摘要:为了解决某企业纸机洗涤动辊轴承在一段时间内频繁出现内部保持架异常失效问题，本文针对此情况找出洗涤动辊轴承22216EK失效原因存在4点：①轴承润滑不足；②轴承装配不当；③杂质进入轴承；④轴承负载过大。通过有针对性地逐条原因分析，以及对洗涤动辊实际位置测量，建立洗涤动辊受力分析模型，研究洗涤动辊轴承失效原因。结果表明，纸机在运行期间，洗涤动辊负载过大是轴承22216EK异常损坏的主要原因。通过在纸机停机检修期间，更换洗涤辊轴承为22316CAK/W33后，洗涤动辊轴承异常失效问题得到有效解决。

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 machines for a period of time， this paper finded out the failure reasons of the washing moving roller bearing 22216EK in this situation. There were four points： ① insufficient bearing lubrication， ② improper bearing assembly， ③ impurities enter the bearing， ④ bearing load was 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 was established to study the reasons for the bearing failure of the washing moving roller. The results showed that during the operation of the paper machine， the excessive load of the washing moving roller was 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.
