AI Technical Summary
Existing traditional propeller clamp structures rely on the motor output shaft to drive the propeller clamp to rotate, which results in the output bearing being subjected to large torque and stress, making it prone to problems such as unstable rotation, vibration, poor installation accuracy, insufficient rigidity, and easy fatigue damage.
The structure employs an eccentric block and anti-detachment plate to disperse the force at the motor output end, and uses rolling bearings instead of sliding contact. Combined with reinforcing ribs and soft rubber design, it improves the stability and durability of the structure.
It effectively reduces the overall stress of propeller clamp rotation, improves rotational stability and installation accuracy, reduces the coefficient of friction, enhances structural rigidity and durability, and improves power transmission efficiency and aerodynamic performance.
