AI Technical Summary
Existing static torsion testing equipment, when assessing the static strength of the casing and gear shaft, causes additional shear force on the gear shaft of the accessory transmission system due to the gravity of the weights, affecting the accuracy of the test results, limiting the torque loading range, and making it difficult to meet the anti-torque requirements of aero-engines.
The first and second tension ropes work together to apply a preset tension through the loading disk, which counteracts the deformation of the loading disk. Combined with the meshing of helical bevel gears and flat bevel gears, the anti-torsion function is achieved, and the axial force is adjusted to meet the actual use conditions.
This ensures the accuracy of the static torsion test results, expands the torque loading range, and reduces friction, thus meeting the anti-torsion requirements of aero-engines.
