Tapered roller bearings in the course of work, make some noise. Slight noise is to be allowed in. Lots of long working hours of FAG bearings, for a variety of reasons will issue a comparison of impact noise, usually in this case, bearings are damaged.
Different models of the tapered roller bearing noise on the job size is different, these noises are FAG bearings in operation friction generated when, in fact, these noises through the process can be controlled.
Under normal circumstances, tapered roller bearings the noise from the main road and the rolling, rolling it issued during the rolling process. Raceway is the primary voice of the running of the bearing. General size and rigidity of bearing Raceway and directly related to the radial internal clearance of the bearing itself.
Raceways of tapered roller bearings without rules, higher frequency, but the frequency rate unchanged. Roller bearing itself-the size of the performance-related, and some noise of tapered roller bearings, can be specially processed by external Raceway and reduce the radial clearance, colleagues can be equipped with a suitable grease, reducing the friction roller, but also can improve the rigidity of the tapered roller bearing parts.
In addition, the tapered roller bearing parts bearing noise has some performance implications. Selection of structure material compliant cage also helped to reduce the radial internal clearance of the bearing, thereby reducing the impact of rolling noise.
When select tapered roller bearings, you can consider the bearing noise when running, so when buying FAG bearings generally favour the waviness small tapered roller bearings, bearing noise is low in this category. Bearing raceways affects the sound of the machine as a whole.
