Abstract
The utility model discloses a double-direction thrust tapered roller bearing, which comprises a shaft washer with double roller paths, two housing washers with plane surface roller paths and two retainer assemblies with a plurality of tapered rollers, wherein the two retainer assemblies with the plurality of tapered rollers are respectively installed on the double roller paths of the shaft washer by the tapered rollers of the retainer assemblies; and the housing washers with the plane surface roller paths are respectively in sliding connection with the tapered rollers on the two retainer assemblies by the plane surface roller paths. The double-direction thrust tapered roller bearing is in a split structure, is easy to install and disassemble and has the advantages of compact structure, high bearing capability and the like.
Description
Technical field
The utility model relates to bearing, particularly relates to a kind of bidirectional thrust tapered roller bearing.
Background technique
Traditional bidirectional thrust tapered roller bearing, its typical structure is the middle blowout patche of plane structure by a raceway, and two raceways are the seat ring of conical surface structure, and two groups of retainers are formed.This bidirectional thrust tapered roller bearing has guaranteed not high rotating accuracy, and it shows has slip when rolling element moves, and can not guarantee rolling element realization pure rolling when work, influences the bearing capacity and the working life of bearing.
The model utility content
The technical problem that the utility model will solve provides a kind of split-type structural, is easy to installing/dismounting, has compact structure, bidirectional thrust tapered roller bearing that bearing capacity is high.
The technological scheme that adopts is:
A kind of bidirectional thrust tapered roller bearing comprises the two raceway blowout patches of band, two seat ring, two retainer assemblies with some tapered rollers of being with the planar surface raceways.Described two retainer assemblies with some tapered rollers are contained on two raceways of blowout patche with its tapered roller respectively, and the seat ring of two band planar surface raceways is slidingly connected through the tapered roller on planar surface raceway and two the retainer assemblies respectively.
Above-mentioned two raceway blowout patches are provided with two ribs.
The elongation line of the blowout patche raceway elongation line of above-mentioned two raceway blowout patches and tapered roller and seat ring raceway intersects on the center line of bearing.
Above-mentioned two raceway blowout patche internal diameters are provided with the axially locating groove.
The characteristics of the utility model are:
1, bearing adopts tapered roller thrust bearing, and seat ring is a planar surface, can guarantee high rotating accuracy.
2, the two raceways of blowout patche band angle have two ribs, and the elongation line of the elongation line of blowout patche raceway and roller and seat ring raceway intersects on the center line of bearing, and slip is arranged when having avoided rotation, can guarantee rolling element realization pure rolling when work.
3, the blowout patche inside diameter surface has keyway, so that guarantee the location of bearing.
This bearing is supporting especially for adapting to a kind of machine driven system.This bearing is a kind of split-type structural, is highly susceptible to installing/dismounting, also has compact structure, bearing capacity advantages of higher simultaneously.
