Several aspects of the service life of universal joint bearings

In some special operating conditions, can obtain a longer than traditional computing by universal joint bearing life, especially in the case of light load. These special operating conditions is, when the rolling surface ( Track and rolling piece) Can be separated by a lubricating oil film effectively and the surface of the limit of pollutants may cause damage. In fact, under ideal conditions, the so-called permanent bearing life is possible. ( 1) Bad lubrication gimbal bearings used lubricating oil, Or grease) Have some working temperature, when the temperature is too high will deteriorate, thereby losing lubrication, the bearing damage due to high temperature. In addition, lubricating oil ( Or grease) Itself in the operation of the poor quality of a material or gas ( Fat) Not in time, will also cause bearing temperature or produce different sound. ( 2) In the rotor rotor imbalance in general, before we install it will go into action, the static balance, therefore, universal joint bearing is no problem. But some of the rotor in the process of running due to medium corrosion or wear and tear of solid impurities, or bent shaft, will lead to unbalanced centrifugal force, so that the bearing heating, vibration, roll the serious wear and tear, until the destruction. ( 3) Check replacement is not universal joint bearing during operation in time, regular inspection by the regulation, if fever, noise, vibration, etc. , to stop in time to find the reason, eliminate the fault, bearing such as found serious fatigue spalling, pit, crack, hardness of the oxidation corrosion, wear and tear down to HRC < 60, or when there is too much noise can't adjust, should be replaced in a timely manner. If the check, change not in time, can cause serious damage of the rotor of bearing and even to affect the normal production. In addition, improper bearing removal, the equipment anchor bolt loosening caused by vibration, can also lead to bearing raceway and rolling body produce indentation, cracking of bearing inner and outer ring.
