Abstract

The utility model discloses an anti-vibration and loosening resistant ball bearing, which comprises an anti-vibration and loosening resistant ring 1, an outer ring 2, a dust-proof cover 3, an inner ring 4, a retainer 5 and a roll ball 6, and is characterized in that the outer surface 7 of the outer ring 2 is provided with a groove combined with the anti-vibration and loosening resistant ring 1; the anti-vibration and loosening resistant ring 1 made of a polymer material is wrapped on the outer surface of the outer ring 2 in an injection molding way to be integrated. The anti-vibration and loosening resistant ball bearing has the advantages that the anti-vibration and loosening resistant ring 1 is wrapped on the outer cylindrical surface of the outer ring of the bearing and improves assembling accuracy when taken as an individual part, and simplifies a traditional process that the traditional bearing and an anti-vibration and loosening resistant ring are independently assembled.

Description

The locking ball bearing of a kind of anti-vibration

Technical field

The utility model relates to the bearing manufacture technology field, especially a kind of ball bearing with the anti-vibration anti-loose structure.

Background technique

Simple in structure, the wide application of ball bearing, be widely used in daily life and mechanical manufacturing field, but the occasion of jolting in vibration, often have the loosening phenomenon in outer ring of ball bearing, as a result bearing outer ring and the bearing chamber friction that occurs skidding makes the interior grease loss of bearing groove, time one is long, the aggravation of the groove frictional heating of steel ball and bearing ring makes the retainer heating, feels like jelly until damage, and particularly the mechanical component made by aluminium of bearing chamber is particularly serious.

At present, in mechanical manufacturing field, having adopts various measures avoids or reduces the measure of bear vibration, as in automobile industry, what use in the automobile current generator generally also is ball bearing, for fear of causing the loosening of bearing outer ring because of the automobilism vibration, when design of electrical motor, between the bearing chamber of anti-drive end and bearing outer ring, increased a plastic bushing, they adopt interference fit each other, the bearing outer ring of having avoided causing because of vibration becomes flexible the phenomenon of skidding, but the quality of fit when making Assembly of the parts because of many parts when its shortcoming is to use reduces, make production assembly process complicated, improved the administration cost of cost of production and storekeeper, therefore the improvement that awaits of traditional ball bearing structure.

Summary of the invention

Technical problem to be solved in the utility model is that a kind of a kind of ball bearing that designs ingenious, features simple structure, anti-vibration anti-loose structure is provided for above-mentioned prior art present situation.

The utility model solves the problems of the technologies described above the technological scheme that adopts: this ball bearing, comprise anti-vibration lock ring, outer ring, dust cover, inner ring, retainer and ball, described ball embeds and rollably places between outer ring and the inner ring in retainer, it is characterized in that: the outer surface of described outer ring is provided with the groove that combines with the anti-vibration lock ring, the anti-vibration lock ring made from macromolecular material is wrapped in the outer surface of outer ring by the form of injection moulding mold pressing, is made into integrative-structure.

As improvement, the two ends of the outer peripheral surface of described bearing outer ring are circular groove structure.

As improvement, the outer peripheral surface of described bearing outer ring also comprises spiral groove structured.

As improvement, the material of described anti-vibration lock ring is Teflon.

As improvement, the material of described anti-vibration lock ring also can be nylon or other plastics.

As improvement, described anti-vibration lock ring and outer ring are made into one.

As improvement, described anti-vibration lock ring and outer ring all-in-one-piece preparation process and method are that the surface applies.

As improvement, described anti-vibration lock ring and outer ring all-in-one-piece preparation process and method also can adopt mold pressing.

As improvement, described anti-vibration lock ring and outer ring all-in-one-piece preparation process and method also can adopt injection moulding.

As improvement, the thickness of described anti-vibration lock ring needs by design and decides.

Above-mentioned Teflon, namely teflon has the characteristics of antiacid alkali resistant, anti-various organic solvents, is dissolved in hardly all solvents.Simultaneously, high temperature resistant, highdensity characteristics that teflon has are applicable to the demanding occasions such as high temperature; Nylon is suitable for the occasion of general temperature, and other general plastics can be selected as required.The external peripheral surface of above-mentioned outer ring can certainly be smooth circumferential surface, also can be axial straight burr concave, convex face.

Compared with prior art, the utility model has the advantage of simple in structure, the assembling simple and convenient, plastic materials because of the bearing outer ring bag again, has the extruding contractibility, large with the magnitude of interference that cooperates of bearing chamber, quality of fit also can suitably reduce, more bigger magnitude of interference can not make race deformation cause the life-span that the bearing air gap reduces to affect bearing when can be as conventional bearing bearing being pressed into bearing chamber because of the extruding between the metal, also the elastic reaction because of plastics plays the locking effect of anti-vibration to mechanical assembly, thus the working life of having improved bearing.

Embodiment

Below in conjunction with embodiment the utility model is described in further detail.

Fig. 1 is to the locking ball bearing of anti-vibration of present embodiment shown in Figure 3, include anti-vibration lock ring 1, outer ring 2, dust cover 3, inner ring 4, retainer 5 and ball 6, described dust cover 3, inner ring 4, retainer 5 and ball 6 all with NBS in the structure of ball bearing part of the same name, shape is identical, the outer surface 7 of outer ring 2 is provided with the groove that combines with anti-vibration lock ring 1, anti-vibration lock ring 1 is wrapped in the outer surface of outer ring 2 by the form of mold pressing injection moulding, then is machined to the desired precision of bearing.

During installation, whole bearing is compressed into axle by the inner ring cover, the outer ring is pressed into bearing chamber together with axle and whole bearing and gets final product.
