Re: [TANKS] trying to figure out rpm's / track speed

[Derek Engelhaupt <derekengelhaupt-at-rocketmail.com>]

According to my quick math, your output shaft speed would be about 240 RPMs with that setup.  Once again from what I know, you don't need to be concerned about the size of sprocket driving the tracks, but the final shaft speed after the reduction.  In the case of "Master Tying", I believe his final shaft speed is in the 500 RPM range IIRC.

anyway, I am a bit stuck on working out the rpm's in one spot............

 

the motor's max rpm is 2600 rpm -at- 24vt

 

motor gear 10 tooth to first gear 36 tooth

second gear 12 tooth (on same shaft as gear one) to axel shaft 36 tooth with a ttrack drive sprocket of 3.9" / 9.906 cm and that will have a cir. of 12.25"/31.12 cm

 

anyone have a easy way to figure this out? just trying to see if i have a decent rpm/speed range
