Analyse des causes de défaillance et d'endommagement des pièces de roulement des bobineuses automatiques

Bearing is an important functional component in automatic winding machine. It is mainly used in the spindle system, the lineup system and the ejector tailstock. It is utilized more frequently, so its failure rate is relatively high, but of course normal overhaul and maintenance is important. Usually, during the maintenance process, the failure of the bearing and the cause of the damage can be determined according to the damage of the bearing.

The failure of automatic winding machine is mainly the following cases.

1. Metal wear of the bearings of the automatic winding machine

The bearings of the automatic winding machine during operation can lead to metal fatigue conditions if the load is too great. Many times it is caused by the eccentricity of the mold of the winding machine. In addition, if the bearings are not installed correctly and the shaft is bent when the automatic winding machine is assembled, these failures can also occur. Bearing raceways running for a long time will affect the running accuracy of the bearing, which will lead to vibration and noise generation of the equipment.

2. Automatic winding machine bearing burns and discoloration

Most of the reasons for bearing burns in automatic winding machines are due to insufficient lubrication and the quality of the lubricant is not up to standard. In addition, the bearing assembly is too tight can also cause this situation, and the unreasonable distance between the thimble of the automatic winding machine can also cause the bearing to burn.

3. Cracks appear in the bearings of the automatic winding machine

The cause of this condition may be the deformation of part of the bearing due to the bearing being too tight. In addition, when the bearings are rotated at high speed, the wear and tear of the bearing fixings of the winding machine may also cause cracks.

There are many mechanism components of the automatic winding machine, and various failures may occur during use. When these problems occur, it is important to find the cause of the failure first and then take some measures to avoid these failures.
