负载异常一般是绕线机使用单位超出设备使用范围,私自加大绕线负载所造成的SKF轴承损坏,处理方法:将绕线负载控制在设备答应值内,对损坏的SKF轴承及时更换,清洗有关零件,使用干净的润滑剂。
Load exception is usually winding machine units beyond the scope of equipment use, without permission increased winding SKF bearing damage caused by load, treatment methods: winding load control devices promise value within the SKF bearings replaced in a timely manner to damage, wash the parts, use clean lubricant.
1、尽可能采用专用仪器测量法;
1, as far as possible the use of special instruments and measurements;
2、采用手推法测量要求测量者有较高的测量技能,此法测量误差较大,尤其是游隙处于边缘状态时,容易引起误差,此时,应以仪器测量为准;
2, the use of hand-push method for measuring the requirements of measuring higher measurement skills, this method of measurement error is large, especially when clearance of marginalized, prone to error, in which case the instruments shall prevail;
3、塞尺测量时,应按标准的规定操作,不得使用滚子从塞尺上滚压过去的方法测量;
3, the examiner measured should be standard operation, rolling past on the roller from the examiner shall be used methods of measurement;
4、测量过程中,应保证球落入沟底,闭型轴承在封闭前测量,采用有荷仪器时,测值还应减去载荷引起的游隙增加量;
4, in the measurement process, should ensure that the ball fell into the ditch, closed type bearings in front of the closed measurements, when a Dutch instrument, measuring value by subtracting the load increase in clearance caused by volume;
5、对于多列SKF轴承,要求每列游隙合格,取各列游隙的算术平均值作为轴承的径向游隙。
5, for SKF bearings requiring clearance qualified in each column, taking the arithmetic average value as the clearance of radial clearance of bearings.
使用单位保养轨制不健全,设备缺乏必要的按期保养、润滑所造成的故障,这类故障是绕线机故障的主要原因,轴承泛起异常的温度升高,润滑剂严峻泄漏,SKF轴承变色等等题目,处理方法:建立良好的设备保养轨制,专人按期保养设备,对润滑部件按期加油检查,及时增补润滑剂并选择选择适当的润滑剂,及时的调整外壳的挡肩位置,并清除轴衬四周的异物。
Using units maintenance rail system does not sound, device lack necessary of periodical maintenance, and lubrication by caused of fault, this class fault is winding machine fault of main causes, bearing formed the exception of temperature rise, lubricant serious leak, SKF bearing discoloration and so on topics, processing method: established good of device maintenance rail system, hand periodical maintenance device, on lubrication parts periodical refueling check, timely additions lubricant and select select appropriate of lubricant, timely of adjustment shell of retaining shoulder location, and clear axis lining around of foreign body.
