Abstract
The utility model relates to a bearing, in particular to a double-row conical roller bearing, which is used for a hub unit of an automobile. The double-row conical roller bearing comprises an inner plug which has a shaft hole; an inner ring is sleeved outside the inner plug; an outer ring is sleeved outside the inner ring; the outer ring and the inner ring form a retainer channel; a pair of retainers is arranged in the retainer channel; rollers are arranged in the retainers; and a break angle of the outer ring is a chamfer angle. The double-row conical roller bearing has a simple structure and an obvious using effect and is high in installation accuracy, and the service life is prolonged.
Description
Technical field
The utility model patent relates to a kind of bearing, relates in particular to a kind of double-row conical bearing, is used for automobile hub unit.
Background technique
The automobile hub unit middle (center) bearing of present existing technology, the structure relative complex, assembly precision is low, and trouble is installed, and using effect is not good.
Chinese patent CN200620108249.5 discloses a kind of automobile hub unit assembly, comprises mandrel, outer ring, inner ring, first rolling element and second rolling element; The outside of mandrel is furnished with raceway groove; The inboard of outer ring is furnished with the biserial raceway groove, and clamping has first rolling element between outer ring and the inner ring, and clamping has second rolling element between outer ring and the mandrel; Inner ring is fixed on the mandrel that passes from its inside; The external diameter interference fit of the internal diameter of inner ring and mandrel forms and is fixedly connected, and the spinning riveted construction is adopted in the end of mandrel, and the spinning riveted construction is close to the large end face of inner ring.This structure relative complex, and assembly precision is relatively low, and using effect is unoutstanding.
Summary of the invention
The utility model mainly is to solve the deficiency that exists in the existing technology, provides a kind of simple in structure, and the outstanding double-row conical bearing of using effect.
The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals:
A kind of double-row conical bearing; The interior plug that comprises the tape spool hole is with inner ring beyond the Great Wall in described, and described inner ring is with the outer ring outward; Described outer ring and inner ring form the retainer passage; Be provided with a pair of retainer in the described retainer passage, be provided with roller in the described retainer, the knuckle of described outer ring is a chamfering.
This structure relative compact, assembly precision is high simultaneously, improves whole service property (quality) and working life.
As preferably, the width of described outer ring is less than the width of inner ring, and the angle of described outer ring chamfering is 15 degree.
As preferably, inner ring and back inner ring before described inner ring comprises, described before inner ring with after the amalgamation of inner ring phase be connected.
Therefore, a kind of double-row conical bearing of the utility model, simple in structure, installation precision is high, improves working life, and using effect is remarkable.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
