Abstract
The invention discloses a double row tapered roller bearing for heavy duty occasions, and belongs to the technical field of mechanical bearing parts. The double row tapered roller bearing for heavy duty occasions comprises an integral inner ring (1), a middle space ring (2), a tapered roller group (3) and holders (4) and split outer rings (5). Compared with bearings in the prior art, the double row tapered roller bearing has the advantages of great reduction of friction, improvement of lubrication conditions, improvement of the lubrication quality, reduction of friction heating and energy loss, greatly prolonged life, simple structure, control convenience, high reliability and convenient maintenance.
Description
Technical field
The invention belongs to mechanical bearing part technical field, in particular, belong to a kind of heavily loaded occasion double-row conical bearing.
Background technique
Double-row conical bearing structure is made up of inner ring, outer ring, middle spacer ring, tapered roller and retainer, double-row conical bearing is used on the milling train of each steel rolling mill, bearing working impact, high temperature, at a high speed, under heavy duty, insufficient lubrication, high pressure water the bad working environments condition such as to wash away.Bearing housing end is designed with Sealing, mainly prevents extraneous foreign matter from entering in bearing, as impurity, cooling water, iron scale etc.When firm use new seal, sealing effect is good, but after using a period of time, sealing effect is deteriorated, now as changed Sealing not in time, then sealing effect is very poor, add the reasons such as bearing mounting or dismounting frequent impact sealing, the foreign matters such as the iron scale produced in the operation of rolling, cooling water will enter in bearing, and lubricant grease also can leak, and will cause the non-fatigue ruption of bearing like this, reduce the working life of bearing, also the workload of the frequent fatten of workman can be increased, and the use amount of grease and discharge amount, cause the pollution to environment.
Summary of the invention
The present invention, in order to effectively solve above technical problem, gives a kind of heavily loaded occasion double-row conical bearing.
The heavily loaded occasion double-row conical bearing of one of the present invention, is characterized in that: comprise integrated type inner ring, middle spacer ring, tapered roller group, retainer, split outer ring; Wherein:
Two symmetrical described split outer rings consist of the outer ring of described bearing described middle spacer ring, described middle spacer ring and two described split outer rings have same running shaft; Described integrated type inner ring have respectively two symmetrical groove raceways, two groove raceways on described integrated type inner ring have the described tapered roller group corresponding with it and described retainer respectively, the described tapered roller group matched with described retainer is installed respectively, the fillet of leaning now to one side, then to the other of described inner ring endoporus in the groove raceway of each described integrated type inner ring;
Be provided with the separate planes raceway arranging described tapered roller assembly respectively with two and close in the circle internal diameter of two described split outer rings, in described plane raceway, evenly scribble polyvinyl acetate; Be provided with two the independent grooves raceways arranging described tapered roller assembly respectively with two and close in the circle external diameter of described integrated type inner ring, in described groove raceway, evenly scribble polyvinyl acetate;
Have a rectangular recess outside the circle of described middle spacer ring, be evenly distributed with the oil hole pointing to the described middle spacer ring center of circle in described rectangular recess, described oil hole quantity is 4 or 8, described oil hole has the internal thread for installing seal plug.
The present invention is compared with prior art: greatly reduce friction, improve lubricating condition, improve the quality of lubrication, reduce frictional heating and energy loss, thus substantially increase bearing life, the advantages such as structure is simple, control is convenient, reliability is high, easy to maintenance.
