Product Description

Product Specification 

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 speciations stipulated in JB/T9050.1-1999, all ZLYJ gearbox are designed accordingly.

Main features:
1. The material of gear is the high strength alloy steel. It is manufactured by carburizing ang quenching (and other heat treatment ), grinding processing at last. The gear is in high precision(6 grade)and high hardness(reach HRC54-62). Besides, it features low noise when operation.
2. It contains high bearing ability thrust which is performed reliable and can withstand larger axial thrust.
3. All the item are treatment by force lubrication and cooling system except very small speciations products.
4. ZLYJ series gearbox is adopted by six-side processing box. Its normal installation is horizontal, but also can be changer to vertical installation according to customer requirement.
5. Efficiency transmission, low noise long operation time.
6. The gearbox housing are ductile cast iron case, gear materials be make use of highly alloy steel
