Description
Technical field
The utility model is a kind of whizzer motor with mobile bearing cover.It is a kind of motor with movable axle bearing sleeve by high-speed electric expreess locomotive Direct driver centrifugal spraying disk, and it mainly comprises high-speed electric expreess locomotive, spray disk, material dispersing plate etc.The utility model belongs to drying equipment technical field.
Background technology
The many employings of rotary atomizer in the past drive the scheme of centrifugal spraying disk rotating shaft by driven by motor speed increasing mechanism.There is a kind of rotary atomizer by high-speed electric expreess locomotive Direct driver centrifugal spraying disk both at home and abroad closely about ten years.Improve the efficiency of rotary atomizer, alleviate the weight of rotary atomizer, spray effect significantly improves.But due to motor seal problem, often occur that material enters motor along centrifugal spraying disk rotating shaft and causes the situation that motor winding makes moist, cause motor shorted to earth.
In addition, because high-speed electric expreess locomotive is that high speed shaft erects placement.When making the larger rotary atomizer of spray amount, because power of motor strengthens, thus rotor is very heavy.And the weight of rotor is born by bearing completely.Excessive axial force can make the overheated and serious wear of high-speed bearing.Thus limit by the application of rotary atomizer on large-scale spray dryer of high-speed electric expreess locomotive Direct driver centrifugal spraying disk.
Summary of the invention
The utility model provides a kind of fine sealing effectiveness that has, and the high-speed bearing that can reduce rotary atomizer is overheated and wearing and tearing, by the motor with movable axle bearing sleeve of high-speed electric expreess locomotive Direct driver centrifugal spraying disk.
The technical solution of the utility model is: in motor, adopt sleeve to be isolated by stators and rotators, and the inner circle of stator is close to by this sleeve, and its two ends are connected with the end cap at motor two ends respectively, and motor stator line bag is in an airtight cavity.Like this, even if having material or moisture to enter in motor along rotating shaft, stator line bag also can not be made to make moist.This whizzer motor with mobile bearing cover, it mainly comprises high-speed electric expreess locomotive, spray disk, material dispersing plate etc., it is characterized in that: in motor, have one for isolating the sleeve of stators and rotators, the inner circle of stator is close to by this sleeve, the two ends of sleeve are connected with the end cap at motor two ends respectively, form a closed cavity by sleeve, the end cap at motor two ends, electric machine casing, the stator of motor is arranged in this cavity.In order to make the air gap between motor stator and rotor as far as possible little, the wall thickness of the sleeve of isolation stators and rotators should be made as far as possible thin, in order to the intensity increased, the part increase lining of the air gap between stators and rotators can be stretched out at sleeve, form the more rational sleeve of one, it is characterized in that: the sleeve for isolating stators and rotators in motor is made up of one and thorax in the stator thin walled cylinder body be close together and the lining be positioned at outside stator thorax.
In order to increase the sealing of the motor with movable axle bearing sleeve, the rotating shaft corresponding with protecgulum axis hole increasing a helicla flute, forming a contactless movable sealing, it is characterized in that: in the rotating shaft corresponding with front enclosing cover axis hole, have helicla flute.This helicla flute rotation direction is contrary with motor steering.When armature spindle rotates, this helicla flute movable sealing can stop liquid to enter motor.
Because the rotor of Large-power High-Speed motor is very heavy, if the weight of rotor is born by bearing completely, then excessive axial force can make the overheated and serious wear of high-speed bearing.The utility model is in order to solve the problem, adopt following technical scheme: utilize the principle of same-sex repulsion between permanent magnet, the rotating shaft of the non-shaft stretching end of rotor is equipped with rubidium Fe-B permanent magnet, and the other rubidium Fe-B permanent magnet assembly corresponded is fixed in motor cover.The repulsive force between permanent magnet is utilized to support a part of rotor weight, thus rotor is played to the effect of axial aiding support, high-speed bearing is made to carry rational axial load, it is characterized in that: rubidium Fe-B permanent magnet unit is housed in the rotating shaft of the non-shaft stretching end of rotor, another rubidium Fe-B permanent magnet unit is fixed in motor cover, two permanent magnet ends are relative, and leave certain interval.Above-mentioned rubidium Fe-B permanent magnet unit can be a rubidium Fe-B permanent magnet, also can be one group of rubidium Fe-B permanent magnet.The relative Magnetic Phase of two permanent magnet unit with.
Because the material separating disc position with the motor of movable axle bearing sleeve is in hothouse, environment temperature is higher.Material separating disc in the past generally adopts stainless steel material to manufacture, and material separating disc is overheated easily makes the dried material retrogradation of thermal sensitivity, blocking spray disk.Solution of the present utility model is that enclosing cover before the motor with movable axle bearing sleeve is designed to have the structure of annular groove, material separating disc is embedded in the annular groove of front enclosing cover, it is characterized in that: material separating disc is embedded in the annular groove of front enclosing cover, the material of material separating disc adopts polytetrafluoroethylene.So dried material can not be made to be heated retrogradation, blocking spray disk.
The major advantage of the technical solution of the utility model is: in motor, 1, adopt sleeve to be isolated by stators and rotators, and motor stator line bag is in an airtight cavity.Even if having material or moisture to enter in motor along rotating shaft, stator line bag also can not be made to make moist.2, increasing spiral groove seal at the position that armature spindle is corresponding with protecgulum axis hole can stop liquid to enter motor to a certain extent.3, utilize the repulsive force supporting rotor between permanent magnet, thus rotor is played to the effect of axial aiding support, effectively prevent because excessive axial force can make the situation of the overheated and serious wear of high-speed bearing.
