Abstract
The invention discloses a special insulating bearing sleeve and a processing technology therefor. The special insulating bearing sleeve comprises an inner sleeve and an outer sleeve, wherein the outer sleeve is arranged outside the inner sleeve; an insulating filling layer is formed between the inner sleeve and the outer sleeve; the processing technology comprises the following steps: firstly, the bearing sleeve is parted into the inner sleeve and the outer sleeve separately; then the inner sleeve and the outer sleeve are cleaned; the connecting surface of the inner sleeve is painted with insulating paint and wound with a layer of non-woven fiber tape, and then the inner sleeve is put into a drying oven to be dried; the inner sleeve dried in the step S2 and the outer sleeve are combined and heated to a specific temperature, and the insulating filling layer is filled with an insulating layer filler through a pouring opening; and finally, the insulating bearing sleeve poured in the step S3 is put into the drying oven to be cured for two times, then the inner sleeve and the outer sleeve and an insulating material are combined into a whole body, and the temperature is reduced along with the drying oven to the room temperature after curing is performed, and next, a step of finish turning is performed. According to the insulating bearing sleeve, the inner sleeve and the outer sleeve are isolated through the insulating filling layer to block axial current so as to protect the bearing and prolong the service life of the bearing.
Description
Technical field
The invention belongs to bearing holder (housing, cover) equipment technical field, and in particular to extraordinary insulating bearing carrier ring.
Background technology
Bearing holder (housing, cover) is the strength member in motor product, and how are its design structure, manufacturing technology level, to motor product
Technical grade, performance, operational reliability, service life etc. have important impact.At present general bearing holder (housing, cover) is ironcasting and casting
Steel part, but because motor can produce shaft current in running, shaft current can produce corrosion by bearing to bearing, make bearing
Use the lost of life.
The content of the invention
It is an object of the invention to provide a kind of extraordinary insulating bearing carrier ring and its processing technology, to solve above-mentioned background technology
The problem of middle proposition.
For achieving the above object, the present invention provides following technical scheme：Extraordinary insulating bearing carrier ring, including inner sleeve and overcoat,
Overcoat is provided with the outside of the inner sleeve, between the inner sleeve and overcoat insulation fill stratum is formed.
Preferably, the thickness of the insulation fill stratum is 2-4mm.
Present invention also offers the processing technology of extraordinary insulating bearing carrier ring, comprises the following steps that：
S1, by bearing holder (housing, cover) parting, be divided into inner sleeve and overcoat, process technique seam in inner sleeve and outer set, and in insulation
Composition surface processes antiskid thread；
S2, cleaning inner-outer sleeve, inner sleeve composition surface brush insulated paint and wind one layer without latitude band, and be put into baking box 130
Dry at DEG C；
S3, by S2 dry after inner sleeve and overcoat merge, is formed gap for 2-4mm insulation fill stratum, then heat
To set point of temperature, while insulating barrier filler is heated up to consistent with the temperature of inner sleeve and overcoat, and stir, by cast
Mouth is poured into insulation fill stratum；
S4, the insulating bearing carrier ring after pouring into a mould in S3 is put into baking box and is heating and curing, solidify 3 in a low temperature of 80 DEG C first
Individual hour, then at a high temperature of 110 DEG C solidify 4 hours, make inner-outer sleeve and insulating materials be integrated, after the completion of solidification with
Baking box is together down to normal temperature, into smart car；
By process area when S5, smart car, technique seam all cars fall, and inner-outer sleeve is separated by insulating barrier completely.
Compared with prior art, the invention has the beneficial effects as follows：The extraordinary insulating bearing carrier ring, will be interior by insulation fill stratum
Set and overcoat separate, and play a part of to block shaft current, so as to protect bearing, extend the service life of bearing；The special type insulation
Bearing holder (housing, cover), has the advantages that reasonable in design, processes simple, convenient and practical, while the use longevity of bearing can be increased substantially
Life, can be used with popularity.
