Load exception is usually winding machine units beyond the scope of equipment use, to increase the linear bearing winding damage caused by load, treatment methods: winding load control devices promise value within the INA bearing damage, timely replacement, cleaning the parts, use clean lubricant.
1, as far as possible using special instruments measurement method;
2, by measuring the skill of manual measurement requirements of measuring higher, this method of measurement error, especially when clearance of marginalized, easy to cause the error, at this time, should be the instrument measured;
3, feeler, should be operated according to the provisions of the standard, shall not be used on the roller from the examiner rolling measurement methods of the past;
4, the measurement process, should ensure that the ball fell into the ditch, closed type bearing in front of the closed measurements, using a Dutch instrument, measuring value should be less loading induced increase in clearance;
6, for the multiple linear bearings, the requirements of qualified each clearance, clearance from each column of the arithmetic mean as the bearing radial clearance.
Use the unit maintenance system is not perfect, the fault equipment maintenance schedule, lack of lubrication caused, this kind of fault is the main reason for the failure of wire winding machine, bearing appearing abnormal temperature rise, serious leakage of INA bearing lubricant, color and so on, processing method: build the equipment maintenance good system, special schedule maintenance of equipment of lubricating parts, regular refueling check, timely supplement lubricant and select appropriate lubricant, shoulder position adjustment housing timely, foreign body and remove the bushes around.
