Abstract
The utility model relates to a full-sealing four-row conical roller bearing which belongs to the technical field of a rolling bearing. Two symmetrical second sealing retainer rings are added in the middle of the four rows of bearings, and an oil hole is arranged in the middle of the second sealing retainer rings; an inner ring is provided with an oil tank; the outer diameter of each second sealing retainer ring is provided with a sealing ring, and the second sealing retainer ring is provided with a sealing assembly on one side near bearings. A roller, a big washer of a holder, and a small washer of the holder are arranged on the inner ring; one end of a support column, which is provided with screw threads, penetrates through a center hole of the roller and is screwed into a thread hole of the big washer of the holder, and the other end of the support column is welded with the small washer of the holder, is put in an outer ring spacer then and is put in an outer ring then; the sealing assembly and first sealing retainer rings are put in after assembled, and the second sealing retainer rings and the sealing assembly are put in after assembled. The utility model has the advantages that the utility model meets requirements of sealing and lubrication, the service life of a shaft and a bearing is extended, and the utility model is suitable for a full-sealing four-row conical roller bearing.
Description
Technical field
The utility model belongs to technical field of rolling bearings.
Background technique
In metallurgical, mine and milling train etc. be operated in equipment under the mal-condition, often use four row O-ring taper roller bearings.At present, most of four row O-ring taper roller bearings are mainly taked following sealing means: the one, and four row bearing is sealed at both ends, and the middle spacer ring that adopts seals.The 2nd, four row bearing is sealed at both ends, and inner ring digs the groove sealing; Though these two kinds of bearings have satisfied sealing, in order to protect critical main shaft not to be damaged, the surface of contact of bearing and main shaft need be lubricated sometimes, and above-mentioned two kinds of bearings can't satisfy the inner ring aperture and the lubricated requirement of synapsis that is coupling.
Summary of the invention
The purpose of this utility model just provides a kind ofly can satisfy four row conical bearing seal requests, can satisfy the lubricating requirement of surface of contact between the inner ring and the diameter of axle, the hermetically sealed four-row tapered roller bearing that prolongs axle and the working life of bearing again.
Technical solution of the present utility model is, hermetically sealed four-row tapered roller bearing is made of inner ring 1, pillar 2, retainer small washer 3, black box 4, first Sealing shield ring 5, outer ring 6, retainer large washer 7, outer ring spacer 8 and roller 9, in the middle of four row bearing, increase by second Sealing shield ring 10 of two symmetries, be provided with oilhole in the middle of second Sealing shield ring 10, inner ring 1 is provided with oil groove, second Sealing shield ring, 10 external diameters are provided with seal ring 11, the second Sealing shield rings 10 and are provided with black box near the bearing side; Pillar 2 threaded ends pass roller 9 center holes and are threaded with retainer large washer 7 usefulness, pillar 2 the other ends and 3 welding of retainer small washer, and roller 9, retainer large washer 7 and retainer small washer 3 place on the inner ring 1; Outer ring spacer 8 places roller 9 outsides, and outer ring 6 places retainer large washer 7 outsides, and the black box 4 that assembles and first Sealing shield ring 5 place the end face of retainer small washer 3, and second Sealing shield ring of assembling with black box 10 is arranged at bearing row centre.
The beneficial effect that the utility model reached is: owing to can make the bearing inner race and the surface of contact of axle obtain oil lubrication under the prerequisite of sealing; on the one hand; increased the working life of bearing; the early failue of having avoided impurity to enter bearing that bearing causes, on the other hand, when bearing inner race produces wriggling with axle; because the existence of lubricant oil is arranged; reduced the sliding friction of the bearing inner race and the diameter of axle, critical axle is effectively protected, the damage of axle when having avoided bearing wriggling to take place with axle.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is further specified.
Fig. 1 is a plan view of the present utility model.
Among the figure: 1. inner ring, 2. pillar, 3. retainer small washer, 4. black box, 5. first Sealing shield ring, 6. outer ring, 7. retainer large washer, 8. outer ring spacer, 9. roller, 10. second Sealing shield ring, 11. seal rings.
Embodiment
Hermetically sealed four-row tapered roller bearing is by inner ring 1, pillar 2, retainer small washer 3, black box 4, first Sealing shield ring 5, outer ring 6, retainer large washer 7, outer ring spacer 8 and roller 9 constitute, in the middle of four row bearing, increase by second Sealing shield ring 10 of two symmetries, get out oilhole in the middle of second Sealing shield ring 10, simultaneously, inner ring 1 has oil groove, lubricant oil can enter the contacting point of inner ring and axle by the oil groove that gets out oilhole and inner ring in the middle of the Sealing shield ring, the surface of contact that is covered with bearing and axle again by the oily line of inner ring, second Sealing shield ring, 10 external diameters are provided with seal ring 11, the second Sealing shield rings 10 and are provided with black box near the bearing side; Roller 9, retainer large washer 7 and retainer small washer 3 are arranged on the inner ring 1, pillar 2 threaded ends are passed roller 9 center holes to screw in retainer large washer 7 tapped holes, pillar 2 the other ends and 3 welding of retainer small washer, put into outer ring spacer 8 then, put into outer ring 6 again, will black box 4 and 5 assemblings of first Sealing shield ring after reinstall, will second Sealing shield ring 10 with the black box assembling after pack into.
