Title
(EN) Water pump motor rotor structure with rotating shaft
(ZH) 一种带转轴的水泵马达转子结构
Abstract
(EN)
The utility model discloses a water pump motor rotor structure with a rotating shaft. The water pump motor rotor structure comprises a rotor main body, an upper porcelain bushing, a lower porcelain bushing, magnets, water blades, the rotating shaft and a rotor shaft core, the rotor shaft core is sleeved on the rotating shaft, the magnet is sleeved on the rotor shaft core, the rotor main body wrapsthe magnet, the rotating shaft and the rotor shaft core, and two ends of the rotating shaft penetrate out of the rotor main body. Wherein the upper porcelain bushing and the lower porcelain bushing are fixed on a water pump shell, the upper porcelain bushing forms an upper bushing hole, the lower porcelain bushing forms a lower bushing hole, and axes of the upper bushing hole and the lower bushing hole are positioned on the same straight line; two ends of the rotating shaft are rotatably matched with the upper and lower sleeve holes; water blades are fixed to the end of the rotor body. The magnets and the rotating shaft are separated through the rotor shaft core and kept relatively fixed, so that the concentricity of the magnets and the rotating shaft is ensured; the upper porcelain bushing and the lower porcelain bushing are fixed on the water pump, the concentricity of the upper porcelain bushing and the lower porcelain bushing is corrected through a tool, the concentricity of the upper porcelain bushing and the lower porcelain bushing is guaranteed, the upper porcelain bushing, the lower porcelain bushing, the magnet and the rotating shaft have high concentricity, vibration andabrasion during rotor use can be reduced, and the service life is prolonged.
