The vibration of the bearing to your motor bearing noise, A)

For examination and assessment of motor bearing vibration noise, it is one of the key index of comprehensive quality of the bearing. Bearing noise is not only directly harm the performance of the product, and excessive noise will continue to cause harm to the bearing. Bearing noise caused by the principle of rolling bearing itself does not cause noise, bearing noise is the bearing capacity in the whole operation process of a kind of noise caused by vibration and impact each other. The ductility of bearing parts strong vibration and the ratio of the vibration of solid, sound in the audio category by the solid gas for bearing vibration caused by noise. Generally think of 'bearing noise', is actually the bearing immediately or indirectly caused the vibration noise of utility and the surrounding structure, which is why in many cases, noise problems can be regarded as involving bearing using vibration problem. The types of bearing noise of rolling bearing vibration is the root causes of bearing noise, different bearing noise from different kinds of bearing vibration. As the vibration of the bearing, bearing noise cause principle is also very complex. According to the bearing characteristics caused by noise, can be divided into the following categories: the bearing noise by the structure of the motor bearing form, size and other factors caused by noise: on the basis of the noise, such as the elastic deformation of bearing, rolling body, caused by the clearance, and maintaining the aircraft noise. Cause the noise of the bearing surface of utility: such as bearing inner and outer ring, concentricity, wavy grain on the surface of the steel ball work degrees, such as surface roughness and disadvantages caused by the noise. A lot of experimental research show that deep groove ball bearing outer, inner hole and the quality of the surface of the steel ball bearing noise harm is 1:3:10, steel ball surface quality of deep groove ball bearing noise harm is big. Due to friction with RunHua noise: friction and RunHua on rolling bearing noise has great damage, small friction, RunHua situation is good, bearing caused by noise. Work standard of noise: motor bearing load, speed ratio, installation of mutual cooperation situation immediate hazard bearing noise cause, the higher the speed ratio of the bearing is, the greater the load, the bearing caused by noise. In addition, related studies have shown that 50% of the bearing noise is caused by poor installation. The above is the content of the author to share today, want to learn more bearing small knowledge, pay attention to the bearing's official website.
