207 bearing: whirlpool washing machines bearing is broken how to determine

Will choose the tolerance requirements of annotation on the diagram, as shown in figure, figure bearing degradation in the first phase of the vibration signal characteristics of the first stage, the bearing expiration period, as shown. The table shows: the inclusion content of bearing pads is less, because of lack of clear standards requirements ( The supply and demand both sides talks things over to determine) And the level of evaluation for reference only; Gasket microstructure ( See figure to comply with relevant standards. In order to feed and discharge of oil, in the split babbitt was cut off part of the bearing, it formed with the circular boundary and at the end of bearing bush inward extension of oil tank. Cage abnormal loading, causing wear failure are the major factors of lubricant or the lack of lubricant, lubrication method is wrong, there are internal grinding grain into the bearing, heavy load, etc. And with the use of frequent, inevitably leads to series of wear problem, another some machining unit adopts the set set of measures, also use this method just for the motor end cover is used without spare parts. Under normal circumstances, the spindle should be rolling bearing, particularly for the vertical spindle, only when the main shaft in horizontal, and processing the workpiece surface roughness value is small, sliding bearing is used. （ iii） Methods: synthetic two sets of assembly, assembly precision, rolling body overload the indentation is called a brinell indentation, the indentation will lead to bearing failure, such as; Bearing down inappropriate or installation, etc. Splash lubrication and oil bath lubrication of comprehensive technical and economic index is low, should use or not use less as far as possible, whether can for unlimited use of grease, affirmative answer is not possible. Go outer shell holes and bearing outside diameter with too loose, Commonly known as the 'outer') Because the shell aperture and the choice of bearing outside diameter fit is too loose ( The public number: pump pipe home) To make them between sliding surfaces. Publishing monographs, textbooks, moreover, lubrication method, cost control, equipment level, before first use or their situation such as the problems to implement. Using grease lubrication, should choose without impurities, antioxidant, antirust, superior performance, such as extreme pressure grease, grease filling quantity of bearing and the bearing box volume % - %, unfavorable and overmuch. Says below encountered in the process of debugging in production of several typical cases, respectively for design, installation, lubrication, assembling the specific problems of the analysis summary, for your reference.
