Factors affecting vibration and noise of 6320 bearing
Ring factor
When the deep groove ball bearings rotates, the rolling elements roll in the raceway and excite a smooth and continuous noise. This noise is usually called raceway sound. The raceway sound will directly increase the vibration and noise of the bearing. The source of this noise is the inherent vibration of the ring after being loaded. The vibration and noise of the bearing can be reduced by improving the roundness, waviness and other precision levels of the bearing ring channel.
When analyzing the surface accuracy of the ferrule, NSAR uses the advanced Taylor Hobson to analyze the roundness and waviness of the ferrule. Taylor Hobson can detect the waviness of only a few nanometers, thereby improving the product process for quality assurance engineers. Provides strong protection.
Steel ball factor
The vibration value and surface accuracy of the steel ball directly affect the generation of bearing vibration and noise. NSAR requires the steel balls produced by the steel ball manufacturer to have very low vibration values and good surface accuracy. For example, to improve the roundness and waviness requirements of the steel balls, observe the surface of the steel ball under a 100x microscope and there should be no scratches on the surface. Injuries, abrasions, gnaws and other defects. In order to achieve the purpose of reducing bearing vibration and noise.
Cage of 6320 bearings
The free vibration of the cage and its collision with the rolling elements during the rotation of the bearing will emit a noise, which is often called cage sound. The sound of the cage will directly increase the vibration and noise of the bearing. It can be improved by improving the manufacturing accuracy of the cage and optimizing the reasonable clearance and cage movement. The manufacturers of the cages used by NSAR have advanced production processes and extremely high manufacturing levels. After dozens of experiments on the amount of movement of the cage, an ideal value was obtained for the amount of movement of the cage. Provides help in reducing vibration and noise of bearings.
Cleanliness factor
Poor bearing cleaning will directly increase the vibration and noise of the bearing. Therefore, it is particularly important to actively use advanced cleaning technology to effectively and thoroughly clean spare parts and assembled products to improve the cleanliness of bearings. NSAR uses advanced gas-phase cleaning machines to effectively clean bearing parts; in terms of product cleaning after assembly, the cleaning equipment adopts an ultrasonic first, then spray process, in which the spray cleaning adopts a scientific multi-stage spray process. The cleanliness of the bearing is greatly improved, thereby reducing the vibration and noise of the bearing.
Grease factor
Special grease for bearings plays a key role in reducing vibration and noise of bearings. Good grease can not only extend the life of the bearing, but also reduce the vibration of the bearing and reduce the noise of the bearing. Especially for motors that have special requirements for noise, the selection of bearing grease is particularly important. NSAR can select different greases for customers according to their different usage requirements, so that the vibration and noise of the bearings can fully meet the customers’ special usage requirements.
