WatchTech

hello~~ everybody.~~ i have something(idea) to share with people who like the watch. actually i have a idea, but i am not sure that is good or bad. there is nobody who i can ask...... at first i am sorry that my bad English. the idea is the way to control...  

it would probably take much experimentation to discover the right friction and the curve of the cam which reduces that friction on the pinion. But it seems logical that this could work - the question then is will it add so much friction that it reduces th... 

Search for "stackfreed" mechanism. However, I believe this is more appropriate for the past when metallurgy for hairspring technology etc are limited, so constant torque was more important to achieve isochronism. Today in modern world, it is not as big a ... 

i have experience.....this days... there is many watches(manual winding) which has long power reserve, 8 or 10 or 15 days...... when the watch is fully winded, there is knocking problem. there is problem very often.!!! (automatic watch also has same probl... 

If you use the friction spring on the seconds hand, it is a known solution to prevent "flutter" of seconds hand (no shaking). However, the second hand in a watch geartrain is heavily geared up - When mainspring power is high torque but low speed, the gear... 

I can understand what you said.~~ and i agree with you.!! You can check first drawing, friction spring not touch the second wheel, it touch the 3rd wheel, i think friction spring can be touched at great wheel(2nd wheel)..... I just want to make friction s...

It seems like the click is the most logical component to register varying pressure from the barrel without affecting the rest of the train.

as shown by the old stackfreeds which were more or less exactly what you suggest. The main problem with the system is that you are adding friction to reduce the torque that gets to the escapement when the barrel is highly wound. You reduce this friction a... 

You are right.!!~~ It is very similar with "stackfreed". But .... not exactly same.!! This idea was started by knocking problem.! I just want to reduce over torque which make knocking.! Because it is very easy to find knocking problem some calibre..!! And... 

And it's look like this: ...  

I think, that with friction alone it would be impossible to limit the torque with sufficient accuracy to provide continuous torque for the escapement
