Abstract
The utility model discloses a structure capable of preventing rotation of a bearing outer ring in a wheel hub. The wheel hub is sleeved on the bearing outer ring, a hemispheric clamping groove is arranged on the outer surface where the bearing outer ring is contacted with the wheel hub, a steel ball is arranged in the hemispheric clamping groove, one half of the steel ball is arranged in the hemispheric clamping groove, and the other half of the steel ball protrudes from the hemispheric clamping groove to extrude the wheel hub. The steel ball which can prevent the bearing outer ring from rotating is additionally arranged on a common bearing outer ring, the protrusion portion of the steel ball is arranged on the wheel hub in a press fitting mode, the steel ball enables the wheel hub and the bearing outer ring to be formed integrally, and under the overloading condition of the bearing outer ring, the steel ball can prevent the bearing outer ring from rotating. Under the condition that a little cost is added, the structure can solve the problem of batch failure of a market, can prolong service life of a common wheel hub shaft and can reduce unit added cost of using the wheel hub shaft.
Description
Technical field
The utility model relates to the automotive axle field, specifically a kind of structure that prevents the hub inner bearing outer ring rotating.
Background technology
In Chinese market, because the heavy duty truck dead-weight capacity is larger, work condition environment is abominable at present, cause market hub bearing outer ring rotating phenomenon more and more, and maintenance cost is relatively high.Although many heavy cards progressively replace plain bearing with hub-bearing unit, can prevent effectively that hub inner bearing from walking the outer ring, but the hub-bearing unit cost is higher, and the follow-up maintenance difficulty, for the moment can't replace in enormous quantities plain bearing to use in market, especially heavily block market.
The utility model content
The technical problems to be solved in the utility model provides a kind of structure that prevents the hub inner bearing outer ring rotating, can prevent effectively that the outer ring of hub inner bearing from rotating under heavily loaded pressure.
The technical solution of the utility model is:
A kind of structure that prevents the hub inner bearing outer ring rotating, be set with wheel hub on the described outside race, be provided with the semisphere draw-in groove on described outside race and the outside face that wheel hub contacts, be provided with steel ball in the described semicircle draw-in groove, half of steel ball is arranged in the semisphere draw-in groove, and second half is from the projecting inward extruding wheel hub of semisphere draw-in groove.
Be provided with the semisphere draw-in groove on described outside race and the annular end face that wheel hub contacts.
Described semisphere draw-in groove is two, and the circle center line connecting of two semisphere draw-in grooves is crossed the center of circle of bearing.
Advantage of the present utility model:
The utility model increases by one at common outside race and prevents the steel ball that outside race rotates, and the salient of steel ball is fitted on the wheel hub, and wheel hub and outside race are become one, and prevents that outside race from rotating under the case of heavy load being subjected to.The present invention can solve in batches fault of market increasing in a small amount of cost situation, can prolong common hub spindle service life, also can reduce the expense of using hub-bearing unit to increase.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
See Fig. 1, a kind of structure that prevents the hub inner bearing outer ring rotating, bearing is set with wheel hub 1 on 2 outer rings, be provided with two semisphere draw-in grooves on bearing 2 outer rings and the annular end face that wheel hub 1 contacts, the circle center line connecting of two semisphere draw-in grooves is crossed the center of circle of bearing 2, be provided with steel ball 3 in each semisphere draw-in groove, half of steel ball 3 is arranged in the semisphere draw-in groove, and second half is from the projecting inward extruding wheel hub 1 of semisphere draw-in groove.
Claims (3)
