After the difference ΔMRe, the span value in the table is corrected.
ΔMRe = Ke · esv (13)
5.3 The rod diameter DRi and DRe listed in Tables 1 to 28 are determined according to 3.1.1 and 3.2.1. If necessary, make a number on the bar
Plane to avoid contact with the spline trails.
5.4 When the actual selection of the rod diameter and the diameter listed in the standard are different, the maximum distance between the spline rod spacing MRimax and the minimum
MRimin, the minimum value of the spline span distance MRemin and the maximum value MRemax, should be calculated according to the actual rod diameter.
