Wooden gears can last a very long time. In fact many early European clockmakers preferred to make their mechanism out of wood because wooden gears do not grind away at one another like metal gear trains do. Also as wood is porous, it can absorb oils and can be self lubricating. Some of these clocks are hundreds of years old and can still keep very accurate time. For example, in 1727,John Harrison who is the inventor of the first marine chronometer built his clock "Precision Pendulum no. 2" At the time it was the most accurate clock in the world keeping time to give or take a second a month. It currently resides in the collection of the Leeds City Museum and its movement is made mainly of wood. Thanks for all of your great videos, Keep up the good work!

Hi Matthias, I like your experimental aproach. In the Netherlands all the old windmills use wooden gears. Alltough they are build as wooden disks with the tooth wedged in to them axialy because the main shafts are all at an angle. I think you might be interested to research this a bit, especially because for every component of the mill a species of wood is selected for its mechanical properties. Two things that I learned from a miller you might want to incoorporate in the power transmission aparatus that you plan to build: 1; use beeswax to grease the gears. This gives a thin but slick coating on the surface. 2; make sure that when you devide the amount of teeth of gear A trough the amount of teeth on gear B you don't get a whole number. This ensures that the same teeth meet occasionally and the ware on your teeth is even. For power distribution this is ideal because you can reduce the play in the gears and thus the noise.

Harrison built clocks with wooden gears, a few of which are still in existence today, some 300 years later. He used quarter sawn oak for the disks, and the teeth were cut out of a separate piece and placed in the disk with the grain extending radially to utilize the grain strength. these weren't involute gears, but still lasted exceptionally long.

Well, if you know a bit about clocks, you might know that there is an oak tower clock made by John Harrison that has been in continuous use since it was installed the 1720s. I believe the clock has only been stopped occasionally (maybe 3 or 4 times) for maintenance. It was made with brass pivots (hardly no steel was used in the clock due to moisture concerns that may cause rust) running in lignum vitae bearings (a naturally oily tropical wood). The clock needs no lubrication. The wheels were made with 1/4 sawn oak blanks, with sections of teeth inserted into the edges of the blanks, so that all the teeth would run radially for strength. I would think that the Baltic Birch plywood would last an exceptionally long time (perhaps eventually wearing a striped pattern into the mating gear). There are also several weight and spring driven clock kits that are made using BB ply.

MDF is actually very good for noise reduction. On my hand powered, gear boxed, forge blower, there's a plastic gear that's meant to reduce noise between metal gears. I replaced that with an MDF one some, well about two months now. Still works, hasn't chewed up much, and VS the plastic one, there's a considerable noise reduction. One other thing, it was cut on a divider head and a mill (so there's that) and i've dipped the gear's non driving side of the teeth in super glue, the really runny kind used in RC models, to give it a bit more structure. It's a trick i use when i play with geared thingamajigs. Dip the gears in a small disposable tub of super glue and then recut them on the machine. Extra strong gears because the MDF sucks it up.

Well, it all comes down too how well the gears are made, how well they are set up, and how well they are maintained. If the gears are made accurately there will be no excessive contact on the teeth slowing down wear. If the gears are spaced properly, not to tight to enable binding and not so far apart to enable slipping and grinding is another factor. Also whether having the shafts in bearings or not and whether they were lubricated is another factor. And lastly, keep them clean and and in the case of a continuously running machine keep them lubricated.

the only reason for metal gears is size and torque load. you can make a considerably smaller metal gear set to do the same load of work for lighter weight. you also need metal where the input torque load would simply just shear off the teeth of the gears. You maybe have 90rpm there at most with the gears being even. Several electric motors get upwards to 2500-3000rpm. More revolutions more chances for things to break down.

The harder material will always consumer the softer. For best longevity I would go with the same wood for all mesh parts. That will last longest. Even if you had to option of two pine gears, or an oak and a pine gear. I'm pretty sure the two pine gears would last longer as they would resist destroying each other.
I was thinking the same thing. If you have a harder and a softer material the softer one will get all the wear. This might be useful in a drive train when it is extremely difficult to replace one gear.

+YeCannyDaeThat nope, there's still the same energy applied that needs to be transferred, and same amount of joules will destroy the same amount of material divided by their UTS in a taken finite element. But there is a value before which material is able to completely recover, so if your elements stay in it - your item will idealy be inderstructible. I.e. when you need to triple your speed by means of gears, if you make two gears - a large one and a small one - surfaces of both gear's teeth will be loaded to the point of destruction (even if it's very small and will take weeks or months to become visible). But if you make three or four smaller gears from same amount of material (i.e. instead 60 to 20 teeth you make 30 to 20 to 10 optionally to another 10 for reverse direction) the same force will spread proportionally between bigger summary surface and will wear out slower or not at all.

If? your gears have the correct curved tooth shape, (involute curve) then those have been developed over centuries to be the best wearing and least friction for there shape. And having two different materials will help with the wear most times. Like any gearing, once they did start to break down due to wear. Then as the sawdust from that wear pass through the gearing time after time, that will greatly accelerate further wear. And if I really was going to build an all wood clock? I'd want the best chance of it actually working and keeping reasonable time. So I'd use my mill, dividing head, and buy the proper gear cutters so I did end up with as accurate as possible gearing without any tight spots. I think I'd also choose a naturally oily wood also. Lignum Vitae would be one as someone else mentioned I think.

Hello Matthias, if You want to endurance test Your gears without using a load and a powerful motor, try to build this rig: two parallel long shafts (torsion bars) having at each end one gear set. Three of the four gears should be fixed on the shafts and the fourth should have a device that can apply an adjustable torque to the shaft . The motor will drive one shaft and will only have to cope with the friction generated by the mechanism. The two gear sets will be in a close loop, circulating a lot more power than your motor can produce, and there is no load needed.
