Description

Synchronize double magnet ring driving sealing devices
Technical field:
The present invention relates to for moving the rotation on job platform, transmission and the device of driving under water.
Background technology:
Currently, mobile job platform driving device is substantially in such a way that motor drives propeller under water, for sealing There are two types of modes, and one is be full of turbine oil in motor casing or seal closure to prevent the entrance of water;Another way uses multiple tracks O Type rubber seal mode, even with also will be by means of the side of the O-shaped rubber seal of multiple tracks full of turbine oil seal form Formula.When O-shaped rubber seal is damaged due to shaft contacts friction, turbine oil will leak out or water to enter turbine oil close It seals in cavity, so that the insulation resistance of motor is reduced leads to burn-down of electrical machinery.As underwater operation is more and more, more and more deeply, at this Be badly in need of a kind of good seal performance in a field, can long-lived device under water.
Invention content:
The present invention is directed to propose a kind of synchronizing double magnet ring driving sealing devices, fundamentally solves and deposited in the prior art The technical issues of, characterized in that the speed reducer with motor, which is fixed in the above, mounting flange platform, inner magnetic cavity cylinder and interior magnetic On the inner magnetic cavity center of cell method orchid, reductor shaft is penetrated by axis hole in inner magnetic cavity, uniformly distributed 8~12 on mounting flange platform A fixing threaded hole is fixed on the motor cover with sealing sheath on the outside of motor and speed reducer, and control feed cable is made to pass through Sealing sheath first divides even number to be fixed on interior magnetic disk 8~24 blocks of internal magnets, every two blocks adjacent interior magnetic with magnet screw etc. Iron is separated with interior branch partition board, and interior magnetic disk key block, baffle ring and axis screw with even numbered blocks internal magnet are fixed on speed reducer On axis, internal magnet outer surface is 0.5~1.0mm with inner magnetic cavity tube inner surface gap value, the inner magnetic cavity lid with inner shaft with admittedly Determine screw to be fixed on inner magnetic cavity flange, left side wall is posted with 6~8 sealing outer bearings, on outer magnetic cavity wheel rubber wheel and Outer turn magnetic cavity of the inside equipped with 8~24 blocks of external magnets is inserted in outside inner magnetic cavity, outside 6~8 sealing outer bearing outers and inner magnetic cavity Circular surfaces contact, and external magnet number is identical as internal magnet number, and the N of external magnet extremely corresponds to the poles S of internal magnet, adjacent external magnet it Between be isolated with outer branch partition board, external magnet inner surface and inner magnetic cavity cylinder outer surface gap value are 0.5~1.0mm, in outer shaft Outer shaft-cup equipped with inboard bearing and outboard bearing in bearing sleeve cylinder is inserted in by inboard bearing and outboard-bearing hole one end in inner shaft, The other end of outer shaft-cup is fixed on fixing screws on the right side of outer magnetic cavity wheel, and interior shaft end is fixed on axis key screw baffle ring, with admittedly Determine screw to be fixed on bearing sleeve flange the end cap with coupling spindle by end cap flange.Wherein motor cover and inner magnetic cavity Conjunction face and inner magnetic cavity lid and inner magnetic cavity flange there is conjunction face painting fluid sealant.To ensure submerged depth, under this depth So that inner magnetic cavity is not intake, while high-grade encapsulation process is had also been made with sealing sheath to control feed cable.Turn magnetic cavity outside Prevent silt from entering in the gap between external magnet inner surface and inner magnetic cavity cylinder outer surface equipped with sealing ring on internal diameter, interior magnetic disk It is fixed with interior magnetic disk set, baffle ring and axis screw, is coupled with reductor shaft using key block.Inboard bearing and outboard shafts Hold use inside spider, inner shaft spider, baffle ring and axis screw fix, bearing sleeve flange face and end cap flange face it Between be coated with fluid sealant.
What technical solution provided by the invention was realized has the technical effect that such:Make motor band by controlling feed cable Speed reducer rotation, rotating speed and rotation direction are controllable.When motor rotates, reductor shaft will drive 8 by interior magnetic disk ~24 pieces of internal magnet rotations, since the poles S of 8~24 blocks of internal magnets and the poles N of 8~24 blocks of external magnets correspond, while interior magnetic Chamber cylinder is made of non-magnetic separator, and according to the attracting principle of magnet opposite pole, 8~24 blocks of external magnets will be with 8~24 Block internal magnet is rotated and is rotated, and 8~24 blocks of external magnets will drive the outer outer magnetic cavity wheel turned on magnetic cavity and outer shaft-cup to rotate together. 6~8 sealing outer bearings and inboard bearing and outboard bearing ensure that the outer concentricity for turning magnetic cavity internal diameter and inner magnetic cavity cylinder outer diameter. Due to 8~24 pieces of external magnet inner surfaces and inner magnetic cavity cylinder outer surface, 8~24 pieces of internal magnet outer surfaces and inner magnetic cavity tube inner surface Gap value is both designed as 0.5~1.0mm, and inner magnetic cavity barrel thickness is 3~5mm, and inside and outside magnet is all made of Nd-Fe-B permanent magnet system At, therefore transmission torque is very big.If the selection present apparatus is hoofing part, so that it may fix rubber on outer magnetic cavity wheel Wheel, is fixed on by several fixing threaded holes on mounting flange platform below walking arrangement;Such as select the present apparatus for it is underwater its The driving unit of its mode, so that it may synchronizing wheel, sprocket wheel and other connectors are loaded onto on coupling spindle.
The present invention provides a perfect technical solution for underwater operation equipment, and the technical program is novel, structure design Ingenious, reasonable, underwater sealing performance is good, and transmission torque is big, has novelty, creativeness and practicability, will be widely used in water The fields such as lower equipment.
