Background technology
Under water, application scenario such as explosion-proof, dustproof, need to adopt the motor of hermetically-sealed construction to drive.Motor seal structure commonly used at present is the mode that movable sealing and static seal combine, and wherein the motor output shaft place adopts the movable sealing mode, and other parts adopt O shape circle static seal mode, and movable sealing can be divided into sealing means such as O shape circle and rotating shaft lip again.Shown in the electric machine structure schematic diagram that Fig. 1 adopts the movable sealing of rotating shaft lip, adopt O shape to enclose 3 static seal modes between this electric motor end cap 1 and the casing 2, adopt O shape to enclose 3 static seal modes between coupling 4 and the casing 2, adopt rotating shaft lip 6 movable sealing modes between output shaft 8 and the casing 2, rotating shaft lip 6 compresses by rear end cap 7.Adopt this movable sealing structure can realize the effect that seals to a certain extent, have longer life-span and the rotating speed of Geng Gao than O type circle movable sealing mode, but the maximum deficiency of these two kinds of movable sealing modes is that movable sealing place exists mechanical friction, lower efficiency, produce noise on the one hand, cause the wearing and tearing of a lip on the other hand, reduce sealing life and reliability.
The utility model content
Technical problem of the present utility model is that a kind of do not have machinery friction, efficient height, noise is little, the life-span is long, sealing reliability the is high complete static seal compound machine of band magnetic gear will be provided.
In order to solve above technical problem, the utility model provides a kind of band magnetic gear complete static seal compound machine, comprises motor body, magnetic gear, seal closure, power transmission shaft; Described motor body comprises casing, end cap, stator, rotor, sealing ring; Described magnetic gear is made up of internal rotor, external rotor; Described power transmission shaft one end connects magnetic gear external rotor, and the other end connects driven shaft, adopts the complete static seal mode of seal closure between the motor body and the external world.Described magnetic gear internal rotor and machine shaft link together, described magnetic gear external rotor and described power transmission shaft link together, described seal closure is isolated the inside and outside rotor of magnetic gear fully, and seal closure is fixed on the casing, and seal closure and casing are realized static seal with O-ring seals.The transmission of torque of motor is undertaken by magnetic gear and power transmission shaft.
Described seal closure is made with non-conducting material or bad electric conducting material.
Described power transmission shaft adopts the supporting construction mode of duplex bearing, adopts sleeve to separate between the duplex bearing, is used to transmit the moment of motor.
When machine operation, machine shaft drives the rotation of magnetic gear internal rotor, and magnetic gear internal rotor magnetic field and external rotor magnetic field interaction drive the rotation of magnetic gear external rotor, and magnetic gear external rotor drives the power transmission shaft rotation, thus the torque of transmitting motor.
Superior effect of the present utility model is:
1) connect by the magnetic gear between machine shaft and the power transmission shaft, transmitting torque does not have Mechanical Contact between magnetic gear internal rotor and the external rotor, isolates fully by seal closure, adopts static seal between seal closure and the casing.Like this, adopt static seal between the motor body and the external world fully, do not have mechanical friction, can improve transmission efficiency and sealing life, reduce noise;
2) motor transmission shaft adopts the duplex bearing supporting construction, adopts sleeve to separate between the bearing, can transmit big moment and have strong anti-vibration, impact capacity.
