Problems solved by technology
However, the bearing sleeves used in motor products in my country have long been made of steel and do not have insulation properties. Therefore, it is impossible to solve the electric corrosion caused by the axial current generated by the motor during the operation of the bearings assembled in the end cover. The smooth working surface of the bearing is corroded and scarred and uneven, resulting in increased energy consumption, increased noise, and shortened service life of the motor

The invention relates to the technical field of bearing sleeves, in particular to an insulating bearing sleeve for a motor. The insulating bearing sleeve comprises an outer ring, wherein a butt jointgroove is formed in the inner ring surface of the outer ring, an insulating splicing ring is inserted into the butt joint groove, an edge groove is formed in the surface of the insulating splicing ring, a connecting screw is arranged in the edge groove, an embedding groove is formed in the inner ring surface of the insulating splicing ring, a metal compensation ring is arranged in the embedding groove, the metal compensation ring is located on the outside of an inside track clamping outer ring, and the inside track clamping outer ring is located on the outside of an inside track clamping innerring. The insulating bearing sleeve has the beneficial effects that the structure of a traditional bearing outer ring is optimized, namely, the butt joint groove is formed in the surface of the outerring, the insulating splicing ring with an insulating effect is installed in the butt joint groove through the connecting screw, the embedding groove is formed in the surface of the insulating splicing ring for installing the metal compensation ring, and the metal compensation ring is connected with a retainer and steel balls to improve the wear resistance of a bearing.
Description
technical field [0001] The invention relates to the technical field of bearing sleeves, in particular to an insulating bearing sleeve for a motor. Background technique [0002] The bearing sleeve is an important part of the motor product. Its design structure and manufacturing process level have a decisive impact on the technical grade, performance, operation reliability, service life, energy consumption, and noise of the motor product. However, the bearing sleeves used in motor products in my country have long been made of steel and do not have insulation properties. Therefore, it is impossible to solve the electric corrosion caused by the axial current generated by the motor during the operation of the bearings assembled in the end cover. The smooth working surface of the bearing is corroded and scarred and uneven, resulting in increased energy consumption, increased noise, and shortened service life of the motor. Contents of the invention [0003] The object of the pres...
