Can the contact surface of a turbine semi-circular bearing shell be a point line?
Thread Content
Is it reasonable to inspect a line about 1 centimeter wide on the semi-circular bearing shell of the turbine today?
Come and learn* about sofas. :)
In my opinion, there should be an oil film between the semi-circular tile and the shaft for protection, so a situation like the one you described should not occur.
Is this 1-centimeter contact line axial, or is it a line along the circumferential direction? If it is an axial shaft, of course the larger the contact surface, the better; however, it is necessary to measure the side clearance of the bearing shell and keep it within the range specified in the factory data ； If it’s a line in the circumferential direction, then we need to check whether there is a problem with the quality of the wafer.
Abnormal; the contact area should be at least 65–70% or more
Normally, the contact area should be over 60; the main issue is that the gap between the tiles is insufficient, which results in inadequate grinding
Whether you go on top of the tiles or underneath them, it would be good to have photos
It needs to be scraped; there’s no mark there. It’s so high – scrape slowly. Feel the red cinnabar powder and test it
Come and learn*; there shouldn’t be a line in the axial direction. Readjust the side clearance and top clearance.
