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.
Claims19
A flexible drive shaft test arrangement, comprising:
- 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, and
- a flexible drive shaft engaged between the drive end piece and the driven end piece with the shell internally loading the flexible shaft in torsion.
A flexible drive shaft test arrangement, comprising:
- 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, the drive end piece offset in rotation about the driven end piece to internally load a flexible drive shaft disposed within the shell with torsion, wherein the drive end piece includes a flexible member configured to connect to the shell.
A flexible drive shaft test arrangement, comprising:
- 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, the drive end piece offset in rotation about the driven end piece to internally load a flexible drive shaft disposed within the shell with torsion, wherein the drive end piece includes a drive flange, the drive flange axially offset from an axial end of the shell.
A flexible drive shaft test arrangement, comprising:
- 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, the drive end piece offset in rotation about the driven end piece to internally load a flexible drive shaft disposed within the shell with torsion, wherein the drive end piece includes a spline.
A flexible drive shaft test arrangement, comprising:
- 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, the drive end piece offset in rotation about the driven end piece to internally load a flexible drive shaft disposed within the shell with torsion, further comprising a flexible drive shaft arranged along the rotation axis and within the shell.
A method of testing a flexible drive shaft, comprising:
- offsetting a drive end piece relative to a driven end piece about the rotation axis to apply torsion to a flexible drive shaft disposed within a shell that connects to the drive and piece and the driven end piece;
- 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.
