Abstract
The utility model discloses a four-row tapered roller bearing with taper holes in novel structure, which is formed by four outer circles, three inner circles, three outer partition circles, four-row tapered rollers and four cage components, wherein each two of the outer circles are partitioned by one outer partition circle, the tapered rollers are arranged between the outer circles and the inner circles, and the outer circles and the inner circles are connected through cages. The four-row tapered roller bearing with taper holes is composed of three sets of tapered roller bearings capable of being detached and working independently. The inner diameter of the inner circles is a conical bore with taper 1:12 and tightly matches with the neck of a roll, so that components are good in rigidity and easy to be detached. Further, when a rolling mill performs rough milling, moderate milling and precision milling, rolling forces are different in each workstage or rolling reductions are different in each pass, the combination of three sets of bearings can be changed into a fulcrum bearing formed by a combination of two sets of the bearings to work, thereby reducing consumption of rolling production.
Description
Technical field
The utility model relates to field of bearings, concretely, relates to a kind of four-row tapered roller bearing with taper hole.
Background technique
Common four-row tapered roller bearing is made up of 2 two inner rings, 1 two outer ring, 2 single outer rings, 1 cone spacer, 2 outer ring spacers and 4 row roller cage assemblies, and the inner ring internal diameter is a cylindrical hole.When installing, bearing requires interference fit on roller neck, assembling bearing all compares difficulty, particularly dismantle lasso, roller cage inner assembly, because when bearing is installed, internal diameter and roller neck interference fit are very tight, disassembly-type can only be taken off by force by thwack, and originally some bearing partss that still can repair use are all given and dismounted badly, and often injure the thing generation of roller neck in addition.
Summary of the invention
In order to solve above-mentioned technological deficiency, the purpose of this utility model provides a kind of four-row tapered roller bearing of band taper hole of new structure.
The utility model is made of four outer rings, three inner rings, three outer ring spacers, four-row tapered roller and four retainer assemblies; Separated by outer ring spacer between each outer ring, the outer ring has tapered roller to be linked to each other by retainer with inner ring is middle.
Described retainer comprises pillar, retainer large washer and retainer small washer.
Described inner ring comprises two inner rings and two single inner rings.
Described outer ring is four single outer rings.
Described outer ring spacer is two single outer ring spacers and a two outer ring spacer.
Described inner ring internal diameter is the conical bore of 1: 12 tapering.
Described four-row tapered roller bearing can be taken apart self-existent tapered roller bearing and formed by three covers, and promptly a cover double-row conical bearing and two overlaps single-row tapered roller bearings.
Advantage of the present utility model is:
1, from schematic representation as can be seen, the utility model can be taken apart self-existent tapered roller bearing and formed by three covers, promptly a cover double-row conical bearing and two overlaps single-row tapered roller bearings.
2, the inner ring internal diameter cooperates with roller neck is closely knit for the conical bore with 1: 12 tapering, and the assembly good rigidly is easy to loading and unloading.
3, when milling train carry out roughing, in roll or each operation rolling load of finish rolling varies in size or each reduction in pass when in different size, can make into to be combined into a supporting job by three cover bearings combinations by wherein two cover bearings, reduce Rolling Production consumption.
