Abstract
The invention discloses a shielding motor. The shielding motor comprises a motor casing, a front end cover, a rear end cover, and a stator and a rotor which are arranged in the motor casing. A shielding sleeve is arranged between the stator and the rotor in the motor casing so as to form a stator chamber and a rotor chamber, the rear end cover is in sealing connection with a balance cover, the balance cover is internally provided with a balance chamber and is provided with a medium inlet communicating with the balance chamber, the balance chamber communicates with the stator chamber, and a balance diaphragm is arranged between the balance chamber and the rotor chamber. The shielding motor is simple in structure and easy to realize. The balance cover is additionally arranged, the balance chamber communicating with the stator chamber is arranged in the balance cover, and the balance diaphragm is arranged between the balance chamber and the rotor chamber, such that pressure between the stator chamber and the rotor chamber is balanced and offset when the motor works, the requirement for the strength of the balance sleeve under a high-voltage condition is reduced, the production manufacturing cost is decreased, and power transmission of a magnetic field is not affected.
Description
Technical field
The present invention relates to a kind of motor, relate in particular to a kind of shield electric machine.
Background technology
Shield electric machine is a kind of sealed electric-motor, and it has totally-enclosed, safe feature, due to its structureOn there is no movable sealing, therefore can accomplish completely, without leaking, to be applicable to carrying inflammable, explosive, poisonous, corrosionProperty, radioactivity and precious liquid. But the shield electric machine on existing market can only be under the condition of low middle pressureWork, if be applied under condition of high voltage, need to increase the thickness of housing, and housing is blocked up, is unfavorable forMagnetic field transferring power, and increased manufacturing cost.
Summary of the invention
The object of the invention is to for the problems referred to above, a kind of shield electric machine is provided, to solve existing shielding electricityMachine needs to increase housing thickness under condition of high voltage, affects magnetic field transferring power, increase manufacturing costProblem.
The object of the invention is to be achieved through the following technical solutions:
A kind of shield electric machine, comprise motor casing, drive end bearing bracket, rear end cap and be arranged at stator in motor casing,Rotor is provided with housing to form stator chamber, rotor between stator and rotor in described motor casingChamber, is sealedly connected with balance lid on described rear end cap, be provided with balance chamber, and open in described balance lidHave the medium inlet being connected with balance chamber, described balance chamber is connected same with stator chamber, and counter balance pocketBetween chamber and rotor chamber, be provided with balance diaphragm.
As preferred version of the present invention, between described drive end bearing bracket and motor casing, be provided with 2 sealing rings, instituteState and between rear end cap and motor casing, be provided with 2 sealing rings.
As preferred version of the present invention, described balance diaphragm is convoluted diaphragm.
As preferred version of the present invention, between described rear end cap and balance lid, be provided with 2 sealing rings.
Beneficial effect of the present invention is that described shield electric machine is simple in structure, is easy to realize, by setting up balanceLid also has the balance chamber being connected with stator chamber in balance lid, and balance chamber and rotor chamber itBetween balance diaphragm is set, thereby make motor in when work, the pressure balance phase of stator chamber and rotor chamberSupport, reduced the requirement to housing intensity under condition of high voltage, thereby reduced manufacturing cost, and notAffect magnetic field transferring power.

Detailed description of the invention
Further illustrate technical scheme of the present invention below in conjunction with accompanying drawing and by detailed description of the invention. CanUnderstand, embodiment described herein is only for explaining the present invention, but not limitation of the invention.
Please refer to shown in Fig. 1, Fig. 1 is the structural representation of a kind of shield electric machine of the present invention.
In the present embodiment, a kind of shield electric machine, comprises motor casing 1, drive end bearing bracket 2, rear end cap 3 and arrangesStator 4 in motor casing 1, rotor 5, be provided with 2 sealings between described drive end bearing bracket 2 and motor casing 1Circle, is provided with 2 sealing rings between described rear end cap 3 and motor casing 1, it is fixed in described motor casing 1, to be positioned atBetween son 4 and rotor 5, be provided with housing 6 to form stator chamber, rotor chamber, described rear end cap 3On be sealedly connected with balance lid 7, between described balance lid 7 and rear end cap 3, be provided with 2 sealing rings, balanceIn lid 7, be provided with balance chamber 8, and have the medium inlet 9 being connected with balance chamber 8, described balanceChamber 8 is connected same with stator chamber, and between balance chamber 8 and rotor chamber, is provided with balance diaphragm 10,Described balance diaphragm 10 is convoluted diaphragm.
When use, to balance chamber 8 interior injection oil, when the pressure of rotor chamber is greater than the pressure of stator chamberTime, pressure is out of shape balance diaphragm 10, and then the oil pressure of 8 li of balance chamber is entered in stator chamber, fromAnd make the pressure balance in inside and outside two closed areas of housing 6, and thus, thinner housing 6Meet the requirement of high pressure.
Above embodiment has just set forth general principle of the present invention and characteristic, and the present invention is not subject to above-described embodimentRestriction, without departing from the spirit and scope of the present invention, the present invention also has various variations and change, thisA little variations and change all fall in the claimed scope of the invention. The claimed scope of the present invention is by appendedClaims and equivalent thereof define.
