One-Way Clutch Torsion Testing Machine
Category：Torsion Testing Machine
Introduction
The One-Way Clutch Torsion Testing Machine is suitable for torsion testing of various one-way clutches, including automotive one-way clutches, starter one-way clutches, and motorcycle one-way clutches.
The test specimen is installed between fixtures with adjustable spacing, allowing the machine to accommodate torsional mechanical performance testing of different specimens. The machine uses computer-controlled operation and can collect torque, peak torque, angle, curve, and other test data. Test data can be stored, retrieved, and printed as test reports.
Application
The One-Way Clutch Torsion Testing Machine is mainly used for:
(1) Automotive one-way clutch torsion testing
(2) Starter one-way clutch torsion testing
(3) Motorcycle one-way clutch torsion testing
(4) One-way clutch torque and peak torque testing
(5) One-way clutch torsion angle testing
(6) Torsional mechanical performance evaluation
