Electrically insulated rolling bearings and rings electrically insulated rolling bearings

摘要

A group of utility models refers to those used in electric motors with regulated drive rolling bearings and components. Single technical result is to increase the reliability of the rolling bearing and is achieved by the fact that: - on the side, outer and / or inner surface of the ring rolling bearing or on a sublayer, which are previously coated with the above surface of the bearing ring, by thermal spraying in compliance with the ring temperature is not more than 150 ° C coated with the electrically insulating coating is a ceramic layer on the alumina-based compounds or impregnated with insulating varnish. - the rolling bearing comprising inner and outer rings placed therebetween rolling bodies, the outer and a side surface of the outer bearing ring and / or inner, and a side surface of the inner ring of the bearing or on the underlayer (auxiliary layer), which are previously coated with the above surface by thermal spraying, in compliance with the treated bearing race temperature of not more than 150 ° C coated with the electrically insulating coating is a ceramic layer on the alumina or e of compounds, the impregnated (soaked) with electrically insulating varnish.
