Pulley Torsion Testing Machine
The Pulley Torsion Testing Machine is mainly used for torsional mechanical performance testing of various pulleys, such as vibration damper pulleys. The tested pulley is installed between fixtures with adjustable spacing, allowing the machine to accommodate torsion testing of pulleys with different specifications.
The machine features a Chinese-language display interface for easier operation and system parameter setting. It uses an AC servo motor and precision reducer for transmission, providing uniform and stable loading without impact, as well as accurate data acquisition and control. The machine can generate a detailed A4 paper test report with test curves.
Application
The Pulley Torsion Testing Machine is mainly used for torsional mechanical performance testing of:
(1) Vibration damper pulleys
(2) Crankshaft pulleys
(3) One-way pulleys
(4) Washing machine pulleys
(5) Other pulley components
