Use the adjustment factor mainly refers to the installation, use and maintenance, repair and other maintenance meets the technical requirements. According to INA bearing installation, use, maintenance, maintenance of the technical requirements for operation of the tapered roller bearings to withstand load, speed, temperature, vibration, noise and lubrication condition monitoring and inspection, abnormal immediately find reasons adjustments to return to normal. Installation conditions are one of the primary factors in the use of the factors bearing is often due to the stress caused by improper installation package bearing between the various parts status changes, bearing in normal operation and the early termination of the state of life

Internal factors mainly refers to the design, manufacturing processes and materials quality three factors determine the quality of the bearing.

Metallurgical quality bearing materials was the main factor in the impact of early bearing failure. As metallurgical techniques (such as bearing steel vacuum degassing, etc.) in progress, raw material quality is improved. Raw material quality factors in bearing failure analysis in the proportion has decreased significantly, but it is still one of the main factors INA bearing failure. Proper selection is still bearing failure analysis of factors must be considered.

Manufacture of bearings generally through forging, heat treatment, turning, grinding and assembly of multi-channel processing. The reasonableness of the processing technology, advanced, will also affect the stability of the bearing life. Which affect the quality of the finished tapered roller bearing heat treatment and grinding processes, often have a more direct relationship with the failure of INA bearings. In recent years, research on the bearing surface metamorphic layer show that the grinding process is closely related to the bearing surface quality.

Sound and control roller bearing raceway sound is when the bearing during operation, a continuous sound slippery rolling body raceway rolling issued, is endemic to the basic sound of all rolling bearings will happen. General INA bearing raceway sound that is sound with other sounds. Ball bearing raceway sound is irregular, the frequency of 1000Hz or more, it is not the main frequency change with the speed, but the sound pressure level increases with speed accelerated.

Sound of a large roller bearings, the rolling sound pressure level decreases with increasing viscosity; and sound of a small roller bearings, the level increased in viscosity to about 20mm2 / s or more, the reduction to be increased. Bearing rigidity, the lower the sound pressure level raceway. The radial clearance is too small, the raceway and the main frequency sound pressure level will decrease as the radial clearance increased dramatically, if you do not want it to sound, the best way is to turn off electricity, Oh, in fact, we can use a number of measures to maximize noise reduction INA bearings, in general, to control the noise tapered roller bearings, we must take countermeasures against the noise of the root causes, in order to receive a permanent cure effect.

More likely to occur in the winter, when INA Bearing by pure radial load, radial clearance prone to big occasions, and with different types of sizes within a particular speed range likely to occur, both will occur continuously Intermittent will appear. Foreign raceway take special processing methods to prevent the emergence of sound jarring, if necessary, this can be used tapered roller bearings, or appropriate to reduce the radial bearing clearance, excellent performance and increase bearing grease to match machine rigid member.
