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 housingof 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 being applicable to the bearing insulation of 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 effectively guarantee rotor in the situation that run up like this, 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, namely require to insulate between bearing pedestal and the bearing.For head it off, all be to inlay again an insulation bearing overcoat in the appearance of bearing generally now, present insulation bearing overcoat generally all is directly to put an overcoat that includes insulating barrier at bearing, the formation of its insulating barrier is to form by an insulating barrier is set between the jacket and inner sleeve of insulation bearing overcoat, and this layer insulating puts by manual directly insulating tape being wrapped in the bearing outside, be inserted in formed at the overcoat with bearing outside, though formed like this insulation bearing overcoat is relatively simple for structure, but exist thickness of insulating layer uneven, volume is large, insulation effect is not the 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 for existing motor bearings, provide a kind of more insulation effect better, and volume is less, cooperates 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 implementer's case: a kind of manufacture method of insulation bearing overcoat of motor bearings, in the motor bearings insulating coating, put first parcel one deck insulating material, adopt again mode of heating that the insulating material sintering is put in the motor bearings insulating coating, in the motor bearings insulating coating, put and form the uniform insulating barrier of one deck, 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 inductive heating or Electromagnetic Heating; Naturally cooling the insulating material sintering puts the formation insulating barrier in the motor bearings insulating coating after, after being cooled to normal temperature, in the overcoat heating with the motor bearings insulating coating, make its expanded by heating, and after expansion, be inserted in and cooled off, with putting again naturally cooling in the motor bearings insulating coating of insulating barrier, make after the overcoat cooling of motor bearings insulating coating can lock ring on the insulating barrier of the inner sleeve 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, inner sleeve 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 in the inner sleeve of motor bearings insulating coating, therefore relatively general manual winding of formed insulating barrier wants much even, therefore required thickness of insulating layer can dwindle greatly, therefore in the situation that guarantee same insulation property, it is very little that the radial dimension of motor bearings insulating coating can be done, the size that is conducive to so whole motor is dwindled, and greatly simplifies the structure of motor.
