Interference fit - measuring device and interference fit - measuring method

摘要

In the case of a process for the frequency analysis of knocking shades with the determination of the fixed seating of a shaft member, which is held by an elastic force, by means of tapping with a hammer or in a method for detecting a response to the displacement of the said shaft member in vibrations can be no sufficient accuracy for a determination of the fixed seating are obtained. For this reason, at a number of positions on the surface of the element a tapping force is applied, as a result of which a number of knocking is generated tones. From the number of knocking shades, use is made of characteristic variables derived. By taking the mean value, a mean characteristic quantity is determined. The fit of said shaft member, with the use of a correlation between the interference fit of said shaft member and the mean characteristic size from the average characteristic magnitude.
