| Abstract:In order to solve the problem of abnormal failure of the internal cage frequently occurred in the washing moving roller bearing of the enterprise paper machine for a period of time, this paper finds out the failure reason of the washing moving roller bearing 22216EK in this situation. There are four points: 1. Insufficient bearing lubrication; 2. Improper bearing assembly; 3. Impurities enter the bearing; 4. Bearing load is too large. Through targeted analysis of each cause and measurement of the actual position of the washing moving roller, the force analysis model of the washing moving roller is established to study the reasons for the bearing failure of the washing moving roller. The results show that during the operation of the paper machine, the excessive load of the washing moving roller is the main reason for the abnormal damage of the bearing 22216EK. By replacing the bearing of the washing roller to 22216CAK/W33 during the maintenance period of the paper machine, the abnormal failure of the washing roller bearing was effectively solved. This paper provides a valuable reference for the normal operation of the paper machine washing roller in the future. |
