Abstract
The utility model provides a double tapered single screw structure of a 200m<3> air compressor, which comprises a shell, a front end cover, a rear end cover and a main shaft. The main shaft is connected with two screws, each screw is respectively meshed with a group of star wheel pieces, the shell is composed of two independent inner tapered shells, the two inner tapered shells are connected and sealed together by an intermediate body, two sides of the intermediate body and two ends of the main shaft are respectively provided with bearings, the two screws both are tapered screws and are arranged symmetrically, moreover, the inner tapered shells, the tapered screws and the star wheel pieces form an enclosed space for compressing air. According to the double tapered single screw structure, a structure that the two tapered screws are driven by one main shaft is adopted, the linear velocities of the screws and the star wheels are lowered, and thus, the structure size of the single screw compressor with th specification being 200m<3>/min is reduced; the double tapered single screw structure of the 200m<3> air compressor fills a national gap in a single screw air compressor with the specification being 200m<3>/min, and solves the defects of big volume and high specific power of an existing structure.
Description
Technical field
The utility model relates to a kind of compressor list screw-rod structure, belongs to air compressor technical field.
Background technique
At present, common single screw air compressor maximum pump discharge is not more than 100m
3/ min, because screw rod and the star-wheel size of single screw compressor are larger, under high revolution, the linear velocity of screw rod and star-wheel is higher, is difficult to guarantee that screw rod and star-wheel normally move, so volume flow is greater than 100m
3the single screw compressor of/min has been subject to limitation.
Model utility content
For above deficiency, the utility model provides a kind of 200 vertical air compressor Double-conical-surface list screw-rod structures.
The technical solution of the utility model: 200 vertical air compressor Double-conical-surface list screw-rod structures, comprise housing, front cover, rear end cover and main shaft, wherein on main shaft, be connected with two screw rods, each screw rod meshes with one group of spider piece respectively, described housing is comprised of two independent inner conical surface housings, two inner conical surface housings connect sealing by intermediate, the both sides of intermediate and the two ends of main shaft are separately installed with bearing, described two screw rods are conical surface screw rod and symmetrical placement, by inner conical surface housing, conical surface screw rod, spider piece three forms the confined space that air is compressed.
The beneficial effects of the utility model: the utility model, by adopting a main shaft to drive the structure of two conical surface screw rods, has reduced the linear velocity of screw rod and star-wheel, thereby reduced 200m
3the physical dimension of/min single screw compressor; The utility model has been filled up single-screw air compressor 200m
3the country of/min structure is blank, solves the deficiency that existing structure volume is large, specific power is high, is the innovation of compressor integral structure.
Accompanying drawing explanation
Fig. 1 is structural representation one of the present utility model.
Fig. 2 is structural representation two of the present utility model.
Embodiment
As depicted in figs. 1 and 2,200 vertical air compressor Double-conical-surface list screw-rod structures, comprise housing 2, front cover 5, rear end cover 8 and main shaft 4, wherein on main shaft 4, be connected with two screw rods 3, each screw rod 3 meshes with one group of spider piece 1 respectively, described housing 2 is comprised of two independent inner conical surface housings, and two inner conical surface housings connect sealing by intermediate 6.The both sides of intermediate 6 are provided with ball bearing, and the two ends of main shaft 4 adopt roller bearing for supporting, all for supports main shaft 4.Described two screw rods 3 are conical surface screw rod and symmetrical placement.By inner conical surface housing, conical surface screw rod 3, spider piece 1 three, form the confined space that air is compressed.
During work, drive motor drives main shaft 4 rotations by coupling, thereby drive two conical surface screw rods 3 on main shaft 4 to rotate, the spider piece 1 on conical surface screw rod 3 both sides is along with 3 of conical surface screw rod rotates and rotates along screw slot, by because inner conical surface housing, conical surface screw rod 3, spider piece 1 three form the confined space that air is compressed, therefore along with the rotation of conical surface screw rod 3, spider piece 1, sealed volume is constantly dwindled, and forms compression exhaust process.
