Description

Technical Field

[0002] The magneto in a piston aircraft converts mechanical energy into electrical energy through electromagnetic induction between a high-speed rotating rotor and stator. Regular maintenance or overhaul of the magneto is necessary to ensure proper operation and extend its service life.

[0003] Splines connect and transmit power in magnetos. Worn or damaged splines can reduce power transmission efficiency and even affect the magneto's proper operation. Therefore, splines must be removed for inspection, repair, or replacement to ensure proper operation. Furthermore, during magneto operation, vibrations can affect the axial clearance between the rotor and stator, requiring regular measurement to prevent direct collision or friction between the rotor and stator.

[0004] The existing clamping device for clamping and fixing the auxiliary magnetic motor can only clamp and fix it in any one of the above situations, and has a complex structure. Therefore, it is urgent to research and develop a clamping device with a simple structure that can be adapted to the clamping use in the above two situations. Summary of the Invention
