How many degree for alignment cardan shaft?

Answer 1

Depending of the speed and also the technology of the cardan.

Generally, you have to build with a 3° angle approximatly.

The reason is to avoid to have the same needle in contact with the force.

Like that, you spread the force on twice the angle installed.

In industrial shaft Spicer GWB, the construction make the needles turn without rolling, thanks to a ring.

I want to precise that the 3° angle is just an indicated value, not a close value (You are not obliged to build this angle with a laser alignement! If it is 3,01° or 3,2 or 3,9 OK.
