Re: Titanium chain & sprokets
Here. (Scroll down to "Chain".) It costs $700 (AUD) for one bicycle chain; plan on using only 73% of that, if you want to stay within the cost limit.
Alternatively, Tsubaki sells some (scroll down to "TI Titanium Roller Chain") that might just conform to ANSI specs. Contact any of their local distributors (on their site) for pricing and lead time. If I might hazard a guess, they're going to say that it's a special order with a minimum quantity, costs about $200 (CAD) per foot, and that they will need 14-20 weeks to process the order. You might have better luck, but I doubt it. While I'm in a Tsubaki state of mind, let me point you to their catalogue, which contains a lot of good engineering information. Section 1, pages A-6 and A-7 (in Acrobat, 17 and 18) have horsepower charts for #25 and #35 chain; consult those--you might be able to get away with #25, instead of #35, if that's what you had in mind. That's a significant weight savings, if it can be done. Last edited by Tristan Lall : 26-01-2005 at 12:48. |

Re: Titanium chain & sprokets
Notice how Tsubaki titanium chain is marketed as high temperature and anti corrosive, not high strength. Titanium chain is a bad idea.

Re: Titanium chain & sprokets
Titanium sprockets and chain are commonly used in bicycles. There's a few problems with that though. It's still expensive, the chain and sprockets are slightly narrower than #35 chain, so you aren't going to be able to bum replacements off someone at a competition.
Also, they come in very limited tooth counts. You'd also have to make an adapter to mount them to a shaft/wheel with, since they mount onto the cassette very differently than you would mount a sprocket to a shaft in FIRST. Overall, really not worth the effort. Just use #25 chain and sprockets [edit] The chain alone is going to run you $350 each, and you'll need 4 of them. The cassette is $150 each and you'd need 4 of them assuming you want to make a 4 WD robot. And then you'd need to buy a set of chainrings, which are also going to cost you a pretty penny. There's no easy or cheap way to do it Last edited by Cory : 26-01-2005 at 13:09. |
