Sorry, this is an old picture. We do have support for the gears.
but still just flip the motors and gears because i guarantee that the axle will twist with that set up and then you will have to spend quite a while fishing it out
Ok. Thank you for the help.
Did this fix your problem?
Anytime, let me know how it worked out for you
I also would like to see the completed robot.
Send the pictures here please: [email protected]
I will definitly try some of your solutions. I will also make sure to email pics to you.
Not sure if this has been said or not but you should move your motors so they are horizontal. This would make them closer and allow you to use a 12 tooth gear to connect them instead of a 60 (I think it was a 60). You lose power by having it geared up then down just to connect the motors. You could also use chain to connect.
I think chain would be a good option.
I agree with what Dbrayer said.
It was a 64 tooth gear.
It may not be “very heavy”, but based on your photo, the length of the torque arm (from end to your pivot point) is fairly long. I’m guessing that 12:60 (1:5) is not enough torque. Have you considered doing a dual-stage reduction (2 layers of gears on the sides, staggered, as in the photo)? It wouldn’t require too much redesign but could greatly reduce your gear ratio (1:25, or 1:15). We found that even using large gears, 12:84 (1:7) isn’t enough reduction if we use manipulators with long arms.
The gear reduction of 1:7 had enough torque and speed for the length of arm we had. I don’t think I want to do a 2 stage gear mechanism because then it gets really complicated and then there are more places for breakage.
I don’t like chain as well. Chain can break or get caught really easy and if I can do everything with gears, it should be fine.
What I think I will do now is attach elastic tubing to act as a counterbalance and then reinforce the 84 tooth gear with a smaller high strength gear kind of like using a lock bar.
I think you are now on the right path.
