Description
Technical field
The utility model belongs to technical field of motor manufacture, and in particular to a kind of sealing device of motor the through position of the shaft.
Background technique
In the prior art at present, the sealing being related between A seating sliding bearing structure motor the through position of the shaft and axis,
Generally use sealing structure as depicted in figs. 1 and 2, including outsides cover of electric machinery 3, the first pressing plate 2, the second pressing plate 4, laminate 6 and hair
Felt 5.Outsides cover of electric machinery 3 and the first pressing plate 2 are bolted, and the first pressing plate 2 and the second pressing plate 4 are bolted, and laminate 6 is pressed
Tight felt 5 is fixed in the chamber that the first pressing plate 2 and the second pressing plate 4 are formed, and felt 5 is contacted with motor shaft 1.Motor passes through the first pressure
Plate 2, the second pressing plate 4 and laminate 6 compress felt 5, are sleeved on the through position of the shaft, and then will be between outsides cover of electric machinery 3 and motor shaft 1
Clearance seal get up.Existing sealing structural component is more, structure is complicated, installs or removes very inconvenient.Although in addition, the sealing
Structure can satisfy motor degree of protection and reach IP54 requirement, but as the implementation of GB3836.3-2010 standard is increased to electricity
The requirement of machine purging, axis perforation sealing structure not only need to meet the requirement of shelter of motor, and the air-tightness that also meet motor is wanted
It asks.Existing axis perforation sealing structure is to meet air-tightness requirement, often squeezes felt and axis close, leads to axis and felt friction
Fever, the temperature in turn resulting in axis increase, and heat transfer causes motor bearings temperature to increase, lead to motor shaft at pedestal
It is unqualified to hold temperature rise.
Summary of the invention
It is to meet air-tightness requirement axis and felt frictional heating is caused to transmit for prior art axis perforation sealing structure
To pedestal, the underproof problem of motor bearings temperature rise, the utility model aim is to provide a kind of motor the through position of the shaft
Sealing device.Sealing device structure provided by the utility model is simple, easy to use, and good heat dissipation overcomes existing axis perforation sealing
Structure holds the underproof problem of temperature rise, also ensures air-tightness requirement.
Technical solution adopted in the utility model is as follows:
A kind of sealing device of motor the through position of the shaft, including platen cover, copper sealing ring and outsides cover of electric machinery:
The platen cover is socketed on motor shaft, and there are gaps between platen cover and motor shaft；
The copper sealing ring is fixed on the inner circumferential surface of platen cover, between sealing clamp lid and motor shaft
Gap；
The platen cover is fixedly connected far from the end of motor shaft with outsides cover of electric machinery.
Further, the copper sealing ring is by inlaying the inner circumferential surface for being fixed on platen cover.
Further, there are four the copper sealing rings, the axially spaced-apart along motor shaft is arranged in parallel in platen cover
Circumferential surface.
Further, end of the platen cover far from motor shaft is bolted to connection with outsides cover of electric machinery.
Further, the bolt mounting holes on the platen cover amplify 2-3 mm, tune when being easily installed compared to the diameter of bolt
The concentricity of nodal axisn through position and motor shaft.
Further, the gap between the mating surface of end face and outsides cover of electric machinery of the platen cover far from motor shaft is 2-3
Mm adjusts the concentricity of the through position of the shaft and motor shaft when being easily installed.
A kind of sealing device of motor the through position of the shaft provided by the utility model, compared to existing sealing device,
The first pressing plate, the second pressing plate, laminate, the felt etc. on outsides cover of electric machinery are eliminated, original felt is changed to copper sealing ring, is dissipated
Heat is good.Not only simplify structure, solve caused by felt seal in the prior art squeezed between felt and axis it is close, felt with
Axis frictional heating leads to the underproof problem of motor bearings temperature rise, also meets the air-tightness requirement of motor.
