SEMRI bearing rolling road sound and its control method rolling road sound is when the operation of the one-way bearing, the rolling body in the roll road surface rolling and making a slippery continuous sound, is unique to all rolling bearings are the basic sound. The general bearing sound is the sound of the rolling and other sounds. Ball bearing rolling road sound is irregular the, frequency 1000Hz, the frequency rate does not change with the speed, but the overall sound pressure level with the acceleration of the speed. Rolling road sound of the bearing, the rolling road sound of sound pressure level decreases with the increase of the viscosity of the; and rolling road sound small bearing, the sound pressure level in the viscosity increases to more than about 20mm2/s, by reducing and turn to increase. The more rigid bearing raceway, lower the total sound pressure level. Such as the radial clearance is too small, the raceway total sound pressure level and frequency with reduced radial clearance and increased sharply. The method of controlling the sound of the rolling path is: the selection of low noise bearing that is very small in the bearing, carefully chosen to use conditions. The noise of the whole machine is often affected by the sound of the rolling, and the noise of the whole machine can be reduced.

Rolling bearings are precision components, the use of it is also required to be careful. Regardless of how high performance of the bearing, if used improperly, it will not be expected to high performance. The use of SEMRI bearing notes are as follows:

1, carefully use

Bearing a strong impact in the use, will produce scars and indentation, become the cause of the accident. In serious cases, it will crack, fracture, so we must pay attention to.

2. Keep the bearings and the surrounding clean.

Even if the eye can not see the small dust, but also to bring bad influence to the bearing. So, to keep the surrounding clean, so that dust does not cause the intrusion bearing.

3, using appropriate operating tools

To avoid the use of existing tools to replace, must use appropriate tools.

4, to pay attention to the corrosion of bearing

When operating the SEMRI bearing, the sweat on the hand will become the cause of rust. To pay attention to the use of clean hands, preferably with gloves.

The impact sound of the rolling body and its control method of the ball bearing or cylindrical roller bearing in the pure radial load is smaller, the rolling body is in the non load region, the impact of the rolling body or the rolling way and the noise. But as the speed increases, the noise will disappear. The rolling body impact sound control method are: appropriate reduction of radial clearance, reasonable structure, a material compliance to keep the frame of the one-way bearing.
