Gear Torque Testing Machine
Category：Torsion Testing Machine
Introduction
The Gear Torque Testing Machine is designed to evaluate the torque, torsional strength, and torsional performance of gears and related transmission components. The machine applies controlled rotational torque to the specimen while measuring torque and torsion angle, providing test data for product development, performance evaluation, and quality inspection.
Application
The machine is suitable for testing:
(1) Spur gears
(2) Helical gears
(3) Transmission gears
(4) Automotive gears
(5) Gearbox components
(6) Mechanical transmission components
