GEARING SYSTEM FOR A TIMEPIECE |
摘要 |
<p>The system (1) has a drive pinion (5) and a sprocket (7) mounted coaxially with respect to a pivoting axle (3). An attachment device (21) is placed between the pinion and the sprocket to avoid relative displacement of the sprocket with respect to the pinion. The device includes a footprint (23) having shape corresponding to a section of the pinion. The axle and the pinion are made of metallic material, where the system is made of silicon-metal, and the sprocket is made of microusable material selected from a group consisting of crystalline silicon, crystalline alumina and crystalline silica. An independent claim is also included for a method for fabrication of a watch element i.e. sprocket, made up of microusable material.</p> |
