Fixing device for two relatively movable components - has small solid bodies filling space between screw shaft and bore wall

摘要

One of the components has a bore larger than the shaft of the screw and the space between the shaft (9) and the wall of the bore (11) is filled up with e.g. metal balls (17) to provide a positive locking connection. After tightening the screw the maximum possible force is transferred which is determined solely by the sheer resistance of the screw. After loosening the screw however the two components can be adjusted relative to each other. During the adjustment movement the filling bodies move like a fluid around the screw shaft and fill up the cavities. If the screw is then tightened again the small filling bodies are pressed strongly against each other ensuring the positive locking connection. ADVANTAGE - Renewed adjustment of the components is possible after each time the screw has been loosened.
