INA bearing force/maintenance maintenance knowledge introduction

1, INA bearing maintenance, overhaul, and exception handling
In good condition for as long as possible in order to sustain performance bearings, maintenance, overhaul, in order to prevent accidents, it is imperative, ensuring the reliability of operation, increase production, economy. Maintenance best corresponding mechanical running condition of operational standards, conducted on a regular basis. Contents include, monitor the operation condition, supplementary or replacement of the lubricant, demolished checks on a regular basis.
As a matter of maintenance in operation, bearing rotating tones, vibration, temperature, lubricant status, and so on.
2, bearing failures and countermeasures
In General, if the proper use of INA bearing, you can use up to reach fatigue life. But there will be accidents injury prematurely, cannot use situation. This early injury, as opposed to a fatigue life, referred to as the quality limits of failures or accidents. Installed, used, lubrication of origin does not note that foreign objects from external intrusion, axis, case study on thermal effect of insufficient, and so on.
INA bearing damage, such as: roller bearing rings of ribs cards hurt, may consider as reasons, lack of lubricant, is not suitable, for oil discharge structure defects, the intrusion of foreign bodies, bearing large misalignment, shaft deflection, also for these reasons coincide.
1, force together as much as possible through INA bearing axis, this requires a uniform point of application symmetrically and smoothly, through the force of the sphere, or parallel to the axis.
2, the size of the force should be a smooth uniform, not shocks, this requires the use of oil or to impose a tool for smooth tension or pressure, would certainly have a hammer is also do not fall through the copper sleeve soft scrap metal to be buffered, strike force as mitigation. It is best to use copper or copper hammer hammer.
3, to avoid through the rolling force, this required assembling and dismantling the inner ring (shaft washer), through the inner ring of force, when assembling and dismantling the outer ring) by applying pressure in the outer ring.
4, drag force to be sustainable to the extent, such as INA bearings in the installation just stops when filled to the correct location of the bearing force to ensure the rings (washers) the face arrives in bore or axial abutment face, neither squeezed too tightly and unable to load is not in place.
Therefore, only investigated injury, it is difficult to know the real causes of injury. However, if you know the conditions of used machinery, used for bearings, INA bearing structures, to understand the situation before and after the accident around, combined with the bearing damage and several reasons why visits, you can prevent the recurrence of similar accidents.
