Abstract

Method for measuring the bearing play in a highly dynamic mechanical transmission chain between a setting member and a functional member on which it acts, wherein a control unit actuates the setting member with a square-shaped desired signal of at least half a period and a measuring device is provided with a sensor for sensing the position of the functional element measures its distance from a reference point of the functional element, and the bearing play is determined from the comparison of the actual deflection with the command signal of the setting member.
