Vibration and temperature for KOYO outer spherical bearing damage prevention methods

In KOYO bearings used in the process, to say the vibration and temperature on the influence of the bearing is very big, let's take a look at the influence of the bearing vibration of external spherical bearing. Vibration of the bearing damage is quite sensitive, peeling, indentation, rust, crack and wear will be reflected in the bearing vibration measuring. So, through the use of special bearing vibration tester ( Frequency analyzer, etc. ) Can measure the size of the vibration, through frequency points cannot deduce the abnormal situation. Measured value because of outer spherical bearing or sensor installation position and different using conditions, thus requiring prior to each machine is analyzed by the measured value of the determined after judgment standard. With high temperature often said bearing is in abnormal situation. High temperature also harmful to the bearing lubricant. Sometimes overheated bearings can be classified to the bearing lubricant. If the bearing temperature for a long time even the transfer of more than 125 ℃ lower bearing life. The causes of high temperature bearing include: lubrication inadequate or excessive lubrication, the lubricant. Contains impurities, heavy load, outer spherical bearing damage, the gap is insufficient, high friction and oil seal and so on. So the continuity of bearing temperature monitoring is necessary, whether measured bearing itself or other important parts. If it is on the basis of the operating conditions, the temperature change of any fault has occurred. Cause the cause of early damage of the KOYO bearings are various, sometimes may be integrated. If outer spherical bearing selection, correct installation properly in place, and choose the right lubricant lubrication way, keep maintenance and preventive measures, the bearing can be normal work for a long time. 1. Assembly improper installation use brute force, is the main cause of deformation. Installation does not reach the designated position, was the cause of the defect. Suggestion: select the appropriate or professional bearing installation tools, installed with a special instrument to detect. 2. Pollution damage of pollution can also cause premature KOYO bearing damage, pollution refers to water, dust, metal scraps into the bearing inside. Can lead to bearing rust, surface wear, abrasion and sag. Suggestion: regular inspection seal, bearing of to use cleaning; Strengthen KOYO bearing sealing device. 3. Bad lubrication failure to refill lubricant or lubricating oil; Lubricant or lubricating oil filling in place; Lubricant or improper lubricant selection; Lubrication method is not correct, and so on, lead to serious KOYO bearing components abrasion or deformation. Advice: choose the right lubricant or lubricating oil, use the correct lubrication way of filling, added lubricants on a regular basis. 4. Current and eccentric bearing rotates the electricity may result in a groove or notch, outside the spherical bearing static, electrical grounding improper operation will lead to a slight burns, eccentric or excessive load operation may result in geometrical stress concentration or surface spalling. Suggestion: before foreign outside the spherical bearing parts welding current can be reduced or avoided through proper grounding connection by bearing, precision machining KOYO bearing seat and over the shoulder.
