Abstract
The utility model discloses an end surface sealing bearing, aiming at providing an end surface sealing bearing which not only can ensure the long-time sealing property, but also can protect the end surface of an inner ring of a bearing. According to the technical scheme, the end surface sealing bearing is mainly characterized by comprising an outer ring, an inner ring, a retainer, a tapered roller and a sealed insert, as well as a sealing bush, the sealing bush is attached to the outer end of the inner ring, the sealing bush comprises a fixed ring and a sealing end which are perpendicular to each other, the fixed ring is clamped on the inner wall of the inner ring, the sealed insert is composed of a steel skeleton and a sealing ring, the sealing ring comprises two sealing lips and a sealing edge, the two sealing lips are attached to the outer side of the inner ring, and the outer end of the sealing edge is supported against the sealing end. The sealing bush is attached to the outer end of the inner ring, so that the delivery force of a working shaft can be ensured not to be directly contacted with the end surface of the inner ring, so as to prevent the wear of the end surface of the inner ring; the outer end of the sealing edge is supported against the sealing end, so that the majority of impurities are blocked outside, the sealing property can be further improved through the two sealing lips, and the service life of the bearing can be prolonged.
Description
Technical field
The utility model relates to a kind of bearing, and more particularly, it relates to a kind of end face seal bearing with Novel sealing component.
Background technique
Tapered roller bearing is widely used in all kinds of machinery, it has can bear the axial combined loading in footpath, and the feature such as bearing capacity is larger, when bearing working, in order to guarantee the raceway close contact of tapered roller and outer ring, inner ring, must apply a pretightening force to bearing, this pretightening force must act on respectively on the large end face of bearing outer ring and the large end face of inner ring.Therefore, when pretightening force is relayed on the large end face of bearing inner race by working shaft, inner ring end face easily weares and teares, and affects bearing working life, and can produce noise, affects working environment.
And the restriction due to working environment, thereby external impurities easily enters the inner damage that causes bearing of bearing, and the inhibition that lubricated to bearing, thereby reduced bearing working life, although existing bearing has used the seal ring of double-layer seal lip, easy accumulation dirt between salable lip and the side of bearing inner race, after of long duration, can cause the wearing and tearing of sealing lip, lose seal action, thereby reduce bearing working life.
Therefore need a kind of can be permanent assurance sealing and can protect the seal arrangement of bearing inner race end face.
Model utility content
The deficiency existing for prior art, the purpose of this utility model be to provide a kind of can be permanent assurance sealing and can protect the end face seal bearing of bearing inner race end face.
For achieving the above object, the utility model provides following technological scheme: a kind of end face seal bearing, comprise outer ring, inner ring, retainer, tapered roller and sealing inserts, between inner ring and outer ring, be provided with retainer, retainer is provided with tapered roller, end between inner ring and outer ring is provided with sealing inserts, also include stuffing box gland, described stuffing box gland fits in inner ring outer end, described stuffing box gland includes orthogonal retaining ring and sealed end, described retaining ring is closely connected to inner ring inwall, described sealing inserts is comprised of Steel Skeleton and seal ring, described seal ring includes sealing lip and sealing strip, described sealing lip is provided with two, sealing lip fits in inner ring outside, outer end and the sealed end of described sealing strip are inconsistent.
Described outer ring has at the place, outer end of tapered roller the groove that can take lubricating grease in.
Described Steel Skeleton includes connecting end and supporting rib, this Steel Skeleton be close to outer ring inwall for connecting end, described connecting end and supporting rib mutually vertical being " L " type, described seal ring is close on Steel Skeleton and wraps supporting rib.
A kind of end face seal bearing, comprise outer ring, inner ring, retainer, tapered roller and sealing inserts, between inner ring and outer ring, be provided with retainer, retainer is provided with tapered roller, end between inner ring and outer ring is provided with sealing inserts, also include stuffing box gland, described stuffing box gland fits in inner ring outer end, described stuffing box gland includes orthogonal retaining ring and sealed end, described retaining ring is closely connected to inner ring inwall, described sealing inserts is comprised of Steel Skeleton and seal ring, described seal ring includes sealing lip and sealing strip, described sealing lip is provided with two, sealing lip fits in inner ring outside, outer end and the sealed end of described sealing strip are inconsistent.By adopting technique scheme, stuffing box gland fits in inner ring outer end, having guaranteed that working shaft transmission active force makes not can be directly and inner ring end contact, prevent that inner ring end face from wearing and tearing, outer end and the sealed end of sealing strip are inconsistent, and by most sundries blocking outside, two sealing lips further improve sealing, effectively prevent that lubricating grease from leaking and foreign material enter bearing inside, extended the working life of bearing.

Embodiment
With reference to Fig. 1, Fig. 2, the utility model sealing type bearings embodiment is described further.
A kind of end face seal bearing, comprise outer ring 1, inner ring 2, retainer 3, tapered roller 4 and sealing inserts 5, between inner ring 2 and outer ring 1, be provided with retainer 3, retainer 3 is provided with tapered roller 4, end between inner ring 2 and outer ring 1 is provided with sealing inserts 5, also include stuffing box gland 6, described stuffing box gland 6 fits in inner ring 2 outer ends, described stuffing box gland 6 includes orthogonal retaining ring 61 and sealed end 62, described retaining ring 61 is closely connected to inner ring 2 inwalls, described sealing inserts 5 is comprised of Steel Skeleton 51 and seal ring 52, described seal ring 52 includes sealing lip 53 and sealing strip 54, described sealing lip 53 is provided with two, sealing lip 53 fits in inner ring 2 outsides, described sealing strip 54 outer end and sealed end 62 are inconsistent.Stuffing box gland 6 fits in inner ring 2 outer ends, having guaranteed that working shaft transmission active force makes not can be directly and inner ring 2 end contacts, prevent that inner ring 2 end faces from wearing and tearing, sealing strip 54 outer end and sealed end 62 are inconsistent, by most sundries blocking outside, and two sealing lips 53 further improve sealing, just forming three-layer protection layer successively carries out blocking for three times to dust and dirt, dust and dirt are difficult to enter bearing inside, further improve sealing, and effectively prevent that lubricating grease from leaking, extended the working life of bearing.
Described outer ring 1 has at the place, outer end of tapered roller 4 groove 11 that can take lubricating grease in.Groove 11 can be taken lubricating grease in, and lubricated tapered roller 4, reduces the wearing and tearing that tapered roller 4 produces when rolling.
Described Steel Skeleton 51 includes connecting end 55 and supporting rib 56, what this Steel Skeleton 51 was close to outer ring 1 inwall is connecting end 55, described connecting end 55 and supporting rib 56 mutually vertical being " L " type, described seal ring 52 is close on Steel Skeleton 51 and wraps supporting rib 56.Connecting end 55 is interference fitted on 1 inwall of outer ring, can effectively avoid seal ring 52 resiliences and sealing inserts 5 to deviate from, seal ring 52 is close on Steel Skeleton 51 and wraps supporting rib 56, can not make Steel Skeleton 51 and the seal ring 52 separated phenomenons such as seal failure that cause that come off.
