AI Technical Summary
Technical Problem
Existing scissor gears generate internal excitation fluctuations, noise, and vibration under engine torque fluctuations. Wear of the C-shaped springs leads to mechanical failures, and the axial runout of the secondary gear is unstable.
Method used
The spoke structure is adopted, and the damping spokes form a preload between the main gear and the auxiliary gear, eliminating backlash and reducing internal excitation fluctuations caused by torque fluctuations. The uniform preload also eliminates wear and axial runout problems.
Benefits of technology
It improves engine noise, vibration and acoustic roughness, avoids mechanical failures, reduces maintenance costs, ensures controllable load on the secondary gear, and improves the overall performance of the engine.

Abstract
The utility model discloses a spoke formula scissor gear, including main gear, auxiliary gear and spoke damping part, and spoke damping part has the damping spoke of the pre -tightening force that can form in the circumferential direction, and the relative rotation cooperation of overcoming the pre -tightening force is formed through the damping spoke between main gear and auxiliary gear in the circumferential direction, the utility model reduces even eliminates the volatility of scissor gear internal excitation due to the torque fluctuation of engine, thereby improves the noise, vibration and sound roughness problem of engine, eliminates the mechanical failure due to wear, reduces maintenance cost, the utility model pre -tightening force action point is in the same plane has the possibility, thereby eliminates the auxiliary gear axial runout problem due to the action point of C-shaped spring and main gear and auxiliary gear not in the same plane, and the torque attenuation problem does not exist in the reverse drive auxiliary gear, and the load of auxiliary tooth is in the controllable range, guarantees the comprehensive performance of engine.
