The causes and precautions in the TIMKEN bearing temperature

TIMKEN bearing when applying when installation should pay attention to the issues, work together as far as possible through the axis of the bearing, this requires the screws evenly symmetry and smooth, by spherical or parallel to the axis force application. Wire should be smooth and uniform, the size of the unfavorable impact, this request can use hydraulic or use steady pull or pressure tool, it had to use hammer, also want to through soft without exfoliation metals such as copper sleeve to buffer, tapping force as gently as possible. It is best to use copper or copper hammer hammer. Avoid by applying pressure roller, which requires the inner ring (installation Axial circle) When applying pressure through the inner ring and outer ring installation) Through the outer power works. 1. TIMKEN bearing temperature rise should be how to deal with: when the TIMKEN bearing temperature, first determines whether the wrong operation, such as really rise, should do the following treatment: ( 1) 。 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. ( 2) 。 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. ( 3) 。 Check for different bearing, bearing and testing degrees whether there are abnormal. ( 4) 。 Should be to check if the governor oil pressure, oil pressure is low can lead to cooling water hydraulic valve closed. ( 5) 。 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. First of all, let's take a look at the cause of the TIMKEN bearing temperature: ( 1) 。 Is likely to be oil degradation of TIMKEN bearing, 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. ( 2) 。 May be because the TIMKEN bearing caused by cooling water. 3. The phenomenon of TIMKEN bearing temperature rise: ( 1) 。 Bearing temperature fault signal. ( 2) 。 The thermometer plate ( Inflating the thermometer) Black stitches overlap or more yellow and yellow needle. ( 3) 。 Bright, light plate machine by hydraulic mechanical fault indicates the instrument temperature, bearing temperature signal relay action. ( 4) 。 Has the alarm bell rang.
