Abstract
The present invention relates to a kind of bearings, are related specifically to the ball bearing of compressive resistance.It is made of four parts, outer ring, roller, roller support and outer inner ring, the roller is mounted on ballframe carriage, and roller support is arranged between inner ring and outer ring, it is characterised in that：The roller support at least two rows are constituted, wherein lower row's roller close-packed arrays, the diameter of upper row's roller is required to determine by the overall height of bearing；The upper row per two adjacent rollers between there are gap, which is arranged side by side for row's roller under several.The object of the present invention is to provide a kind of multirow roller bearings, it is intended to solve the bearing inner race phenomenon of rupture of the heavy rotating speed of waiting a moment of big load in the prior art.
Description
Technical field
The present invention relates to a kind of bearings, are related specifically to the ball bearing of compressive resistance.
Background technology
Bearing is the important foundation parts of all kinds of mechanized equipments, its precision, performance, life and reliability are to host
Precision, performance, life and reliability play conclusive effect.In engineering goods, bearing belongs to high-precision product, not only needs
The comprehensive support that the subjects such as mathematics, physics are theoretical is wanted, and needs material science, heat treatment technics, Precision Machining and survey
Amount technology, Numeric Control Technology and the subjects such as effective numerical method and powerful computer technology service for it, therefore
Bearing is a product for representing national science and technology strength again.With the continuous aggravation of bearing mnanufacture industry competition, large size bearing system
It is increased to make M＆A integration and capital operation between enterprise, domestic outstanding Bearing Manufacturing Enterprise is more and more paid attention to industry market
Research, the especially further investigation to industrial development environment and buyers.Just because of this, large quantities of country are outstanding
Bearing mnanufacture brand emerges rapidly, the outstanding figure being increasingly becoming in bearing mnanufacture industry！
Currently on the market for slow rotation and to need big heavy bearing be mostly inner ring fracture occur, this main original
Cause is because caused by unbalance stress.It is known that since what roller contacted with inner ring in bearing is several points, and by
In the unicity of Impact direction, therefore it can often cause the phenomenon of rupture of inner ring.
Invention content
The object of the present invention is to provide a kind of multirow roller bearings, it is intended to solve heavy wait a moment of big load in the prior art and turn
The bearing inner race phenomenon of rupture of speed.
To complete foregoing invention purpose, what Ben Fali was achieved：A kind of multirow roller bearing is made of, outside four parts
Circle, roller, roller support and inner ring, the roller are mounted on ballframe carriage, roller support setting inner ring and outer ring it
Between, it is characterised in that：The roller support at least two rows are constituted, wherein lower row's roller close-packed arrays, the upper row
The diameter of roller is required to determine by the overall height of bearing；There are gaps between the every two adjacent rollers of the upper row, should
Gap is arranged side by side for row's roller under several.This patent on traditional bearing by adding row's roller, and this
The half of the diameter at least diameter of a upper row of roller is arranged, the big stress of the roller of a row upper in this way just is turned to be added in second
On the roller of row, since second row roller is also rotating, and rotating speed is above first row, has so just carried out pressure turn
It moves, to change the direction of power, simultaneously because the roller quantity of next row is greater than a row, therefore, by original several points
Pressure is converted into the pressure of several points, to reduce the possibility of fracture.
Above-mentioned technical proposal is improved further, the diameter of lower row's roller is less than the diameter of upper row's roller,
And it is mutually adjacent between lower row's roller.The holder is made of two side and intermediate dowel, the intermediate connection
Muscle holds row's roller, first has in the bottom skirt section of two side and arranges roller retaining groove below.
This programme fully considers the quantity for how increasing lower row's roller and helps installation stable scheme.
Description of the drawings
Fig. 1 is the part figure of the present invention.
Fig. 2 is the schematic diagram of holder.
Specific implementation mode
In order to further be described the design feature of this patent, it is further described below in conjunction with the accompanying drawings.
A kind of multirow roller bearing is made of four parts, outer ring 1, roller, roller support 4 and inner ring 2, the roller
On ballframe carriage, roller support 4 is arranged between inner ring 2 and outer ring 1, at least two rows of roller support 4
It constitutes, wherein lower 5 close-packed arrays of row's roller, the diameter of lower row's roller 5 is less than the diameter of upper row's roller 3, and lower row rolls
It is mutually adjacent between column 5；The diameter of upper row's roller 3 is required to determine by the overall height of bearing；The upper row is per phase
There are gap between two adjacent rollers, which is arranged side by side for row's roller 5 under several.The holder is by both sides
Wall and intermediate dowel 41 are constituted, and 41 row's of hold roller 3 of intermediate dowel is equipped in the bottom skirt section of two side
Lower row's roller retaining groove 43.This patent on traditional bearing by adding row's roller, and the diameter of this row's roller is at least
It is the half of the diameter of a upper row, the big stress of the roller of a row upper in this way just is turned to be added on the roller of second row, due to the
Two row's rollers are also rotating, and rotating speed is above first row, is so just shifted pressure, to change power
Therefore direction, by original several point pressures, is converted into several simultaneously because the roller quantity of next row is greater than a row
The pressure of point, to reduce the possibility of fracture.
