Sleeve assembly and axial thrust disk, the machine shaft are fixed on axial thrust disk, and it passes through Upper shaft sleeve component and lower axle
Set component is located in outer housing；The Lower shaft sleeve component is connect with supporting bead；The stator coil component and p-m rotor
Component is used cooperatively, and the machine shaft is used cooperatively with permanent magnet rotor component；The both ends of the stator coil component are fixed and are set
It is equipped with electrical-coil bushing, stainless steel housing, the electricity are provided between the stator coil component and permanent magnet rotor component
Inner tank mouths and exterior notch are offered on machine coil bushing respectively, O-ring seal is respectively arranged in the inner tank mouths and exterior notch,
O-ring seal in the inner tank mouths is bonded with the peripheral surface of stainless steel housing, the O-ring seal in the exterior notch with it is outer
The inner wall of shell is bonded；Electrical-coil bushing of the both ends of the stainless steel housing respectively with portion disposed thereon and lower part is fixed
Connection makes stator coil component form seal operation space..
The peripheral surface of the supporting bead opens up fluted, and O-ring seal, the O-shaped sealing are provided in the groove
Circle is bonded with the inner face of outer housing.
With the above structure, the utility model is compared to the prior art advantageously：The utility model passes through
Stator coil component coordinates with permanent magnet rotor component, and the penetration power in magnetic field is stronger, can be produced in this way with thicker stainless steel screen
Set is covered, then is sealed by O-ring seal, this structure compares its existing simple for process, of low cost, working efficiency
Height, and good supporting force and repair are more convenient.
