Technical field
This utility model relates to a kind of single-screw expander, a kind of energy-efficient single-screw expander.
Background technology
On front side of the tooth of the star-wheel of existing single-screw expander bus to the distance of the addendum flank of star-wheel equal to the tooth of star-wheel
Rear side bus is to the distance of the addendum flank of star-wheel, phase before inflation, and on front side of star-wheel tooth, bus length in screw channel is more than star-wheel
Bus length in screw channel on rear side of tooth, so that the gas moment on this star-wheel two flank is negative value, upon inflation phase, star
On front side of the gear teeth, bus length in screw channel is less than bus length in screw channel on rear side of star-wheel tooth so that on this star-wheel two flank
Gas moment be on the occasion of, but due to expand early stage star-wheel two flanks gas force moment ratio expand later stage star-wheel two flank gas
Moment of volume is much greater so that the gas resultant moment of the gear teeth of the multiple star-wheels engaged with the screw channel of screw rod becomes decompressor motion
The moment of resistance, therefore increase the mechanical loss of screw rod, affect the efficiency of decompressor, also can aggravate the mill of the gear teeth of star-wheel simultaneously
Damage.
Utility model content
In order to solve the problems referred to above, the purpose of this utility model is to provide a kind of work efficiency high, single spiral shell of life-span length
Bar decompressor.
This utility model the technical scheme is that for solving its technical problem
A kind of single-screw expander, including body, is provided with a main shaft in described body, the outer surface of described main shaft is provided with one
Screw rod, the axial of described screw rod is respectively provided on two sides with the star-wheel engaged, the star-wheel of the axial side of described screw rod
Upward, the addendum flank of the star-wheel of the axial opposite side of described screw rod is down for addendum flank, it is characterised in that: the gear teeth of described star-wheel
Tooth on front side of bus to the distance of described addendum flank be H1, on rear side of the tooth of the gear teeth of described star-wheel bus to described addendum flank away from
From for H2, on front side of described tooth, bus is L1 with the contact length of the screw channel of described screw rod, bus and described screw rod on rear side of described tooth
The contact length of screw channel be L2, wherein, and H1 × L1 ＜ H2 × L2, the tooth of the screw channel of described screw rod and the gear teeth of described star-wheel
Shape matches.
As further improvement of the present utility model, described screw rod is six screw rods, and described star-wheel comprises 11 gear teeth.
The beneficial effects of the utility model are: before the tooth of the gear teeth of the star-wheel of a kind of single-screw expander of the present utility model
Side bus is less than distance H2 of bus extremely described addendum flank on rear side of the tooth of described star-wheel to distance H1 of described addendum flank, and described
On front side of the tooth of the gear teeth of H1 and star-wheel, bus and the product of the contact length L1 of the screw channel of described screw rod are less than described H2 and star-wheel
The gear teeth tooth on rear side of bus to the product of distance H2 of described addendum flank so that the aerodynamic force square of star-wheel gear teeth both sides is just
Value, decreases the mechanical loss of screw motion, reduces the energy consumption of single-screw expander, can reduce the mill of the gear teeth of star-wheel simultaneously
Damage, improve the life-span of star-wheel.
Accompanying drawing explanation

Fig. 2 is the sectional view that the gear teeth of star-wheel of the present utility model engage with the screw channel of screw rod；
Fig. 3 is the Local map that the star-wheel gear teeth of the present utility model engage with screw channel.
Detailed description of the invention
With detailed description of the invention, this utility model is described in further detail below in conjunction with the accompanying drawings, however, it is desirable to say
Bright, the explanation to implementation below is schematic, is not intended that concrete restriction of the present utility model.
With reference to Fig. 1, a kind of single-screw expander of the present utility model includes body 2, is provided with a main shaft 3 in body 2, main
The outer surface of axle 3 is provided with a screw rod 1, and screw rod 1 is six screw rods, and the axial both sides of described screw rod 1 are respectively arranged with and it
Engagement star-wheel 5, star-wheel 5 comprise 11 teeth, the addendum flank 10 of the star-wheel 5 of the axial side of screw rod 1 upward, opposite side
Star-wheel 5 addendum flank 10 down.Being only preferred embodiments of the present utility model, screw rod 1 is not limited to six with the combination of star-wheel 5
Head screw rod and the combination of 11 dental stars wheel, it is also possible to the combination taken turns for four-head screw rod and six dental stars or six screw rods and nine dental stars wheel
Combination etc..
With reference to Fig. 2 and Fig. 3, on front side of the tooth of the gear teeth of described star-wheel 5, bus 8 is H1 to the distance of described addendum flank 10, in
On rear side of the tooth of described star-wheel 5, bus 9 is H2 to the distance of described addendum flank 10, bus (8) and described screw rod (1) on front side of described tooth
The contact length of screw channel be L1, on rear side of described tooth, bus (9) is L2 with the contact length of the screw channel of described screw rod (1), wherein,
And H1 × L1 ＜ H2 × L2, due to screw channel and the wheel of the gear teeth meshing of star-wheel 5, the screw channel of screw rod 1 and described star-wheel 5 of screw rod 1
The profile of tooth of tooth matches.In the operation process of a kind of single-screw expander of the present utility model, in the overall process of gas expansion
In due to each gear teeth of star-wheel 5, and H1 × L1 ＜ H2 × L2, on rear side of the tooth of the gear teeth of star-wheel 5, the gas force of 12 is more than star
The gas force of 11 on front side of the tooth of the wheel gear teeth, so that the gas moment of two flanks on the gear teeth of this star-wheel is on the occasion of, and institute
Having the gas moment of two flanks of the gear teeth engaged with screw channel is all on the occasion of, two flank gases of the gear teeth of the most multiple star-wheels 5
The resultant moment of power becomes the kinetic moment of star-wheel 5, and such star-wheel 5 rotates under the effect of gas force kinetic moment, and pushes away without screw rod 1
Dynamic, on the one hand reduce the mechanical loss of screw rod, improve the work efficiency of single-screw expander, on the other hand also improve star-wheel
Life-span.
The foregoing is only preferred embodiments of the present utility model, as long as realizing this utility model with essentially identical means
Within the technical scheme of purpose broadly falls into protection domain of the present utility model.
