Flexible Shaft Torsion Testing Machine
Category：Torsion Testing Machine
Introduction
The Flexible Shaft Torsion Testing Machine is designed for static torsion testing of flexible shafts and other torque-transmitting components. It adopts a horizontal structure with a digital AC servo drive and closed-loop control system, providing smooth and stable torque loading without significant impact.
The machine accurately measures torque and torsion angle and can record test curves and data for evaluating the torsional performance of flexible shafts.
Application
The Flexible Shaft Torsion Testing Machine is mainly used for:
(1) Static torsion testing of flexible shafts
(2) Torsional strength evaluation
(3) Torque-angle characteristic testing
(4) Quality inspection of flexible shaft products
(5) R&D and performance verification of torque-transmitting components
Typical test samples include flexible shafts, control cables with torque-transmitting structures, drive shafts, and other flexible torque-transmitting components.
Standards
(1) GB/T 2611 — General technical requirements for testing machines
(2) Applicable product or industry standards can be selected according to the specific flexible shaft and test requirements.
Note: The applicable testing standard should be confirmed according to the flexible shaft type, structure, material, and customer’s technical requirements.
