摘要:
A method for detecting damage to a hollow shaft having no radially encircling notches, openings, or channels by: (a) positioning a sensor for transmitting and receiving a signal at an end face of the hollow shaft, (b) transmitting a signal and receiving an echo of the signal, (c) determining the signal propagation time from the time of transmitting the signal until receiving the echo, (d) comparing the signal propagation time to a predetermined intended value and emitting a warning in the case of a deviation.
