe compressor host synchromesh gear driving structure without key transmission.
The technical solution of the utility model is:
A kind of helical lobe compressor host synchromesh gear driving structure, it comprises male rotor 1 and female rotor 2, male rotor and female rotor are arranged on respectively on corresponding male rotor axle 6 and female rotor axle 7, one end live axle of male rotor axle 6 is connected, on the other end of the male rotor axle 6 described in it is characterized in that, interference fit is provided with male rotor synchromesh gear 3, male rotor synchromesh gear 3 engages with female rotor synchromesh gear 4, female rotor synchromesh gear 4 is arranged on female rotor synchromesh gear wheel hub 5, and male rotor synchromesh gear wheel hub 5 is arranged on female rotor axle 7 by interference fit.
Described female rotor synchromesh gear 4 is fixed on female rotor synchromesh gear wheel hub 5 by bolt 8.
The beneficial effects of the utility model:
Synchronous gear structure form of the present utility model is different from conventional construction completely: first between rotor shaft and synchromesh gear (and synchromesh gear wheel hub), cancelled key connecting and adopted interference fit, by frictional force transmitting torque, its advantage is that moment of torsion transmission is large and without uneven inertia (key and keyway arrangements exist uneven inertia, directly have influence on main frame vibrations and noise in High Rotation Speed situation); Male rotor synchromesh gear interference fit connects with male rotor axle, female rotor synchromesh gear wheel hub connects with female rotor interference fit, female rotor synchromesh gear wheel hub and female rotor synchromesh gear are bolted, with frictional force transmitting torque, the axle journal of simultaneous wheels hub as the installation positioning shaft of female rotor synchromesh gear to ensure coaxality, this structure has realized the object of synchromesh gear transmitting torque, and rotor back lash ensures (controlling the sideshake of synchromesh gear) by the accuracy of gear.
Structural type of the present utility model is simple, axial dimension compactness, and simple installation is quick, and reliability is high.
Brief description of the drawings
Fig. 1 is the synchromesh gear driving structure schematic diagram of existing helical-lobe compressor.
Fig. 2 is the synchromesh gear driving structure schematic diagram of helical-lobe compressor of the present utility model.
In figure: 4-1 is the thick synchromesh gear of female rotor of the prior art, 4-2 is the thin synchromesh gear of female rotor of the prior art, and 9 is key.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
As shown in Figure 2.
A kind of helical lobe compressor host synchromesh gear driving structure, it comprises male rotor 1 and female rotor 2, male rotor and female rotor are arranged on respectively on corresponding male rotor axle 6 and female rotor axle 7, one end live axle of male rotor axle 6 is connected, on the other end of described male rotor axle 6, interference fit is provided with male rotor synchromesh gear 3, male rotor synchromesh gear 3 engages with female rotor synchromesh gear 4, female rotor synchromesh gear 4 is arranged on female rotor synchromesh gear wheel hub 5 by bolt 8, and male rotor synchromesh gear wheel hub 5 is arranged on female rotor axle 7 by interference fit.
As shown in Figure 2, male rotor axle connects transmitting torque Zhiyang rotor synchronous gear with male rotor synchromesh gear with interference fit, male rotor synchromesh gear transmits torque to female rotor synchromesh gear, female rotor synchromesh gear is by frictional force (end face is close to generation frictional force) transmitting torque Zhiyin rotor synchronous gear hub, and wheel hub drives female rotor rotation by frictional force (interference fit).Endoporus and the axle journal interference fit of female rotor synchromesh gear hub spindle neck portion, its axle journal cylindrical while or positioning shaft of female rotor synchromesh gear, this structure has shortened the length of shaft of rotor effectively, its key problem in technology point is also to need to consider that the excircle dimension of axle journal can increase after endoporus and rotor shaft interference fit, therefore the initial manufacture size of axle journal cylindrical need to compensate this size increment.Realized moment of torsion transmission by this structure.
Owing to needing to ensure rational back lash between negative and positive rotor, (process profiles of tooth by 5 grades of high class gear requirements by the requirement on machining accuracy that improves synchromesh gear, in theoretical centre distance situation, the sideshake of synchromesh gear is controlled at 0.006～0.03mm), therefore only need a slice synchromesh gear just can ensure the back lash between negative and positive rotor.Its installation steps are as follows, hot jacket assembling male rotor synchromesh gear, female rotor synchromesh gear wheel hub, then female rotor synchromesh gear is installed in cold conditions situation, is set behind the back lash between negative and positive rotor tooth channel profile and with bolt, female rotor synchromesh gear is fixed on female rotor synchromesh gear wheel hub and has completed installation process.With respect to conventional construction, structural type of the present utility model is simple, axial dimension compactness, and simple installation is quick, and reliability is high.
The utility model does not relate to partly all prior aries that maybe can adopt same as the prior art to be realized.
