The design is compact, the gears and gear shafts are made of high-strength alloy steel (20CrNi2MoA), after secondary carburizing and quenching, and precision grinding ensures that the high hardness of the meshing tooth surface, the high toughness of the core, and the high precision (greater than 6 GB/ The modified tooth profile of T10095-2001) greatly improves the carrying capacity of the gearbox, which is 30%-50% higher than the ZLYJ series gearbox of the same specification.
