I actually understand what's going on physically/conceptually so much more by watching this videos, thank you a million times over!

[@sarahwagner9745]

sooo helpful. Senior ME student and you're helping me understand my Machine Design 2 class SO MUCH BETTER.

[@LessBoringLectures]

Fantastic!

[@danese1636]

Same

[@mehmetfurkanceylan]

This video helped so much on my Mechanical Design 2 term project. Appreciate the clear explanation!

[@karynthurston4304]

This is fantastic! Very thorough.

[@LessBoringLectures]

Much appreciated!

[@CrazyHostelers]

These are gems! Loving it😍😍

[@localboys7449]

the diagrams are extremely helpful - thank you so much

[@karthikprasadk8001]

Thank you so much... You have cleared the confusion I had.

[@anilbhusal2914]

Great Video on Helical Gear!

[@nicolascaleroarteaga4461]

Bro
I love your quick videos!
So clear and quick!
Thanks a lot🫶🏽💪🏽

[@sagargeetadarshan5182]

Amazing OUTSTANDING lecture ❤️❤️❤️💯💯💯💯

[@oneofyk]

this was really good - thanks

[@ratherrelatablemantisshrim2409]

great video! nice work.

[@BarbosaCarlosNuno]

Top information. Thank you.

[@prathameshsundaram7509]

Can't stop watching! They're great revisions and I always find something new or extra.

[@LessBoringLectures]

Thanks! Please share!

[@prathameshsundaram7509]

@@LessBoringLectures - Always do!

[@CrazyHostelers]

same here!

[@amiotti_]

Excelent video. Do you have a lecture about forces on helix bebel gears? A mixture of both explanations youve made on this video

[@javiermartinez6118]

Excelente video

[@AKASHKULDEEPAGARWAL]

Hi...Very nice video...can you share some info on torque transmitted to another shaft in case of helical gears

[@zeyadabdelsattarahmed6613]

thank you :D

[@AlessandroEren]

super goood!
How about a video talink about the virtual pitch radius or equivalent number of teeth N/cos^3(phi) and the osculatoring circle

[@abdulmoiz918]

MashaAllah Bro Nice

[@tuqam7171]

thank you for realll!

[@LessBoringLectures]

No problem!!

[@KG-nz5fv]

Do you have any resources to understand crown/face gears?

[@bernardmeyer4959]

Is it possible to upload the pdf so we can print it and study from it

[@MinhyeongLee-qv8wv]

D1 and D2, are they the outer diameter of the gears?

[@more2much696]

for the ex : why not use 1 thrust bearing that's what they do in Shigley textbook?

[@indrakumartak9865]

Sir, I have a doubt. How can axial thrust be distributed among the bearings equally?

[@LessBoringLectures]

They are usually not. This is more of a hypothetical assumption to understand/explain a concept. It CAN be done, but usually only one of the bearings takes the entire axial load.

[@indrakumartak9865]

@@LessBoringLectures so sir, how can I measure axial thrust on the bearings if I make this helical gear model and keeping in mind that, axial thrust is not equally distributed among bearings?

[@LessBoringLectures]

Then all the axial thrust value is equal to the axial force on the bearing the IS in fact counteracting the thrust. No calculations are needed in that case.

[@jaisudhikshs7503]

How to find the direction of axial force

[@azeez6081]

bro where is the solidworks model file link ?

[@md.arrahmandip7638]

Where is the solidworks file?

[@berkayozfidan5066]

couldn't find video about interference (smallest number of teeth which will not have interference formula etc.)

[@aygunagayeva6857]

The figure shows a double-reduction helical gearset. Pinion 2 is the driver, and it
receives a torque of 2120 lbf. in from its shaft in the direction shown. Pinion 2 has
a normal diametral pitch of 8 teeth/in, 14 teeth, and a normal pressure angle of 20
and is cut right-handed with a helix angle of 30°. The mating gear 3 on shaft b
has 36 teeth. Gear 4, which is the driver for the second pair of gears in the train,
has a normal diametral pitch of 5 teeth/in, 15 teeth, and a normal pressure angle of
20° and is cut left-handed with a helix angle of 15°. Mating gear 5 has 54 teeth.
Find the magnitude and direction of the force exerted by all of the bearings on
shaft a, b and the c, if bearings B, C and E can take only a radial load while
bearings A, D and F are mounted to take both radial and thrust loads. The life goal
is 25 kh, with a reliability factor for the ensemble of all four bearings to equal or
exceed 96%. The Weibull parameters are x0= 0.02, (θ- x0)=4.439, and b= 1.483.
The efficiency of the system is 90%.
(a) Select the roller bearing for location B and C and ball bearing for E.
(b) Select the ball bearing (angular contact) for location A and D assuming the
inner ring rotates and for F assuming the outer ring rotates.
***Can you help me to solve this problem?***
