Product Information:

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. The instrument provides precise, real-time data, ensuring reliable results for research, development, and quality control in industrial, educational, and laboratory settings.

Application

(1) Testing the torsional fatigue life of torsion springs in automotive, aerospace, and industrial machinery applications.

(2) Evaluating spiral springs used in mechanical assemblies and precision instruments.

(3) Assessing elastic elements and components in vibration and shock absorption systems.

(4) Fatigue testing of friction mechanisms in mechanical devices.

(5) Research and development of spring materials and components.

(6) Quality control and reliability assessment in manufacturing plants.

(7) Educational and laboratory experiments in mechanical engineering and material science.

(8) Testing springs and components for industrial, mining, and technical supervision departments.

Standards

(1) JB/T 9370 – Torsion Testing Machine Standard.

(2) JJG 269 – Torsion Testing Machine Verification Regulations.

(3) ISO standards for torsional fatigue testing of springs and elastic elements.

(4) JIS standards for torsion and spring fatigue evaluation.

(5) ASTM standards for torsion spring life testing.

(6) DIN standards for torsion fatigue measurement of mechanical components.

Features

(1) Real-time display of rotation speed, torsion angle, and test count.

(2) User-settable torsion angle, speed, and preset test count for full operational control.

(3) Dual display of test speed in both t/m and Hz.

Test Procedures

(1) Install the spring or elastic component securely on the test station.

(2) Set the desired torsion angle, rotation speed, and target test count.

(3) Activate the machine; monitor real-time display for torsion angle, speed, and test count.

(4) Machine automatically stops and sounds a buzzer when the preset count is reached.

(5) Adjust torsion direction or repeat tests as necessary for different samples.

(6) Save the test data using the automatic storage function for future reference.

(7) Carefully remove the sample after testing and record the results.

Maintenance Information

(1) Regularly inspect rotary encoders, fixtures, and clamps for wear or damage.

(2) Lubricate moving and rotating components according to manufacturer guidelines.

(3) Ensure the control panel and display are clean and free from dust.

(4) Check electrical connections periodically to prevent operational faults.

(5) Store the instrument in a clean, dry, and stable environment when not in use.

(6) Follow all safety procedures to prevent injury during operation, particularly when testing high-frequency torsion cycles.
