Driveshaft Angles

Interesting video demonstrating driveshaft operating angles.

That is a good video, I've seen it several times over the years. It's interesting to see the driveshaft turns faster over the top angle than it does underneath.

We have a competitor in my professional world that had a machine using that concept. They had an electric motor with a u-joint on a 45 degree angle driving a pan for conveying potato chips. The pan would move forward at a slow velocity and when the u-joint went over center it caused the pan to return with a higher velocity so the product was shuffled along the pan. Good concept but a poor application of u-joints, lots of parts breakage.

Mr. Mike,

Thanks For Testing My Memory!

I remember posting that same video way, way back in 2017 and is in the link below:

LOL...explain your random font size, Steve. :) I can never figure it out when I read your posts. Every line of your posts are a different font size. I've never seen such a prodigious user of the font formatting available here on the forum. Hahah!

Font size shifts often makes it easier for me to read what I wrote.

I used to be a trainer at Dana and when we would do that demonstration in person, people could not believe the impact of angles. At slow speed, it doesn't look like much, but at high speed, the torsional vibrations will destroy expensive transmissions in no time at all. Another thing to note is that if you separate the two halves of a driveshaft, mark them before separation. If you don't, you will likely pick up a vibration due to the shaft not being in the same alignment as when balanced.
