Description
Technical field：
The present invention relates to the device for moving the rotation on job platform, transmission and driving under water.
Background technology：
At present, job platform drive device is moved under water substantially by the way of motor drives propeller, is had for sealing means
Two kinds, a kind of is to be full of turbine oil in motor casing or seal closure to prevent the entrance of water；Another way uses the O-shaped rubber of multiple tracks
Sealing ring mode, even with full of turbine oil seal form also will by means of the O-shaped rubber seal of multiple tracks mode.Work as O
Type rubber seal shaft contacts friction when with being damaged, and turbine oil will be leaked out or water enters in turbine oil seal cavity,
Reducing the insulaion resistance of motor causes burn-down of electric motor.It is more and more deeply, anxious in this area as underwater operation is more and more
Need a kind of good seal performance, can long-lived device under water.
The content of the invention：
The present invention is directed to propose a kind of double magnet ring driving sealing devices of synchronization, fundamentally solve the skill in the presence of prior art
Art problem, it is characterized in that, the reductor with motor, which is fixed in the above, mounting flange platform, inner magnetic cavity cylinder and inner magnetic cavity flange
Inner magnetic cavity center on, reductor shaft is penetrated in inner magnetic cavity by axis hole, uniform 8~12 fixed spiral shells on mounting flange platform
Hole, the motor cover with sealing sheath is fixed on the outside of motor and speed reducer, and control feed cable is passed through sealing sheath,
First even number is divided to be fixed on interior magnetic disk with magnet screw etc. 8~24 blocks of internal magnets, every two blocks of adjacent internal magnets are with interior branch dividing plate
Separate, the interior magnetic disk with even numbered blocks internal magnet is fixed on reductor shaft with key block, back-up ring and axle screw, outside internal magnet
Surface is 0.5~1.0mm with inner magnetic cavity tube inner surface gap value, and the inner magnetic cavity lid with interior axle is fixed on interior magnetic with fixing screws
On cell method orchid, left side wall with posting rubber wheel on 6~8 sealing outer bearings, outer magnetic cavity wheel and internal equipped with 8~24 blocks of outer magnetic
The outer magnetic cavity that turns of iron is inserted in outside inner magnetic cavity, and 6~8 sealing outer bearing outers are contacted with inner magnetic cavity outer round surface, external magnet number
Identical with internal magnet number, the N of external magnet is extremely corresponded to be isolated between the S poles of internal magnet, adjacent external magnet with outer branch dividing plate,
External magnet inner surface and inner magnetic cavity tube outer surface gap value are 0.5~1.0mm, in outer bearing sleeve equipped with inboard bearing and outside
The outer shaft-cup of side bearing is inserted in interior axle by inboard bearing and outboard-bearing hole one end, and the other end of outer shaft-cup is solid with fixing screws
It is scheduled on the right side of outer magnetic cavity wheel, interior shaft end is fixed on axle key screw back-up ring, with fixed screw by end cap flange with connection
The end cap of axle is fixed on bearing sleeve flange.Wherein motor cover and inner magnetic cavity closing face and inner magnetic cavity lid and inner magnetic cavity flange
Conjunction face there is painting fluid sealant.To ensure submerged depth, inner magnetic cavity is set not intake under this depth, while to control power supply electricity
Cable have also been made high-grade encapsulation process with sealing sheath.Turn on magnetic cavity internal diameter to prevent silt from entering external magnet equipped with sealing ring outside
In gap between inner surface and inner magnetic cavity tube outer surface, interior magnetic disk is carried out spacing solid with interior magnetic disk set, back-up ring and axle screw
It is fixed, coupled using key block with reductor shaft.Inboard bearing and outboard bearing use inner side spider, interior axle spider, back-up ring and axle spiral shell
Silk is fixed, and fluid sealant is scribbled between bearing sleeve flange face and end cap flange face.
What the technical scheme that the present invention is provided was realized has the technical effect that such：By controlling feed cable to make motor with deceleration
Machine is rotated, and rotating speed and rotation direction can control.When motor is rotated, reductor shaft will be driven in 8~24 pieces by interior magnetic disk
Magnet rotors, because the S poles of 8~24 blocks of internal magnets are corresponded with the N poles of 8~24 blocks of external magnets, while inner magnetic cavity cylinder is used
Non- NULL is made, according to the attracting principle of magnet opposite pole, and 8~24 blocks of external magnets will turn with 8~24 blocks of internal magnets
Move and rotate, 8~24 blocks of external magnets will drive the outer outer magnetic cavity wheel and outer shaft-cup turned on magnetic cavity to rotate together.6~8 sealings are outer
Bearing and inboard bearing and outboard bearing ensure that the outer concentricity for turning magnetic cavity internal diameter and inner magnetic cavity cylinder external diameter.Due to 8~24 blocks of outer magnetic
The gap value of iron inner surface and inner magnetic cavity tube outer surface, 8~24 pieces of internal magnet outer surfaces and inner magnetic cavity tube inner surface is both designed as
0.5~1.0mm, inner magnetic cavity barrel thickness is 3~5mm, and inside and outside magnet is made of Nd-Fe-B permanent magnet, therefore transmission torque
It is very big.If be hoofing part from the present apparatus, so that it may fix rubber wheel on outer magnetic cavity wheel, pass through mounting flange
Several fixing threaded holes on platform are fixed on below walking arrangement；Such as it is used for the driver element of other manner under water from the present apparatus,
Synchronizing wheel, sprocket wheel and other connectors can be loaded onto on coupling spindle.
The present invention provides a perfect technical scheme for underwater operation equipment, and the technical program is novel, smart structural design,
Rationally, underwater sealing performance is good, and transmission torque is big, with novelty, creative and practicality, will be widely used in setting under water
The field such as standby.
