Abstract
The utility model relates to a ball bearing, concave and protruding an inner ring, an outer ring, steel balls and a crown type retainer 4 whose ball hole is provided with openings 6. The utility model is characterized in that an open slot 8 is arranged on a tooth between the openings 6 of the crown type retainer; the openings 6 are caused to have enough elastic expansion to meet that the retainer and steel balls are connected into a whole body, and the steel balls are not scratched; an assembly method that a mould expands the openings 6 of the retainer firstly and shrinks the openings 6 of the retainer to cause the steel balls and the retainer to be connected into a whole body is used to fully meet the large steel ball locking quantity of the openings 6. The utility model has the advantages of easy fabrication, convenient assemblage, flexible operation, reliable performance, etc.
Description
The utility model relates to a kind of bearing, particularly a kind of ball bearing.
Existing ball bearing, it is metal crown type retainer every what the ball device had, its ball breast has the opening of distance L less than sphere diameter d, makes the opening in ball hole that enough lock ball amounts be arranged.During assembling retainer ball hole is inserted on the steel ball by opening, utilizes its hold depth and steel ball to be connected as a single entity.Its deficiency is that its elastic deformation amount does not satisfy the requirement of hold depth, and steel ball is scratched, and causes deadly defects such as bearing operation is ineffective, noise is big, working life is low when passing through steel ball owing to opening.Thereby it seldom uses in ball bearing.
The purpose of this utility model is exactly for avoiding deficiency in the above-mentioned technology, and provides a kind of crown type retainer to avoid scratching the ball bearing of steel ball.
Technical solution of the present utility model is: a kind of ball bearing, it comprises that there is the crown type retainer of opening in inner ring or axle, outer ring or automotive hub flange plate, steel ball and ball hole, and it is characterized in that: the tooth upper edge is axially arranged with opening slot between the opening of described retainer ball hole opening end.Make ball hole opening that enough passing through steel ball and lock required hypertonic amount thereon be arranged.It is one of any that the shape of described crown type retainer can be tubular, cup-shaped, flute profile, Jiong shape, U-shaped.Its most suitable metallic stamping pieces.
The utility model is owing to be provided with opening slot at its retainer ball hole opening end, it compared with prior art, the existing enough hypertonic amounts of its opening satisfy it and are inserted on the steel ball and lock avoids scratching steel ball thereon, make it keep making simple, easy to assembly again and ball contacts good advantage with the ball hole.
The drawing of accompanying drawing is described as follows:
Fig. 1 is a kind of ball bearing structure signal of the utility model part sectioned view;
Fig. 2 is the retainer structural representation sectional drawing of a kind of ball bearing of the utility model;
Fig. 3,4 is respectively the structural representation sectional drawing of a kind of ball bearing of the utility model.
Below in conjunction with accompanying drawing the utility model technical solution is further described:
A kind of ball bearing structure signal of the present utility model as shown in Figures 1 and 2, it comprise inner ring 1, outer ring 2, steel ball 3 and ball hole 5 for cylinder, aperture D has the crown type retainer 4 of opening 6 distance L less than sphere diameter d greater than sphere diameter d's, it is characterized in that: tooth 7 upper edges are axially arranged with opening slot 8 between the opening 6 of described retainer 4 ball hole opening ends.Its depth H is greater than the distance X of center, ball hole to opening end, i.e. H＞X.Make opening 6 have contractility, utilize its opening property, opening 6 is opened and be inserted on the steel ball 3 that combines with inner ring 1, outer ring 2, when external force is eliminated, opening 6 is retracted to distance L less than sphere diameter d, i.e. L＜d, and retainer just lock be connected as a single entity thereon.When opening 6 had enough amounts of opening can satisfy its lock ball amount, steel ball can not scratch.When the lock ball amount of ball hole opening 6 bigger, when the amount of opening of opening can not satisfy it and requires, can utilize the characteristic of tooth 7 upper shed grooves 8, reach with assembly method and both can prevent to scratch steel ball, can easily retainer and steel ball be connected as a single entity again, its assembly method is: earlier opening 6 distances in retainer ball hole are expanded to greater than sphere diameter d with mould, perhaps opening 6 is made as greater than sphere diameter d, be mounted to then and inner ring 1, on the steel ball 3 that outer ring 2 combines, make ball hole opening 6 be contracted to distance L the expansion of the 8 usefulness moulds of the opening slot on the tooth 7 at last less than ball warp d, i.e. L＜d.Just reached and both can prevent that steel ball from scratching, and can easily and reliably be connected as a single entity it again.
Fig. 3 and Fig. 1 difference are to be provided with the rib 9 that constitutes radial seal with outer ring 2 internal diameters outside opening 6 the other ends of retainer ball hole on the warp, make it replace the effect of dust cover, seal ring.
One end face of Fig. 1,3 outer rings 2 is made as the wide end surface of internal diameter less than steel ball group switching centre footpath, just makes it become a kind of vehicle clutch disengaging bearing.
Fig. 4 and Fig. 1 difference are that outer ring 2 is two raceways, are furnished with the inner ring 1 of two band steel balls 3, retainer 4 on it, become a kind of automotive hub two-row ball bearing.Inner ring 1 is made as the axle of two raceways, just makes it become a kind of water pump connecting shaft two-row ball bearing.Inner ring 1 is made as one two raceways, and outer ring 2 is made as spherical raceway, just becomes a kind of biserial double row self aligning ball bearings.
A kind of ball bearing of the utility model owing to be provided with opening slot 8 on the tooth 7 between its retainer opening, makes opening 6 that enough elasticity hypertonic amounts be arranged, and is one and do not scratch steel ball to satisfy retainer and steel ball plug-in mounting; When itself and steel ball being connected as a single entity the retainer opening 6 first assembly methods of expanding aftershrinkage, more can satisfy opening 6 has bigger lock ball amount.It has makes advantages such as simple, easy to assembly, that ball contacts well with the ball breast, go slick, noise is low, use is reliable.
Claims (4)
1, a kind of ball bearing, it comprises that there is the crown type retainer (4) of opening (6) inner ring (1), outer ring (2), steel ball (3) and ball hole (5), is characterized in that: be provided with opening slot (8) on the tooth (7) between the described maintenance ball hole opening (6).
2, bearing as claimed in claim 1 is characterized in that: the opening slot (8) that described tooth (7) is provided with, its depth H is greater than the distance X of ball breast (5) center to opening end, i.e. H＞X.
