Hi all,
Our tray stacker is a 4 bar powered with 1 motor at a 1:7 gear ratio.
This setup worked with at most 4 cubes being stacked but more than that, it does not have enough power to lit up.
How can we make it stronger without adding another motor?
I feel like other teams can accomplish much more with one motor even with a smaller gear ratio.
Attached are some photos of the mechanism.
The effective gear ratio of a tilter 4-bar is based not only on the gear output itself (in your case 1:5), but on the length of the driving arm.
To strengthen your tilter, decrease the length of the steel channels and increase the length of the standoff.
But then the downwards limit of the tilter would be much higher making it difficult to put in cubes. Any other ways to do it?
have you tried using rubber bands? if so use even more. legend has it that doubling the bands will double the power
a 1:5 ratio is a bit greedy on a tilter. try 1:7
Sorry we have a 1:7 not a 1:5.
The one in the picture that you’ve shown is not 1:7. It’s 1:5 as others have stated
The driven gear is a 60 tooth gear (connected to the steel arm), and the driver gear is a 12 tooth gear (connected to the motor).
60/12 = 5 revolutions of the 12T gear for every revolution of 60T gear.
To do 1:7, use an 84 tooth gear instead of the 60 tooth gear.
Oh, right. Sorry for the mistake.I will change the gear ratio.
Hey this might help with adjusting the lengths of the two linkages.
