Technical field
The utility model relates to the pump technology field, the concrete linkage structure that relates to impeller, slitting wheel and pump shaft in a kind of sewage pump.
Background technique
Along with the development of technology, people are more and more for the needs of cutting type sewage pump.The sewage pump slitting wheel independently are installed on the outside of sewage pump impeller, are connected with water pump spindle, under the drive of pump motor, the fibre object cutting that enters water pump are blended.The installation of cutting device and usage mode have influence on product processing cost and later stage working service cost.
Use traditional keyway Placement in the conventional art, also can be with slitting wheel, impeller and axle link together.Be connected employing " key " Placement between sewage pump shaft, impeller and the slitting wheel.Slitting wheel will reach the cutting effect of cutting type sewage pump, and the gap between slitting wheel and the impeller must be able to freely be adjusted so.Only depend on to prolong the length that axle is gone up keyway, processed complex not only, cost is higher, and the accurately control of also having no idea of the gap between slitting wheel and the impeller, the gap control requirement that does not reach cutting pump.And use the mode of traditional keyway to exist: processed complex, cost height; The gap of slitting wheel and impeller can not free adjustment; Need unload impeller and key simultaneously when replacing or maintenance slitting wheel; Problem such as waste time and energy.
The model utility content
Technical problem to be solved in the utility model is, overcome problems of the prior art, a kind of axle and the linkage structure of impeller and slitting wheel of sewage pump be provided, and this structure has made things convenient for being connected of slitting wheel and sewage pump shaft, makes that the gap between slitting wheel and impeller can freely be adjusted.
In order to address the above problem the technical solution of the utility model is such:
A kind of axle of sewage pump and the linkage structure of impeller and slitting wheel, comprise pump shaft, impeller, slitting wheel, impeller is installed in the pump shaft end, the coaxial installation slitting wheel in the outside of impeller, it is characterized in that the pump shaft end is provided with an axial tapped hole, the slitting wheel center has an axis hole, slitting wheel are bolted to the pump shaft end by one, and bolt passes axis hole and screws in the pump shaft end thread hole.
The pump shaft end has a hoop inclined-plane, and the impeller central inner is provided with the inclined-plane to pump shaft end correspondence, and impeller compresses with pump shaft by the inclined-plane and is connected.
The impeller center is outside to be provided with counterbore near slitting wheel one side, and the slitting wheel center is provided with the projection corresponding with counterbore near impeller one side, fixing in the counterbore on the projection embedding impeller on the slitting wheel.
Described counterbore edge is provided with groove, and the protruding root on the slitting wheel is provided with the small lugs corresponding with groove.
Be provided with pad between described impeller and the slitting wheel.
Inclined-plane processing intracardiac in the beneficial effect, the inclined-plane of pump shaft end described in the utility model and impeller is simpler than keyway processing technology, and cost is lower; Gap between slitting wheel and the impeller can freely be adjusted; Slitting wheel are changed or are easy to maintenance; When slitting wheel or impeller were blocked by hard thing, impeller and slitting wheel can slide from axle, avoided because overload and burn-down of electric motor.
