Multiplier gear boxes are quite common in manual tractors. A lot of the one's built around and after the 2000's for example use a 24/24 6 speed with either 4 groups, or 4 intermediate gear that can be changed without clutching. Some 80's/90's Renault tractors also have a third optional box to make them a 24/24 from a 12/12. This was done by adding a two speed intermediate box to the already existing 3 Groups +4 Gears and Reverser box.

[@dangeary2134]

I have rebuilt transmissions from big trucks. It’s not as hard to imagine the building process as it’s all simply gears. To get the different ranges, one can simply add reducers and multipliers to a section behind the main gear set. The final drive is important here, as it needs to be matched with the horsepower going through the input shaft. The torque is managed by how robust the gears and shafts are, so little beyond making them hardy enough to stand the maximum torque is the simple part. Trading speed for the torque is the big trick, because the needed horsepower can be easily overwhelmed by just having too much at the final drive for the engine to keep moving!

[@christopherwinter2099]

Just gotta remember the equations and remember which gear is which though it does help that they'll all splice to together. Gotta love that diesel program in tech schools.

[@h7opolo]

5:34 your solution is to print the pieces separately, not as one piece, then attach them during the build because very little stress will be applied to their junction point.

[@frostfamily5321]

And screw them together. And I hope that Micro Center will sell housings for partially 3-d printed toroidal torque converters, which I hope can use thermometer alcohol as transmission fluid so that the heat can get squeezed out in a skinny pipe in front of and above the engine! But with a bike you need to use pipes connected together by rubber tubes held together by woven metal if rubber is insulating. P.S. The One Piece is real!?!

Depending on how strong it needs to be and how importand the asthetics are you could also lay it on the largest of the suggestet gray blobs. Then it is at an odd angle and you need some support but not that much and it is a lot stronger than the vertical solutions.

Essentially, if you put power to the other end (your current 'output' shaft), you've created a compound truck transmission.. similar to a Fuller/Eaton RoadRanger. They generally just have a low and a high set for the multiplier, and then 5 ratios behind that, in the case of the 10 speed. You basically run through the 5 gears in the low range and then pop the button up to shift to the high range, and row though the 5 ratios again until you reach the 1:1 ratio on the output. Pretty interesting experiment! A bit lighter than the typical 1000 lbs. or so for an actual compound transmission!😂

[@gearcheck101]

You forgot to mention the fact you've effectively duplicated many of the ratios, and that the ideal shift pattern wouldn't be 1 through 12 on 1x, 1 through 12 on 2 x, 1 through 12 on 3x, etc ect, but rather you may have alternate between shifting front and rear to hit all possible ratios in the correct order. But as I mentioned there is significant overlap, so they may be much fewer than 40 unique ratios. At the very least the 1:1 and 2:1 gears in the 12 speed will be duplicated by each successive gear in the 5x multiplier , IE, 2:1 in the 12 speed on the 1x will be the same as 1:1 in the 12 speed on the 2x...

[@chaintheguardien]

was about to say the same

[@mauricereichert2804]

He said the last gear of the first gearbox almost reaches 2:1, so its strictly less and the first 12 ratios are unique in the Interval [1,2). Therefore after multiplying with 2^n for the big ratios you'll always end up in the [2^(n-1), 2^n) Intervall for n \in {1,...,5}. Therefore each of the 60 total gear ratios is unique and increasing exactly in the order you described (1,1), ..., (1,12), (2,1), ..., (2,12), ..., (5,1), ..., (5,12).

@@richardbrooksshnee The ranges aren't overlapping at all. The only interesting thing is how close is almost 2:1 to real 2:1 and how are the steps seperated.

[@richardbrooksshnee]

@@mauricereichert2804 yes they are. The operator would be skipping that last gear as x~2 and x2 are close enough to the same that any rpm differences would be negligible from their standpoint and so there is no worthwhile reason for the overlap. You're going to shift to x2. You're ignoring the point and purpose of a gear box. Effectively the same is wasted and is an overlap in range. Damn near the same output to engine rpm & torque. Your "but the numbers are slightly different" is obnoxiously pedantic to the point of counterproductivity and ignorant to the point of a drive train. You can cry technically right all you want.

It's not quite as extreme as a twinstick, but it was certainly a bit of a learning curve.

[@dammityoutube]

Most modern semi transmissions are still 2 transmissions, they just share one case and one "stick". Depending on what transmission you have, it can be a 5+4 with low range on the bottom is a 9 speed. A 5+5 is a straight 10. A 5 speed with a splitter is a super 10. You take a 5+4 and add a splitter to the top 4 speed and you get a 13 speed. 5+5 with a splitter on both the bottom and top 4 is a 18 speed. Plus a whole lot more different combos.

[@can_hauler]

@@dammityoutube your transmission math is a little wrong, the transmissions would be 5+2 for super and regular 10, 5+2+(2(high range only)) for 13, and 5+2+2(not limited) for 18, Yes, I know the numbers don't add up to the actual gear counts, its because of how they label and layout the patterns. 13 and 18 have the same pattern with the difference being the splitter useable in low range, the "missing" 2 gears in a 18 are in the "low" position ( 13 has low (low range)/ high low low - high high low (high range w/ splitter), 18 has the low range split as well. Most drivers only use the "lo" position in the lowest and highest possible ratios (if at all, those gears are extremely low) because the other ratios are barely different, the usual shift method is to go sequential and not use the splitter unless you need to, the splitter basically does 1X/1.5X with X being the gear (1,2,3 ...16,7, etc). 10s will get you there, 13s are better, and 18s are the best. The reason is because every incline has a gear ratio that maximizes speed for current situation (your weight, your engine, % grade, etc) and an 18 has the best chance of getting you as close as possible to it without going "over".

[@stevemccluskey7102]

most gear boxes dont increase speed until the highest gear(s). for example, the standard 5 speed transmissions gear significantly down from gears 1-3, 4th gear is direct drive, and fifth gear is slightly over driven. most transfer cases gear down even more, and the diff gears down for the final drive ratio. most cars engines are spinning roughly 3 times faster than the axle in the highest gear. a better design for this is to either flip the input and output so you're always gearing down, or make the 1:1 gear either 6 or 7 and up or down from there, including the multipliers, which to eliminate doubling gear ratios, should be a 5 speed with 1:4.05, 1:2.05. 1:1, 2.05:1, and 4.05:1 or something similar. that way, gear 30 is 1:1 approximately, and every other gear is higher or lower than the input.

[@stuartdilts2729]

This is exactly the same technique that bicycles with a front and rear derailleur use to give lots of gear ratios.

[@nevernether3368]

I'd be interested in seeing him 3d print a clutch for this. Hook up a motor and shift through them all

[@CaimanAlphaFoxtrotMike]

Hey super cool that you did a multiplier gearbox

[@timesthree5757]

You made a big rig transmission and multi gear splitter.

[@Antichamberteam80110H]

Try using herringbone gears to increase efficiency

[@mx_nana_banana]

shouldn’t the “front” (which is really the back gearbox) gearbox be the other way round?

[@oregonfordguy9812]

if you created a dual shift setup tou can have way more gears. look at the old mack duplex and triplex trans missions.

[@SlendisFi_Universe]

To make them smoother, use syncros

[@ampstudios4169]

Time to put this in a car to break the sound barrier

[@jaylanmcmurtry5317]

Miata owners on their way to fit this in

[@leoshahbazian6830]

You just made a gearbox with a transfer case. Lots of cars have two transmissions like this for 4wd and low gear ratios for high torque/low speed.

[@lrexoticgaming5636]

Are you sure this is 60 different speeds, gear 12 has a 1:2 ratio with a 1x multiplier (1:2 overall). Gear 13 goes back to 1:1 ratio in main box but then uses the x2 multiplier gear which would also make it 1:2 overall. This means that every time you go to a different multiplier and back to gear 1 in the main box, the gear ratio is the same. Another example is with 24th and 25th gear, 24th gear uses 1:2 in the main box and a 2x multiplier in the second box (1:4 overall). 25th gear goes back to a 1:1 on main box but a 4x on the secondary box which will result in the same ratio (1:4 overall). This can also be seen with gear 36 and 37, gear 36 is 1:2 in main box, and 4x multiplier in second box (8:1 overall) and gear 37 uses the 8x multiplier and the 1:1 in the main box (1:8 overall). Otherwise it's very impressive how you got so many gears in such a small package.

[@j.a.r.family2576]

Just found you. Have you built a turbo system for a car like this? Would be super cool to see.

[@DarmiGames]

Now I need to know what the optimal shifting is, to get from lowest speed all the way to highest speed using all the gears

[@SteelJM1]

AH the 60 speed xmission, for when your engine idles at 700rpm and redlines at 800rpm

[@Brooksie997]

Do the amount of cogs on each gear matter? Are they all the same amount? How about the spacing?

[@npsit1]

If you engage multiple gears you can have more gear ratios with fewer parts..

[@justcomments1239]

Could you make a non electric power drill with this?

[@launcesmechanist9578]

Can't help but wonder if this could have any practical applications for vehicles, heavy equipment, construction, etc. It'd be impressive it possible.

[@RixxleSnoops]

heavy machinery already use gearboxes similar to this
