AI Technical Summary
Technical Problem
The existing harmonic reducer uses bolts to connect the rigid wheel and flange, resulting in poor overall rigidity, a large amount of assembly work, high cost, and the risk of loosening.
Method used
It adopts an integrated rigid wheel structure, with the external flange and rigid wheel integrally formed, and reinforcing ribs are set at the connection to reduce screw connections, improve overall rigidity and assembly accuracy. At the same time, the hollow shaft is designed with internal cooling channels to improve heat dissipation efficiency.
Benefits of technology
It improves the overall rigidity and torsional resistance of the reducer, reduces assembly errors and production costs, enhances power transmission efficiency and stability, and extends service life.
