Dimensioning is carried out using diagram 1 (Sizes 0 – 2) or diagram 2 (Sizes 3 – 5) with “Torque M [Nm]” and “Misalignment [%]”:
- Determining the “Torque M” coordinates:
- Determine the maximum operating torque.
- Multiply the operating torque by the values from the temperature factor table and service factor table (interpolate the interim values).
- Determining the “Misalignment” coordinates:
- Determine the individual shaft misalignments as a percentage, measured using the “permitted shaft misalignments” for the intended coupling size. Example for size 2: 0.2 mm axial displacement equals 25% of the permitted value 0.8 mm.
- Add up the individual percentages. The sum total must be less than 100 percent.
- Enter both determined coordinate values into the respective diagram. The point of intersection must lie below the characteristic curve of the intended coupling size.
- If the point of intersection lies above the characteristic curve,
- select a larger coupling,
- reduce the shaft misalignments or
- contact the manufacturer.
