Abstract
A kind of underwater propeller magnetic seal driving device, including internal rotor and outer rotor, the internal rotor is fixedly mounted in the drive shaft of underwater propeller, the right end of the shell of the underwater propeller is set with fixed ring, the periphery of the internal rotor is non-contact to be set with the closed separation sleeve of left end opening right end, and separation sleeve left end is installed on by the shoulder having thereon between fixed ring and the shell of underwater propeller, and pass through the housing seal of sealing ring and underwater propeller；The drive shaft right end is mounted on separation sleeve right end inner cavity, the non-contact periphery for being sleeved on separation sleeve of the outer rotor by first bearing, and the left end of outer rotor is inserted into fixed ring, and right end is mounted on the right end of separation sleeve by second bearing；It is evenly distributed blade on the outer wall of the outer rotor.The utility model realizes No leakage substantially, improves the reliability and service life of underwater propeller.
Description
Technical field
The utility model belongs to underwater propeller technical field, more particularly to a kind of underwater propeller magnetic seal driving dress
It sets.
Background technology
One of the critical issue of underwater propeller development is exactly the sealing of drive shaft, i.e., drive shaft stretches out underwater propeller shell
External sealing, traditional underwater propeller use movable sealing structure, and such scheme is limited by Underwater Pressure, it is difficult to accomplish nothing
Leakage increases when depth under water increases pressure, in drive shaft turns, gap is just will appear between drive shaft and shell, is easy
Leakage is generated, underwater propeller is made to break down.
Utility model content
The utility model provides a kind of underwater propeller magnetic seal driving device, and drive shaft stretches out underwater propeller shell
External sealing uses static seal, and transmits torque by magnetic coupling, realizes the non contact transmission of power, basic to realize that nothing is let out
Leakage, improves underwater propeller reliability and service life.
Technical solution used by the utility model is：A kind of underwater propeller magnetic seal driving device, including interior turn
Son and outer rotor, the internal rotor are fixedly mounted in the drive shaft of underwater propeller, the right side of the shell of the underwater propeller
End cap is equipped with fixed ring, and the periphery of the internal rotor is non-contact to be set with the closed separation sleeve of left end opening right end, and separation sleeve
Left end is installed on by the shoulder having thereon between fixed ring and the shell of underwater propeller, and by sealing ring with push away under water
Into the housing seal of device；The drive shaft right end is mounted on separation sleeve right end inner cavity by first bearing, and the outer rotor is non-to be connect
The periphery for being sleeved on separation sleeve is touched, and the left end of outer rotor is inserted into fixed ring, right end is mounted on isolation by second bearing
The right end of set；It is evenly distributed blade on the outer wall of the outer rotor.
The second bearing is ceramic bearing.
Compared to the prior art, the utility model has the advantage that：
1, it is sealed using rubber o-ring when the utility model separation sleeve and underwater propeller shell assemble, fixed ring is used in combination
It is fixed, realizes conversion of the dynamic sealing to static seal；
2, separation sleeve is assembled between the utility model internal rotor and outer rotor to be sealed, ensuring that torque transmission is real simultaneously
The optimization of sealing means is showed.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode
Below in conjunction with the accompanying drawings 1 and specific implementation mode the utility model is described in detail.
A kind of underwater propeller magnetic seal driving device, including internal rotor 5 and outer rotor 6, the internal rotor 5 fix peace
In the drive shaft 2 of underwater propeller, the right end of the shell 1 of the underwater propeller is set with fixed ring 3, the internal rotor
5 periphery is non-contact to be set with the closed separation sleeve 4 of left end opening right end, and 4 left end of separation sleeve passes through the shoulder 7 that has thereon
It is installed between fixed ring 3 and the shell 1 of underwater propeller, and is sealed by the shell 1 of sealing ring 10 and underwater propeller；Institute
It states 2 right end of drive shaft and 4 right end inner cavity of separation sleeve is mounted on by first bearing 8, the outer rotor 6 is non-contact to be sleeved on separation sleeve
4 periphery, and the left end of outer rotor 6 is inserted into fixed ring 3, right end is mounted on the right end of separation sleeve 4 by second bearing 9；
Blade 11 is evenly distributed on the outer wall of the outer rotor 6.The second bearing 9 is ceramic bearing.
Operation principle：Internal rotor of the motor driving equipped with magnet steel rotates, and magnetic force passes through separation sleeve driving outer equipped with magnet steel
Rotor motion realizes the non contact transmission of power, and seals internal rotor by separation sleeve that variation is sealed into static seal, realizes
The movement of No leakage is transmitted.
Above-described embodiment, the only preferred embodiment of the utility model not are used for limiting the implementation model of the utility model
It encloses, therefore all equivalent variations done with content described in the utility model claims, the utility model right should all be included in and wanted
Within the scope of asking.
