Clutch Torsional Fatigue Testing Bench
Category：Torsion Testing Machine
Introduction
The Clutch Torsional Fatigue Testing Bench is mainly designed for the torsional durability, torsional fatigue, torsional torque, torsion cycles, and torsion frequency performance testing of mechanical clutches and electromagnetic clutch driven disc assemblies.
The system consists of a loading system, transmission system, digital data acquisition and processing system, and computer measurement, control, and display system.
It is suitable for torsional mechanical performance testing of various clutches and related components.
The machine adopts computer control and screen display, equipped with a digital data acquisition and control system and a full digital AC servo system.
It adopts a planetary reducer transmission system, featuring uniform loading, stable operation, no impact during testing, and accurate data acquisition and control.
Applicable Standards
GB/T 2611 — General Requirements for Testing Machines
GB/T 10128 — Metallic Materials — Torsion Test Method at Room Temperature
JJG 269 — Verification Regulation of Torsion Testing Machines
Features
It can be used for torsional durability testing of various types and specifications of mechanical and electromagnetic clutches.
Single-direction torsion: 0 to a specified angle (torque).
Bidirectional torsion: -specified angle (torque) → 0 → +specified angle (torque).
Torsion angle loading with torque monitoring, and generation of corresponding curves.
Torque loading with angle monitoring, and generation of corresponding curves.
