Repair the three aspects of outer spherical bearing

Outer spherical bearing used in the process of failure, should from what respect to start, take a look at below: 1, the maintenance of bearing temperature: usually the temperature of the outer spherical bearing as operation began to rise slowly, 1 to 2 hours to reach steady state. The normal temperature of bearing for machine and different heat capacity, heat dissipating capacity, rotational speed and load. If the lubrication, installation is not appropriate, the bearing temperature will go up sharply, there will be unusually high temperature, then must stop and take the necessary precautions. 2, overhaul of bearing lubricant, lubrication of the bearing and the fatigue life of friction, wear, temperature rise, vibration, etc have important influence, not the normal lubrication, bearing cannot work. Analyzes the damage reasons of bearing show that about 40% of the bearing damage is related to poor lubrication, so good lubrication of the bearing is an effective measure to reduce the bearing friction and wear. 3, maintenance of bearing vibration, the vibration of the bearing of the bearing failure effect is obvious, for example: peeling, indentation, rust, crack and wear will be reflected in the bearing vibration testing, so through the use of special bearing vibration measurement device ( Frequency analyzer and vibration meter, etc. ) Can measure the size of the vibration, through frequency distribution can be deduced, under the condition of abnormal vibration measured values due to the use of the bearing condition or sensor installation position and different, so need prior to each machine after the analysis and comparison the measured value of decision criteria to determine.
