After using a machining center with a belt-driven spindle for a long time, it is found that the spindle box belt has abnormal noises, whether it is forward or reverse rotation, there will be some noises.
According to the editor's many years of experience, most of the problems are belts. As long as we start with the belt of the drive spindle, we can definitely find out the key problem of the noise.
The editor will introduce some problems that will affect the sound of the belt.
- The belt tension of the spindle connected to the servo motor is too high: the belt tension of the spindle connected to the servo motor should not be too tight. Too tight will easily cause the belt to wear, slip, and make abnormal noises.
- The belt tension of the spindle connected to the servo motor is too low: the tension of the belt connected to the servo motor of the spindle should not be too low. If the tension is too low, the belt of the spindle connected to the servo motor is too loose, which will easily cause slippage during heavy cutting. The sound.
- The belt of the spindle connected to the servo motor is damaged: In general, the machining center has been used for a long time, and it is inevitable that there will be some defects, such as the transmission belt, which will wear after a long time. This is one of the reasons for the abnormal noise of the belt. Therefore, a better quality transmission belt will last longer, and a lower quality transmission belt will last longer.
- The tooth profile of the transmission belt does not match the tooth profile of the servo motor and the spindle: Because the transmission belt of the machining center will be worn for a long time, many customers buy the transmission belt by themselves in order to save costs. After replacement, they find the transmission belt The tooth profile is inconsistent with the tooth profile of the servo motor and the spindle, which will cause abnormal noise during use. Customers are advised to pay attention to whether the purchased drive belt is the same model as the worn out belt when purchasing a drive belt. If a different model of drive belt is used consistently, it will cause the belt to make abnormal noises during transmission, or even cause The gears of the servo motor and the main shaft are worn, causing serious consequences.
