Using INA tapered roller bearing in the process of the solution of the fault principle

Use factors mainly refers to install, use, maintenance, maintenance, repair and so on meets the technical requirements.
According to INA bearing installation, use, maintenance, maintenance of technical requirements, the operation of the tapered roller bearing on the load, speed, temperature, vibration, noise and lubrication condition monitoring and inspection, found that abnormal immediately to find the reason, adjustment, so that it is back to normal.
Installation condition is one of the primary factor of use factor, bearing is often caused by improper installation of a complete set of change the stress of bearing between various parts, bearing in the abnormal state of operation and the service life of the early end internal factors mainly refers to the structure design, manufacturing process and material quality and so on three major factors in determining the quality of bearing.
Bearing materials of metallurgical quality were the main factors influencing the premature failure of the bearing.
As metallurgy technology,
For example, the bearing steel vacuum degassing, etc. )
Progress, raw material quality is improved.
Raw material quality factor in the bearing failure analysis share has declined obviously, but it is still the INA bearing failure of one of the main influence factors.
Select material adequacy is still bearing failure analysis factors must be considered.
Bearing manufacturing generally go through forging, heat treatment, cutting, grinding and assembly, and multi-channel processing operations.
The rationality of the processing technology, advanced, stability will also affect the service life of bearing.
Which affects the quality of finished product tapered roller bearing, heat treatment and grinding process often has more direct relation with INA bearing failure.
In recent years the study of metamorphic layer of bearings working surface show that the grinding process and is close to the surface quality of the bearing.
Bearing raceway groove sound sound and its control method is when bearing is running, rolling on the surface of the raceway of the rolling element and a line of continuous sound, is unique to occur in all rolling bearings of the basic sound.
General INA bearing ring raceway is combined with other sounds.
Ball bearing raceway is irregular, frequency above 1000 hz, its main frequency does not change with speed, but the sound pressure level increases with speed to speed up.
Raceway large import bearings, the rolling sound of sound pressure level decrease with the increase of the viscosity;
The raceway small bearings, the sound pressure level in the viscosity increases to about 20 was/s above, from decreased to increase somewhat.
The rigidity of the bearing, the greater the raceway of sound pressure level is lower.
Such as radial clearance is too small, the sound pressure level and the main frequency of the raceway ring can increase sharply with the decrease of radial clearance, if you don't want it to have a voice, the best thing to do is to turn off the electricity, ha ha, actually we can use some measures to maximize reduce the noise of INA bearings, generally speaking, to control the noise of the tapered roller bearing, it must take countermeasures in view of the source of the noise, and to receive the cure effect.
Happen more easily in winter, when the INA bearing of pure radial load, the radial clearance are prone to big occasions, and with different size, easy to happen in a certain speed range, both continuous and intermittent.
External ring raceway take special processing method can prevent the occurrence of roll ring, can choose this kind of tapered roller bearings, if necessary or appropriate to reduce bearing radial clearance, the use of high performance grease and improve to suit the bearing parts of rigidity.
