Tapered roller bearings noise is normal phenomenon it

In fact, many people may have found the problem, when turning on the machine, we can hear from the Backing bearings raceway loud noise, so we were a bit worried that the machine is not what's wrong, ah still not normal. In fact, we do not have to worry too much about this issue, under normal circumstances, like some of the seven types of bearings will issue a rolling sound of 30 decibels, and it is the noise characteristics and regularity, the first noise it emits sound and not every time, is a variety of random sounds, because the tapered roller bearing each machine running speed and various other factors that are not fixed, so the sound is not the same. But no matter what changes speed, the noise is almost constant while the main frequency sound pressure level is increased with the increase with the speed, when the bearing raceways total sound pressure level is lower, even if the speed increases, the total sound pressure level also increased little, overall, in bearing noise is a normal thing, do not worry too much.Tapered roller bearings noise is normal phenomenon it
