Description
Technical field
A kind of submersible motor is the utility model is related to, it includes casing, stator, rotor and sealing device.
Background technology
The structure of submersible motor generally comprises casing, stator, rotor and sealing device, is quiet between its casing and end cap
Sealing structure is connected, and because the main shaft of rotor will stretch out from end cap, movable sealing structure, i.e. main shaft are taken between rotor and end cap
Sealing ring is provided between end cap, sealing property can decline after sealing ring is worn, and water can enter stator winding, make stator around
Group insulating properties reduce, so as to which electric leakage or winding coil short circuit occur.It is therefore desirable to be improved.
The content of the invention
The technical problems to be solved in the utility model is to provide a kind of submersible motor, and the submersible motor can effectively prevent water
Into stator winding.
The utility model solve technical problem technical scheme be：A kind of submersible motor, it includes casing 1, is pressed into machine
Stator 2, slotting rotor 3 in the stator in shell, left end cap 4 are connected with casing, and right end cap 5 is to be integrally formed with casing, waterproof
Cable 11 sealingly extends through right end cap and the lead of stator winding connects, and the left end of the main shaft 7 of rotor stretches out from left end cap, main
The right-hand member of axle is inserted in right end cap not to be exposed from right end cap, and the both ends of main shaft pass through clutch shaft bearing 8 and second bearing respectively
（8’）Supporting, it is characterized in that, sealing shroud is provided with the air gap between stator and rotor, the left end of sealing shroud has backwards to circle
The flange of heart extension, the right-hand member of sealing shroud have the flange towards center of circle extension, and the flange of sealing shroud left end is compressed by left end cap
On casing, flange and the right end cap of sealing shroud right-hand member are tightly connected, and the wall thickness of the sleeve body portion of sealing shroud is less than the length of air gap
Degree.
The characteristics of the utility model is that right end cap is integrally formed with casing, and flange and the right end cap of sealing shroud right-hand member seal
Connection, the flange of sealing shroud left end are connected with casing sealing, and sealing shroud separates stator and water, effectively maintains stator winding
Insulating properties.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Accompanying drawing mark represents respectively：1- casings, 2- stators, 3- rotors, 4- left end caps, 5- right end caps, 6- sealing shrouds, 7- master
Axle, 8- bearings, 9- sealing rings, 10- water joints, 11- water-proof cables, 12- bearing chambers, 13- projections.
Embodiment
In conjunction with brief description of the drawings specific embodiment of the present utility model.
A kind of submersible motor, it includes casing 1, the stator being ordinatedly pressed into casing 2, slotting rotor 3 in the stator, left
End cap 4 is connected with casing, and right end cap 5 is to be integrally formed with casing.
Right end cap is provided with water joint, and the lead of stator winding passes through the water joint 10 that is sealingly disposed on right end cap
It is connected with water-proof cable 11；Water-proof cable also can be directly through right end cap, the contact portion epoxy of water-proof cable and right end cap
Resin seal.
Clutch shaft bearing room 12 is provided with left end cap, clutch shaft bearing 8, a left side for the main shaft 7 of rotor are provided with clutch shaft bearing room
End is stretched out from clutch shaft bearing；Second bearing room 12 ', the right-hand member closing of second bearing room, second bearing are provided with right end cap
Second bearing 8 ' is provided with room, the left end of main shaft 7 is inserted in second bearing.
Sealing shroud is provided with air gap between stator and rotor, the left end of sealing shroud has backwards to the convex of center of circle extension
Edge, the right-hand member of sealing shroud have the flange towards center of circle extension, and the flange of sealing shroud left end is existed by left end cap by bolt presses
On the left side of casing.
The flange of sealing shroud right-hand member is tightly connected by flange and bolt with right end cap, and described bolt can pass through nut
Tighten, fluid sealant is scribbled between bolts and nuts；To improve sealing property, a projection can be also extended outward on right end cap
13, bolt is spun in projection.
The wall thickness of the sleeve body portion of sealing shroud is less than the length of air gap, without friction between sealing shroud when rotor rotates.It is close
Big envelope closes stator, and when being intake in motor, the insulating properties of stator winding are unaffected.Because sealing shroud will not be ground
Damage, therefore reliably stator winding can be kept to dry.
The water inlet position of this submersible motor is clutch shaft bearing room, and the particulate matter in water can be formed to bearing to wear, and be anti-
Only bearing is worn, and sealing ring 9 is provided between the oral area and main shaft of clutch shaft bearing room, to stop that particulate matter material enters axle
In holding, the sealing property of motor is also improved in addition.
