Rizhao slew bearings, Rizhao slewing bearings. 3. 'Generally, everyone feels that the industry is relatively noisy,
Slewing bearings' have not avoided this. Because it is mainly used in the industrial field, it will produce louder sounds during physical operation, so how can we minimize the noise?
' The rolling sound of the slewing bearing and its control method The rolling sound is the harsh metal friction sound that may occur in cylindrical roller slewing bearings in all situations. It mostly occurs in larger models of grease-lubricated slewing bearings. However, it is more likely to occur in greases whose base oil properties have deteriorated, and almost never occurs in oil lubrication. In addition, it is more likely to occur in winter. When subjected to pure radial load, it is likely to occur in situations where the radial clearance is large. Depending on the model size, it is likely to occur within a specific speed range, and it will occur continuously. It will appear intermittently again. Special processing methods for the outer ring raceway can prevent the occurrence of rolling sounds. If necessary, you can use this kind of slewing bearing, or appropriately reduce the radial clearance of the slewing bearing, use grease with excellent performance and improve the machine matching the slewing bearing. The rigidity of the parts.
' The rolling sound of the slewing bearing and its control method The rolling sound is a slippery and continuous sound made by the rolling elements rolling on the raceway surface when the slewing bearing is running. It is a sound that all rolling slewing bearings will make. A unique fundamental sound that occurs. The general slewing bearing sound is the sound of the raceway plus other sounds. The raceway sound of the ball slewing bearing is irregular, with a frequency above. Its main frequency does not change with the rotation speed, but its total sound pressure level increases with the acceleration of the rotation speed. For a slewing bearing with loud raceway noise, the sound pressure level of the raceway sound decreases as the viscosity increases. For a slewing bearing with small raceway noise, the sound pressure level changes from decrease to increased. The greater the rigidity of the slewing bearing, the lower the total sound pressure level of the raceway sound. If the radial clearance is too small, the total sound pressure level and main frequency of the raceway sound will increase sharply as the radial clearance decreases. Methods to control raceway sound include: selecting low-noise slewing bearings, that is, slewing bearings with very small waviness, and carefully selecting usage conditions. The sound of the rolling tracks often affects the noise of the entire machine. Reducing the sound of the rolling tracks can reduce the noise of the entire machine 3 :-- -Mr. Ding
