Can anyone tell me the gear ratio for CIMLATOR banebot775?
As said on the banebots website, it’s a 2:7:1 reduction.
it says
Reduction : 2.7:1
is 2.7:1 same thing as 2:7:1?
Yes. it is 2.7:1 he made a typo. And you can always count the number of teeth on each gear. 27 tooth and 10 tooth.
Yeah, typo. It’s 2.7:1. For a single stage gearbox, it’s hard to get 2:7:1.
Ohh
so 19500 rpm would be geared down to 7800 rpm. right?
just making sure
thanks
Yes.
Oh and FYI, I’m pretty sure that the motor you are using is the RS77518… If so then it only spins at 13000 RPM at 12 volts giving it about 4800 rpm out of the CIMulator.
Three problems:

The free speed of the RS55012 is 19300. That’s not the motor you are planning to use is it?

19500/2.7 = 7222, not 7800.

RS77518 free speed is 13,000 not 19500 13,000/2.7 = 4815
