Description
Technical field
The utility model relates to field of bearings, particularly relates to a kind of Novel double-row deep groove ball bearing.
Background technique
According to the difference of automobile model, on motor car engine idle pulley, what have selects biserial deep groove ball bearing as expansion tightening wheel bearing, the radial load that can bear for this bearing requires larger, generally about 1100N can be reached, therefore the design to this bearing, except will selecting high-quality raw material and technique, the sealing of bearing is very important, in prior art the outer ring of deep groove ball bearing inner wall end surface near be provided with seal groove, seal ring is embedded in described seal groove, but, the deep groove ball bearing of this structure, after seal ring embeds, sealing effect is poor, fat is leaked in as easy as rolling off a log generation, the working life of lubricating grease is difficult to meet the demands.
Model utility content
For the present situation of above-mentioned prior art, technical problem to be solved in the utility model is to provide a kind of scientific and reasonable for structure, good sealing effect, the Novel double-row deep groove ball bearing of long service life.
The utility model solves the problems of the technologies described above adopted technological scheme: a kind of Novel double-row deep groove ball bearing, comprise outer ring, inner ring, steel ball and retainer, described outer ring, the inside and outside surface of inner ring is equipped with double annular channel, steel ball is provided with in raceway groove, nylon cages is provided with in steel ball both sides, for enhanced leaktightness, external sealed groove and interior seal groove is had inside described outer ring with outside inner ring, this external sealed groove is notch arrangement, the step side of this interior seal groove is inclined-plane, is provided with seal ring between described external sealed groove and interior seal groove.
Further, described seal ring one end is three bead structures and the other end of sealing circle is provided with boss, and seal ring is fully contacted with inside and outside seal groove.
Further, described seal ring comprises skeleton, and this skeleton is wrapped in seal ring, increases crushing resistance and the working life of seal ring.
Compared with prior art, the utility model has the advantage of: the utility model compact structure compared with common biserial deep groove ball bearing, adopt the double density sealing groove of Internal and external cycle, and external sealed groove is notch arrangement, the step side of interior seal groove is inclined-plane, make the two ends of seal ring chimeric with inside and outside seal groove tightr, and crushing resistance is good, is beneficial to the working life extending sealing lip, prevents the leakage of lubricating grease, thus the working life of bearing can be extended, be applicable to large-scale promotion.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the partial enlarged drawing of the utility model seal groove.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based in the utility model being embodiment, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1-2, a kind of Novel double-row deep groove ball bearing, comprise outer ring 01, inner ring 02, steel ball 04 and retainer 46, external sealed groove 1 and interior seal groove 2 is had inside described outer ring 01 with outside inner ring 02, this external sealed groove 1 is notch arrangement, the step side of this interior seal groove 2 is inclined-plane, is provided with seal ring 68 between described external sealed groove 1 and interior seal groove 2.
Preferably, one end that corresponding sealing circle 68 is chimeric with external sealed groove 1 is provided with projection, seal ring 68 is three bead structures with one end of interior seal groove 2 tabling, there is the gap of 0.1 ~ 0.15mm in its first lip A and bearing internal external footpath, grease unnecessary in bearing can be stored in the groove of the first lip A, obstruction grease is excessive, second lip B and inner ring step contact of incline plane, light contact is kept to have 0.08 ~ 0.10 interference state, play seal action, 3rd lip C and interior seal groove bottom land have the gap of 0.1 ~ 0.15mm, prevent external dust from invading, owing to forming longer labyrinth seal passage, the sealing effect of bearing is made to reach optimum degree, skeleton 681 is provided with in sealing circle 68, skeleton 681 is wrapped in the effect playing support in seal ring 68, improve crushing resistance.
This Novel double-row deep groove ball bearing is in Vehicle Processing process, inside and outside seal groove and raceway groove adopt forming cutter cutting at one time to complete, therefore good concentricity, seal ring 68 contact surface roughness is reduced to below Ra0.63um, seal ring can be made to seal more reliable, particularly be conducive to the working life extending sealing lip, prevent the leakage of lubricating grease, thus the working life of bearing can be extended
Last it is noted that above embodiment is only in order to illustrate the technical solution of the utility model, be not intended to limit; Although be described in detail the utility model with reference to previous embodiment, it will be understood by those of skill in the art that it still can be modified to the technological scheme described in previous embodiment, or wherein portion of techniques feature has been replaced on an equal basis; And these amendments or replacement, do not make the essence of appropriate technical solution depart from spirit and the scope of each embodiment's technological scheme of the utility model.
