How to calculate the shaft diameter from the torque?
From this maximum operating torque, we can find the shaft diameter with the above equation. 2070.06 x 10 3 N-mm = (70Mpa (N-mm 2) x π x d 3 )16. d 3 = 150687.075 mm. d = 53.19 mm. The required shaft diameter will be a 53 mm shaft. Here is an online calculator that Helps you Calculate the shaft diameter. Try it, it will be fun 🙂.
