Abstract
An impeller mounting structure of an impeller machine comprises an impeller and a drive shaft. The impeller and the drive shaft are pressed and fixed through a double-thread screw and a locking nut. The end faces, matched with the drive shaft, of the impeller are respectively provided with an end face tooth, and the end face teeth are meshed. The impeller mounting structure mainly solves the problems that the impeller machine easily looses in a working state of long-term high-speed rotation, in this way, long-term stable operation cannot be guaranteed, and safety is low. The impeller mounting structure has the advantages that as the end face teeth are meshed, the linkage match between the drive shaft and the impeller is further guaranteed; the impeller mounting structure is not only simple in structure but also high in stability, long in life and high in safety.
Description
Technical field
The utility model relates to a kind of turbomachine, is specifically related to a kind of impeller installing of turbomachine.
Background technique
In quick runner machinery, turbine or impeller High Rotation Speed, bear huge centrifugal force and air-flow impulsive load in working order, and mounting type is the important guarantee of turbomachine operation steady in a long-term reliably.
But in existing turbomachine, only generally that impeller and live axle are fixed by double threaded screw, locking nut, under such working state that is engaged in the long-term High Rotation Speed of impeller, easily loosening, thereby cannot ensure operation steady in a long-term, and poor stability.
Model utility content
In order to overcome the deficiency of background technique, the utility model provides a kind of impeller installing of turbomachine, solves existing turbomachine under the working state of long-term High Rotation Speed, easily loosening, thereby cannot ensure operation steady in a long-term, and the problem of poor stability.
The technological scheme that the utility model adopts: a kind of impeller installing of turbomachine, comprise impeller, live axle, described impeller, live axle are fixed by double threaded screw, locking nut; On the end face that described impeller matches with live axle, be equipped with end-tooth, and intermeshing.
The profile of tooth of described end-tooth is radially wedge shape.
The tooth-shape angle of described end-tooth is 60 °.
The beneficial effects of the utility model are: adopt above scheme, utilize end-tooth intermeshing, further ensured being linked between live axle and impeller, and not only simple in structure, and also stability is strong, and the life-span is high, and margin of safety is high.
Brief description of the drawings
Fig. 1 is the utility model example structure schematic diagram.
Fig. 2 is the structural representation of the utility model embodiment end-tooth.
1-double threaded screw in figure, 2-locking nut, 3-impeller, 4-live axle, 5-end-tooth.
Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is described further:
As shown in Figure 1, an impeller installing for turbomachine, comprises impeller 3, live axle 4, and described impeller 3, live axle 4 are fixed by double threaded screw 1, locking nut 2, on the end face that described impeller 3 matches with live axle 4, be equipped with end-tooth 5, and intermeshing.
Utilize end-tooth 5 intermeshing, further ensured being linked between live axle 4 and impeller 3, not only simple in structure, and also stability is strong, and the life-span is high, and margin of safety is high.
Wherein the profile of tooth of end-tooth 5 is radially wedge shape, and tooth-shape angle is 60 °, and wedge-shaped surface realizes the pressure locking of impeller, the flank of tooth has higher carrying percentage, and repeatability is high, and can self-alignment, ensured axially and circular runout little, make work more stable.
Claims (3)
