extruder gearbox of ZLYJ series for plastic extruder

Series ZLYJ decelerator is a drive with high-precision and hard tooth surface and thrust bearing designed to match with screw extruder. It is designed according to the specification in code ZBJ19009-88, featured with high-strength alloy steels for gear wheel and shaft parts. The gear is treated with carburation, quenching and gear grinding. Gear wheel precision is GB10095-88, class 6. Tooth surface hardness is HRC54-62. A thrust bearing with over-specificaiton is mounted on the front end of the hollow output shaft to carry back backblow of screw. Domesic quality products are selected for the standard parts such as bearing and oil seal that may also use inported products as required by customer. The whole unit is compact, has high carry capacity, provide stable drive with low noise and high efficiency. The performance of this products is up to the advanced level and a good substitute for imported products of the same kind.
