Abstract
The utility model relates to an eccentric twinrow taper roller axletree unit which is composed of a double cup, an obturating ring, a roller, a holder, a cone spacer and an inner track, the surface of the double cup functions as the running surface, two ends of the double cup are provided with sealing rings that adopts[w19] the method of steel plate single lip sealing, the eccentric shaft is fixedly connected with the inner track by a screw nut, a plurality of backing up steel balls are arranged between the eccentric shaft and the fastening nut; the eccentric shaft and the twinrow taper roller axletree are assembled together through the fastening nut and the backing up steel balls, constituting a realizable rotary axletree unit. Compared with the traditional axletree, the utility model has the advantages that the load of the axletree is improved by twenty percent, the working life is prolonged by fifty percent, the reliability is improved, and the utility model can be easily dismounted and maintained.
Description
Technical field
The utility model relates to technical field of bearings, relates to a kind of eccentric double row tapered roller bearing unit
Background technique
Bearing is the crucial mechanical basic part of the national economic development, is widely used in national economy every field such as Aero-Space, railway, automobile, tractor, lathe, motor, boats and ships, oil-well rig, mine, metallurgy, milling train, chemical industry, press for extracting juice sugar, papermaking, printing, textile machinery.To guarantee product long-life, high reliability on the one hand, on the other hand to lightweight, blocking, intelligent development.The main research contents of technical field, research and development are used for the supporting and import substitution new product of main frame exactly, to help the product requirement of massive production, tapered roller bearing is as common support connecting piece at present, its inside and outside footpath cooperates with axle and axle bed as fitting surface, and the specific (special) requirements occasion lacks the bearing new varieties; Seal structure complex, form is more, if realize sealing, the bearing capacity of certain influence bearing; Bearing is concentric revolution, need increase extra accessory to the eccentric use occasion that requires is arranged.
Summary of the invention
The purpose of this utility model is to propose a kind of eccentric double row tapered roller bearing unit.
The technical solution of the utility model is: a kind of eccentric double row tapered roller bearing unit, form by outer ring with double raceway 2, seal ring 3, roller 4, retainer 5, cone spacer 7 and inner ring 8, outer ring with double raceway 2 outer surfaces are as working surface, the seal ring 3 that outer ring with double raceway 2 two ends are provided with adopts steel plate frame list lip seal form, eccentric shaft 1 is connected with inner ring 8, and fixing by tightening nut 9, be provided with locking steel ball 6 between eccentric shaft 1 and the tightening nut 9; By tightening nut 9 and locking steel ball 6 eccentric shaft 1 and biserial O-ring taper roller bearing are combined, constituted one and can realize rotating bearing unit.
The beneficial effects of the utility model are: the utility model is compared traditional bearing load and has been improved 20%, %, and the life-span prolongs 1.5 times, and the reliability height, is easy to dismounting and maintenance.The successful development of eccentric double row tapered roller bearing unit and application not only createed considerable economic, and social benefit are more obvious.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Among the figure, 1, eccentric shaft, 2, outer ring with double raceway, 3, seal ring, 4, roller, 5, retainer, 6, locking steel ball, 7, cone spacer, 8, inner ring, 9, tightening nut.
Embodiment:
As shown in Figure 1, the utility model is made up of outer ring with double raceway 2, seal ring 3, roller 4, retainer 5, cone spacer 7 and inner ring 8, outer ring with double raceway 2 outer surfaces are as working surface, the seal ring 3 that outer ring with double raceway 2 two ends are provided with adopts steel plate frame list lip seal form, eccentric shaft 1 is connected with inner ring 8, and fixing by tightening nut 9, be provided with locking steel ball 6 between eccentric shaft 1 and the tightening nut 9; By tightening nut 9 and locking steel ball 6 eccentric shaft 1 and biserial O-ring taper roller bearing are combined, constituted one and can realize rotating bearing unit.
