great video. but why does there appear to be so much backlash in the gear mesh? is there a more idealized way to space out the gear teeth to eliminate this or is that gap necessary in some way?

You are a legend! Thank you! Solid Works 2012 SP5 on windows 11.

0:30 According your first video ..Design 1 -> you have named as Pitch circle not base!

Can you provide autocad file please

Great content

wonderful explanation

Thanks brother it works🎉🎉🎉🥰

So is the pressure angle calculated or just chosen? The angle is needed before the diameter of the base circle is calculated, right? This is the part that is confusing to me.

U deserve a like and subscribe!!

Solidworks sucks. So much wasted time doing simple things.

Amazing! I was looking for it for so long. Very thank you!

Exceptional clarity! Thank you very much.

Thank you, Sir!

Thank you for this tutorial, it was well planed out and straightforward. I liked it particularly because it helped me join the concept of making an involute for a circle and then using it to design the gear teeth. I will definitely recommend this vid to my friends and comeback latter to watch it again.

I need to calculate the time taken by the torsional spring to restore back to original position ie released from 90 degree Can you please suggest any books for getting information regarding torsional springs.

This is very helpful because there is so much misinformation about drawing involute gears on the internet, but I do have a question. To get the circular pitch, you divide the base circle circumference by the number of teeth as you state. But you then add that it can be found by multiplying the module by PI, which gives a different answer. Or am I wrong?

Please video upload inner gear teeth with pin dia.

Hello sir good morning

How do I contact someone for help with torsion spring on a prototype?

can someone reach regarding torsion spring help. Im working with a protoype and will pay for assistance with this.

Sir g iski source file hi send kerd dein kindly!!!!!

Hello! Great video though I have a question concerning the formular you used for the CIRCULAR PITCH. In your other video th-cam.com/video/IBcGLpQnfYk/w-d-xo.html at 4:17 used defined the CIRCULAR PITCH formular as Module*Pi. But in this video at 18:14 you define the CIRCULAR PITCH as 360 / Number of Teeth, kindly explain. I am a bit confused, thank you.

Do you write a book, I have great interest to buy one!

Very good

1/4-28 UNF

F1 = 2.91N , Deflection-1 = 6.56mm ( 2 formulas where conflict). F1 = G x d4 x df1 / 8xD3 x Na , df1 = 8 x F x D3 x Na / d4 x G

So how do you find the major diameter of a 1/2" x 20 unf 2B no go plug gauge?

love you

I have a hard time understanding why we need 6 pitches, as there are in fact only three different. Why twice Pitch X = Pitch Y and so on?

worked for SW2017 SP05 !

what is reference book or document for formula used in this video ?

Hello, with tensile limit do you refer to tensile strength?

it workssss thankyouuu❤❤❤

Hi Great video, really useful. Do you have a video explaining the terms you've used in the video especially the module? For example i'm wondering if I can create a gear where one of the variables is the diameter of the desired gear.

The use of 'k' has an error.

Great tutorial! One issue I had was during the 'Convert Entities' step at 19:26 it seems like that curve did not maintain its reference to the global variables. As a result, I had issues when trying to change the scale of the gear. Fortunately, it was a pretty easy fix by dimensioning the curves separately. I'm not sure if I did something wrong here, but I figured I would share this anyway in case it could help anyone :)

Excellent series. I am not an engineer but followed up to 6.20 Rate equation, got lost with units. I assume D and d are mm? but what units for E?

Hey good content man, if you see at 5:40 the formula of Addendum circle as u mentioned is {Pitch circle + (Module * 2)} As per your values this should be 64mm, but u have 104mm, is it right? or am I wrong, can you clarify that part?

Is it geometrically correct to apply the rack tooth to internal gear. Won't be there any collision?

I need examples because I am finding contradicting information in the tables. (or not looking at the correct table). For an example if I need to know what the Minor diameter max and min value are for a M20X2.5 6H. I found out that the value is 17.294 but I got a table that class 6 is 450 um (BS ISO 965) and H is 0/+0.042 so is the min max value 17.294 to 17.744 or 17.294 to 17.474 or 17.294 to 17.516 Witch is all wird because the drill in 17.5 before threading so anything under this is irrelevant.

took me a week to find a right video whose actually use the equation and drawing techniques right. thank you

amazing video, thank you

When I was a line inspector many years ago, at a thread rolling screwing company, I noticed that when a metric or UNC tools were damaged they stopped producing commercial threads. However when the BSW Thread Rolling Dies, looked stuffed, they still produced sellable threads. Just my observation.

at 5:48 on the video as you click the OK box the base circle dimension can be seen changing as the formula applies. When examining the dimensions in the evaluate to column the only dimension that is correct is the pitch circle, the other 4 are incorrect. Advance to 5:55 in the video your sketch dimensions are all correct. Is that caused by Solidworks being slow at math or was it problems with the formulas and was edited out. That page you inserted the formula's on led to much confusion.

Hi there, loving this, great explanation! But I seem to have got stuck on calculating the base circle. The equation needs the angle interaction, but that is calculated by using the base circle… Do i just choose a number between 15 and 25 degrees?

28:06 I believe the tooth profile of the rack is still technically an involute, it's just that the involute of a circular curve with infinitely large radius (i.e. a straight line) is itself a straight line. Certainly the curvature of an involute of a circle tends towards zero as the circle radius tends towards infinity.

at 00:45 you talk bout base cirkel bu according to your part one, the drawing is showing that the circel you makred as base circle is the "pitch circle" wich one is the right circle name?
