Spring Torsion Fatigue Testing Machine
The Spring Torsion Fatigue Testing Machine (horizontal type) is an advanced automatic torsional fatigue testing instrument with digital display and counting functionality. It is specifically designed to evaluate the torsional fatigue life of torsion springs, spiral springs, elastic elements, and friction mechanisms.
Standard
JB/T 9370 (Chinese national standard for torsion testing machines)
JJG 269 (Chinese verification regulation for torsion testers)
ISO 12106 (International standard for metallic materials—torsional fatigue testing)
ASTM E143 (Standard test method for torsional fatigue of metallic materials)
Advantages
Automated Precision
Digital control: Real-time display of torque, angle, and cycle count.
Absolute rotary encoder: Eliminates cumulative error for ±0.1° accuracy.
User-Defined Flexibility
Adjustable parameters: Torsion angle (0–300°), frequency (0–5Hz), and direction (clockwise/counterclockwise).
Preset cycles: Auto-stop at 999,999,999 cycles with buzzer alert.
Quiet Operation
50dB noise level: Suitable for lab environments.
Vibration damping: Reduces mechanical resonance during high-cycle testing.
Data Integrity
Automatic storage: Resumes tests after power interruptions.
Multi-unit display: Torque (Nm/lb-ft) and frequency (Hz/RPM) shown simultaneously.
Industrial Durability
Alloy steel frame: Rigid construction with 10-year lifespan.
Sealed bearings: Maintenance-free operation for 20,000+ hours.
