China S Series Hard-Toothed Surface Gearbox Speed Reducer - Reliable Suppliers and Factory Solutions
Product Structure
The S series reducer adopts a reinforced high rigidity cast iron box and hard tooth surface gears. The gear material is high-quality alloy steel and has undergone carburizing and quenching treatment. The tooth surface hardness reaches 60 ± 2HRC, and the grinding accuracy is 5-6 levels. The transmission efficiency is as high as 96%, the transmission ratio is finely graded and has a wide range, supporting various installation forms such as foot, B5 flange or B4 flange. Enhance the load-bearing capacity through computer shaping technology and adopt a multi sealing structure to prevent oil leakage. Its modular design supports large-scale production, with models divided according to decreasing torque, allowing for flexible combination of models to form larger transmission ratios. The product design includes noise reduction measures, resulting in low operating noise.
