No, it's actually not angular acceleration, it's angular velocity.
Constant rotation = constant angular velocity = zero angular acceleration.
The vector of angular velocity is parallel to the axis of rotation, and is
constant throughout the rotation. There is linear acceleration as you
describe, but we're discussing angular.
Now, Einstein, enough pedantics - go build something. ;)
