SJZ vertical conical twin screw gearbox introduction
SJZ vertical conical twin screw gearbox is a special mechanical drive device designed to match with conical twin-screw extruder. The device decelerates the speed and increases the torque of the power from master motor through gearbox before exporting it to the long shaft of distribution box that drives short shaft through a pair of slender cone screw gear with drive ratio of 1:1. Long shaft and short shaft drive short screw at the same angel as screw to extrude high-quality products in the way of different direction and outward turning.
SJZ vertical conical twin screw gearbox features
The gears are made of high strength alloy steel. The gear goes through the process of carburizing quenching heat hardening and gear grinding to achieve the precision of grade 6, The whole unit is small volume, high carry capacity, stable drive, low noise and high efficiency. The material of the box is made of high quality ductile iron. After casting, full stress treatment is carried out with high strength and beautiful appearance.
Features of gear units
1.Adopt high grade alloy with case-hardened technology for gears and pinions. Hardness of teeth surface reaches as high as 54-62 HRC, grinding precision reaches grand 6.
2.Compact structure, reliable operation, stable transmission, strong load capacity, large range of output torque, extensive power coverage.
3.Excellent heat dissipation, impact resistance, low noise, long service life.
4.The main standard parts, like bearing and oil seal, adopt domestic high-quality brand products, and also can use imported products according to customer's request.
5.With oil immersion lubrication and forced lubrication. Configurable external cooler, with automatic protection system for oil temperature, oil pressure and flow rate, to ensure the reliable work of gear units.
Deling group was established in 2002,To become the most competitive enterprises of gear transmission industry, we make our products and service value superior and recognized by customers. Through our excellent staff and procedure to keep sustained competitiveness.
