Or controllable torque is provided and is adjusted with controlling research equipment to needing position and angle etc..
The push system that common aircraft uses is to pass through coupling of shaft system propeller rotation catheter combination with from motor
It uses.In profundal zone when operation, generally requires by filling pressure compensation mode inside propeller and balance the pressure of external water, together
When by shafting rotatory sealing to prevent water from entering.
The earlier patent application of the following contents such as disclosed, and application number CN201410637179.1 is entitled to have rotary collecting
The Quan Haishen brush-less Dc motor propeller of dress formula mechanical seal uses brshless DC motor to drive ducted propeller, shafting
Sealing is realized by one group of special rotation integrated mechanical sealing device.But such mechanical seal structure, after long-time
The leakage that can lead to pressure compensation liquid because of abrasion, does not finally have sealing effect and water is caused to enter inside motor, easily lead
It sends a telegraph the damage of pushing system component and fails.
For another example following earlier application patent, application number CN201210355036.2, a kind of small underwater magnetic coupling of title push away
Into device device, scheme, which is DC motor drives case, drives external propeller by Magnetic Pole Coupling, outside entire motor
Shell seal with O ring.If such sealing device is used for deepwater regions, the thickness of magnetic shield must be increased, then correspondingly increased
Propeller self weight, it is clear that be unfavorable for carrying out the adjustment of propeller oneself state and angle in the biggish deepwater regions of hydraulic pressure.
Meanwhile being analyzed from the bearing jointing structure of Magnetic Pole Coupling inner and outer Rotator, necessarily it is not suitable for biggish load, therefore
The limitation of above-mentioned sealing means is larger, can not be applicable to deepwater regions compared with high thrust.
In view of this, special propose present patent application.
