| titleOfInvention | Impeller anti-abrasion structure on water pump |
| abstract | The utility model discloses an impeller anti-abrasion structure on a water pump, which comprises a motor, a bracket and a pump body, wherein the motor comprises a shell, a stator, a rotor and a rotating shaft connected to the center of the rotor, and the rotating shaft sequentially comprises a first shaft section, a second shaft section, a third shaft section, a fourth shaft section, a fifth shaft section and a sixth shaft section from bottom to top; the cross section of the fifth shaft section is a closed path formed by three equal-length circular arcs and three equal-length line sections which are connected end to end at intervals, and the three circular arcs are arc sections on the same circle; the shape of the shaft hole in the center of the impeller is matched and butted with that of the fifth shaft section, and the size of the shaft hole is larger than that of the fifth shaft section; the sixth shaft section is provided with an external thread, and the fastening nut is screwed on the sixth shaft section; the outer end of the shaft hole of the impeller is provided with a step hole, the inner end of the fastening nut is provided with a raised step, and the raised step is inserted into the step hole in a matching manner. The utility model discloses a processing degree of difficulty is low, and low in production cost can effectually prevent impeller axial displacement, wearing and tearing, improves the stability of impeller assembly back operation. |
