Gears ratio
Hey Is short gear stronger or long gear stronger ???
And what would u perfer and y |

Length of the gear doesn't depict the strength.
Width of the gear generally controls strength due to the larger surface area. Straight cut gears are generally wider I think..

sorry but just a question, don't know shit about the insides of a box but, when u say "straight cut" is that haveing the theet cut sideways through the gear?? if so wouldn't a "angled cut" gear be stronger with the larger surface area?.. plz correct me if i have missinterpeted the meaning here

All your answers are here, in regards to straight vs helical cut.

Its a good point, because the speed the shaft is spinning will affect the force applied to the gear...

Yeah, you'd think a helical gear is stronger than a straight cut because the tooth angle creates an extended length of contact, which results in a higher tooth contact ratio and the load being distributed over a greater area.
BUT, a straight cut gear has a better directional load placed on each gear tooth, which therefore makes them strong also. The MAIN reason they are used in a performance gearbox, is they are easier to cut, they provide much less friction and they dont suffer from thrust loading, which can place strain on bearings and gears.

I think you are asking about gear ratio's ?! Short Gear ratio's will give good torque/acceleration but a lower overall speed. Long gear ratio's will give you a lower torque/slower acceleration but a higher overall speed.
