This is part 11 of the EXPERIMENTAL HELICOPTER BUILD SERIES
#buildseries
See how i do a update on the Main Gearbox here: ruclips.net/video/whfStV1Pk_g/видео.html
Following this experimental gear box how it works nice sharing goodluck
You are one of the few that knows how to install a bearing.👍
Спасибо за полезное и интересное видео .Ok!
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.
ฟฟ
Use latex gloves from walmart, they tear easily
Definitely never use any other kind of glove working with any lathe or mill
Great gearbox but for a helicopter this scares me.
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!
Thanks Diesel Zuk. Good point... I keep a splined shaft in my mind for a update...
Jesus!!!!! Man schrumpft doch kein Lager ein wer hat dir das den beigebracht
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.
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.
Fantastic tolerances on those bearings
Tenks my prenk video is good
Nao é só querer fazer , tem que saber fazer. Parabéns pela iniciativa .
Clean work very interesting I'm waiting to see full helicopter ready to fly
Love from Malaysia
Thank you :-)
Kerja yg bagus 👍👍👍
I like your video, the manufacturing technique is very good
Nice but, Why not fill the gearbox with liquid oil? this would prevent the gearbox from overheating !!
Iits also a nice idea but it does not really matter depend on the rpm
Best of the best
Good jobs and perfect matrial
Very nice work. you are certainly putting some hours in on this project. look froward to the next video.
Thank you !
Hi
Very nice
You need to use tapered roller bearings
Interesting design! Good luck!
Excellent technique
완성작이 기대됩니다
Блин, молодец! Хороший инструмент, прямые руки, светлая голова!
can you share the PCD calculation for the main gear box,, i failed to make a smooth gear box ,, i think the pcd of the both shaft are not properly placed on housing .. Or the grears engagement is tight .. plz share if you have ..
It's better to have the bearing in a plastic bag when you put it in the freezer. Still amazing work
I agree Nicka B... And thank you for the support :-)
Nice
There's no way i'd fly a helicopter with a homebuild gearbox.
amazing tecnick...good job👍👍👍 you'r my teacher 😀😀😀
Thank you robi tenar
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...
Thanks... Yes i get your point i will do a upgrade on the gearbox regarding torque slippage... stay tuned....
Very good video
Thanks for this video
😍😍😍
Your welcome :-)
If you design to fill oil gear inside that would be great , but so challenge jobs anyway.
really nice work... glad to see you are getting some good advice .. imho
thanks so much
Очень круто!
"Wow" clean and beautiful ..
Thank you!
Допускаешь ошибки при запресовке подшипников!!!!
Sir every time you are amazing us with your work.love from india
Thanks for your support Sir... love to india...
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 😁😁🤘🤘
Yes i will probably update to use gear oil in it...
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.
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...
It's looking great! Congrats! 👏
Thank you! Im glad you like it...
@@ultralighthelicopter wheres the sealant
Good job bro..tanks
Thank you Heri Yadi
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
Hy marco. What bearings would you recommend?
very cool , bravoooooooooooooooo
Too much good! 😁
Thanks John Smith :-)
Great work
im jealous youre router cuts true circles, mine cuts whatever it thinks a circle is , then i have to ream the hole afterwards
Great work.Very inspiring.
Thank you :-)
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
Thank you! The relationship of the gears is around 4:1 (95 Teeth to 23 Teeth)
The small gear is a pinion, but the large gear is not a crown.
Congratulations! I am impressed by your whim. Please continue with the videos.
What a great project! But I have one question: Why do you use open bearings? Wouldn‘t shielded or sealed ones be much safer?
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.
@@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.
Yes i like it. The gear terisolasi no penbel
Thank you Dery i will do a update on this in the future...
@@ultralighthelicopter yes i like the gearbox
This is soooo pleasant
Thank you brother for giving us your 14 mountaineering in 13 days
You are welcome Sakib...
Amazing job
Thank you!
Very soft shafts, need surface hardening
woow best
nice work
Abdo Eshwehdi thank you, i really appreciate it!
merci bien
Vc e um gênio cara👏👏
Amazing 👏..Keep it up..
trop super cette vidéo
Thank you christian kammogne.
ASALAM-ALAYKUM 😯😯😯👍👍👍🇺🇿
love it
Thanks Elias :-)
Double the bearings on pinion.
INCREIBLE!! MUY BUENO!
waiting for next part
Масло смазочное будет выгонять на раз два.если только не проточная система
Nice work man!!
Thank you! :-)
hi bro ur video are awesome please make it longer
You could always use a few of those CO2 cartridges for a quicker and smaller metal shrinking.
Bravo you are very good!
Thank you Serif
Крышка малой шестерни, можно было установить туда подшипник. Дополнительная защита от вибраций и разрушения
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"
I was surprised he lubed the gears but didn't seem to pack the bearings with grease.
@@Michigan_Tactical He does a few things that leave me wondering. Like welding with no fillet.
@@Raul28153 I wondered about that myself.
My hero
Wow, a gearbox...
Wonderful work. Fascinating!
Thank you! Im glad you like it.
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?
hy Hots 2 I will do a update on the gearbox bevore the first flight... stay tuned
What country are you from my friend? do you have an email address.. I want to chat with you, thank you
how do you plan to lubricate the bearings and gears?
How are you lubricating the gearbox?
Great work. i want to be your student
Thank you, im glad you liked my video :-)
balancing with those cotter pins isn't going to be a problem?
👍🏻👍🏻👍🏻
great job , what make is that folder , it looks super handy.
Thank you for great video ! Did I miss the gear oil fill hole ?
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...
Nice video. Is that an optima lathe? what model lathe is it?
Surly that gear box needs to be oil filled?
Great work! 😊 When your work going to complete?
Waouww... Impressive work !
What's lubricating the main bearings?
Llllllllllllllllll
@@user-qg4jq4qb3z oil
Good
Thanks Parminder Singh!
ល្អ
Всё вроде здоровско и чётенько, но на 6.27 подшипничек в помоечку не просится, судя по перебору шаров?
wouldn't it be lighter to weld even if it meant cutting through those welds to access later
ट्रेन की लंबाई और चौड़ाई
How about gear ratio.? Perfect work
kopito thai thank you. The Pinion has 23 teeth, Main Gear 95 teeth so its about 1:4 i guess...
You really never showed much for lubrication in that a gear box, and did not do any follow up on those 3 filed 1/2 holes on the cover plate
I noticed the unused notches. My guess it that they're just for prying this cover out.
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?
Raul McCai i will do a upgrade to use oil in it, thanks for your constructive comment.
