道高一尺 发表于 2013-1-13 22:55 这倒是对路，专利期估计能够保护不少好东西，当然也能够毁掉不少好东西，什么东西能不是双刃剑呢？  |

OHSEAL 发表于 2013-1-13 06:00 马式擒纵的发展前后也用了差不多三百年吧？之前在表界叱诧风云的擒纵估计发展时间只有更久，世界只有变幻莫测啊。。。不过，个人对这些所谓“技术革新”也是冷眼旁观，毕竟机械表早就不是1970年代前的机械表了。 |
道高一尺 发表于 2013-1-13 05:49 讽刺的是，历史上专利保护过的技术基本上都后继乏人。 |
机械米 发表于 2013-1-13 03:34 由此可见，奢侈品行业就算再仰仗文化噱头，还是要靠技术上的噱头帮助造势的，两者可谓密不可分，合则两利，分则两害。 |

nomorewatch 发表于 2013-1-14 11:10 操来操去  |
chn6 发表于 2013-1-13 19:33 这应该可以说是把笛卡尔的渐开线理论发展到极致的一个例子了。。。主要的改良在于擒纵齿形，通过这种改良来降低摩擦，以现在的加工技术，应该可以达到效果，而且风险更低，问题在于怎么大批量生产后控制成本。 |

本帖最后由 chn6 于 2013-1-14 11:34 编辑 ROLEX 于上述擒纵专利之后的2010年12月8日，又提交了一个擒纵专利。 http://www.google.com.hk/patents/US20110149696 SWISS LEVER ESCAPEMENT Raphaël Cettour-Baron et al This Swiss lever escapement comprises an escape wheel having teeth, and a lever having on the one hand an entry pallet and an exit pallet that engage alternately with the teeth of the escape wheel, and on the other hand a fork that engages periodically with an impulse pin on a roller mounted on the staff of a regulator balance wheel. The relative width Lpl of each of said pallets, expressed as a percentage of the sum of the lengths of arc of one of said teeth and one of said pallets, measured at the circumference of the escape wheel is: 发明者: Raphaël Cettour-Baron, Alexandre Chiuvé 原受让人: ROLEX S.A. 当前美国分类号: 368/131 在美国专利商标局 (USPTO) 网站上查看专利 搜索美国专利商标局 (USPTO) 转让数据库 声明 1. A Swiss lever escapement comprising: an escape wheel having teeth, and a lever, wherein the lever comprises (i) an entry pallet and an exit pallet that engage alternately with the teeth of the escape wheel, and (ii) a fork that engages periodically with an impulse pin on a roller mounted on the staff of a regulator balance wheel, wherein the relative width Lpl of each of said pallets, expressed as a percentage of the sum of the lengths of arc of one of said teeth and one of said pallets, measured at the circumference of the escape wheel, is: Lpl = Ls Ls + d or Le Le + d ≤ 60 % where Ls and Le are the lengths of arc of the exit pallet and entry pallet, respectively, and d is the length of arc of one escape wheel tooth. 2. The escapement as claimed in claim 1, in which said relative width Lpl of each of said pallets is ≦45%. 3. The escapement as claimed in claim 1, in which the ratio of the length of arc Ls, Le of the exit or entry pallet, respectively, to the length of arc d of one of the escape wheel teeth is less than 1:1. 4. The escapement as claimed in claim 1, in which the length of the impulse plane La of one of said pallets is less than 200 μm. 5. The escapement as claimed in claim 1, in which the ratio of the length of the impulse plane Lg of one of said teeth to the length of the impulse plane La of one of the pallets is more than 1.5:1. 6. The escapement as claimed in claim 1, in which the ratio of the lift angle of the balance wheel to the lift angle of the lever is from 3.7:1 to 7:1. 7. The escapement as claimed in claim 6, in which the ratio of the lift angle of the balance wheel to the lift angle of the lever is 4.5:1. 8. The escapement as claimed in claim 2, in which the ratio of the length of arc Ls, Le of the exit or entry pallet, respectively, to the length of arc d of one of the escape wheel teeth is less than 1:1. 9. The escapement as claimed in claim 2, in which the length of the impulse plane La of one of said pallets is less than 200 μm. 10. The escapement as claimed in claim 3, in which the length of the impulse plane La of one of said pallets is less than 200 μm. 11.

The escapement as claimed in claim 2, in which the ratio of the length of the impulse plane Lg of one of said teeth to the length of the impulse plane La of one of the pallets is more than 1.5:1. 13. The escapement as claimed in claim 3, in which the ratio of the length of the impulse plane Lg of one of said teeth to the length of the impulse plane La of one of the pallets is more than 1.5:1. 14. The escapement as claimed in claim 4, in which the ratio of the length of the impulse plane Lg of one of said teeth to the length of the impulse plane La of one of the pallets is more than 1.5:1. 15.

PPBG 发表于 2013-1-13 18:18 其实现在的机械表基本都是天下文章一大抄，你抄我的，我抄你的，操来操去，到头来不知所谓。 |
nomorewatch 发表于 2013-1-14 09:59 pp的这个，运转起来乱七八糟。我不懂机械原理，但感觉不好。 |
nomorewatch 发表于 2013-1-14 10:00 R没动画，想象了一下运转情况，感觉和同轴一样，也是“小碎步”。 |
PPBG 发表于 2013-1-13 17:51 R的擒纵演变自冲击式擒纵，如果材料加工技术过关了，估计还是可以的。 |
PPBG 发表于 2013-1-13 17:42 其实PP的那款擒纵就是复式擒纵的基础上改材料，再加一套传动结构 |
| R的擒纵，感觉擒纵叉和擒纵轮的接触，类似同轴，对装配精度要求较高 |
| PP的那个动画，直观感觉摆轮上的那个蓝色的方形的装置，磨损会非常严重。 |
