Universal Joint Torque Testing Machine

The Universal Joint Torque Testing Machine is widely used for evaluating the torsional mechanical performance of universal joints, universal joint adapters, and other torque-transmitting tools. It is suitable for hardware tool manufacturers, quality supervision authorities, metrology and testing institutes, metallurgy, aerospace, automotive, and other industries.

Main Functions

Torque Testing: Measures the torque applied to the universal joint during testing.

Peak Torque Measurement: Records the maximum torque reached during the test.

Torsion Angle Measurement: Measures the torsion angle of the specimen.

Curve Analysis: Displays and analyzes:

Torque–Time Curve

Torque–Torsion Angle Curve

Torque–Rotation Angle Curve

Adjustable Fixtures: The fixture spacing can be adjusted to accommodate different specimen sizes.

Computer-Controlled Operation: Provides automated control and real-time test data acquisition.

Data Management: Supports test data storage, retrieval, and test report printing.

Multiple Test Modes: Can be used for torsional performance, peak torque, and destructive testing according to the specified test requirements.

Recommended Test Environment

Ambient Temperature: 10–35°C

Relative Humidity: ≤80%

Installation: Stable foundation or workbench

Environment: Free from significant vibration and corrosive media

Power Supply: Voltage fluctuation within ±10% of the rated voltage

The equipment is suitable for product development, quality control, incoming inspection, finished-product testing, and torsional performance evaluation of universal joints and related fastening tools.
