Spur Gear Force Analysis: Tangential and Radial Load

[@allankafue455]

Why are the two torques in the same direction ,

[@engineeringvision]

Which gear are you referring to?

[@allankafue455]

I mean why is tb3 and tb2 the same

[@engineeringvision]

Those are the torques the shafts are acting in their corresponding gear. The equilibrium of moment on each gear determines the direction of reaction torque. The shaft torque resists the torque generated by the tangential component on the gear.

Great work, thank you!

Thank you this video really helped me.

You are welcome! Which college do you go to?

[@Azch20]

Did you have explain the gear strees and stress analysis of gears? . What an amazing instructor 👍

[@engineeringvision]

Thank you for your comments, yes, stress analysis will be posted as well

@@engineeringvision Doctor Sanei if we have double stage helical gears , speed reducer If gear 23 have tangential force = 911 N Should the gear 45 have the same value of tangential force? Same as with diameters, lewis equation and AGMA

[@calemvlog]

hello sir, i am having a system 3 gears with different angle (76 and 29) can you help me out please. Thank you very much.

[@engineeringvision]

You need to post a link to the problem so I can look at it

This is my problem, if possible you can write on the link so i can understand easily. Once again thank you very much !!

Is it that idler gear always has zero net torque acting on it for simple gear train?

[@engineeringvision]

If it sits on an idler shaft, idler shaft Carrie’s no torque, it is not a driver that takes the power from the engine and not the out pit shaft that takes the load
