Optical Measuring Method For Archimedian Flat Spirals And Spiral Springs With Optimized Geometry

Abstract: the invention relates to a spiral spring (), suitable for use in an optical measuring method according to any one of the preceding claims, with several turns () which extend along respective circular paths forming a spiral course, wherein the spiral spring () can be stimulated to an oscillatory movement, in particular for clocking a mechanical movement, with adjacent turns () being deflected relative to each other along their respective circular paths by an angular displacement (�), it is the object of the present invention to determine the oscillation behavior of spiral springs based on characteristic geometries, and, in particular, to provide a non-invasive, non-contact measuring method which can be used in automated assembly lines in line assembly in movement production. the object is achieved in that the spacing (x) between the adjacent turns () varies at least along a measuring section corresponding to the angular displacement (�).
