Abstract
The invention relates to a reinforced type tapered roller bearing which comprises two inner rings, an inner spacing ring, an outer ring, two retainers and rollers. The two inner rings are arranged in the outer ring side by side; the inner spacing ring is arranged between the two inner rings; the two retainers are arranged between the outer ring and the two inner rings; a two-raw rolling path is arranged on the inner wall of the outer ring; two rolling paths are arranged on the outer walls of the two inner rings respectively; the rollers are arranged in the retainers; the two retainers form components with corresponding inner rings respectively; the components are assembled in the two-row rolling path of the outer ring. Compared with the prior art, the reinforced type two-raw tapered bearing is adopted to replace a common tapered bearing, is quite suitable for the overloading requirement of a coal machine industry, and is applied to a swing planetary head of a coal mining machine, so as to allow the coal mining machine to make improvement and reach an advanced level both at home and abroad.
Description
Technical field
The present invention relates to bearing, particularly relate to a kind of enhanced-type tapered roller bearing.
Background technique
Coal winning machine is a large-scale complicated system that integrates mechanical, electric and hydraulic pressure, and work under bad environment, will cause the interruption of whole coal work if there is fault, cause huge economic loss.Along with the development of coal industry, the function of coal winning machine is more and more, the structure of himself, composition more sophisticated, thereby the reason breaking down is also thereupon complicated.Be the vitals of coal winning machine at coal machine profession middle (center) bearing, use under the operating mode of heavy load, conventionally adopt common conical bearing, load that this bearing bears is less, impact resistance is not strong, and therefore the life-span is shorter.
Summary of the invention
Object of the present invention is exactly to provide in order to overcome the defect that above-mentioned prior art exists that a kind of life-span is long, load is large, the reinforced double-row conical bearing of strong shock resistance.
Object of the present invention can be achieved through the following technical solutions: a kind of enhanced-type tapered roller bearing, it is characterized in that, comprise two inner rings, cone spacer, outer ring, two retainers, roller, two described inner rings are arranged side by side in outer ring, described cone spacer is arranged between two inner rings, two described retainers are arranged between outer ring and two inner rings, outer ring inwall is provided with biserial raceway, two interior ring outer walls are respectively established a raceway, described roller is arranged in retainer, two retainers form assembled in the biserial raceway of outer ring with corresponding inner ring respectively.
The external diameter of described outer ring is provided with tank filler sleeve, and the end face of inner ring is provided with oil groove, makes bearing in use obtain sufficient lubrication.
Described roller is provided with multiple, is installed in equably in the pocket hole of retainer.
The diameter of described roller is 52.4mm, and the quantity of roller is 60.
Described inner ring adopts steel for carburizing to permeate Quenching Treatment.
The dynamic load rating of described bearing is Cr 3780kN, and rated static load is Cor 7000kN.
Compared with prior art, the present invention has the following advantages:
1, replace common conical bearing with enhanced-type tapered roller bearing, bearing load is larger, reaches working life more than 1 year, has reduced the cost of enterprise, has improved working efficiency, and coal winning machine is stepped on a new stage, and reaches domestic and international advanced level;
2, adopt enhanced-type tapered roller bearing, quiet dynamic load also can reach respectively Cr 3780kN, Cor 7000kN, and bearing capacity has improved 20% than plain bearing, very suitable coal machine profession heavy duty requirement;
3, adopt steel for carburizing to carry out carburizing and quenching, form soft inside despite one's hard shell feature, make bearing can bear very large impulsive load, fracture strength rigidity is not large, durable in use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with specific embodiment, the present invention is described in detail.
Embodiment
As shown in Figure 1, a kind of enhanced-type tapered roller bearing, comprise outer ring 1, two inner rings 2, cone spacer 3, several rollers 4, two retainers 5, two described inner rings 2 are arranged side by side in outer ring 1, described cone spacer 3 is arranged between two inner rings 2, two described retainers 5 are arranged between outer ring 1 and two inner rings 2, the external diameter of described outer ring 1 is provided with groove, this outer ring 1 inwall is provided with biserial raceway, two inner rings 2 are respectively provided with a raceway, described several rollers 4 are evenly installed in retainer 5 pocket holes, the assembled forming with inner ring 2 is in the biserial raceway of outer ring.
The end face that the external diameter of described outer ring 1 is provided with tank filler sleeve, inner ring is provided with oil groove, so that bearing in use obtains sufficient lubrication; It is 52.4mm that described roller has strengthened roller diameter, and roller number increases to 60, has improved the bearing capacity of bearing, and specified dynamic and static load also can reach respectively Cr 3780kN, Cor 7000kN, has improved 20% than plain bearing; Described inside and outside circle, roller adopt steel for carburizing to carry out carburizing and quenching, form soft inside despite one's hard shell feature, make bearing can bear very large impulsive load, and fracture strength rigidity is not large, durable in use.The present invention adopts reinforced biserial conical bearing to replace common conical bearing, and very suitable coal machine profession heavy duty requirement, is applied to coal winning machine and waves planet head, and coal winning machine is stepped on a new stage, and reaches domestic and international advanced level.
