Make available different capacity, the Agitator Impeller of different performance, but there is a problem of one it is main be exactly that casting impeller can be with
Blade edge is made fillet in a mold to reduce resistance of blade during entering water to promote the working efficiency of blender.
But blade is welded due to being stamping parts, blade edge cannot directly make fillet or chamfering, and blade is this just to impeller
Performance cause influence.
Summary of the invention
The purpose of the utility model is to provide a kind of New agitator impellers.
The utility model will solve that existing cast blade deformation is larger, and yield rate is low, and production cost is big；Weld blade
The problem of blade edge can not directly make fillet or chamfering, influence the performance of impeller.
The technical solution of the utility model is: a kind of New agitator impeller, including blade and wheel hub, the wheel hub
For sphere, the blade, which is centrosymmetric, to be distributed on wheel hub, and the back side on the inlet and outlet side of the blade is equipped with bevel edge；
The front end of the wheel hub is end facing water, and the end facing water is equipped with wheel hub mounted portion, is equipped with and fixes in the wheel hub mounted portion
Keyway；The rear end of the wheel hub is hollow structure.
Preferably, in terms of the direction that meets water of wheel hub, the blade is direction of rotation counterclockwise.
It preferably, is upstream face towards the side of the end facing water of wheel hub on the blade, backwards to the end facing water of wheel hub
It is on one side the back side of upstream face, two sides at the back side of the upstream face of the blade are equipped with bevel edge, and respectively first falls
The arm of angle and the second bevel edge, in terms of the side towards the back side of the upstream face of blade, first bevel edge is set to blade
Side counterclockwise, second bevel edge are set to the clockwise side of blade, the chamfering angle of first bevel edge
Degree is 20 ° ± 1 °, and the chamfer dimesion of second bevel edge is 4 × 30 °, and chamfering length tolerance is IT14, and chamfer angle is public
Difference is ± 1 °, and the edge thickness on the inlet and outlet side of blade is 1, tolerance IT14.
Preferably, the blade is stamping parts, and the wheel hub is cast member, is connected between blade and wheel hub by welding
It connects.
Preferably, the surface of the blade is through pickling processes.
Preferably, the blade is at least two panels.
The utility model has the following beneficial effects: the utility model solves the deficiency of existing Agitator Impeller, casting is avoided
The deformable blade of generation is made, the problem of yield rate is low, high production cost, the blade edge for yet avoiding punching press blade simultaneously can not
The deficiency for making fillet or chamfering reduces the operating power of blender, improves the working efficiency of blender.

Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and embodiments.
As shown, the utility model includes blade 2 and wheel hub 3, the wheel hub 3 is sphere, during the blade 2 is in
The heart is symmetrically distributed on wheel hub 3, and the back side on the inlet and outlet side 6 of the blade 2 is equipped with bevel edge；The front end of the wheel hub 3
For end facing water 7, the end facing water 7 is equipped with wheel hub mounted portion 5, fixed keyway 4 is equipped in the wheel hub mounted portion 5；The wheel
The rear end 9 of hub 3 is hollow structure.It takes turns hub mounted portion 5 and fixed keyway 4 is used for the machine shaft of the utility model and blender
It is fixed.
In the present embodiment, in terms of the direction that meets water of wheel hub 3, the blade 2 is direction of rotation counterclockwise.
In the present embodiment, on the blade 2 towards the side of the end facing water 7 of wheel hub 3 be upstream face 1, backwards to wheel hub 3
The one side of end facing water 7 is the back side 8 of upstream face, and two sides at the back side 8 of the upstream face of the blade 2 are equipped with bevel edge,
Respectively the first bevel edge 10 and the second bevel edge 11, in terms of the side at the back side of the upstream face towards blade 28, described
One bevel edge 10 is set to the side counterclockwise of blade 2, and second bevel edge 11 is set to the clockwise side of blade 2,
The chamfer angle R1 of first bevel edge 10 is 20 ° ± 1 °, and the chamfer dimesion of second bevel edge 11 is 4 × 30 °,
Chamfering length d2 tolerance is IT14, and chamfer angle R2 tolerance is ± 1 °, and the edge thickness d1 on the inlet and outlet side 6 of blade 2 is 1, public
