SDN series Triple Reduction Helical Gear Unit with Feet
Characteristic:
- Using unit structure design, priority number system for specifications, main parameters, and transmission ratio, high standardization and generalization of spare parts and components, good interchangeability, easy to organize production and rapid delivery.
- The gear parameters are all new scientific research results optimized by the computer, so that the reducer has the characteristics of large transmission power per unit volume and light weight.
- The gear is made of high-quality alloy steel, after carburizing and quenching treatment, the gear hardness can reach 60HRC, with high allowable stress and good wear resistance, so it has large load-bearing capacity and long life.
- The gear accuracy is DIN standard 6 grades, gear grinding, and some specifications adopt tooth profile and tooth profile modification, stable transmission and low noise.
- The transmission ratio range is large with i=7.1~500.
