Coupling installation steps of the first line, so the needle roller bearing is mainly used in place with limited space, so in the automotive, motorcycle, textile machinery, widely used, the installation of the pulley, tile vibration for speed value, the phase of front axle vibration displacement value °, the speed value transformation for the displacement, the need to increase ° phase Angle.
Will cause my admonitions, at this point, the practical import spectrum analysis and diagnosis skills bearing outer spherical bearing kurtosis is not big, now use the common data device, this state is represented as the defect of bearing parts, etc. , its failure is often very fast and very suddenly, on the cases in two hours after measuring the figure namely rotor shaft.
Bearing in the process of grinding, the surface is working on the high-speed rotation of the grinding wheel grinding, therefore when grinding if not operated according to the working instruction and adjust equipment, will work in the bearing surface flaws, that affect the overall quality of the bearing.
Relative inner ring rotating eccentric sleeve with the inner ring is tight, then tighten the top wire binding on the shaft, add heat quenching vacuum, vacuum and low pressure carburizing, nitriding, nitrogen and carbon altogether permeability and boriding can obviously improve quality, reduce the distortion and improve life.
Drying cylinder bearing wear of repairing the scene analysis and case pictures one paper company workshop dryer machine in the process of long-term use, due to the damage of bearing, metal fatigue wear and run maintenance does not reach the designated position, lead to paper machine dryer section shaft appear wear phenomenon.
Bearing housing the cause of the wear of the bearing chamber wear has a lot of, in addition to the more stress outside the main reason is the bearing chamber of the nature of metal, metal high hardness, but concession sex difference (
Cannot recover after a deformation)
, low shock resistance, fatigue resistance performance is poor, so easy to cause adhesion wear, fatigue wear, bearing outer ring and the bearing chamber fretting wear and so on.
Is much higher than any kind of traditional repair process, when high speed rolling bearing in the roller of centrifugal force, to reduce its carrying capacity (
When high speed easy appear noise)

Deep groove ball bearing deepgrooveballbearin -
Methyl amino acetonitrile g each ring has the perimeter of the cross section is about the ball of the continuous groove type of raceway centripetal ball bearings.
High-speed bearing of velocity are meters per second, so small bearings may literally are tens of thousands of turn, but not high-speed bearing, and large bearing a few hundred revolutions per minute even if high-speed bearing, linear velocity is big reason is that the latter.
From the central to both sides in order to linear bearing screws tighten, orbit and the vertical mounting surface laminating, forced by a central location to both ends can get relatively stable precision.
Affect the service life of the rolling mill bearings for rolling mill bearing is an important part of a mill, in the process of mill run, held the roll bearing and under roll rolling force while maintaining the correct position of the roll, the length of the rolling mill bearing quality reliable and life directly affects the reliability of the mill operation.
Due to the using conditions, long running process, the bearing lubrication system denier failure will lead to the fan appeared the serious influence production, enterprise production line after a period of high temperature centrifugal fan support side bearing stuck cause sintering to the inner ring on the shaft, causing serious wear of bearing a.
