GEZ-ES Radial Spherical Plain Bearings Features

In spherical plain bearings, seals are also very important, if there is a problem in the sealing part of the bearing will cause great impact, such as irregular shape, lack of meat, micro cracks and other defects of seals are not allowed.Bearing sealing test is in the assembly of the cylinder seal and its joints after the assembly and work reliability assessment.Such as cylinder cylinder sealing and connection, cylinder piston moving, static seals and sealing conditions.Bearing sealing test pressure is very big, especially for the pressure test without rod cavity, if there is no tool to bear, by no rod cavity pressure test and through the piston acting on the piston rod, if only by the connection of the cylinder head to bear is absolutely not.Therefore, usually this kind of pressure test is carefully assembled after the cylinder, before entering the final assembly machine debugging stage.When the interference of bearing and bearing diameter or bearing seat hole is small, the assembly method is usually adopted.The simplest method is to use the copper bar and hand hammer, in a certain order of symmetry to knock the bearing with interference with the seat ring, so that the bearing smoothly pressed.Additional, the casing that also can use soft metal to make borrows hammer drive or press machine to press.Improper operation may deform and crack the seat ring, or hammer the seat ring without interference fit, which may cause indentation of the raceway and rolling body or indirectly damage the bearing.Improper temperature control during assembly. If the interference between bearing and axle diameter is large, the bearing is usually assembled by hot loading method.The bearing in cans containing oil, engine oil barrels outside with hot water or flame heating, heating process requirement of the oil temperature control at 80 ℃ ~ 90 ℃, generally will not exceed 100 ℃.The bearing is heated and the package is quickly removed from the journal.If the heating temperature is too high due to improper temperature control, the bearing will be tempered and the hardness will be reduced, and the bearing will be easy to wear, peel, or even crack during operation.The clearance of rolling bearing is divided into radial clearance and axial clearance, whose function is to ensure the normal operation and lubrication of the rolling body as well as to compensate the thermal elongation.For bearings with adjustable clearance, the axial clearance and radial clearance are in direct proportion to each other, so as long as the axial clearance is adjusted, the required radial clearance can be obtained. However, they are generally used in pairs, and only one bearing's axial clearance needs to be adjusted.
