The stator 1 is preferably engaged by screw thread with rotor 2.
The preferred screw rod of the rotor 2；One end that the rotor 2 is in contact with axial end where bearing is preferably arranged to cone
Shape, to facilitate and shaft end positioning and close contact where bearing.
The secure component 3 preferably includes two semicircle components, is connected by screw rod screw between two semicircle components.
When using, two screw rod screws of fastening can be just held on bearing inner race two semicircle components tightly.
The articulating members 4 preferably include two or more flexible connection sub-units 5.It is described two or two
Connection site of the individual flexible connection sub-unit 5 above on stator 1 and secure component 3 is uniformly distributed in axial direction.
The flexible connection preferred hinge member 6 of sub-unit 5.
The hinge member 6 preferably includes connection sheet 7 and connecting rod 8, and the upper and lower ends of the connection sheet 7 pass through screw rod respectively
