<p>The mainspring is formed from a metallic glass monolithic ribbon, where thickness of the mainspring amounts approximately between 50 and 150 micrometers. Shape of the mainspring in a free state is defined by a radius of an nth turn in a wound state so that the mainspring, which is wound into Archimedean spiral, is stressed to the maximum bending stress over the entire length. The radius is produced by adding the radius of a barrel core with multiplication of a number of winding turns and the ribbon thickness.</p> |
