Lead to needle roller bearing the main problem of the premature failure

Needle roller bearings failure for many reasons, all the influence factors of design and manufacturing process will be associated with the failure of bearing, analysis it is not easy to judge. In general, generally can be used from the two aspects of factors and internal factors considered and analyzed. Use factors mainly refers to install, use, maintenance, maintenance, repair and so on meets the technical requirements. Installation conditions is one of the primary factor of use factor, bearing is often caused by improper installation of a complete set of change the stress of bearing between various parts, needle roller bearings in the abnormal state run and early failure. According to the bearing installation, use, maintenance, maintenance of technical requirements, the operation of the bearing on the load, speed, temperature, vibration, noise and lubrication condition monitoring and inspection, found that abnormal immediately to find the reason, adjustment, so that it is back to normal. In addition, analyze the grease and the surrounding medium, the atmosphere quality inspection is also very important. 1. How to deal with the needle roller bearing temperature is too high ( 1) 。 ( 2) 。 Bright, light plate machine by hydraulic mechanical fault indicates the instrument temperature, bearing temperature signal relay action. ( 3) 。 The thermometer plate ( Inflating the thermometer) Black stitches overlap or more yellow and yellow needle. ( 4) 。 A needle roller bearing fault signal of temperature rise. 2. The causes of bearing high temperature phenomenon: ( 1) 。 It is possible that bearing cooling water, high temperature phenomenon. ( 2) 。 Is likely to be oil degradation of needle roller bearings, the oil itself will not clean the CPC degradation, or run. Such as moisture in the oil increase can cause the acidity of the oil, can reduce oil lubrication, the bearing shell eroded, causing the bearing temperature rise phenomenon.
