Title
(EN) Water pump motor rotor structure capable of being formed once
(ZH) 一种可一次成型的水泵马达转子结构
Abstract
(EN)
The utility model discloses a water pump motor rotor structure capable of being formed at a time. The water pump motor rotor structure comprises a rotor body, an upper porcelain sleeve, a lower porcelain sleeve, magnets, water blades and a rotor shaft core. The rotor shaft core is provided with a shaft core through hole for a motor rotating shaft to pass through. The upper porcelain sleeve and thelower porcelain sleeve are respectively inserted into two ends of the shaft core through hole. An upper sleeve hole and a lower sleeve hole which are arranged along the axial direction of the shaft core through hole are respectively formed in the upper porcelain sleeve and the lower porcelain sleeve and are communicated with two ends of the shaft core through hole; wherein the magnet is sleeved on the rotor shaft core, the rotor main body is sleeved and covered on the peripheries of the upper porcelain bushing, the lower porcelain bushing, the magnet and the rotor shaft core, and two ends ofthe rotor main body are provided with openings communicated with the upper sleeve hole and the lower sleeve hole; the rotor body is formed with water vanes. The upper porcelain bushing and the lower porcelain bushing are connected and fixed through the rotor shaft core, so that the upper porcelain bushing and the lower porcelain bushing are relatively fixed in the radial direction of the rotor shaft core, concentricity of the two is guaranteed, abrasion can be reduced, and service life is prolonged; during production, the rotor body can be formed through one-time injection molding, the production process is simplified, and the product yield and production efficiency are improved.
