Supporters Ian_Gere Posted September 18, 2013 Supporters Share Posted September 18, 2013 Taking 18:1 as a standard ratio, count the teeth. High speed gears will have less, high torque more. I don't know which gears are altered or whether it is all of them, but less/more teeth is how it's done, the same as gears on a bike. Link to comment Share on other sites More sharing options...
alex90 Posted September 19, 2013 Author Share Posted September 19, 2013 So not the case of spinning the secter gear once and seeing how many time beavel gear turns Link to comment Share on other sites More sharing options...
Supporters jcheeseright Posted September 19, 2013 Supporters Share Posted September 19, 2013 that works too. one turn of your sector gear will equate to 18 turns of the motor on an 18:1 set. Link to comment Share on other sites More sharing options...

Supporters Ian_Gere Posted September 19, 2013 Supporters Share Posted September 19, 2013 Damn difficult to see how many times the motor gear spins though, eh? Link to comment Share on other sites More sharing options...
Supporters jcheeseright Posted September 20, 2013 Supporters Share Posted September 20, 2013 easy, bit of pen on one of the teeth, count how many times it goes round! Link to comment Share on other sites More sharing options...
Supporters Ian_Gere Posted September 20, 2013 Supporters Share Posted September 20, 2013 How tf are you going to have the motor gear in contact with the bevel gear and see it spinning? Link to comment Share on other sites More sharing options...
