WZ1004-NN型喷射式真空回潮机在生产过程中,其烟箱传动系统经常出现轴承过度磨损、传动轴磨损或折断等故障,导致烟箱不能及时输送,影响了生产的连续性。文章针对真空回潮机频繁出现此故障,通过分析,发现其烟箱传动系统输出主轴采用滑动轴承支撑,该类轴承没有轴向定位,不能在线加油润滑,缺油后处于干摩擦状态,轴承与轴相互摩擦,多方面造成故障。通过改进传动轴的支撑类型,把滑动轴承改为滚动轴承,增加轴的轴向定位,改善轴承的润滑状态,加工相应尺寸的传动轴,使问题得到解决。
WZ1004-NN jet vacuum machine in the production process, the smoke box drive system often bearing excessive wear and tear, shaft wear or broken fault, resulting in timely delivery of smoke can not affect the continuity of production. The article for the vacuum recycle machine frequent this failure, through the analysis and found that the smoke box drive system output shaft with sliding bearing support, this type of bearing without axial positioning, can not be online lubrication, lack of oil in a dry friction state, bearing and shaft Mutual friction, causing many problems. The problem can be solved by improving the support type of the transmission shaft, changing the sliding bearing to the rolling bearing, increasing the axial positioning of the shaft, improving the lubrication state of the bearing, and processing the correspondingly-sized transmission shaft.
