Description
Technical field
The utility model is related to motor field, specifically a kind of double self-lubricating bearing motors.
Background technology
Lubricating fluid is lubrication medium when mandrel corresponding shaft bearing rotates, and to reduce frictional dissipation therebetween, lubricating oil is with rotation
The friction that turns and can gradually be destroyed loss, and this be lost will be with the raising of temperature into geometry multiple increase.Therefore
It reduces relative friction and reduces rotation temperature and rise the service life that can be obviously improved self-lubricating bearing motor.
Common self-lubricating bearing structure fan electromotor, longevity is in the oil content of self-lubricating bearing lubricating oil, because of processing
The limitation of technique and material, at present under the premise of keeping necessary intensity, self-lubricating bearing can accomplish oil content 20% or so, by
This limitation, in addition the design self-lubricating bearing of fan electromotor and rotary shaft and non-tight, lubricating oil there are problems that being lost in, volatilize,
Vibrations in fan electromotor rotor rotation process either have once in a while in angles shifts or movement lubricating oil mandrel and from
It is supplemented between lubricating bearing not in time, oil film breakdown can be caused or can not form normal oil film, caused between mandrel and bearing between meeting
The generation of gap being in direct contact without oil film, this is the major reason for causing bearing wear and mandrel surface injury, this can cause
Operating lubricant environment between the two is detached from design normal range (NR), generates abnormal sound, unstable wear, this is self-lubricating bearing longevity
Another major reason.
Utility model content
It is mentioned above in the background art to solve the purpose of this utility model is to provide a kind of double self-lubricating bearing motors
Problem.
To achieve the above object, the utility model provides the following technical solutions：
A kind of double self-lubricating bearing motors, including stator and rotor, the stator interior are arranged with central siphon, and rotor is equipped with core
Axis is inserted with the first self-lubricating bearing and the second self-lubricating bearing inside the central siphon, and the first self-lubricating bearing is fixed on central siphon after assembling
It is interior cannot free relative motion, the second self-lubricating bearing cunning be fitted into the endoporus of the first self-lubricating bearing, the endoporus of the second self-lubricating bearing
In be equipped with mandrel, mandrel is inserted through the endoporus of the second self-lubricating bearing, and mandrel can be in the endoporus of the second self-lubricating bearing when work
Rotation；Described to be equipped with metal magnetic gasket in the bottom of central siphon, the magnetic force of metal magnetic gasket is sucked mandrel and reduces its left and right pendulum
Place the annulus that is magnetic in the top of dynamic and upper and lower play, first self-lubricating bearing.
As further program of the utility model：It is tight fit between first self-lubricating bearing and central siphon.
As the utility model further scheme：The top of the mandrel passes through the second self-lubricating bearing directly and metal
Magnetic gasket travel point opposite contacts.
As the utility model further scheme：The outer diameter and central siphon internal diameter close-fitting of the magnetism annulus, magnetism circle
Ring center is provided with circular hole.
As the utility model further scheme：The bottom of the central siphon is equipped with metal magnetic gasket, and first moistens certainly
Place the annulus that is magnetic in the top of bearing.
Compared with prior art, the utility model has the beneficial effects that：The utility model is Promethean by mandrel and single
The relative rotary motion of self-lubricating bearing is decomposed into mandrel to the normal relative rotary motion of self-lubricating bearing and self-lubricating bearing to profit axis certainly
The superposition of the relative rotary motion for the slow and intermittence held, in the case where vibrations or rotor angle change, by mandrel and the
The relative rotary motion of two self-lubricating bearings is transmitted between the second self-lubricating bearing and the first self-lubricating bearing, to substantially reduce
The abrasion that mandrel is generated with the direct relative rotary motion of self-lubricating bearing, reduces the generation of heat, substantially increases electrical machinery life, into
One step in order to reduce the play up and down and double swerve of rotor, add metal magnetic gasket and magnetic annulus jointly to mandrel
Suction is generated, it is reduced and is swung left and right and upper and lower play, more efficient improvement moving situation significantly improves electrical machinery life.
