How to fix length of a universal shaft spline?

[farzadinjast]

Hi friends,

I am considering the use of universal shaft between two parallel shafts. The casings of the input and output are not precisely built and I need to adjust the length of the universal shaft to install them. The spline shaft solve this problem but I may have trouble with the vibration. The Input has naturally high level of vibration that should be damped as much as possible and prevented from output. I am worry about float spline and its axial vibration that may cause noise or damage. Is there any way to fix the axial position of spline reliably after the length adjustment? I think it can eliminate any axial vibrations.

Please note that the shaft must work in high temperature (300 C).

Thank you in advance.

Is there any experience with universal shaft?

"Is there any experience with universal shaft?"

Aside from the 300 C, many millions of US and foreign automobiles over the last 80 years or so.

Most had splines and ran successfully for 1000s of hours, from zero to over 3000 rpm even while transmitting hundreds of horsepower.

Yes, sometimes getting splines to slide under power without binding is tricky.

This is one of the best 100 US bucks I ever spent.
