Nice work on the gearbox. One thing is never wear gloves when operating rotating assemblies like lathes, mills, drill press. It's easy to forget that you are wearing gloves and can get your hand, fingers pulled into the rotating parts of the machine. I had my index finger twisted off my hand. Keep up the good work.

[@yukarnahayilador2814]

ฟฟ

[@CMAenergy]

Use latex gloves from walmart, they tear easily Definitely never use any other kind of glove working with any lathe or mill

[@evinsteven13]

Wow, this is an awesome build! Personally, I wouldn't trust my life with one 1/4" keyway for the main gear, I would use a splined shaft, but still, great work!

[@ultralighthelicopter]

Thanks Diesel Zuk. Good point... I keep a splined shaft in my mind for a update...

Make sure of your materials correct heat treatment and hardware in that rotor box. Also need to check for run out in the bearings and shaft and gear mesh. This is from 35 years as an aerospace machinist and assembler. Always remember it is the little things that can bring you down.

[@bartdereu]

this seems like a gearbox that is going to fail allot faster then he wanted. It scares me watching this. There's too much play between the teeth, how are the materials hardened? Things are never as easy as they seem.

Nice but, Why not fill the gearbox with liquid oil? this would prevent the gearbox from overheating !!

[@kanartech]

Iits also a nice idea but it does not really matter depend on the rpm

[@tunercamp]

완성작이 기대됩니다

[@800mmTelescopeProject]

Nicely executed! One remark though - it's an engineering misconception that key slots carry torque. They don't or to a minimal extent. The big gear should be press-fit in order to generate enough friction to carry torque without slippage. TBH I don't know the level of torque you are transmitting but that gear is beefy. The smaller gear instead at least is loaded axially and can cope with the smaller torque. My two cents...

[@ultralighthelicopter]

Thanks... Yes i get your point i will do a upgrade on the gearbox regarding torque slippage... stay tuned....

Допускаешь ошибки при запресовке подшипников!!!!

[@Raul28153]

advice from an old machinery builder. Lube your press fits before assembly. It prevents galling. I am a little curious why you chose not to use sealed permanently lubricated bearings. Is that really all the lube those gears will get, that little bit you applied with a brush? I'm also a little curious about the gear engagement. It seems to be shallow by about 0.030"

[@Michigan_Tactical]

I was surprised he lubed the gears but didn't seem to pack the bearings with grease.

[@Raul28153]

@@Michigan_Tactical He does a few things that leave me wondering. Like welding with no fillet.

[@Michigan_Tactical]

@@Raul28153 I wondered about that myself.

[@nickab9719]

It's better to have the bearing in a plastic bag when you put it in the freezer. Still amazing work

[@ultralighthelicopter]

I agree Nicka B... And thank you for the support :-)

[@karlalton3170]

Does the gear box not require more grease than that in it dude ? or would it be better with oil seals fitted and gear oil in it ? Just asking 😁😁🤘🤘

[@ultralighthelicopter]

Yes i will probably update to use gear oil in it...

[@SamSam-xf3iu]

Double the bearings on pinion.

[@ChetRosson-l6l]

You need to use tapered roller bearings

[@sakibloser818]

Thank you brother for giving us your 14 mountaineering in 13 days

[@ultralighthelicopter]

You are welcome Sakib...

[@lowtus7]

How are you lubricating the gearbox?

[@suriyasripan3820]

If you design to fill oil gear inside that would be great , but so challenge jobs anyway.

[@bekasbekas1]

Very soft shafts, need surface hardening

[@cliffcampbell8827]

You could always use a few of those CO2 cartridges for a quicker and smaller metal shrinking.

[@tomf3150]

Wow, a gearbox...

[@chhatrsingh9062]

ट्रेन की लंबाई और चौड़ाई

[@WeTrudgeOn]

I think that gearbox is going to be problematic. Almost all enclosed gearboxes that operate at that kind of speed are in an oil bath they are not just dabbed with a little grease. I'm pretty sure that is why the main reductions are done with belts on the Mosquito helis, this is a tried and very successfully proven design. It is also far more forgiving of slight misalignment than gear drives are. I plan on building the Furia heli but it will have six groove Vee belt pulleys instead of the main gearbox.

[@ultralighthelicopter]

I will do a upgrade on it. I missed the point where the original plans for the furia recommend to use oil in the gearbox, but for me i will prefer oil . I like the mosquito design with the belts too, but as i stick with the furia plans i build it this way... and hopefully improving.... All the best for your furia build, i like to see some content in the future...

[@christiansprojects-cgmanuf1426]

What a great project! But I have one question: Why do you use open bearings? Wouldn‘t shielded or sealed ones be much safer?

[@jeanphilippepoirier6130]

The gears are inside an enclosed housing. It is best to lubricate the bearings at the same time as the gear mesh. The questions is how the gear mesh is lubricated. We see some grease is applied during assembly. This is no where sufficient lubrication for operation. I strongly recommend oil lubrication. You will need an oil drain port, oil level port, and oil filler port. The oil filler port can be used to fit a breather. Not sure what will be the operating RPM. At very high RPM, it is common to have pressure lubrication over the gear mesh.

[@brianb-p6586]

@@jeanphilippepoirier6130 helicopter rotors run at relatively low speed due to the large rotor diameter. I don't know the speed of this one, but under 500 RPM is likely.

[@hots2215]

one question you know that when you make lift your props like to life up your main shaft up to lift you up this up force will destroy your normal type ball bearing... you should use some type of bearing that can handle the force in that axis as well did you?

[@ultralighthelicopter]

hy Hots 2 I will do a update on the gearbox bevore the first flight... stay tuned

[@TheMarciotec]

Congratulations! I am impressed by your whim. Please continue with the videos.

[@TuberEver]

🤞🤞🤞

[@Stubytube]

Beautiful work, very well accomplished, ask what is the relationship between the pinion and the crown, so you can see at first glance it would be 7: 1 or less. I didn't like the sound of the pinion bearing very much, sorry. greetings and keep it up

[@ultralighthelicopter]

Thank you! The relationship of the gears is around 4:1 (95 Teeth to 23 Teeth)

[@brianb-p6586]

The small gear is a pinion, but the large gear is not a crown.

[@mindmakes003]

Great work! 😊 When your work going to complete?

[@1marcos55]

you have to change or add a top bearing to a thrust bearing because that bearing you used is not recommended for this type of load

[@ultralighthelicopter]

Hy marco. What bearings would you recommend?

[@26mridul]

balancing with those cotter pins isn't going to be a problem?

[@chrisretired5379]

Thank you for great video ! Did I miss the gear oil fill hole ?

[@ultralighthelicopter]

thanks sir im glad you like my video. I do a update video to use oil in the gearbox before first flight. I wish a good weekend...

[@kopitothai8163]

How about gear ratio.? Perfect work

[@ultralighthelicopter]

kopito thai thank you. The Pinion has 23 teeth, Main Gear 95 teeth so its about 1:4 i guess...

[@tomthompson7400]

great job , what make is that folder , it looks super handy.

[@SodiumInteresting]

wouldn't it be lighter to weld even if it meant cutting through those welds to access later

[@Raul28153]

That' all the lube you are using? I should think you'd want shaft seals, gaskets, and a decent volume of oil. And the bearings. You are not using permanently lubricated sealed? How will you lube them in use?

[@ultralighthelicopter]

Raul McCai i will do a upgrade to use oil in it, thanks for your constructive comment.
