Model utility content
The purpose of this utility model is intended to the defect that load-carrying ability is not good enough, volume is larger of the double-row conical bearing overcome in existing automobile hub bearing, there is provided a kind of and can bear larger axis and united load, compact structure and the little integration automobile hub bearing of volume.
For this reason, the utility model is by the following technical solutions: integration automobile hub bearing, comprise bearing inner race and bearing outer ring, double-row conical is fixed with by retainer between bearing inner race and bearing outer ring, it is characterized in that, described automobile hub bearing also comprises seat ring and sealing mechanism, the inner hole wall of seat ring is arranged the interior concave spherical surface of ring-type, the periphery of described bearing outer ring is provided with the outer convex spherical of the ring-type corresponding with described interior concave spherical surface, seat ring is set in described bearing outer ring, make described interior concave spherical surface and evagination mating spherical surfaces, described bearing outer ring and described seat ring time is made to form plain radial bearing structure, improve axial and radial load-carrying ability, described sealing mechanism is provided with two and is arranged at the two ends of described bearing outer ring respectively, each sealing mechanism comprises seal ring, skeleton and spring, the periphery of skeleton is fixed on the inner headed face of described bearing outer ring, seal ring is fixed on described skeleton, seal ring is provided with a primary seal lip and a dust excluder lips, primary seal lip and dust excluder lips are all resisted against on the periphery of described bearing inner race, described primary seal lip is provided with annular spring groove, described spring is flush-mounted in this annular spring groove, make sealing lip tight abutment in the periphery of described bearing inner race by the tension force of spring, realize the Exposure of automatic compensation sealing, ensure good sealability.
As to technique scheme supplement and perfect, the utility model also comprises following technical characteristics.
Described seat ring internal diameter two ends are respectively arranged with towards the circular cone inclined-plane at two ends, make seat ring two ends form opening towards the horn mouth at two ends, facilitate the installation of seat ring and described bearing outer ring.
Described bearing inner race is made up of the little inner ring that two are set up in parallel vertically, and the periphery of two little inner ring opposite ends is fixed by a snap ring, and the two ends making two little inner rings relative closely cooperate.
The two ends that two little inner rings of described bearing inner race are relative are provided with an oil inlet hole, easy to use or stuffing in keeping in repair, and ensure that bearing lubrication is unimpeded.
Use the utility model can reach following beneficial effect: by plain radial bearing and double-row conical bearing are integrated in an automobile hub bearing, substantially increase axial and radial connected load, can self-aligning, compact structure, volume are little, function is many, Products integration of having withdrawn deposit, the light-weighted market demand; The Exposure of the tension force automatic compensation sealing of stainless steel spring by the sealing of S type lips double-contact, and is passed through in bearing two ends, ensures good sealability, effectively prevents internal grease excessive, improve the reliability of bearing, extend the working life of bearing.
