Abstract
The utility model discloses a seal structure's bearing unit, including outward flange, inner flange, half inner circle, rolling element, holder, gear circle, ABS sensor, O type circle, the disc is opened in the outward flange has two raceways, opened a raceway on the outer disc of half inner circle and inner flange separately, two raceways of outward flange are corresponding with the raceway of the raceway of half inner circle and inner flange respectively, gear circle plug bush is on the excircle of half inner circle, ABS sensor plug bush is and cooperate with the gear circle on the outward flange external diameter, it has O type groove to open on the external diameter of outward flange, O type circle inlays to be established at O type inslot, O type circle and the interior circle in close contact with of ABS sensor, the outside of pressure at O type sealing washer is closely adorned to the ABS sensor to play sealed dirt -proof effect, this type of seal structure easy operation, production efficiency be high, be convenient for keep site environment clean and tidy, and low in manufacturing cost.
Description
Technical field
The utility model relates to a kind of hub-bearing unit, specifically a kind of bearing unit of sealing configuration.
Background technique
The assembling mode of such hub-bearing unit abs sensor, is the inner side of the Steel Skeleton housing liquid sealed colloid being coated in abs sensor at present, is pressed on the external diameter of outward flange more afterwards by abs sensor dress; Thus play the effect of sealing and dustproof.But, this type of assembling mode inconvenient operation in implementation process; Have and there is colloid and be mixed into the risk affecting its using function inside hub-bearing unit, colloid easily causes waste when being coated with note and manufacturing efficiency is low simultaneously.
Model utility content
For deficiency of the prior art, need a kind of bearing unit sealing configuration not needing colloid to seal.
For realizing above-mentioned technological scheme, the utility model needs a kind of bearing unit of sealing configuration, comprise outward flange, inner flange, half inner ring, rolling element, retainer, gear ring, abs sensor, O type circle, described outward flange inner headed face has two raceways, the periphery of described half inner ring and inner flange has separately a raceway, two raceways of outward flange are corresponding with the raceway of half inner ring and the raceway of inner flange respectively, described rolling element to be arranged on retainer and to be arranged in two groups of described raceways, described gear ring sleeve is on the cylindrical of half inner ring, described abs sensor sleeve outside flange outer diameter matches with gear ring, the external diameter of described outward flange has O type groove, described O type circle is embedded in O type groove, O type circle and abs sensor inner circle close contact.
Described inner flange is provided with 5 boss bolts.
Described outward flange and inner flange joint are provided with three lip rubber seal.
Be provided with 17 rolling elements in described raceway, the diameter of rolling element is 11.1125.
The utility model has the advantages that: by arranging O type groove on the external diameter of outward flange, and at the O RunddichtringO of O type groove built with standard; Then abs sensor is closely filled the outside being pressed in O RunddichtringO, thus play the effect of sealing and dustproof; This type of sealing configuration is simple to operate, manufacturing efficiency is high, it is clean and tidy to be convenient to maintenance site environment, and low cost of manufacture.
