General Discussion / prototype escapement problems
« Last post by Tim on October 06, 2014, 06:08:26 PM »
Hi, I'm making a wooden clockwork mechanism using a double three-legged escapement. I've rough-cut some parts with the plan to get a prototype working and then develop a good-looking finished model based on the dimensions. Anyway, the pendulum loses energy after just 20 or so swings, so something is very wrong. But what, exactly?

There are so many variables - weight and length of the arms, weight of the pendulum, distance the arms are lifted by the three pushers, etc. Does anyone know of a diagnostic procedure to narrow it down?

It seems like all the gears before the minute hand could take advantage of this feature.  It may require an escape wheel with a prime number of teeth and a pendulum with a slightly different period.  Eventually, the minute hand needs to rotate exactly once per hour.

The gears between the minute hand and hour hand are really slow moving, so don't really have an issue with wear.

Its a common practice in geared devices to choose prime number tooth count for the reasons you mentioned.  However, this applies where the exact gear ratio is not so critical, such as in a car's transmission.  The problem with using this in clocks is that the ratio of 2 prime numbers cannot be an integer.

However, you only really need integer ratios for gearing the hands together, while the rest of the power train can be of prime toothed gears.
