Abstract
The utility model provides an impeller hub device which comprises an impeller blade disk and an impeller hub. The impeller blade disk is composed of a front disk, a rear disk and impellers, and the front disk, the rear disk and the impellers are welded into a whole. The impeller hub is connected with the rear disk through bolts and is positioned on the bottom of the rear disk. According to the impeller hub device, the rear disk of the impeller blade disk is connected with the impeller hub through the bolts, and thus mechanical strength of the connection between the impeller blade disk and the impeller hub is improved.
Description
Technical field
The utility model relates to a kind of impeller hub device.
Background technique
Existing leaf blade disk is welded to connect by shroud, hub disk, blade and becomes one, hub disk welds with wheel hub and becomes one, because will producing the decay resistance of some distortion and stress and weld seam inevitably, welding do not have the good of integral body yet, so in long-term high speed operation, the weld seam of wheel hub and hub disk stands huge torsion, is easy to generate cracking.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that prior art exists, and a kind of impeller hub device is provided.
The purpose of this utility model is achieved through the following technical solutions:
The impeller hub device, comprise leaf blade disk and impeller hub, described leaf blade disk is made up of shroud, hub disk and blade, described shroud, hub disk and blade pass are crossed to be welded to connect and are integral layout, it is characterized in that: described impeller hub is connected with hub disk by bolt, is positioned at the bottom of hub disk.
Further, above-mentioned impeller hub device, wherein, bolt is also by electric welding fixedly hub disk and impeller hub.
The substantive distinguishing features of technical solutions of the utility model and progressive being mainly reflected in:
Hub disk and impeller hub that the utility model adopts the mode of bolt to connect in the leaf blade disk also adopt spot welding further to fix, improve the mechanical strength that the leaf blade disk is connected with impeller hub, and leaf blade disk and impeller hub can also be detachable, convenient for maintaining and maintenance.
Description of drawings
Below in conjunction with accompanying drawing technical solutions of the utility model are described further:
Fig. 1: organigram of the present utility model.
Embodiment
As shown in Figure 1, the impeller hub device, comprise leaf blade disk 1 and impeller hub 3, leaf blade disk 1 is made up of shroud, hub disk and blade, earlier with blade and the welding of leaf dish shroud, again with leaf dish hub disk welding shroud, its shroud, hub disk and blade pass are crossed be welded to connect and be integral layout, impeller hub 3 is connected with hub disk by bolt 2, is positioned at the bottom of hub disk, and bolt 2 is also by electric welding fixedly hub disk and impeller hub.
Hub disk and impeller hub that the utility model adopts the mode of bolt to connect in the leaf blade disk also adopt spot welding further to fix, improve the mechanical strength that the leaf blade disk is connected with impeller hub, and leaf blade disk and impeller hub can also be detachable, convenient for maintaining and maintenance.
It is emphasized that: above only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment does.
