Abstract
The utility model discloses a wearable bearing base, comprising a flange wearable base molded by alloy steel and a wearable sleeve. The flange wearable base comprises a flange connecting plate and a bearing sleeve cylinder; the wearable sleeve is arranged in the sleeve cylinder forming a gap cooperation; bottom of the wearable sleeve is arranged with a key hole cooperated with a tail shaft. the utility model using the technical solution has following advantages: the wearable sleeve and wearable base of the utility model uses the alloy steel, which is made from special technique; under working situation, the driven tail shaft drives the wearable sleeve to rotate in the wearable base; when wearing material enters the wearable base, the wearable base arranges a groove and side nick in an proper gap and the bearing sleeve bottom of the wearable base, discharging the material and wore material of the wearable sleeve and wearable base out of the bearing to strengthen sealing performance.
Description
Technical field
The utility model relates to a kind of bearing support, particularly a kind of good seal performance, the anti-friction bearing seat of long service life.
Background technique
At present domestic at cement industry to development aspect large-scale, energy-saving and environmental protection, the benefit because the large-scale production line construction needs conveying capacity big, the lifting height height, reliable conveying equipment adapts to supporting with it.The supporting noria specification of present status in China is increasing, and corresponding lift environmental requirement is more and more higher.Because the lift tailing axle is in quick condition, is a kind of universal phenomenon so leak ash herein, incompatible contemporary situation.
At present, lift tailing axle place sealing means mainly contains three kinds:
1. use skeleton oil seal with using between packing seal, tailing axle and bearing support between skeleton oil seal, drop bar and casing between tailing axle and drop bar;
2. use skeleton oil seal with using between packing seal, tailing axle and bearing support between packing seal, drop bar and casing between tailing axle and drop bar;
3. tailing axle and bearing support labyrinth sealing+grease chamber sealing+skeleton oil seal+cover plate for sealing.
Below the pluses and minuses of above-mentioned three kinds of sealing means are done to introduce down:
1. first kind of sealing means
Advantage: relatively simple for structure, low cost of manufacture.
Shortcoming: the outside framework oil seal of using between tailing axle and drop bar is easy to wearing and tearing, replacing outside framework oil seal inconvenience, because relative floating seal effect is bad between drop bar and casing, it is serious in the sealing that influence bearing support therefore generally to leak ash, and the environmental treatment workload reaches greatly keeps in repair inconvenience.
2. second kind of sealing means
Advantage: relatively simple for structure, stuffing box packing is changed conveniently between tailing axle and drop bar, and manufacture cost is relatively low.
Shortcoming: because therefore relative float and the lift charging has the material of dashing phenomenon sealing effect bad between drop bar and casing generally leak ash until the sealing that influence bearing support, the environmental treatment workload reaches the maintenance inconvenience greatly.
3. the third sealing means
Advantage: since with sealing plate with cutting off inside and outside it, so sealing effect is obvious.
Shortcoming: the out-of-level unsteady requirement of structure more complicated, tailing axle is high, because bearing support moves in the material environment, and the heatproof of bearing support, wear-resistant seal and anti-oil ageing require high, need fixed grease-added and lubricant oil.
This shows that the bearing support of above-mentioned three kinds of sealing means all exists and wears no resistance, and causes poor sealing performance, the shortcoming that working life is short.
Summary of the invention
The utility model provides a kind of wear resistance good at above-mentioned the deficiencies in the prior art, good seal performance, bearing support.
The technical solution of the utility model is achieved in that
A kind of anti-friction bearing seat, include wear-resisting seat of flange and wear-resistant sleeve by the alloyed steel casting, the wear-resisting seat of described flange comprises that flange land and bearing sleeve, wear-resistant sleeve are arranged in the bearing sleeve and constitute Spielpassung, and the bottom of wear-resistant sleeve is provided with the keyhole that is connected with tailing axle.
As preferably, be provided with groove in the bottom of bearing sleeve, be provided with breach along its length in the outer side surface bottom of bearing sleeve.During equipment operation, driven tailing axle drives wear-resistant sleeve and rotates in wear-resisting seat, in the abrasiveness material enters wear-resisting seat, by appropriate gap and the groove of wear-resisting seat bearing sleeve bottom setting and the breach on the outer side surface of wear-resistant sleeve and wear-resisting seat, the wearer of material and wear-resistant sleeve and wear-resisting seat is discharged outside the anti-friction bearing seat.
As preferably, described breach extends to the top by the bottom of bearing sleeve always.Thus, the setting of this breach not only can clog-free discharge wearer and material, and can only need open and observe the breach of door by wear-resisting with regard to its abrasion condition of observable so that the anti-friction bearing seat is safeguarded very conveniently.
For making wearer and material to discharge smoothly, as preferably, described groove is a toroidal cavity.
As preferably, the external diameter of described toroidal cavity equals the internal diameter of bearing sleeve.
As preferably, described keyhole is " one " font.
Adopted the advantage that the utlity model has of technique scheme to be: wear-resistant sleeve of the present utility model, wear-resisting seat adopt Special Alloy Steel, form by special casting technique casting, all through special thermal treatment, have higher fatigue strength and high wear resistance, bonded wear-resistant cover and wear-resisting seat special structural design, thereby reach the effect of well resistance to wearing is arranged, prolonged working life at the abrasive wear state; During equipment operation, driven tailing axle drives wear-resistant sleeve and rotates in wear-resisting seat, in the abrasiveness material enters wear-resisting seat, appropriate gap and the groove of wear-resisting seat bearing sleeve bottom setting and the breach on the outer side surface by wear-resistant sleeve and wear-resisting seat, the wearer of material and wear-resistant sleeve and wear-resisting seat is discharged outside the anti-friction bearing seat, thereby strengthened sealability.

Embodiment
Embodiment of the present utility model is as follows:
Embodiment: the utility model is according to the cement industry development trend, designed a kind ofly can adapt to bulk material and lifting height≤70m, the quantity delivered≤1500m that promotes powdery, granular, temperature≤250 ℃
3The bearing support of/h, as Fig. 1～shown in Figure 5, include wear-resisting seat 1 of flange and wear-resistant sleeve 5 by alloyed steel casting and process special thermal treatment, the wear-resisting seat 1 of described flange comprises flange land 2 and bearing sleeve 3, place, four angles on flange land 2 is equipped with attachment hole 8, wear-resistant sleeve 2 is arranged in the bearing sleeve 3 and constitutes Spielpassung, and the bottom of wear-resistant sleeve 2 is provided with the keyhole 4 that is connected with tailing axle, and described keyhole 4 is " one " font.As shown in Figure 6, the end of tailing axle 9 is provided with the key 10 that is complementary with keyhole 4, and key 10 is the loose fit transmitting torque with keyhole 4, the wear-resistant sleeve 5 outer wear-resisting seats 1 of flange that appropriate gap is housed.
