Abstract

The utility model discloses a integration bearing used in a chemical fiber machinery, which includes a bearing shell, an inner race, a ball, a support and a sealing ring, the bearing shell also acts as a bearing outer race, a radial raceway is arranged on the outer edge of the inner race and the inner hole of the bearing shell, balls is arranged on the circular passage formed between the two raceways, the support is arranged on the outside of the balls to keep the spaces between the balls, the sealing ring is arranged on the sealing groove of the bearing shell to protect the grease in the bearing, the inner edge of the sealing ring extends to the both sides of the outer edge of the inner race. The utility model is a combination of the common bearing outer race and the shell suit to the chemical fiber machinery, namely to integrates them into one, so as to avoid the fitting problem between the bearing and the shell during installation procedures, increase the working reliability of the bearing, overcome deficiencies of the prior art which is easy to cause the earlier wear and failure, and also make the bearing installation easier.

Description

Integrated bearing

One, technical field

What the utility model patent related to is a kind of bearing, a kind of specifically deep groove ball bearing or angular contact ball bearing that is applied on the chemical fiber machinery.

Two, background technique

Bearing on the existing chemical fiber machinery comprises two kinds of deep groove ball bearing and angular contact ball bearings, its structure as depicted in figs. 1 and 2, all comprise two part compositions of bearing outside (Fig. 1) and bearing body (Fig. 2), during use, bearing body is put in the bearing outside, the outer ring of bearing body and the endoporus of bearing outside generally adopt the unit shaft system transition fit, endoporus one side of bearing outside also is provided with step and is used for the bearing body location of portion and fixing within it, in order to adapt to the special requirement on the chemical fiber machinery, the axial length of bearing outside is bigger, also is provided with the radial groove of many dress O type circles in the outer rim of cover.

Such structural feature has satisfied actual demand generally, but still has following shortcoming: because the existence of machining error, the endoporus of bearing outside can not be accomplished most suitable with cooperating of bearing body outer ring.Cooperate too pine, bearing body and overcoat can produce relative movement at work, make that the work of axle is unreliable, and make overcoat produce premature wear; And if the tension that cooperates, frictional force strengthens during bearing body work, heating causes bearing early failue easily.

Three, summary of the invention

1. goal of the invention: in order to overcome the problems referred to above of prior art, the utility model provides a kind of bearing body and overcoat has been combined, and does not exist both to cooperate unsettled a kind of integrated bearing.

2; technological scheme: integrated bearing described in the utility model; comprise bearing body and bearing outside; described bearing body is installed in the bearing outside; bearing body comprises inner ring; ball; retainer and seal ring; ball is installed in the raceway that the inner ring outer rim is disposed radially; the retainer of annular is installed in the ball outside to guarantee each ball spacing each other; be used to protect the seal ring of lubricating grease in the bearing to be installed in the seal groove of bearing outside; its inner rim extends to the both sides of inner ring outer rim; it is characterized in that: the position at the corresponding ball of bearing outside endoporus is provided with radially raceway; seal ring is fixed on radially raceway both sides, the raceway that ball can be on inner ring and outside the annular pass that radially forms between the raceway that puts roll.

The technical program is with the outer ring of plain bearing and is that the overcoat that adaptation chemical fiber machinery needs use combines, be about to both and be fabricated to one, the endoporus of overcoat is provided with radially raceway and seal ring according to the needs of bearing outer ring in the relevant position, and the axial dimension of overcoat is still consistent with life size, and radially is provided with the radial groove that is used to adorn O type circle on its outer rim.

3, beneficial effect: the utility model is integral the outer ring and the Analysis of Nested Design of bearing, avoids occurring the matching problem of bearing body and cover, has improved the reliability of bearing working simultaneously, has overcome the problem that prior art is prone to premature wear and early failue; Original bearing body must be packed into earlier in the overcoat, is installed on the chemical fibre manufacturing mechanism afterwards again, and adopts the utility model that both are integrated, and makes the easier for installation of bearing.

Four, description of drawings

Fig. 1 is the structural representation of the bearing body of prior art;

Fig. 2 is the structural representation of the bearing outside of prior art;

Fig. 3 is a structural representation of the present utility model.

Five, embodiment

Integrated bearing as shown in Figure 3, comprise bearing outside 1, inner ring 2, ball 3, retainer 4 and seal ring 5, bearing outside 1 double as bearing outer ring, be provided with radially raceway 7 in the relevant position of bearing outside 1 endoporus, radially be provided with raceway 6 on the outer rim of inner ring 2, ball 3 be installed in raceway 6 and the annular pass that radially forms between the raceway 7 in, and can roll along this annular pass.Retainer 4 is installed in ball 3 outsides; rely on retainer 4 each distance between cells to guarantee that each ball rolls each other under certain spacing; the outer rim of seal ring 5 is fixed on radially raceway 7 both sides; inner edge then keeps certain interval with inner ring 2 outer rims; it mainly acts on is the lubricating grease that adds in the protection bearing, makes foreign material can not enter raceway.In order to be fit to the needs of chemical fiber machinery, radially also be provided with many radial grooves 8 that are used to adorn O type circle in the outer rim of bearing outside 1.

Claims

1; a kind of integrated bearing; comprise bearing body and bearing outside (1); described bearing body is installed in the bearing outside (1); bearing body comprises inner ring (2); ball (3); retainer (4) and seal ring (5); ball (3) is installed in the raceway (6) that inner ring (2) outer rim is disposed radially; the retainer (4) of annular is installed in ball (3) outside to guarantee each ball spacing each other; be used to protect the seal ring (5) of lubricating grease in the bearing to be installed in the seal groove of bearing outside (1); its inner rim extends to the both sides of inner ring (2) outer rim; it is characterized in that: the position at the corresponding ball of bearing outside (1) endoporus (3) is provided with radially raceway (7); seal ring (5) is fixed on radially raceway (7) both sides, the raceway (6) that ball (3) can be on inner ring and outside the annular pass that forms between the radially raceway (7) that puts roll.
