is there a good gear ratio between 1:5 and 1:7
for my lift 1:7 has too much torque, is too slow for my lift.
and 1:5 has good speed, but the torque is not enough
Have you tried a gear ratio of 1:7 with high speed motors? In theory, that should fix your speed problem. What do you mean by “too much torque”? In this game, I don’t think that too much torque is a question to be asked, but “How many game pieces can my lift hold without falling?” and “Is my lift fast enough?”
in other words, it is too slow, for my lift
A 1:7 with speed motors will be 1.6:7, which is 1:4.375, otherwise known as a bit less torque than 1:5.
Is your “lift” a dump or hang?
Try adding more rubber bands I guess?
If you are fine with adding chain you could use turbo motors with a 1:14 external gear ratio (1:2 with chain and 1:7 with an 84 tooth gear). This would be a 1:5.83.
Otherwise, for slightly more torque (and no chain), you could use turbo motors with a 1:15 external gear ratio (1:3 and then 1:5 with gears). This would be a 1:6.25.
to which gear should i connect my c channel to 1:3 or 1:5
because i have a 6 bar, should have one of the gears, connectd to the 1:5 and have another gear on top for the other ch channel
it will look something like this,
and can this be done wit speed motors
both
You would connect your c channel to the 60 tooth gear (1:5 gear ratio).
You would not connect the other bar in your six bar to a gear (just have it on an axle or screw).
If you used the 1:15 external gear ratio (1:3 and 1:5), you would use turbo motors.
is there any other combanition without using turbo motors
You can do a 1:9 (1:3 then 1:3) gear ratio with speed motors. That’s 1:5.625. That’s the only one I can think of.
Yeah, if you use a 1:9 external gear ratio (1:3 and 1:3), you can use high speed motors to achieve a 1:5.626 gear ratio.
Alternatively, if you want slightly more torque, you could use a 1:10 external gear ratio (1:2 with chains and 1:5 with gears) with high speed motors to achieve a 1:6.25 gear ratio.
Edit: @Ipieroni beat me to the 1:9 gear ratio.
both are a very good gear ratios, but using chain on a lift doesn’t seem like a very good idea, and i guess 1:9 is seams like my only my option left
but if i used the 1:10 gear ratio, would t look something like this
edit - my lift has 4 motors total
can i ask you all how you calculated the gear raitio, correct me if i am wrong.
for eg the 1:9 gear ratio,
1:3 times 1:3 = 1:9 divide ?? = 1:5.626
The internal gearing for high speed motors is 1.6:1.
1:3 * 1:3 = 1:9
1:9 * 1.6:1 = 1.6:9 = 1:5.625
thanks
what about torque and turbo motors
Torque is 1:1, turbo is 2.4:1. These numbers are available on the 393 Motor product page.
We use 1:5 with 8 rubber bands.
