Abstract:
The present disclosure provides a hollow drive shaft which may include a hollow steel pipe, a mandrel set at the center of the hollow steel pipe in an axially direction, and a spiral rib plate set between the hollow steel pipe and the mandrel. The major diameter end surface of the spiral rib plate is spirally welded on the inner diameter surface of the wall of the hollow steel pipe. The minor diameter end surface of the spiral rib plate is welded on the outer diameter surface of the mandrel. The helix angle of the spiral rib plate is 10 to 45 degrees. The helical direction of the spiral rib plate is opposite to the delivery direction of a working torque M.
