Hello,
I need to select an appropriate electric motor for a drive mechanism which includes a U-Joint. It's understood that rotational variances occur in U Joints as the angle of the input shaft increases relative to the output shaft. Can someone refresh my memory as this relates to torque? In other words, is there a percentage increase in torque to drive the input shaft as its angle increases to say 15, 30, 45, 90 degrees relative to the output shaft that stays at 0 degrees? If so, what's the percentage increase at each increment - or at least a general rule of thumb?
Many thanks.
Bret
