I am studying implementation of 9398 crawler reduction. Here is the stripped part, in order to see the gears and their relation - the image is made with the excellent tool which is LDCad.
My idea is to use this Lego design for other model and I need to know how would I calculate the effect of changing it a bit. My intention is to replace the two 16 teeth gears 94925:
with a pair of 12 and 20 teeth (32270 and 32269):
and to remove the last reduction pairs, the ones in portal axle:
so it would be as follows:
Would this become faster/less powerful or slower/more powerful? My aim would be to keep it pretty close to how it performs now.
Also, is there a way to combine gears in order to add a distance of half of a stud between the motor axle and the next or the second one? In the image below, I have moved the parts and created a gap between the gears, in order to point what I intend to move, but the contact must be assured by some gears, obviously by replacing the existing ones. Would be there possible?
