MECHANICAL CHARACTERIZATION OF FLEXIBLE SHAFTS


Flexible shafts are mechanical elements which are subject to torque and undergo a rotational elastic deformation. Considering a single flexible shaft, the equal and opposite torques which are applied at each extremity cause a relative rotation of the various sections which is proportional to the distance between the sections. The relation between Applied Torque T [Nm] and Twist Angle of the extremities φ [°] is a function of three parameters as follows: 

● Torsional Rigidity k [103Nm/°] which depends on the section diameter and its construction characteristics
● Length of the shaft L [mm]
● Rotation Direction r (dimensionless parameter which characterizes the asymmetric behavior of the shaft) 

Parameter r is equal to 1 when the shaft is loaded according to the winding direction of the spiral; when loaded in the opposite direction, r < 1 as indicated in the following table:

BENDING EFFICIENCY  

The above shows a qualitative-quantitative curve of the efficiency of the flexible shaft as a function of the bending radius. 
For configurations which are almost in a straight line, the efficiency is equal to the maximum value 0.9. 
The efficiency is nearly constant for high values of the bending radius and decreases rapidly down to 0.2 as the minimum bending radius is approached.

- To identify the most suitable flexible shaft for your requirements, refer to the values in the table. If the real loads and efficiency are very close to the table values, contact the technical department.
- To choose the most suitable flexibel shaft, we advise to consult the figures, tables, and the technical data shown in the “General Information” of this site.
- All tables show linear measurements expressed in <mm>, unless otherwise specified. All forces, efficiency and the loads are expressed in <N or Nm> (10 N ≅ 1 kg or 10Nm ≅ 1Kgm) unless otherwise specified.
