Abstract
The invention provides a method for manufacturing an insulating bearing housing of an electric motor bearing and the insulating bearing housing of the electric motor bearing. The method comprises the following steps of: packing a layer of insulating material on the inner housing of the insulating bearing housing of the electric motor bearing; sintering the insulating material on the inner housing of the insulating housing of the electric motor bearing in a heating way; forming a layer of even insulating layer on the inner housing of the insulating housing of the electric motor bearing; naturally cooling after forming the insulating layer by the means that the insulating material is sintered on the inner housing of the insulating housing of the electric motor bearing; after cooling to normal temperature, heating up the housing of the insulating housing of the electric motor bearing, so that the housing is expanded in a heating way and then is sleeved on the inner housing of the insulating housing of the electric motor bearing which is cooled and is provided with an insulating layer; and naturally cooling, so that the cooled housing of the insulating housing of the electric motor bearing can be tightly hoped on the insulating layer of the inner housing of the insulating housing of the electric motor bearing to form a complete insulating housing of the electric motor bearing.
Description
Technical field
The present invention relates to a kind of modular construction of motor, refer in particular to a kind of insulation mode and structural shape of motor bearings.Be mainly used in the bearing insulation that is applicable to various motors.
Background technology
Electronic rotor often is in a kind of state that runs up at work, in order to guarantee the normal operation of rotor, all bearing can be housed in the proper site of rotor, can guarantee effectively that like this rotor is under situation about running up, can turn round stably for a long time, and be unlikely to scaling loss.But present many motors require bearing to play in the rotor operation process and guarantee that rotor normally runs up, and also require bearing to have certain insulating properties, promptly require to insulate between bearing pedestal and the bearing.For head it off, all be to inlay an insulation bearing overcoat more generally now in the appearance of bearing, present insulation bearing overcoat generally all is directly to put an overcoat that includes insulating barrier on bearing, the formation of its insulating barrier is to form by an insulating barrier is set between the overcoat of insulation bearing overcoat and interior cover, and this layer insulating puts by manual directly insulating tape being wrapped in the bearing outside, be inserted in formed at overcoat with bearing outside, though formed like this insulation bearing overcoat is relatively simple for structure, but there is the thickness of insulating layer inequality, volume is big, insulation effect is not a problem such as fine, therefore necessary this is further improved.
Summary of the invention
Technical problem to be solved by this invention is the existing deficiency of insulation bearing overcoat at existing motor bearings, provide a kind of more insulation effect better, and volume is littler, cooperates the manufacture method and the bearing insulation overcoat thereof of better New-type electric machine bearing insulation overcoat.
In order to solve the problems of the technologies described above, the present invention proposes the technology implementation scheme: a kind of manufacture method of insulation bearing overcoat of motor bearings, in the motor bearings insulating coating, put earlier parcel one deck insulating material, adopt mode of heating that the insulating material sintering is put in the motor bearings insulating coating again, in the motor bearings insulating coating, put and form the layer of even insulating barrier, the material of insulating material is polyvinyl chloride or other insulating material, can be powder or film material, putting in the motor bearings insulating coating and forming thickness of insulating layer is the 0.5-1.5 millimeter, the mode of mode of heating is electric heating, can be inductance heating or electromagnetism heating; Natural cooling the insulating material sintering puts the formation insulating barrier in the motor bearings insulating coating after, after being cooled to normal temperature, in overcoat heating with the motor bearings insulating coating, make its expanded by heating, and after expansion, be inserted in and cooled off, have insulating barrier the motor bearings insulating coating in put natural cooling again, make after the overcoat cooling of motor bearings insulating coating can lock ring on the insulating barrier of the interior cover of motor bearings insulating coating, form a complete motor bearings insulating coating.
The motor bearings insulating coating produced according to above-mentioned manufacture method is: a kind of motor bearings insulating coating, comprise overcoat, interior cover and insulating barrier, and it is characterized in that described insulating barrier is that sintering puts interior, and the thickness of insulating barrier is the 0.5-1.5 millimeter; The insulating material of described insulating barrier is polyvinyl chloride or other material.
The invention has the advantages that.The present invention adopts sintering processing to form insulating barrier at the interior cover of motor bearings insulating coating, therefore general relatively manual winding of formed insulating barrier wants much even, therefore required thickness of insulating layer can dwindle greatly, therefore under the situation that guarantees same insulation property, it is very little that the radial dimension of motor bearings insulating coating can be done, the size that helps whole motor is like this dwindled, and simplifies the structure of motor greatly.
