After using the belt drive spindle machining center for a long time, it is found that the spindle box belt has abnormal noise, whether it is in forward or reverse rotation, there will be some noise. According to many years of experience, most of them are belt problems. As long as we start from the belt of the main shaft, we can find out the key problem of making noise.
The belt tension of the spindle connected to the servo motor is too high
The tension of the belt connecting the main shaft to the servo motor should not be too tight. If it is too tight, it will easily lead to the wear of the belt, slip and make abnormal noise,
The belt tension between the spindle and the servo motor is too low
The tension of the belt connecting the spindle to the servo motor should not be too low. If the tension is too low, it will appear that the belt connecting the spindle to the servo motor is too loose. In this way, it is easy to cause slipping and make abnormal noise during heavy cutting.
The belt connecting the spindle 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, which is also one of the reasons for the abnormal noise of the belt. Therefore, the better quality of the drive belt to use a longer time, poor quality drive belt use time is shorter.
The tooth profile of the drive belt does not match that of the servo motor and the spindle
As the drive belt of the machining center is used for a long time, it will cause some wear, so many customers purchase the drive belt to replace it in order to save the cost. After replacement, it is found that the tooth shape of the drive belt is not consistent with that of the servo motor and the spindle, which will cause abnormal noise during use. It is suggested that customers should pay attention to whether the model of the purchased drive belt is the same as that of the removed worn belt. If different types of drive belts are used persistently, the abnormal noise of the belt in the transmission process will be caused, and even the gear wear of servo motor and spindle will be caused, resulting in serious consequences.
