GAC-T Angular Contact Spherical Plain Bearing Features

The internal failure factors of spherical plain bearing mainly refer to the three factors that determine the bearing quality, such as structural design, manufacturing technology and material quality.The main reason of fracture failure of integral eccentric bearing is defect and overload.When the applied load exceeds the material strength limit, the fracture of the part is called overload fracture.The main reason of overload is the sudden failure of main engine or improper installation.Bearing parts of the micro-cracks, shrinkage, bubbles, large foreign debris, overheating tissue and local burns and other defects in impact overload or severe vibration will also cause fracture at the defect, known as defect fracture.It should be pointed out that in the manufacturing process of bearings, the re-inspection of raw materials into the factory, the quality control of forging and heat treatment, and the control of the processing process, the above defects can be correctly analyzed through instruments.But generally speaking, most of the bearing fracture failures are overload failures.The main task of spherical joint bearing failure analysis is to find out the main factors causing the failure of the bearing according to a large number of background materials, analysis data and failure forms, so as to put forward targeted improvement measures, extend the service period of the overall eccentric bearing and avoid sudden early failure of the bearing.Bearing in the work, due to the influence of external or internal factors, so that the original fit clearance change, precision reduction, and even cause bite dead is called clearance change failure.External factors such as excessive interference, improper installation, expansion caused by temperature rise, instantaneous overload, internal factors such as residual austenite and residual stress in an unstable state are the main reasons for the failure of clearance change.If the bearing is damaged, check whether the ball bearing or bearing bush of the ball bearing is damaged.Repair or replace if damaged.Lubricating oil with impurities, too dirty, oil ring stuck or wrong brand.Should change the oil, find out the cause of stuck repair, oil viscosity should be replaced when too large.Oil shortage in bearing chamber.Fill 2/3 chamber with grease or add lubricant to standard oil line.The lubricating grease in the rolling bearing is too blocked, and the temperature of the lubricating oil in the integral eccentric bearing is too low or too high.Excessive grease should be removed from the rolling bearings or the grease inside the oil chamber should be filled.Bearing and shaft, bearing and end cover with too loose or too tight, too tight will make the overall eccentric bearing deformation.If the bearing and shaft are too loose, the shaft neck can be painted with metal paint. If it is too tight, it can be reprocessed.The bearing and the end cover cooperate too loose to set the end cover tight, reprocess if too tight.The two end covers or bearing covers of the motor are not properly assembled, and are usually not parallel, resulting in the overall eccentric bearing is not in the correct position.Install both end caps or bearing caps with flat ends and tighten the bolts.Belt is too tight, too loose or coupling assembly is bad.Adjust the belt tightness;Alignment coupling.The wrong type of bearing was changed during maintenance.Replace the correct type of bearing as soon as possible.
