Abstract
The utility model discloses a sealed reluctance motor, which comprises a stator, a rotor, a rotor shaft and a winding. A sealing barrel is arranged between the stator and the rotor, and two ends of the rotor shaft are supported on the sealing barrel through bearings. The sealing barrel is welded with the stator. The end surface of the stator is sealed through a sealing end cover. The sealed reluctance motor is simple in structure, reliable in sealing and capable of preventing harmful gas from leaking.
Description
Technical field
The utility model relates to the reactor engineering technical field, particularly a kind of sealed type reluctance motor.
Background technology
Impervious machine is existing bigger application in industry, the more open-air that is used for is full of under water smoke, dust fills the air all around the environment (as industries such as some metallurgy, coal, chemical industry, oil), these occasions are all selected the motor than high-protection level for use, to improve reliability, guarantee the normal operation of equipment.From its sealing principle; labyrinth sealing, V-type rubber axis seal ring and the skeleton rubber seal of employing etc. arranged; though these seal form have had very big effect in industry; but the purpose of existing hermetically-sealed construction form is in order to protect motor; prevent the external environment condition medium to the machine operation Effect on Performance, and can not satisfy the sealing of pernicious gases such as radgas, toxic gas.
Owing to have very high radioactivity in the reactor inside, and existing impervious machine can't satisfy the needs of reactor.In the open source literature relevant report is not arranged at home and abroad at present.
Summary of the invention
The utility model has overcome deficiency of the prior art, provide a kind of simple in structure, sealing reliable, can prevent the sealed type reluctance motor that pernicious gas leaks.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
A kind of sealed type reluctance motor comprises stator, rotor, armature spindle, winding, and key is, be provided with sealing drum between stator and the rotor, on sealing drum, sealing drum and stator weld by bearings at the two ends of armature spindle, and the end face of stator seals by end cover.
The utility model is all right:
The end face of described stator is provided with seal groove by the end face that end cover is sealed into stator, and seal groove is placed with sealing ring, is pressed on the stator by end cover to seal.Described rotor is connected by key with armature spindle.The upper end of described armature spindle on sealing drum, is provided with pad between bearing and the rotor by bearings.The lower end of described armature spindle on sealing drum, is provided with circlip between bearing and the sealing drum by bearings.
Compared with prior art, the beneficial effects of the utility model are:
This device is by being arranged on sealing drum between stator and the rotor, radioactivity, gas such as poisonous can be included in the sealing drum like this.And the static seal that adopts fully of motor, do not have movable sealing in the motor, so its sealing is reliable, can effectively make the motor interior or exterior space isolated, harmful working media is included in the space at motor internal place.Adopt O type circle static seal simultaneously at the two ends of motor, make the sealing of motor more reliable, can protect personnel's operational environment to greatest extent.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
The section of structure of a kind of sealed type reluctance motor as shown in Figure 1, its agent structure are mainly formed stator 9, rotor 6 and sealing drum 7 coaxial arrangement by stator 9, rotor 6, armature spindle 11, sealing drum 7, winding 8 etc.Winding 8 is arranged in the groove of stator 9.
The A-A structure cutaway view of motor as shown in Figure 2, sealing drum 7 is made up of two kinds of materials, is permeability magnetic material over against the part of stator 9 magnetic poles, and remainder is a non-magnet material.Rotor 6 and armature spindle 11 are fixedlyed connected by key, armature spindle 11 by two bearing 4,10 together support up and down on sealing drum 7, the upper end of armature spindle 11 is supported on the sealing drum 7 by bearing 4, between bearing 4 and the rotor 6 pad 5 is set, adjusts fit-up gap between bearing 4 and the rotor 6 by adjusting pad 5.The lower end of armature spindle 11 is supported on the sealing drum 7 by bearing 10, between bearing 10 and the sealing drum 7 circlip 12 is set, and circlip 12 is used for carrying out spacing to bearing 10.
Connect by seal weld between sealing drum 7 and the stator 9, can make sealing drum 7 become the inwall of stator 9.
The upper surface of stator 9 is provided with seal groove, places sealing ring 2 in the seal groove, by bolt 3 end cover 1 is pressed on the stator 9, can be with inside and outside space of motor upper end gas-insulated.
The bottom of motor can be connected with execution unit by armature spindle 11, after on stator 9 lower surfaces sealing ring being set, the container at motor and execution unit place can be coupled together by bolt, the space at motor cavity place can be completely cut off fully reliably with outside.Pass through to winding 8 galvanizations simultaneously, under the active force of magnetic circuit, armature spindle 11 is rotated under the driving of rotor 6, can drive execution unit and move.
