chiaphua gear cluster

[Antonio]

do any of you remember the number of teeth that was on the cluster gear for the chiaphua motor

[Aaron Lussier]

8 but this year the Chiapuha has a shaft not teeth why do ask?

[Rob Colatutto]

no, the chippy output was 8, the cluster was 32 (or 25, or somewhere around there)

[sanddrag]

You may be able to find it in last year's kit details here.
http://www2.usfirst.org/2002comp/kit_p_hlist.pdf Warning very large file.

[Antonio]

sanddrag, no it doesn't list it on the file, but thanks anyway.......but do you think we will be able to order that cluster gear from the Chiaphua company again, or do you think it was customly designed for last year's competition?

[dlavery]

The 2002 Chiaphua output shaft have 9 teeth. The cluster gear has 44 teeth on the input side, and 16 on the output side. The motor output shaft and input side of the cluster are some strange pitch size that I don't remember (I have the motor in front of me, but don't have my tooth guages with me). The output side of the cluster is 32 pitch, 1/2" face width.

Hope that helps.

dlavery, yeah it will help a lot, thanks, if I can't find a place that have them in stock, but would you guys know where I can get those clusters again?? like from the Chiaphua company or something like that?

That's right. The output shaft on this year's CIM motor is a keyed shaft and not that weird gear last year. It will be illegal to use last year's chiaphua motor with the gear cluster on your robot this year.

[Antonio]

why wouldn't you be able to use the gear cluster from last year, isn't it just a normal gear? and you're allow to use last year's Chiaphua motor according to the team update #2

[Ken Leung]

My mistake then.

However, the gear cluster was a huge pain to use last year. You might be better off with this year's keyed output shaft.

[Antonio]

Ken L, that's alright......yeah I know there sort of a pain, but we bought two extra from last years, and for some reason we feel like last year's one is more powerful.......plus we're planning to use a similar gear shifting design posted by dlavery for team #116


so anyway, do you guys think I would be able to get the gear clusters from CIM again?

Hey, send one of those my way! We're using the cluster gear from last year too, and need a few of them. Anyway, I've got a question for all of you - what model is the Atwood Mobile jack that the CIM/cluster gear came from? I can't remember (and yes, I tried searching but did not find anything.) Thanks

[Antonio]

Katie, we should help each other than LOL, because I have no luck in finding those gear clusters yet, apparently the guy that designed the chiaphua motor last year, and probably the gear cluster that came with it as well, left the chiaphua company so we can't get any help from Chiaphua company. I think we might just need to use the specs that dlavery gave us and have it customly made

From what I've found, in order to get the actual cluster gear ... you have to buy the actual jack it comes in. So far the cheapest I have found the jack is $177 ... but that's a lot to pay for a little cluster gear! I'll keep in touch if I find anything else out.

- Katie

[Antonio]

how do you do that?

because if worse comes to worse I guess we can buy it if it is necessary
