ZLYJ series extruder special hard tooth surface reducer is a high-precision hard tooth surface gear transmission device with thrust package designed for plastic and rubber screw extruders. It can also be used as an output shaft to withstand axial thrust according to user needs. The transmission parts of other mainframes belong to the hardened gear reducer. The product design refers to various technical specifications stipulated in JB/T9050.1-1999 "Cylinder Gear Reducer". Its characteristic is that the gears and shaft parts are made of high-strength alloy steel after carburizing, quenching and grinding. It is equipped with a thrust seat with high load-bearing capacity. All bearings are designed and configured for more than 3 years of continuous operation. Except for individual products with small specifications, all are equipped with forced lubrication and cooling systems. Withstand the axial thrust of the screw when it is working. The main standard parts such as bearings and oil seals are all domestic high-quality products, and different optional accessories can be equipped according to user needs. The whole machine has the characteristics of small size, high carrying capacity, stable transmission, low noise and high efficiency.
