Abstract

The utility model discloses a sealed four-row tapered roller bearing and belongs to the technical field of bearings. According to the bearing, a sealing ring is fixedly arranged between two inner rings; a part of the sealing ring is provided with a steel skeleton and the other part of the sealing ring is of a rubber lip structure; the part, with the steel skeleton, of the sealing ring is in interference fit with the inner ring a; the part, of the rubber lip structure, of the sealing ring and the side face of the inner ring b are sealed. The bearing has the beneficial effects that the bearing is convenient to install and when the bearing inner ring assembly is installed, the sealing ring is connected and simultaneously installed; the shortcomings that in an original structure mode 1, the sealing ring is soft and rolls at times during field installation of steel mills are overcome, the problem of seal failure is solved and the larger the pressure between the bearing and a roll is, the tighter the sealing is.

Description

A kind of sealed type four-row tapered roller bearing
technical fielda kind of sealed type four-row tapered roller bearing, belongs to technical field of bearings.
background techniquetraditional bearing is due to project organization reason, and the impurity of bearing outside enters bearing inside, affects bearing working life; Sealed type four-row tapered roller bearing has three positions to need a sealing, and its both sides have between seal ring, two inner rings and have seal ring; Bearing is Spielpassung with coordinating of roll, between four-row tapered roller bearing and roll, there is axial reciprocating to move at work, in the time that axial reciprocating moves, can produce very large pressure of moment, impurity can be clamp-oned in bearing bore, therefore the sealing between two inner rings is very crucial, and this position seal failure occurs often; Between existing two inner rings, sealing configuration mainly contains two kinds of modes below, mode one seal ring is softer, seal ring can not install in bearing producer, can only be in the on-the-spot installation separately of steel mill, in the time installing separately, often there is the seal ring problem of rolling about, mode two these structures are mainly used in preventing that in bearing, grease leaks, and enter poor effect in bearing for anti-impurity.
summary of the inventionin view of the defect that prior art exists, the purpose of this utility model is to provide a kind of sealed type four-row tapered roller bearing that sealing between sealed type tapered roller bearing two inner rings is carried out to optimal design.
For achieving the above object, the technical solution that the utility model adopts is: a kind of sealed type four-row tapered roller bearing, seal ring is fixedly mounted between two inner rings, a seal ring part is provided with Steel Skeleton, another part is rubber lip structure, seal ring is interference fit with Steel Skeleton part and inner ring a, rubber sealing ring lip structure and inner ring b side seal.
A kind of sealed type four-row tapered roller bearing, its beneficial effect is: convenient installation, in the time that bearing inner ring assembly is installed, seal ring connects together and installs simultaneously; Overcome original structure mode one seal ring softer, the defect that there will be seal ring to roll about while being provided with at steel mill scene, has solved the problem that causes seal failure, and the pressure producing between bearing and roll is larger, seals tighter.
