They are encoder mounts. They stick up to accommodate the gears that run the encoders. I'm not sure why they were done that way, as I was not involved in their design. |

Re: pic: WCD off season chassis from 2471
What lead you to choose to use tensioners with your design?
One of the major benefits of the in-tube design is that it's practically impossible for a chain to jump the sprocket, especially if the center-to-center distance between the sprockets is correct. Last edited by Ty Tremblay : 01-12-2015 at 18:18. |

Re: pic: WCD off season chassis from 2471
I was not involved in that decision, so I can't say for sure. However, I do know that bearing blocks were used so that the the frame could use .0625in wall tubing.

Re: pic: WCD off season chassis from 2471
Do I spy shock absorbers? Or is that black ABS for spacing?

Re: pic: WCD off season chassis from 2471
for your chain in tube design, are you using 2"x1" tubing? if so, are you using COTS sprockets? I haven't been able to fit 2 COTS sprockets into the tube. It would be great if anyone could tell me how everything was packaged together.

Yes, and yes. They are plastic spacers. We designed the bumper mounts that way to help insulate the frame from impact. This year's BunnyBots competition has no rule against high speed ramming, and looks to be highly violent.

Re: pic: WCD off season chassis from 2471
I'm not sure how cots sprocket don't fit? Do they not fit due to the diameter or the width of the sprocket or both?

I haven't looked into the 17 tooth double sprocket, but can you create a dropcenter with the larger diameter? I know the clearance is pretty slim already for 16t, but I don't know for sure with 17t. |

Re: pic: WCD off season chassis from 2471
Very nice and clean drive base. I want our team to look into a chain-in-tube design this year but I've always wondered how you assemble the chain and sprockets in the tube
Care to give me some insight on the procedure? Are there access hole on the underside? Has anyone ever done this with belts?Last edited by pribusin : 02-12-2015 at 08:07. |

If you are using 2 sprockets in the middle like we do we have a small piece of axle that we'll put through the two sprockets to hold them together during the drop and push that piece out with the final axle. Last edited by notmattlythgoe : 02-12-2015 at 08:25. |

Got it - thanks.
Are those 3" x 0.875" wheels? How are they kept from slipping off the hex shaft? |

Re: pic: WCD off season chassis from 2471
What are you using to hold the corners of the frame together? It's not clear to me

The 17t sprocket works in the 2 x 1 x 1/8 because it has a large enough pitch diameter that the chain clears the 1.125 bearing OD. Last edited by Nate Laverdure : 02-12-2015 at 10:32. |
