Why are the centers of the bearing seat holes and the shaft deliberately made eccentric?
Thread Content
Today I saw a drawing in which the center line of the bearing seat hole and the center line of the mounting shaft were set to be eccentric, with an offset of 0.05 mm; as a result, there was a radial deviation of 0.05 between the center line of the shaft and the center line of the bearing hole. It’s unclear why it was processed this way ?
I’m not quite sure; does the assembly diagram show that the bearing housing and shaft are eccentric after installation? It might be to compensate for the centrifugal force acting on the rotating shaft
