Description
Technical field
The utility model is related to a kind of helm gear, especially a kind of waterproof steering engine.
Background technology
General steering engine is made of motor, control circuit, reduction gearing, angular transducer, and these components cannot intake, because
This needs sets sealing device between these components and output shaft.Since output shaft is to rotate, general anti-water rudder
Machine needs are sealed between the output shaft and static shell of rotation, and such to be sealed into dynamic sealing, traditional dynamic sealing is adopted
It is realized with the rubber ring between output shaft and shell is compressed, this method has the advantages of simple in structure, at low cost, but rubber
Circle may influence sealing effect because of long-time abrasion, so as to cause leak, need periodically to recycle steering engine, to be examined
Replacement is looked into, service life is not grown.
Invention content
The technical problem to be solved by the utility model is to provide a kind of water resistance is preferable and can use for a long time anti-
Water rudder machine.
Technical solution is used by the utility model solves above-mentioned technical problem：A kind of waterproof steering engine, including capsul
Body, driving steering engine and output shaft, the driving steering engine are fixed in the seal casinghousing, and the driving steering engine leads to
Magnetic hitch bar and the output axis connection are crossed, the magnetic hitch bar is same successively including shaft coupling and from outside to inside
Magnetic outer rotor, waterproof separation sleeve and the magnetic internal rotor of axis distribution, the end of the magnetic outer rotor passes through the connection
Axis device is fixedly connected with the drive shaft of the driving steering engine, is set between the waterproof separation sleeve and the seal casinghousing
There is the first waterproof grommet, the magnetic internal rotor is provided with mounting hole, and one end of the output shaft is fixed at institute
In the mounting hole stated, the other end of the output shaft stretches out the seal casinghousing, the output shaft and the sealing
Bearing is provided between housing.
The seal casinghousing includes the sealed compartment and sealing flange that are tightly connected, the sealed compartment and the sealing
The second waterproof grommet is provided between flange, the waterproof separation sleeve is fixedly connected with the sealing flange, described
First waterproof grommet is arranged between the waterproof separation sleeve and the sealing flange, and the sealing flange is provided with
Mounting hole, the bearing are fixed in the mounting hole, and the output shaft passes through the bearing and to overhanging
Go out the mounting hole.
Spacer pin is provided on the output shaft, restraining position ring block, the spacing ring are set on the sealing flange
On be provided with limiting slot, the end of the spacer pin is stretched into the limiting slot.When output shaft is by excessive external work
Firmly, when making the active force of the magnetic magnetic outer rotor of internal rotor disengaging and having skidded phenomenon, due to the rotational angle of spacer pin
It is limited by limiting slot, therefore preferable protective effect is played to the operating of device.
Mounting bracket is vacantly provided in the sealed compartment, the driving steering engine is fixed at the installation branch
On frame.When water is penetrated into sealed compartment, driving steering engine is made to be not directly contacted with water, further protection driving steering engine.
Compared with prior art, the utility model has the advantage of pass through shaft coupling band during the drive shaft turns of driving steering engine
Dynamic magnetism outer rotor rotation, magnetic internal rotor follow rotation under the magnetic coupling interaction power of magnetic outer rotor, are stretched out so as to drive
The output shaft normal rotation work of seal casinghousing, overall structure uses the working method that drive shaft is detached with output shaft, by anti-
Water segregation, which covers the first waterproof grommet set between seal casinghousing, prevents the water of outside from entering inside seal casinghousing, due to anti-
Water segregation set is fixed, static seal is formed between seal casinghousing, therefore waterproof effect is preferable, ensure that driving steering engine
Safety, improve service life.
