Abstract
The utility model discloses an asymmetrical automobile hub bearing unit which comprises a mandrel, a sensor, an outer ring, an inner ring, a tooth ring, an inner-row steel ball and an outer-row steel ball, wherein the inner-row steel ball and the outer-row steel ball are formed by the steel balls and retainers; the central diameter of the steel ball of the outer-row steel ball is larger than the central diameter of the steel ball of the inner-row steel ball; the retainer of the outer-row steel ball is larger than the retainer of the inner-row steel ball correspondingly; and the retainer of the outer-row steel ball and the retainer of the inner-row steel ball can match steel balls with different quantities. Due to the asymmetrical design of an inner-row bearing and an outer-row ring, the service life of the asymmetrical automobile hub bearing unit is effectively prolonged.
Description
Technical field
The utility model relates to the transmission part on a kind of automobile, particularly a kind of asymmetrical automobile hub bearing.
Background technique
At present, automobile hub bearing is generally double preset play angular contact ball bearing or tapered roller bearing.Two row's bearings are symplex structure, have identical load rating.But when automobile running, the actual load that effluxes bearing can be obviously greater than interior row's bearing, and therefore row's bearing determined the principal element of bearing life just to be to efflux the bearing load ability in its life-span also was shorter than usually.
Summary of the invention
The utility model technical problem to be solved provides a kind of asymmetrical automobile hub bearing, and inside and outside two row's bearing asymmetric design can effectively increase the service life.
The utility model technological scheme that adopts of dealing with problems is: a kind of asymmetrical automobile hub bearing; Comprise that mandrel, sensor, outer ring, inner ring, gear ring reach interior row's steel ball of being made up of steel ball and retainer and efflux steel ball; The said steel ball central diameter that effluxes the steel ball central diameter of steel ball greater than interior row's steel ball; The said retainer that effluxes steel ball is correspondingly also greater than the retainer of interior row's steel ball, and the steel ball of coupling varying number.
The beneficial effect of the utility model is: rational design has been carried out in the distribution to inside and outside two row's bearings; Increase and efflux the distance between the bearing, increase retainer, the steel ball of carrying greater number; Improve the load-carrying ability that effluxes bearing, effectively prolonged hub-bearing unit working life.
Description of drawings
Fig. 1 is the utility model embodiment's a sectional structure schematic representation.
Below in conjunction with accompanying drawing the utility model is further specified.
Embodiment
Shown in accompanying drawing 1; A kind of asymmetrical automobile hub bearing; Comprise that mandrel 1, sensor 4, outer ring 5, inner ring 8, gear ring 9 reach interior row's steel ball 11 of being made up of steel ball and retainer and efflux steel ball 12; Efflux the steel ball central diameter of the steel ball central diameter of steel ball 12 greater than interior row's steel ball 11, the said retainer 3 that effluxes steel ball 12 is also greater than the retainer 10 of interior row's steel ball 11, and 23 diameters of installation are 11.906 steel ball in the retainer that effluxes steel ball 12 3; Its dynamic load rating is 44.53 KN, and rated static load is 43.15 KN; 21 diameters of installation are 11.906 steel ball in the retainer 10 of interior row's steel ball 11, and its dynamic load rating is 42.62 KN, and rated static load is 38.87 KN.Sealing A 2, Sealing B 6 make whole working position form a sealing system with back-pressure lid 7, not influenced by dust, prevent the grease outflow.
During assembling,, clean each parts to processing of demagnetizing such as mandrel 1, outer ring 5 and inner rings 8; 21 steel balls of 23 steel balls that efflux steel ball 12 and interior row's steel ball 11 are respectively charged among retainer 3 and the retainer 10, the retainer that installs steel ball is packed among the outer ring 5, gear ring 9 is installed again; Indentation sealing spare A 2, Sealing B 6, inner ring 8; Build back-pressure lid 7, last mould pressing, installation wheel speed sensors 4, the assembly process of completion product.
