Question:

When axle gear ratio is calculated?

When off road magaZines talk of axle gears and the ratio, are they talking about the ratio of the ring and pinion or something else. They will refer to it as , for example 3.43 axle gears. They are not talking about the diff. side gears.

Answer:

i will grant you with a large clue: One enamel on the using equipment strikes the pushed equipment round by employing 1 enamel. So for any pair of gears in mesh, % * sort of tooth a consistent. So once you've 34 tooth turning at 15 rpm, that is 510 tooth in accordance to minute. And the equipment using the single with 34 tooth has 14 tooth. That too might want to be doing 510 tooth in accordance to minute; i.e., 36.40 3 rpm. there is yet another equipment on the same spindle, so it ought to also be turning at 36.40 3 rpm, regardless of the indisputable fact that it has 34 tooth. That makes 1239 tooth in accordance to minute. And the equipment on the motor has 14 tooth, so no matter if that is popping at 1239 tooth in accordance to minute then it would want to be making 88.40 seven rpm. desire that facilitates.
i also suggest u got wildy to mine. its really good there, usually not many ppl r there, but there r high lvl ones passing by to pk or kill greater demons at lvl 40+ wildy
ok that means ur over 60 mini so join minig guild they got sum sweet stuuf that u ned down there
The 3.43 is indeed the ring and pinion or the ratio of input to output. The differential gears simply allow for equal torque between the rear wheels, they do not in any way effect the ratio. They simply allow one wheel to travel differently from the other as in making a turn, while maintaining equal torque or applied force to each.
Axle gear ratios are obtained by calculating the Ring gear count, and dividing the Pinion gear count. Example: Ring gear tooth count, 41 teeth. Pinion tooth count, 11 teeth now divide the pinion tooth count into the ring gear tooth count, and you will get the figure of 3.727272, which equals 3.73:1 ratio.
