3D打印 能动的机械时钟(分享所有STL 文件) 电路方案

这是一个复杂且拥有古老神话传说的机械时钟,现在我将其一个个旋转机械齿轮模型转化成为简单的 3D模块。 该设计表明了 3D打印技术的作品不仅仅可以当做装饰用,可以创建智能、并且能动的物体。 该机械时钟由锚式擒纵机构、平衡轮螺旋弹簧等组成。时钟能够显示秒、分钟和小时。绕组有嵌套的行星齿轮,它允许时钟一直运行下去,直到机械时钟发条停止运行。 3D机械时钟截图: 附件内容截图: 更多介绍: Everything is 3d-printed (even the spiral spring), except e few small screws, some metal pins, the cord, and the lead for the weight. This video shows the clock and the building process (actually with a simpler ratchet-winding): https://youtu.be/HgZBPYJ2Y-w Designed with Blender. PLA printed with Rapman 3.2. Some parts require a loose clearance (hollow shaft for hours and minutes), other parts require a press fit (hands). The 3d-files are optimised for older printers with more inaccuracy in xy, or a badly guided z axis. I.e. when printed with a newer generation printer, parts are most likely too loose. In order to compensate this, the material flow could be increased (over-extrusion). In Simplify3d there is another useful parameter: "process settings / advanced / other / horizontal size compensation". Pins: 1 x Balance wheel: 1.5mm diameter, 40mm length 1 x Escape wheel: 2.0mm diameter, 28mm length 1 x Reduction gears: 2.0mm diameter, 60mm length 1 x Drum Transmission: 3.0mm diameter, 60mm length 1 x Drum Axis: 3.0mm diameter, 60mm length 1 x Crank transmission: 3.0mm diameter, 30mm length 4 x Planets Axis: 3.0mm diameter, 39mm length 1 x Weight Axis: 3.0mm diameter, 15mm length Screws: 6 x Frame: M3, 12mm, Flat Head 5 x Winding Drum: M3, 10mm, Flat Head There are STL-versions with 2 x 2 combinations for the winding: a) Simple Ratchet v1: 4.22 revolutions per hour (weight moves 26.5cm/h) b) Simple Ratchet v2: 2.25 revolutions per hour (weight moves 14.1cm/h) c) Planetary Drum v1: 3.01 revolutions per hour (weight moves 18.9cm/h) d) Planetary Drum v2: 1.61 revolutions per hour (weight moves 10.1cm/h) My clock works well with version c) and 1.2kg weight. For version d) I'd probably need a weight of 2.3kg. The actual needed weight depends a lot on the friction of the whole system
