Description
Technical field
The present invention relates to a kind of single-screw expander, especially a kind of energy-efficient single-screw expander.
Background technology
The distance of busbar to the addendum flank of star-wheel is equal to the tooth of star-wheel on front side of the tooth of the star-wheel of existing single-screw expander
Rear side busbar is to the distance of the addendum flank of star-wheel, and phase, length of the star-wheel tooth front side busbar in screw channel are more than star-wheel before inflation
Length of the busbar in screw channel on rear side of tooth, so that the gas torque on two flank of star-wheel is negative value, phase upon inflation, star
Length of the busbar in screw channel is less than length of the busbar in screw channel on rear side of star-wheel tooth on front side of the gear teeth so that on two flank of star-wheel
Gas torque be on the occasion of, but due to expansion early period star-wheel two flanks gas torque ratio expansion the 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 is moved as expanding machine
The moment of resistance, therefore increase the mechanical loss of screw rod, influence the efficiency of expanding machine, while can also aggravate the mill of the gear teeth of star-wheel
Damage.
The content of the invention
To solve the above-mentioned problems, high it is an object of the invention to provide a kind of work efficiency, the single screw rod of long lifespan is swollen
Swollen machine.
The present invention is for the technical solution that uses of its technical problem of solution：
A kind of single-screw expander, including body, the body is interior to be equipped with a main shaft, and the outer surface of the main shaft is equipped with one
Screw rod, the axial both sides of the screw rod are respectively equipped with the star-wheel engaged, the star-wheel of the axial side of the screw rod
Upward, the addendum flank of the star-wheel of the axial opposite side of the screw rod is downward for addendum flank, it is characterised in that：The gear teeth of the star-wheel
Tooth on front side of the distance of busbar to the addendum flank be H1, the tooth rear side busbar of the gear teeth of the star-wheel to the addendum flank away from
From for H2, the contact length of busbar and the screw channel of the screw rod be L1 on front side of the tooth, busbar and the screw rod on rear side of the tooth
The contact length of screw channel be L2, wherein, and H1 × L1 ＜ H2 × L2, the tooth of the screw channel of the screw rod and the gear teeth of the star-wheel
Shape matches.
Further as the present invention improves, and the screw rod is six screw rods, and the star-wheel includes 11 gear teeth.
The beneficial effects of the invention are as follows：A kind of tooth front side busbar of the gear teeth of the star-wheel of single-screw expander of the present invention is extremely
The distance H1 of the addendum flank is less than on rear side of the tooth of the star-wheel busbar to the distance H2 of the addendum flank, and the H1 and star-wheel
The gear teeth tooth on front side of the product of contact length L1 of screw channel of busbar and the screw rod be less than the gear teeth of the H2 and star-wheel
On rear side of tooth busbar to the distance H2 of the addendum flank product so that the aerodynamic force square of star-wheel gear teeth both sides is on the occasion of reducing
The mechanical loss of screw motion, reduces the energy consumption of single-screw expander, while can reduce the abrasion of the gear teeth of star-wheel, improves star
The service life of wheel.
Brief description of the drawings
Fig. 1 is a kind of structure diagram of single-screw expander of the present invention；
Fig. 2 is the sectional view that the gear teeth of star-wheel of the present invention are engaged with the screw channel of screw rod；
Fig. 3 is the Local map that the star-wheel gear teeth of the present invention are engaged with screw channel.
Embodiment
The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, however, it is desirable to explanation
It is that the explanation to implementation below is schematical, does not form and the specific of the present invention is limited.
With reference to Fig. 1, a kind of single-screw expander of the invention includes body 2, a main shaft 3, main shaft 3 is provided with body 2
Outer surface one screw rod 1 is installed, screw rod 1 is six screw rods, and the axial both sides of the screw rod 1, which are respectively arranged with, to be engaged
Star-wheel 5, star-wheel 5 includes 11 teeth, the addendum flank 10 of the star-wheel 5 of the axial side of screw rod 1 upward, the star of opposite side
The addendum flank 10 of wheel 5 is downward.The combination of preferred embodiments only of the invention, screw rod 1 and star-wheel 5 be not limited to six screw rods and
The combination of 11 dental star wheels, can also be four-head screw rod and the combination of six-teeth star wheel or the combination of six screw rods and nine dental star wheels etc.
Deng.
With reference to Fig. 2 and Fig. 3, the distance of busbar 8 to the addendum flank 10 is H1 on front side of the tooth of the gear teeth of the star-wheel 5, in
The distance of busbar 9 to the addendum flank 10 is H2 on rear side of the tooth of the star-wheel 5, the spiral shell of busbar 8 and the screw rod 1 on front side of the tooth
The contact length of groove is L1, and busbar 9 and the contact length of the screw channel of the screw rod 1 are L2 on rear side of the tooth, wherein, and H1 × L1
＜ H2 × L2, due to the gear teeth meshing of the screw channel and star-wheel 5 of screw rod 1, the tooth form of the screw channel of screw rod 1 and the gear teeth of the star-wheel 5
Match.In a kind of operation process of single-screw expander of the present invention, due to star-wheel 5 in the overall process of gas expansion
The distance H1 of busbar 8 to the addendum flank 10 is less than on rear side of the tooth of the star-wheel 5 busbar 9 on described on front side of the tooth of each gear teeth
The distance H2 of the flank of tooth 10, and H1 × L1 ＜ H2 × L2, the gas force of the tooth rear side 12 of the gear teeth of star-wheel 5 are more than the tooth of the star-wheel gear teeth
The gas force of front side 11, so that the gas torque of two flanks on the gear teeth of the star-wheel is on the occasion of and all being nibbled with screw channel
The gas torque of two flanks of the gear teeth of conjunction is all on the occasion of therefore the resultant moment of two flank gas forces of the gear teeth of multiple star-wheels 5
As the kinetic moment of star-wheel 5, such star-wheel 5 rotates under the action of gas force kinetic moment, is promoted without screw rod 1, on the one hand
The mechanical loss of screw rod is reduced, improves the work efficiency of single-screw expander, on the other hand also improves the service life of star-wheel.
The foregoing is merely the preferred embodiments of the present invention, as long as realizing the skill of the object of the invention with essentially identical means
Art scheme is belonged within protection scope of the present invention.
