Description
Technical field
The utility model relates to a kind of seal arrangement, relates in particular to a kind of seal arrangement of tapered roller bearing.
Background technique
Tapered roller bearing for bear take radial load be main radially with axial joint load, in lathe manufacture, industry transmission, dynamic power machine, automobile, motor, electrical equipment, metallurgical, mine, in the departments such as communications and transportation and industry, application is very extensive, but, because tapered roller bearing sealing configuration is more complicated, on the one hand, the specialized factory that produces bearing is unwilling to produce the tapered roller bearing that carries seal arrangement, on the other hand, make a lot of clients want to seek to feel extremely difficult with the tapered roller bearing of seal arrangement, thereby being applied in, tapered roller bearing in contaminated environment, has been subject to strict restriction and restriction.
Model utility content
For the present situation of above-mentioned prior art, it is a kind of simple in structure, easy to process that technical problem to be solved in the utility model is to provide, the seal arrangement of the tapered roller bearing of good sealing effect.
The utility model solves the problems of the technologies described above adopted technological scheme: a kind of seal arrangement of tapered roller bearing, comprise inner ring, outer ring, seal ring, retainer and roller, described seal ring and inner ring tight fit connection, sealing circle inside is embedded with a few font skeletons, this skeleton comprises horizontal bar and perpendicular muscle, this skeleton horizontal bar and inner ring large end face outward edge offset, the perpendicular muscle inner plane of skeleton is close to inner ring large end face, leg is extended in the lower end of sealing circle, in leg, there is the Spring Steel Wire supporting of 7 different-diameters, this leg side is curved shape, this leg side contacts with the narrow end surface of outer ring, described retainer is arranged between inner ring and outer ring, described roller is embedded in retainer.
Further, in the horizontal bar of described skeleton, be provided with narrow dead slot.
Further, described seal ring is nitrile butadiene rubber seal ring or acrylic rubber seal ring or viton seal ring.
Compared with prior art, the utility model has the advantage of: the utility model is simple in structure, by the curved design of leg side, make leg band flexible, this leg side contacts with the narrow end surface of outer ring, be sliding fit, can relative sliding, when inner ring rotates together with main shaft, the leg of seal ring forms coordinating of slipper seal with the narrow end surface of outer ring, can play sealing and dustproof effect, in addition, in the horizontal bar of skeleton, be provided with narrow dead slot, make skeleton high resilience, strengthen toughness, increase the service life, the utility model is reasonable in design, practicability is good, be applicable to large-scale promotion.
Accompanying drawing explanation
Fig. 1 is whole sectional view of the present utility model;
Fig. 2 is skeleton enlarged view of the present utility model.
Embodiment
As shown in Figure 1-2, a kind of seal arrangement of tapered roller bearing, comprise inner ring 1, outer ring 2, seal ring 3, retainer 4 and roller 5, described seal ring 3 is fixedly connected with inner ring 1, sealing circle 3 inside are embedded with a few font skeletons 6, this skeleton 6 comprises horizontal bar and perpendicular muscle, these skeleton 6 horizontal bars and inner ring 1 large end face outward edge offset, the perpendicular muscle inner plane of skeleton 6 is close to inner ring 1 large end face, inner ring 1 large end face and outer ring 2 narrow end surfaces are housed in seal space, form complete solid of rotation, leg is extended in the lower end of sealing circle 3, in leg, there is the Spring Steel Wire supporting of 7 different-diameters, this leg side is curved shape, make leg band flexible, this leg side contacts with the narrow end surface of outer ring 2, be sliding fit, can relative sliding, when inner ring 1 rotates together with main shaft, the leg of seal ring 3 forms coordinating of slipper seal with the narrow end surface of outer ring 2, can play sealing and dustproof effect, described retainer 4 is arranged between inner ring 1 and outer ring 2, described roller 5 is embedded in retainer 4, in the horizontal bar of described skeleton 6, be provided with narrow dead slot, this narrow dead slot forms by reinforcing bar is folding, make skeleton 6 high resiliences, increase toughness, described seal ring 3 can be nitrile butadiene rubber seal ring or acrylic rubber seal ring or viton seal ring according to serviceability temperature difference, if bearing temperature is over 120 ℃, should select acrylic rubber seal ring or viton seal ring according to the concrete condition of work temperature rise.
Finally it should be noted that: above embodiment only, in order to the technical solution of the utility model to be described, is not intended to limit; Although the utility model is had been described in detail with reference to previous embodiment, it will be understood by those of skill in the art that its technological scheme that still can record aforementioned each embodiment modifies, or part technical characteristics is wherein replaced on an equal basis; And these modifications or replacement do not make the essence of appropriate technical solution depart from spirit and the scope of each embodiment's technological scheme of the utility model.
