The RV reducer is a crucial mechanical device used in the aerospace industry for deceleration and transmission. It plays a vital role in the propulsion, landing, and attitude control systems of rockets. By converting kinetic energy into mechanical energy, it ensures stable thrust during launch, safe landing during return, and precise attitude control during missions. In the successful launch of Shenzhou-17, the RV reducer proved its significance in ensuring the safety and stability of the rocket. Its application value in the aerospace field cannot be underestimated....
