Description
Technical field
The utility model belongs to roll technical field of rolling bearings, and in particular to a kind of four row cylinder is combined with taper roller
Bearing.
Background technology
Roll bearing is one of basic components of efficient milling train, the bar that be restricted due to roll bearing in radial dimension
Very big roll-force is born under part, therefore, four-line column roller bearing or four row are used the rolling bearing used on milling train more
Taper roll bearing.The radial direction bearing capacity of four-line column roller bearing is bigger than the four-row tapered roller bearing of identical size.Four
Row tapered roller bearing can bear axial load while bearing radial load, but four-line column roller bearing can not bear axial direction
Load, it is necessary to the bearing for bearing axial load is installed on roll, competence exertion four-line column roller bearing bears radially to carry
The characteristics of lotus is big, can so make roll assembling structure complicated.
Meanwhile, in the production and application of existing milling train, the working life that generally existing bearing is far below projected life, very
To the phenomenon for bearing burnt major accident occur, its reason is load between the row of multiple row rolling bearing in actual use
Skewness, the load that the bearing away from body of roll side is born is smaller, bears excessive load close to roll barrel side bearing, causes
Bearing premature breakdown.
The content of the invention
The purpose of this utility model is to provide a kind of four new row cylinders and taper roller combination bearing, can effectively gram
Take shortcoming present in prior art.
What utility model of the present invention was achieved in that, such as Fig. 1, it is characterized in that：Biserial cylindrical roller bearing inner ring 1 and biserial
Bearing inner spacer 7 is installed between tapered roller bearing internal ring 14；Left and right row tapered roller 11,9 is justified by left and right row respectively
Roller cage 13,8 is bored to be arranged on double-row conical bearing inner ring 14；Left and right line column roller 6,2 passes through cylindrical roller
Retainer 4 is arranged on the inside of three-row bearing outer ring 3；Rolled together with left and right line column roller 6,2 and cylinder three-row bearing outer ring 3
Sub- retainer 4 is arranged on the periphery of Biserial cylindrical roller bearing inner ring 1 and right row tapered roller 9；Left column taper roll bearing
Outer ring 12 is sleeved on the periphery of left column taper roller 11, between three-row bearing outer ring 3 and left column taper roll bearing outer ring 12
Oil Guide outer ring spacer 10 is installed.Be formed with the excircle of three-row bearing outer ring 3 lubrication hydraulic fluid port 5 and left and right line column roller 6,2 it
Between cavity connection；As shown in Fig. 2 oil storage grooves 10.1 are formed with the middle of the excircle of the Oil Guide outer ring spacer 10, by radially
Cavity between oil guiding hole 10.2 and left and right inclined hole 10.3,10.3 ' and left and right row tapered roller 11,9 is connected.
The utility model advantage and good effect are：
(1) according to roll in rolling work both by radial load, while the characteristics of bearing axial load, the present invention is used
The four row bearing that cylinder is combined with taper roller, and Biserial cylindrical roller bearing is arranged close on the roll neck of the body of roll, change
Shaft strength situation has been apt to it, has simplified roll assembling structure, has improved the bearing capacity and service life of bearing.
