Background
The motor is an electromagnetic device which converts or transmits electric energy according to the law of electromagnetic induction, or converts one form of electric energy into another form of electric energy. The motor converts electric energy into mechanical energy.
At present, in the running process of the existing motor, electromagnetic noise is generated by the radial weight of a stator core due to the effect of an air gap magnetic field, and is transmitted to other parts through a magnetic yoke; secondly, the tangential weight of the air gap field, which opposes the electromagnetic torque, causes the core teeth portion to vibrate by deformation. When the radial electromagnetic wave is close to the natural frequency of the stator, resonance is raised, and vibration and noise are greatly enhanced.
The existing motor is high in noise in the operation process, noise pollution is easily caused, the corrosion resistance effect of the existing motor shell is poor, and the motor shell is easily rusted in the long-time use process.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a corrosion-resistant motor casing to solve current motor because the noise is great in the operation process, cause noise pollution's problem easily.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a corrosion-resistant motor casing, includes interior casing and inner cup body, the parcel has first sound insulation sheet layer on the interior casing, first sound insulation sheet layer surface mounting has the shell body, the parcel has second sound insulation sheet layer on the interior lid, install outer lid on the second sound insulation sheet layer, all install a plurality of semi-circular acoustic celotex boards on the inner wall of interior casing and interior lid.
Preferably, the shell and the outer cover body are both provided with corrosion-resistant layers.
Preferably, the semicircular acoustic panels are staggered on the inner walls of the inner casing and the inner cover.
Preferably, the inner cover body, the second sound insulation plate layer, the outer cover body and the corrosion-resistant layer are all provided with vent holes.
Preferably, the corrosion-resistant layer is made of a polytetrafluoroethylene material.
Preferably, the outer cover body is provided with a support lug, the support lug is provided with a mounting bolt, and the mounting bolt is connected with the outer shell through threads.
Compared with the prior art, the beneficial effects of the utility model are that: according to the corrosion-resistant motor shell, the electromagnetic noise can be reduced for two times through the first sound-insulation plate layer, the second sound-insulation plate layer and the semicircular sound-insulation plate, so that the noise pollution caused by the electromagnetic noise is avoided; through at outer casing and outer cover body surface covering corrosion resistant layer, can increase motor casing's corrosion resisting property, avoid appearing the condition of motor casing quilt corrosion.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 2-3, the present invention provides a technical solution: the utility model provides a corrosion-resistant motor casing, includes interior casing 1 and inner cup body 2, has first sound insulation sheet layer 3 through powerful gluing on the interior casing 1, and first sound insulation sheet layer 3 surface has shell body 4 through gluing, has second sound insulation sheet layer 5 through gluing on the interior lid 2, has outer lid 6 through gluing on the second sound insulation sheet layer 5, all has a plurality of semi-circular acoustic celotex boards 7 through the mounting screw on the inner wall of interior casing 1 and inner cup body 2.
Referring to fig. 1-2, the corrosion-resistant layer 8 is mounted on both the outer casing 4 and the outer casing 6 by screws, and the corrosion-resistant layer 8 is made of polytetrafluoroethylene, which has excellent chemical stability, corrosion resistance, sealing property, high lubrication non-adhesiveness, electrical insulation property and good aging resistance, so as to effectively improve the corrosion resistance of the motor casing.
Referring to fig. 2-3, the semicircular acoustic panels 7 are arranged on the inner walls of the inner casing 1 and the inner cover 2 in a staggered manner, when electromagnetic noise circulates along the air, since air flows across the semicircular acoustic panels 7 and air flows along the surfaces of the semicircular acoustic panels 7, and the noise is absorbed by the semicircular acoustic panels 7, the electromagnetic noise can be reduced layer by the semicircular acoustic panels 7.
Referring to fig. 2, the inner cover 2, the second sound insulation board layer 5, the outer cover 6 and the corrosion-resistant layer 8 are all provided with vent holes 9, and air circulation inside the motor housing can be ensured through the vent holes 9.
