The invention relates to an underwater shaftless propeller which is provided with a stator assembly, a rotor assembly and a blade set. The stator assembly comprises a tubular casing, wherein a stator winding is fixedly arranged on the inner wall of the casing. The rotor assembly comprises a tubular rotor body, and a magnetic steel group is fixedly arranged on the outer wall of the tubular rotor body; the stator winding and the magnetic steel group are sealed through glue pouring. A blade group is fixedly arranged on the inner wall of the rotor body; the casing is arranged outside the rotor body, and the stator winding and the magnetic steel group are both located between the casing and the rotor body; the two ends of the rotor body are rotationally connected with the machine shell through a first bearing assembly and a second bearing assembly correspondingly. The fit clearances from the first bearing assembly and the second bearing assembly to the stator winding or the magnetic steel group have a plurality of changing paths. Sediment can be effectively prevented from entering, so that abrasion and damage to glue pouring of the stator winding and the magnetic steel group caused by the silt are effectively avoided, and the service life of a product is prolonged.

    本发明涉及一种水下无轴推进器,具有定子总成、转子总成以及叶片组;所述定子总成包括内壁上固定设有定子绕组的管壳状的机壳;所述转子总成包括外壁上固定设有磁钢组的管壳状的转子体;所述定子绕组和磁钢组灌胶密封;转子体的内壁上固定设有叶片组;所述机壳设置在转子体的外部,且定子绕组和磁钢组均位于机壳与转子体之间;转子体的两端分别通过第一轴承组件和第二轴承组件与机壳转动连接;第一轴承组件和第二轴承组件至定子绕组或磁钢组的配合间隙均具有多个变化的路径。本发明能够有效防止泥沙进入,从而有效避免泥沙对定子绕组和磁钢组的灌胶造成磨损和破坏,提高产品使用寿命。
