Abstract
A flexible drive shaft test arrangement includes a drive end piece arranged along a rotation axis, a driven end piece axially offset from the drive end piece along the rotation axis, and a shell. The shell connects the drive end piece to the driven end piece. The drive end piece end is offset in rotation about the driven end piece to internally load a flexible drive shaft disposed within the shell with torsion. Test stands and methods for testing flexible drive shafts are also disclosed.

A method of testing a flexible drive shaft, comprising:
- at a test arrangement for a flexible drive shaft having a drive end piece arranged along a rotation axis, a driven end piece axially offset from the drive end piece along the rotation axis, and a shell connecting the drive end piece to the driven end piece,
- offsetting the drive end piece relative to the driven end piece about the rotation axis to apply torsion to a flexible drive shaft disposed within the shell;
- and
- fixing the drive end piece in rotation about the rotation axis relative to the driven end piece to retain the applied torsion in the flexible drive shaft.
