The formation mechanism of grinding badness layer of bearings working surface

Formation mechanism of grinding badness layer of bearings working surface, the main factors influencing the grinding metamorphic layer is a function of grinding and grinding force. Let's to analyze the causes of bearing heating, generated by the phenomenon, and then find out the way to solve and processing. Below is simple said the cause of the bearing temperature is too high and the solution. The phenomenon of bearing temperature ( 1) ( 2) Bright light plate, machine by hydraulic mechanical fault, indicates the instrument temperature, bearing temperature signal relay action. ( 3) , thermometer ( Inflating the thermometer) Black stitches overlap or more yellow and yellow needle. ( 4) The fault signal, a bearing temperature rise. The cause of the bearing temperature ( 1) , bearing cooling water. ( 2) , degradation of oil, the oil itself is not clean or run medium oil degradation, such as moisture in the oil increase can cause the acidity of the oil, can reduce oil lubrication, the bearing shell was corrosion, cause temperature rise of bearing. The processing of bearing temperature, as the bearing temperature rise first determines whether the misoperation, as did rise, should do the following treatment: ( 1) , check the cooling water pressure, water flow and pipeline system is normal. If water is likely to be lower filter blockage, cannot be handled in a timely manner, to stop treatment, when confirm can work, then put into use. ( 2) Low, should be to check if the governor oil pressure, oil pressure may lead to water hydraulic valve closed. ( 3) , check the bearing for different sounds and detect bearings degrees whether there are abnormal. ( 4) , take oil whether there is a change of color, sample observation and test to see whether metamorphism. If confirm the degradation new oil should be replaced downtime. ( 5) , check the oil standard oil level is normal, if abnormal, check that the sump oil discharge valve is shut. If the matter, should fill oil, if is the sealant mat permeability oil, should stop processing. When we are in the use of miniature bearing, if it is found that the temperature is very high, is to stop the equipment running, and find out its reason, and provide solution for processing according to the above, but may be due to the reason of bearing heating is different, so the solution is also different, so still have to treat, particular case is particular completed with the help of the technical staff.
