Gearboxes
We are building a shooter design, and were looking for a 12:1 gearbox. The motor we plan on using is the RS775 18v from BaneBots, and we can find a 16:1 gearbox, but what would be ideal is a 12:1. Has anyone ever bought/built one?

Re: Gearboxes
What if you took the 16:1 gear box and then did a 3:4 pulley reduction?
We are think about making a custom gearbox with 32dp gears, but we are not looking for such an extreme reduction. |

Why specifically 16:1? Are you going for a particular free speed, or do you need a particular amount of torque? |

Re: Gearboxes
This may be more work to adapt to your uses than you want, but the Dewalt gearboxes have 12:1, 15:1, and 47:1 ratios (12:1 is 3rd gear). Like Sh1ine and Chris is me said, its probably easier to just use the gearbox you have and perfect the ratio using a belt or chain, but the Dewalts are an option if you have to direct drive. There is a whitepaper somewhere that deals with how to adapt the Dewalts to typical uses in FIRST, but it does not deal with the Banebots motors (since it was written close to 8 years ago and we weren't able to use the RS775 until last year)

Re: Gearboxes
CIM-U-LATOR into a CIMple Box gives you 12.609:1
