If you want a good introduction to Lego Technic in general, then I recommend the book "Unofficial LEGO Technic Builder's Guide" (nostarch.com/technicbuilder2). If you want more information about Lego Technic gearboxes in particular, then I recommend looking at videos on KZread or reading some forums. For example: www.eurobricks.com/forum/index.php?/forums/topic/150313-gearbox-collection-thread/ Most of the larger Lego Technic sets include some sort of gearbox, and you can download the instructions for these sets from the Lego website: www.lego.com/en-au/service/buildinginstructions Apart from that, sometimes it is just a matter of getting your hands on some Lego pieces and trying things out.

+Preston Gravy - I'm sorry, I made this gearbox over six years ago, and I haven't made instructions for it in all that time. While I won't say that I will never make instructions for it, I won't be making them anytime soon. This gearbox is a proof-of-concept, and as such it demonstrates an interesting mechanism, but ultimately I consider it a failure. Under load, the gears start to slip and grind. I don't want you (or others) to ruin your Lego gears. I would rather that you take my original concept and adapt it to your needs to make your own gearbox. I made a much better gearbox (which I did make plans for) here: kzread.info/dash/bejne/dXZ2zsilncyaYbg.html

@slfroden

This gearbox has two distinct outputs. The first output has three possible speeds, while the second output has one speed when engaged. Hence I have labelled it a four speed gearbox. This is not the same as, for example, a car gearbox that only has one output. The second output just happens to rotate in the opposite direction to the first output, but this could easily be changed with a few more gears if required. This is just a proof-of-concept, and many elements could be changed, including making the motor that changes the gears go faster.

Very well designed

There are many ways to make a Lego gearbox. Which one is better? That will depend on your criteria for rating the gearboxes. Is it better to have more gears? Less gears? Close ratio between gears? Compact size? Gears that don't skip or grind? Sequential? Automatic? Continuously variable? Can handle high torque? Etc.

During the first half of the video, the shifter is able to slide along two axles freely. During the second half of the video, the shifter still slides along those sames axles, but the fixed 8-tooth gear at the top of the shifter mates with the worm gear which is rotated by the motor on the left. The motor is controlled remotely.

with real pto's you can still move while the pto is running.

You should make a huge flywheel for it

Very clever.

@slfroden

6 жыл бұрын

A 'transmission' has different meanings depending on where you live. In the US, the 'transmission' is just the gearbox, and the clutch is separate from the gearbox. Therefore the gearbox is, by definition, clutchless. In the UK, the 'transmission' refers to the whole drivetrain, including the gearbox and clutch (if present). The mechanism in this video only shows a gearbox, and therefore it is clutchless, regardless of which definition you use for 'transmission'. However, this gearbox is meant to be used in a larger model, which could include a clutch.

Great work! one of the best lego gearboxes, but i think you have to choose an other gear ratio: it has to shift faster;-)

+WEBERLIN 04 - You can use a diving ring to switch between two gears for your first output - just gear one of them up/down. For the second output, add another gearset from your input, and use gears (eg. 8 > 24) to get a lower gear ratio.

@leoweber3629

Sorry I didn't explain this better, I am building a tractor model, and tractors have a utility type of output that connects through a PTO shaft to another piece of machinery. (Mower,planter, woodchipper, etc) and this is located above the rear axle just behind a 3-point hitch. The PTO needs to turn slightly slower so the motor doesn't burn out. I need to be able to engage and disengage the rear axle. I also need to be able to control the PTO even if the wheels are being driven or not. the tires need to be controllable in two speeds, HI-LO low is at most, 1/2 a foot a second on 3in tires, and High is 1-1&1/2 ft a second. I am using parts from two sets, 42042 (crawler crane) and 42053, (Volvo wheeled excavator(not real name)

@slfroden

+WEBERLIN 04 - The setup I described should still work. The diving ring has 3 positions, so you can drive the rear axle in low gear, neutral, or high gear. The PTO uses the other gearset which spins whenever the input is spinning. Then you just have to play with the gear ratios to get the speeds that you want.

If you ran a chain or idler gears between the forward and reverse shafts would it bind up when you put power to the input shaft or would it spin freely until the gear is selected?

@slfroden

5 жыл бұрын

@Josh Picard - The only reason for 'reverse shaft' is because I wanted a design for a gearbox with 3 gears and one PTO gear. You could remove the reverse shaft/PTO, and extend the gearbox to have more/less gears as needed. If you linked the forward and reverse shafts together, then the speed of the two shafts will also be linked - no necessarily the same speed as each other nor the same direction, but linked none the less. Since this gearbox can only engage either the forward shaft or the back shaft at a single time, they will not bind when linked. If no gear is selected (the small dead-spot between gears), then both of the shafts can spin freely, but, as they are linked, spinning one shaft freely will also cause the other shaft to spin also. Of course, if you change gears very quickly, there will be rotating gears/axles within the mechanism which are temporarily no longer connected to the input, and as you change to another gear and this may cause some stress on those components and may cause binding.

Very nice.
