GEGZ-ES Radial Spherical Plain Bearings

GEGZ-ES Radial Spherical Plain Bearings Features

The limit speed of spherical plain bearing is the maximum allowable speed under certain load and lubrication conditions, which is related to the bearing type, size, load size and direction, type of lubricant and lubrication mode, clearance, cage structure, cooling conditions and many other factors.Factors affecting the limit speed, load size, load type and direction, lubricant and lubrication.The limit speed of the bearing can also be improved by improving the manufacturing accuracy of the bearing, properly increasing the clearance of the bearing and adopting the special material and structure of the cage.Spherical joint bearing temperature is too high, the quality of the lubricating oil does not meet the requirements or deterioration, the viscosity of the lubricating oil is too high, the assembly is too tight, one-way bearing assembly is too tight, bearing seat ring in the shaft or shell rotation, the load is too large, bearing cage or rolling body fragmentation, etc..The bearing is allowed to have a slight running noise during operation. If the noise is too loud or there is abnormal noise or crash sound, it indicates that the bearing is faulty.The noise of the bearing is caused by the wear of the inner and outer rings of the bearing.Due to this kind of wear and tear, the matching relationship between the bearing and the housing and the one-way bearing and the shaft is damaged, which results in the axis deviating from the correct position and generates abnormal sound when the shaft moves at high speed.When the bearing fatigue, its surface metal peeling, will also make the bearing radial clearance increase abnormal sound.In addition, bearing lubrication is insufficient, the formation of dry friction, and bearing crushing will produce abnormal sound.Bearing wear loose, loose cage damage, will also produce abnormal sound bearing damage.When the bearing is disassembled for inspection, the failure and damage reason of the one-way bearing can be judged according to the damage condition of the bearing.Pressure constant preload is applied using a helical spring, a saucer spring, given the proper preparation method of bearing.In use, even if the bearing changes in relative position, the method of preloading.
