Wow! I thought worm gears were designed for heavy torque loads! Intriguing to see the comparison between regular gearboxes. Informative! Ps i just love how watching someone else's semi-chaotic experimentation can be so satisfying.
Thanks a lot for this video (especially with my comment on your previous vid). I was really expecting worm gears to perform better. It seems friction it holding them back, not the ratio. Looking at the comparison of the worm vs regular gear there is much less friction in the regular gearing because the ratio difference is much smaller. Higher ratio=more torque=more friction. You could probably increase the regular gearing method by using smallmediumsmallmedium a multiple times compared to smalllargesmalllarge. Even better , because the ratio of the worm gear compared to a regular gear is much higher they still could have use in a smaller package. I suppose that's the trade off here :) The benefits of the worm gearing also is the worm gear can spin the regular gear, not the other way around. This prevents spin back of the load when the motor is idle. As for the axles, yes, you are reaching the limitations of a single axle . All that ratio transfer has to go somewhere thus the axle takes the grunt force, which is friction, which is heat, which results in warping. No surprises there :) The more steps with less ratio difference is easier on the axles, that's why with more gears the axles can take so much more. Add a pulley system would factor X the load as well, but off course increase the length of the "cable". As for the people commenting on the fact of using metal parts...sure , you could make everything out of metal and that would surely surpass the performance of plastics, but that would be beyond the point doing this with lego (tm/r/c) right ? Once you go with a metal part in the construction the next plastic thing will fail until you make that out of metal and the next thing etc. It's awesome to see how far pure plastic parts can go above and beyond with what you would expect with common sense engineering. Alright, enough, keep up the good stuff !
these are really useful for more things than one may think. I used this as a rudder engine in my rc boat since I scrapped a newbright rc car, and it didn't use servos to steer, so i just have a motor connected to a worm gear box to the rudder. Works great.
@@mikakorhonen5715 the only way to increase the load of the axles would be to use multiple axles through gears and wind around that. He haven't reached shear yet, just torsion. That's why I suggest steel, we know we have reached failure point for a single axle, what will break next.
Yeah, the reason worms didn't radically outperform the normal gear-based system is that his normal gear pulley attached the string in two locations, whereas the double worm gear setup had only one spot
A quick note: a rigorous statistical analysis of black vs grey swirls can be done based on your data! The null hypothesis (or status quo) would be that they are equal, and the alternative hypothesis may be that the black ones are better. The underlying model might be that the two swirls come from normal distributions with certain means which may be different (and for simplicitly, equal variances, although you can change this assumption). FInally, you could just calculate the probability of your results given that the two swirls have equal mean tolerances, and infer a conclusion about the null hypothesis from there!
Some commentator above did a one-tailed t-test (whether or not the assumption of normality may hold) and could not find evidence for black ones being stronger (p = 0.698)
Worm gear has about 30% of efficiency regarding standard transmission that is why there are not used in trial truck for instance. Interesting experiment about the silicone grease !
What about worm gears in ball-bearing steering? At 5MPH I can't tell the difference between the effort required for my 78 corolla steering vs my 01 camry steering.

I never would have expected that result. Thanks for running that experiment.
Love your vids, keep up.
So the worm gears and the gearboxes allow for more compact / simple builds, at the cost of 20-40% efficiency.
Pretty sure the cost should be multiplicative here so I guess that’s like you lose half or even more of the efficiency.

Just lube it up get some efficiency back
