SJZ Series Conical Double Screw Gearbox Description
SJZ Series Conical Double 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 Series Conical Double Screw Gearbox feature:
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. All oil seals are imported, and the high speed shaft is treated with oil seal and mechanical seal, and the oil leakage rate is low. Using external forced lubrication and brazing plate heat exchanger, the cooling and lubricating system is reliable, the operating temperature is low, and the daily maintenance is convenient.
Specifications of SJZ Series Conical Double Screw Gearbox
SJZ Conical twin screw gearbox can be used in PVC double pipe production lines for producing PVC conduil pipe, diameter from 16mm to 40mm, 16mm to 63mm. it consists of SJZ series extruder, double pipe mold, double pipe vacuum tank, double pipe drawing and cutting machine, stacker. It can produce two pipe at one time to achieve higher production efficiency.
