  • Method and measuring apparatus for measuring a thread
    Patent number: 11879728
    Abstract: A method for measuring a thread includes moving a contactless distance sensor parallel to an axial direction of the thread, recording a measurement signal corresponding to a distance of the contactless distance sensor to a top of the thread, comparing the measurement signal with a reference value lying between a maximum value and a minimum value of the measurement signal, and determining intersection points of the measurement signal with the reference value. Further steps include combining pairs of intersection points, directly following one another, into measurement value tuples, calculating mean values of the measurement value tuples, and calculating a time-angle resolution from the mean values. In an example embodiment, the thread is for a spindle of a ball screw drive.
