Abstract
The utility model discloses an end-sealed tapered roller bearing, aiming at providing an end-sealed tapered roller bearing in which a sealing ring is directly arranged on the retaining edge of an inner ring so as to improve a sealing effect. According to the technical scheme, the end-sealed tapered roller bearing is mainly characterized by comprising an outer ring, an inner ring, a retainer, and a tapered roller, as well as a sealing piece, wherein the sealing piece consists of a T-shaped steel skeleton and a sealing ring, the steel skeleton consists of a connecting end and a supporting rib which have an integrated structure, the sealing ring is provided with sealing lips. The T-shaped steel skeleton with the integrated structure has higher rigidity, the connecting end of the steel skeleton is in interference fit with the retaining edge of the inner ring, thus being capable of effectively avoiding the release of the sealing piece; the sealing ring is clung onto the steel skeleton to wrap the supporting rib so as not to cause the sealing failure phenomenon due to the falling and separation of the steel skeleton and the sealing ring; the sealing lips are attached to the side surface of the outer ring, thus being capable of preventing dust from permeating clearances and entering the interior of the bearing; the end-sealed tapered roller bearing is simple and reasonable in structure.
Description
Technical field
The utility model relates to a kind of tapered roller bearing, and more particularly, it relates to a kind of tapered roller bearing of end part seal.
Background technique
At present, the large part of conventional tapered roller bearing Dou Shiyou outer ring, inner ring, retainer, tapered roller etc. four forms, itself is not with sealing configuration its bearing, there is no sealing function, cannot stop foreign material to enter bearing inside, the cleaning ambient requiring during bearing operation is not being met, often cause that bearing lost efficacy in advance, do not reach desired life the actual life of bearing, therefore this tapered roller bearing that there is no sealing configuration, need to arrange separately in the outside of bearing seal arrangement become people in the urgent need to.
Model utility content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of and directly seal ring is assemblied on inner ring rib, improves the tapered roller bearing of the end part seal of sealing effect.
For achieving the above object, the utility model provides following technological scheme: a kind of tapered roller bearing of end part seal, comprise outer ring, inner ring, retainer, tapered roller, between inner ring and outer ring, be provided with retainer, retainer is provided with tapered roller, also include Sealing, described Sealing is comprised of Steel Skeleton and seal ring, described Steel Skeleton is comprised of connecting end and the supporting rib of integrative-structure, what this Steel Skeleton was close to inner ring rib is connecting end, described connecting end and supporting rib be the vertical T-shape that is mutually, described seal ring is close on Steel Skeleton and wraps supporting rib, sealing circle is provided with sealing lip, described sealing lip fits in side, outer ring.
The connecting end internal diameter of described Steel Skeleton is provided with groove.
The outer end of described seal ring, its outside dimension equates with bearing outer ring outside dimension.
A kind of tapered roller bearing of end part seal, comprise outer ring, inner ring, retainer, tapered roller, between inner ring and outer ring, be provided with retainer, retainer is provided with tapered roller, also include Sealing, described Sealing is comprised of Steel Skeleton and seal ring, described Steel Skeleton is comprised of connecting end and the supporting rib of integrative-structure, what this Steel Skeleton was close to inner ring rib is connecting end, described connecting end and supporting rib be the vertical T-shape that is mutually, described seal ring is close on Steel Skeleton and wraps supporting rib, sealing circle is provided with sealing lip, described sealing lip fits in side, outer ring.By adopting technique scheme, the T-shape Steel Skeleton of integrative-structure, make Steel Skeleton more have rigidity, the connecting end of Steel Skeleton is interference fitted on inner ring rib, can effectively avoid Sealing to deviate from, and seal ring is close on Steel Skeleton and wraps supporting rib, can not make Steel Skeleton and the seal ring separated phenomenons such as seal failure that cause that come off, sealing lip fits in side, outer ring, can prevent that dust from seeing through gap and entering bearing inside, simple and reasonable for structure.
Accompanying drawing explanation
Fig. 1 is the structural representation of the tapered roller bearing of the utility model end part seal.
Fig. 2 is the A portion structure for amplifying schematic diagram of Fig. 1.
Figure Zhong1-outer ring, 2-inner ring, 3-retainer, 4-tapered roller, 5-Sealing, 21-inner ring rib, 51-Steel Skeleton, 52-seal ring, 53-connecting end, 54-supporting rib, 55-sealing lip, 56-groove.
Embodiment
With reference to Fig. 1, Fig. 2, the tapered roller bearing embodiment of the utility model end part seal is described further.
A kind of tapered roller bearing of end part seal, comprise outer ring 1, inner ring 2, retainer 3, tapered roller 4, between inner ring 2 and outer ring 1, be provided with retainer 3, retainer 3 is provided with tapered roller 4, also include Sealing 5, described Sealing 5 is comprised of Steel Skeleton 51 and seal ring 52, described Steel Skeleton 51 is comprised of connecting end 53 and the supporting rib 54 of integrative-structure, what this Steel Skeleton 51 was close to inner ring rib 21 is connecting end 53, described connecting end 53 and supporting rib 54 be the vertical T-shape that is mutually, described seal ring 52 is close on Steel Skeleton 51 and wraps supporting rib 54, sealing circle 52 is provided with sealing lip 55, described sealing lip 55 fits in 1 side, outer ring.In this design proposal, the T-shape Steel Skeleton 51 of integrative-structure, make Steel Skeleton 51 more have rigidity, connecting end 53 is interference fitted on inner ring rib 21, can effectively avoid Sealing 5 to deviate from, and be convenient to the installation and removal of bearing under various device and ambient conditions, seal ring 52 is close on Steel Skeleton 51 and wraps supporting rib 54, can not make Steel Skeleton 51 and the seal ring 52 separated phenomenons such as seal failure that cause that come off, sealing lip 55 fits in 1 side, outer ring, can erect defence line like this, prevent that dust from seeing through gap and entering bearing inside, simple in structure, rationally.
Connecting end 53 internal diameters of described Steel Skeleton 51 are provided with groove 56.In this design proposal, groove 56 can strengthen the friction of connecting end 53 and inner ring rib 21, improves the join strength of Steel Skeleton 51 and inner ring rib 21, can effectively avoid Sealing 5 to deviate from.Also or can adopt by toothed surfaces or netted and strengthen friction and further improve its join strength.
Described seal ring 52 outer end, its outside dimension equates with bearing outer ring 1 outside dimension.In this design proposal, designed bearing is positioned in casing carrying axis hole, seal ring 52 outer end and casing carrying axis hole closely sealed connection of face, can effectively blocks dust and dirt and enter bearing inside through gap.
