ZLYJ gearbox series are transmission devices, which are specially designed for single-screw extruder with high precision, hard gear surface, accompany with thrust. Adopting the technical specifications stipulated in JB/T9050. 1-1999, all ZLYJ gearboxes are designed accordingly.
Main Features:
1.The material of gear is the high strength alloy steel, it is manufactured by carburizing, quenching (and other heat treatment), gringding process at last. The gear is in high precison ( 6 grade ) and high hardness ( reaches HRC54-62). Besides, it features low noise when operating.
2. It contains high bearing ability thrust, which is performed reliable and can withstand larger axial thrust.
3.All the items are treated by forced lubrication and cooling system except very few small specification products.
4. ZLYJ series gearbox is adopted by six-side processing box. Its normal installation is horizontal, but can also be changed to vertical installation according to customer's requirment.
5.Efficiency transmission, low noise, long operaton time.
