ZLYJ series reducer is a high-precision hard tooth surface with thrust seat designed for the plastic screw extruder. The product design adopts the technical scope specified by JB / T8853-2001, which is characterized by gears and shafts. The parts are made of high-strength alloy steel, the gears are processed by carburizing, quenching, and gear grinding. The gear precision is GB10095-88, level 6, the tooth surface hardness is HRC54-62, and the oversize thrust bearings are arranged at the front end of the hollow output shaft To withstand the working recoil of the screw, the main standard parts such as bearings and oil seals are made of domestic high-quality products, and imported products can also be equipped according to user needs. The whole machine has the characteristics of small size, high carrying capacity, smooth transmission, low noise and high efficiency. The product performance has reached the international advanced level and can replace the same type of imported products.
