If you look at picture one then picture two, you will notice in the second
picture that all but the very last of the four gears actually has a second
gear cast onto it, making the three of them essentially two gears and not
one. What this essentially does is introduce a simple reduction drive
mechanism, also known in a lot of applications as a speed reduction gearbox,
into each gear, as it turns the next gear in line a bit slower.
I don't think you can turn these around, it would do little, and possibly
burn out the drive motor from excessive friction generation. Reduction
mechanisms are generally not intended to overdrive the gears they mesh with.

| What i guess Jurgen mean is that the two middle gears are meshed in both inner and outter gears, with will block the mechanism because the ratio diference. Unless the bigger gear of the second red gear is useless. Patrick. "Geoffrey Hyde" (...) (20 years ago, 7-Feb-05, to lugnet.robotics, lugnet.technic)

| Hi Geoffrey, (...) I know that, but the gears that I mean don't take part in the reduction, the reduction is essentially done only by the axis next to the motor. (...) I was only wondering why they would put two gears on an axis when the second one (...) (20 years ago, 8-Feb-05, to lugnet.robotics)
