Background technique
Bearing is a kind of important spare part in contemporary mechanical equipment；Its major function is to support mechanical rotary body, is reduced
Coefficient of friction in its motion process, and guarantee its rotating accuracy.
Bearing is generally divided into: sliding bearing, oscillating bearing, rolling bearing, deep groove ball bearing, angular contact ball bearing, aligning
Ball bearing, thrust ball bearing, bidirectional angular contact thrust ball bearing, thrust roller bearing, needle bearing, roller bearing units, tune
Heart roller bearing, flange bearing, combination bearing and linear bearing etc..
Tapered roller bearing belongs to divergence type bearing, and the inside and outside circle of bearing all has tapered raceway；The class bearing is by being filled
The columns of roller is divided into the different structural shape such as single-row, biserial and four-row tapered roller bearing；Single-row tapered roller bearing can
To bear radial load and single direction axial load；When bearing bears radial load, it will generate an axial thrust load, institute
To be balanced when needing another that can bear the bearing of opposite direction axial force.
Hot rolling is for cold rolling, and cold rolling is the rolling carried out below recrystallization temperature, and hot rolling be exactly

Processing performance；Between needing the frictional force for using hot-rolling mill rotary roller that rolled piece is dragged in roll in course of hot rolling, while by rolling
The pressure that roller applies makes rolled piece that compressive deformation occur between two rolls or more than two rolls, due to needing very big pressure
Power, so roll both ends are generally supported using double row tapered roller bearing, roller temperature is brought rapidly up in the hot rolling,
It is transmitted on bearing, so that the fever expansions such as bearing outer ring, taper roller, bearing inner race, while bearing also transfers heat to
On the one hand bearing block, double row tapered roller bearing expanded by heating reduce hot rolling precision, reduce product qualification rate, another aspect biserial
For tapered roller bearing from bearing block since material is different, the opposite coefficient of expansion is also different, the size that bearing block is radially expanded
The generally higher than size of double-row tapered roller bearing outer ring expansion leads to have larger gap between bearing outer ring and bearing block,
So that bearing is easy to happen skidding during operation, bearing operation stability is influenced, reduces the precision that roll rolls product, drop
Low company's benefit.
