Method and Apparatus for Monitoring a Contact between Two Surfaces

摘要

Method for monitoring a contact between two surfaces, particularly two surfaces moving relative to each other, which contacts between two surfaces appear in sliding and rolling bearings, in gear trains, and in other sliding or rolling contacts of a machine construction. In the method, a recess (5), which has a bottom (3), is created behind the first surface (8) in the contact, and which recess extends towards the first surface (8). A detection device (4, 10) is placed at a distance from the bottom, so that a detection space (2) is formed between the detection device (4, 10) and the bottom (3) of the recess. Now the detection device (4, 10) can be used to monitor the changes taking place in the detection space (2).
