Title
(EN) Adjustable water pump motor rotor structure
(ZH) 一种可调整的水泵马达转子结构
Abstract
(EN)
The utility model discloses an adjustable water pump motor rotor structure which comprises a rotor main body, an upper porcelain bushing, a lower porcelain bushing, magnets, water blades and a lower porcelain bushing shell, and the rotor main body comprises a first rotor main body and a second rotor main body; an upper porcelain bushing mounting through hole, a lower porcelain bushing mounting through hole and a rotating shaft through hole for a rotating shaft of the motor to penetrate through are formed in the first rotor main body; two ends of the rotating shaft through hole are respectivelycommunicated with the upper porcelain bushing mounting through hole and the lower porcelain bushing mounting through hole; an upper porcelain bushing is arranged in the upper porcelain bushing through hole, a lower porcelain bushing shell is arranged in the lower porcelain bushing through hole, and the lower porcelain bushing shell is sleeved on the surface of the lower porcelain bushing; the magnet is sleeved on the periphery of the first rotor body, the second rotor body is sleeved on the periphery of the magnet and the first rotor body, and water blades are fixed at the end of the second rotor body. According to the utility model, the lower porcelain bushing shell is arranged between the first rotor main body and the lower porcelain bushing as a buffer medium, so that when the concentricity of the upper porcelain bushing and the lower porcelain bushing is poor, the concentricity can be adjusted, the product wear is reduced, and the service life is prolonged.
