? Steering U - joint PHASING ?

+ RELATIONSHIP BETWEEN U_JOINTS ON A SHAFT - (not angle of shaft). +

:smash:

In researching Steering Shaft u-joint phasing I find different thoughts !

Anyone comment about what is best ------ 90 deg / 45 deg / 0 deg / DOESN'T MUCH MATTER deg / or ????

I have seen all of the above --- I assume not being a high speed rotating shaft like a drive shaft it doesn't much matter ------ but any comments would be beneficial .

It depends on the manufacturer, but about the most angle you can get from a borgeson single without physically binding the yokes is 35*, if you use their high angle u joint.
Unisteer will go up to about 40*.

Speed is not really a consideration in a steering shaft, but binding the yokes is where your problem will occur.

Flaming river is somewhere in that range as well.

Anything more than 35 or 40 degrees and you need to use a double U joint.

Phasing should be straight in alignment, although if you have a binding problem you can put the joint 20* off in phase from any other on the same shaft and lessen the bind.


Do a search here for steering U joint, and you will see a bunch of discussions about phasing, which U joint will operate at what angle, etc.

Hope this helps,
Mikey
