GE-ES Radial Spherical Plain Bearings

GE-ES Radial Spherical Plain Bearings Features

The temperature of spherical joint bearing is very important. Long-term high temperature indicates that the bearing is in abnormal condition.High temperature is also harmful to bearing lubricants.Sometimes bearing overheating can be attributed to the bearing lubricant.If the bearing temperature for a long time even the transfer of more than 125 ℃ lower bearing life.A cause of insufficient or excessive lubrication; a lubricant.It contains impurities, excessive load, bearing failure ring, insufficient clearance, and high friction caused by oil seal, etc.Therefore, continuous monitoring of bearing temperature is necessary, whether it is measuring the bearing itself or other important parts.If the operating conditions remain unchanged, any temperature change may indicate that a fault has occurred.When the bearing is running under load, due to the increase of the contact stress between the rolling body and the raceway contact surface, the operating temperature will rise, the performance of the lubricant will deteriorate relatively, and the limit speed of the bearing will decrease correspondingly.For spherical joint bearing bearing joint load, due to the increase in the number of rolling body bearing load, increase in friction resistance, increase in calorific value, poor lubrication and cooling conditions, and increase in the force on the holder, it must be based on the type of bearing and the size of the load Angle.If the ultimate speed and speed of the selected NTN bearing cannot meet the use requirements, some improvement technical measures can be adopted to improve it, so as to achieve more satisfactory requirements.If the bearing tolerance level is increased;Appropriately increase the clearance;Switching to special materials and improving the cage structure,Change lubrication methods, such as oil and gas, oil mist and spray lubrication, improve cooling conditions.

Re-adjust the fit tightness between the shaft and the inner ring during processing, and the clearance after bearing replacement is appropriate.Bearing internal clearance is too small or parts design and manufacturing accuracy is not good, are the main reason for the high running temperature of the bearing, generally in the design of the bearing seat with fixed sleeve bearing cone hole with inner ring, but also easy to cause problems due to the negligence of installation procedures.The internal clearance of the bearing is too small.The rapid increase of running temperature is due to the loose fit between the inner ring taper hole and the set sleeve, which is damaged by the short-term failure due to the loose fit surface.Adopt the method that will bear the ring clearance of rotating load to match, the shaft should use hard material, the surface is machined meticulously, add sufficient lubricant, utmost ground prevents the damage that slip causes.
