Functional features
● The external gear is made of high-quality 20CrMnTi/20CrMo/SCM415 material, which is controllable carburizing and quenching. The tooth surface hardness is as high as HRC60土 2, and the tooth surface is precision rolled with a grinding accuracy of JS grade 2: The tooth profile and direction are modified, which has the characteristics of smooth operation, low noise, high load-bearing torque, and low backlash.
● The inner teeth are made by adding T to the commonly used multiple broaching or spiral cutting methods in Taiwan and Japan.
● The input end which connect to the motor using a double opening, double screw cylinder clamp locking mechanism to ensure dynamic balance, concentricity of the joint surface, and power transmission with zero backlash power transmission at high input speeds.
● The modular design of the gearbox input shaft is suitable for any manufacturer and model of motors; The transition flange behind the reducer is made of magnesium aluminum alloy material, which has undergone surface treatment,has beautiful appearance, light weight, and good heat dissipation.
● All reducer models have added skeleton oil seals to prevent oil leakage during high-speed operation. Standard components such as bearings and oil seals choose international and domestic famous brand products;The shaft is made of alloy steel material and undergoes quenching and tempering process to meet the strength and toughness requirements during use.
