Description
Technical field
This utility model belongs to cylinder roller bearing technical field, particularly relates to a kind of biserial crossed cylindrical roller bearing.
Background technology
At present, common crossed cylindrical roller bearing is single-row bearing, by (or two) outer ring, one (or two)
Inner ring, the cylindrical roller of one group of decussation and spacing block composition, separate with spacing block between two adjacent rollers.Outer ring
The raceway of (or inner ring) and ring face angle are 45 °, and between two row raceways, angle is 90 °.This raceway adds to be had very man-hour
The most inconvenient, (45 ° of angles do not have conventional measuring method, can only rely on to first have to ensure to be 45 ° by the angle of raceway and ring face
Large-scale contourograph is measured), secondly also to ensure the angle 90 ° between two row raceways.This bearing to be mainly characterized by cross section little, knot
Structure is compact, in being mainly used in, the conventional turntable of low precision, and joint part of robot etc..But, this class bearing is owing to cutting
Face is little, and axial dimension is limited, and the rigidity causing axle system is not enough, for needing the precision aid of high rigidity high-precision axle system occasion
Device, accurate medical apparatus and instruments, the operating mode such as large-scale air equipment can not be suitable for.
It addition, Chinese utility model patent " double crossed cylindrical roller bearing ", publication number CN 202560815 U ", its
It is by being correspondingly arranged on the V-arrangement raceway that two row's structures are identical, described V respectively with inner ring outer-diameter end face at the internal diameter end face of outer ring
The angle of shape raceway is 90 °, and then makes this bearing have higher radial and axial bearing capacity and bigger power of toppling
Square.But, should " double crossed cylindrical roller bearing " there is problems in that
The first, be 45 degree of angles due to rotation axis and the end face of roller, thus single roller can not bear axial force or
Radial force；Roller is also 45 ° of angles due to roller roller axis direction and end face inside raceway when rotated, and rolling element is on edge
In the diametric(al) of raceway, the linear velocity of the bus everywhere of raceway is different, causes roller to have skidding existing when rotated on raceway
As, the skidding of every roller is superimposed and causes Bearing inner to generate heat, and bearing temperature quickly raises, thus causes bearing life
Shorten, premature failure；
The second, inner ring and outer ring is all overall, and causing that the precompressed amount of bearing is limited (can be to bearing roller when precompressed amount is the biggest
Assembling cause difficulty), so the precompressed amount of the rigidity of bearing and bearing is the most limited；
3rd, outer ring and inner ring are monolithic construction, and assembling roller is difficult, and the direction adjusting roller is not easy to, plug
On son, the degree of agreement of raceway part and lasso raceway is affected by the cooperation degree of tightness in stopper external diameter and lasso aperture, and roller rotates
Time unstable.

The angle of circle plane is 45 °, also wants special contourograph to measure.
Biserial crossed cylindrical roller bearing of the present utility model and " double crossed cylindrical roller bearing " (publication number CN
202560815 U) compare, there is advantage highlighted below:
1, by changing the angle of raceway and end face, and the angle of raceway so that each roller can bear axle
To power and radial force.
2, by adjusting the size of the small end face of outer ring, in that context it may be convenient to adjust the preload of roller, in particular for height
Load and the workplace of high rigidity, preload is the biggest, and in the case of the equal technique of equivalent material, the accuracy life of bearing is just
More lasting, thus reach to reduce the purpose in customer care cycle.
3, the cylindrical roller in the raceway of this utility model bearing, the linear velocity of wherein parallel with bearing axis roller is
Consistent, skidding when roller rotates can be eliminated；But adjacent roller, namely axis is vertical with set coil axis
Roller still has this situation, this situation can rely on Bearing inner height preload (second advantage, bearing can have
High preloading is contemplated to reduce the skidding that roller rotates), increasing should with inner ring and contacting of outer ring raceway when roller rotates
Power so that roller is only along the direction rotation of raceway and revolution.
4, raceway uses bus finishing line design to avoid producing during discontinuity stress concentration phenomenon, bus finishing line
Roller is when no load condition, and roller and raceway contact are in a bit, or are contacted with one section of line and two ends do not contact；Stand under load is followed by
Contacting surface is usually the rectangle of nonocclusive ellipse or approximation, eliminate or reduces edge stress and concentrates, it is to avoid raceway or roller
Fatigue failure in advance, it is possible to effectively extend the service life of bearing.
5, it is two halves formula structures due to inner ring or outer ring, treats roller and spacing block to install afterwards and be loaded on other half set
Circle, so the skimble-scamble phenomenon of raceway position on the raceway not existed on stopper and bearing ring.
