Technical field
The present invention relates to bearing, be specifically related to a kind of Double-layer double-row four lip seal circle roller bearing.
Background technique
Bearing is in mechanical transmission course, play parts that are fixing and reduction load friction factor.Alternatively, when other parts produce relative movement each other on axle, be used for reducing the fixing parts of friction factor in power transmission process and retainer shaft central position.
Existing automobile bearing, wear resistance is not strong, reduces the working life of automobile.
Summary of the invention
The object of the invention is to the defect for prior art and deficiency, provide a kind of structure simple, a kind of Double-layer double-row four lip seal circle roller bearing reasonable in design, easy to use.
For achieving the above object, the technical solution used in the present invention is:
A kind of Double-layer double-row four lip seal circle roller bearing of the present invention, comprises bearing outer ring I, bearing inner race I, roller, seal ring, bearing outer ring II, bearing inner race II and supporting roller.The inner ring surface of described bearing outer ring I and described bearing outer ring II is provided with the groove holding described roller, the outer ring surface of described bearing inner race I and described bearing inner race II is provided with the groove holding described roller, described roller is located between described bearing outer ring I and described bearing inner race I, described seal ring is located between described bearing outer ring I and described bearing inner race I, described seal ring is located at described roller both sides, described roller is located between described bearing outer ring II and described bearing inner race II, described seal ring is located between described bearing outer ring II and described bearing inner race II, described seal ring is located at described roller both sides, annular groove is provided with outside described bearing inner race I, annular groove is provided with outside described bearing inner race II, described supporting roller is located in the groove of described bearing inner race I and described bearing inner race II,
Further, the internal diameter of described bearing inner race I 1mm larger than the internal diameter of described bearing inner race II;
Further, described bearing outer ring I, described bearing inner race I, described bearing outer ring II and described bearing inner race II adopt high molecular abrasion-proof material to make.
After adopting said structure, beneficial effect of the present invention is: the wear-resisting property effectively raising automobile bearing, extends the working life of automobile.
Accompanying drawing explanation
