Determination of tolerance of thin-walled copper sleeves during press-fit

When the thin-walled copper sleeve is inserted into the seat hole, the sleeve-to-seat hole is generally an interference fit, and is pressed into and into at normal temperature, and the inner hole is contracted, which changes the nature of the original clearance fit, and can only be re-reamed or bored. Hole tolerance requirements. In order to ensure the clearance fit between the sleeve and the shaft, the determination of the tolerance of the bore is crucial. After the thin-walled copper sleeve is installed in the seat hole at normal temperature, the metal density does not change much and can be omitted. Therefore, the cut-off area before and after the sleeve is inserted into the seat hole should be equal, as shown. The solid line is the section before the insert is set, and the dotted line is the section after the sleeve is set.
