Worn journal finishing: On the premise of ensuring the design surface roughness, use the minimum processing amount to process, and then use the processed journal size and its deviation as a benchmark to prepare the bearing according to the original design matching performance.
Journal insert: Polish the worn journal and make another steel sleeve. Red Star Heavy Industry reminds users that the inner hole and journal of the steel sleeve should be an interference fit, and the outer diameter should be processed according to the original design size and tolerance. At the same time, it should be noted that the steel sleeve should be shrunk onto the journal.
Surfacing journal surface: Use manual arc welding to surfacing the journal surface, and then perform cutting processing to achieve the original designed journal size and deviation. And ensure that the eccentric shaft does not produce bending deformation. When repairing welding, attention should be paid to selecting the type of electrode, the minimum and best surfacing current, the diameter of the electrode should be as small as possible, and surfacing should be done symmetrically. Care must be taken to avoid local overheating during surfacing to prevent deformation. During processing, care should be taken to select a centering datum reasonably to maintain the running accuracy after assembly.
