Embodiment
With embodiment the utility model is described in further detail with reference to the accompanying drawings below:
The utility model provides a kind of cooling waterpump impeller assembly, comprise rotating shaft, impeller and embedded metal part, be sheathed in the described rotating shaft and on the described embedded metal part and fixedly connected with described rotating shaft, described embedded metal part comprises the cylindrical end tangs that is set in its axial external surface, the cross section of described cylindrical end tangs is a polygonal, and described impeller is fixedlyed connected with described embedded metal part by cylindrical end tangs.Because impeller is by polygonal cylindrical end tangs and embedded metal part, when liquid produces tangential force to impeller, impeller also can produce a tangential force to polygonal cylindrical end tangs, each side of cylindrical end tangs produces a reaction force to this tangential force, promptly embedded metal part and impeller joint are produced supporting effect, the tangential force that makes liquid reduces the impact of embedded metal part and impeller Adhesion force, make injection moulding impeller and embedded metal part being not easy disengaging in the radial direction, can not cause the idle running of rotating shaft.
The cross section of cylindrical end tangs can be triangle, quadrilateral and pentagon etc., the processing of embedded metal part for convenience, and under the preferable case, the cross section of described cylindrical end tangs is a Hexagon.
Described embedded metal part is provided with the center hole of axial setting, is used for fixedlying connected with rotating shaft.
One end of embedded metal part is cylindrical, and the other end is taper, and described cylindrical end tangs is between cylindrical end and tapered end.The embedded metal part of roller end will be subjected to the axial impact force of liquid earlier, and the axial impact force that therefore is subjected to liquid is bigger, and the embedded metal part at this place and the Adhesion force of impeller are big, and promptly the area of contact of embedded metal part and impeller needs to increase.So described rotating shaft is passed embedded metal part cylindrical end, cylindrical end tangs and tapered end successively by described axial center hole.Promptly the embedded metal part tapered end near roller end makes the area of contact of embedded metal part and impeller big, and the Adhesion force of embedded metal part and impeller is increased.
The processing of embedded metal part for convenience, the end that embedded metal part tapered end diameter is big is connected with cylindrical end tangs.
As Fig. 3, Fig. 4 and shown in Figure 5, a kind of cooling waterpump impeller assembly, comprise rotating shaft 1, impeller 2 and embedded metal part 3, described embedded metal part 3 is sheathed in the described rotating shaft 1, described embedded metal part 3 is provided with the center hole 35 of axial setting, and rotating shaft 1 is arranged in the axial center hole 35 and with described embedded metal part 3 fixedlys connected.Described embedded metal part 3 comprises the cylindrical end tangs 31 that is arranged on its axial external surface, the cross section of described cylindrical end tangs is a Hexagon 311, one end of embedded metal part is cylindrical, and the other end is taper, and described cylindrical end tangs 31 is between cylindrical end 33 and tapered end 34.Described rotating shaft 1 is passed embedded metal part cylindrical end 33, cylindrical end tangs 31 and tapered end 34 successively by described axial center hole 35.Impeller assembly can be subjected to the axial impact force F3 of liquid at the place, end near rotating shaft 1, embedded metal part tapered end 34 near roller end makes the area of contact of embedded metal part and impeller big, the Adhesion force of embedded metal part 3 and impeller 2 is increased, and embedded metal part 3 is not easy to separate with impeller 2.The end that embedded metal part tapered end 34 diameters are big is connected with cylindrical end tangs 31.
In the process that impeller 2 rotates in liquid, impeller 2 can be subjected to the radially tangential force of liquid, thereby the cylindrical end tangs of 2 pairs of embedded metal parts 3 of impeller 31 can produce tangential force F1, the surface of cylindrical end tangs 31 produces a reaction force F2 to tangential force F1, promptly the joint to embedded metal part 3 and impeller 2 produces supporting effect, tangential force F1 is radially reduced the impact of the Adhesion force of embedded metal part and impeller, and impeller 2 does not break away from embedded metal part 3 easily.
Embodiment by the above is a better embodiment of the present utility model, is not to limit concrete practical range of the present utility model with this, and scope of the present utility model comprises and is not limited to this embodiment; The equivalence variation that all shapes according to the utility model, structure are done all comprises in the protection domain of the present utility model.
