What's the embedding for division and modulation into systems of gears? I imagine it's somewhat expensive.

- Someone 10y agoMultiplying angular velocity by a constant is easier than adding a constant angular velocity. To multiply by m, use two gears with diameters in ratio m:1. To divide, switch the gears. I wouldn't even know how to subtract a constant angular velocity. I don't think you need that, though; if you know at what speed all your gears will rotate, a constant addition/change can be replaced by a constant multiplication/division: a+b = a * (a+b)/a
- pavel_lishin 10y agoIf the angular velocity doesn't have to be constant, could you skip gears?
- thechao 10y agoDifferentials have the property of being universal angular velocity adder/subtractors at fixed ratios. output := K * (input0 + input1) / 2 Spur-gear differentials are suitable for watches.
