SZL vertical Conical Twin Screw Gearbox introduction
SZL series Vertical conical twin-screw extruder 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.
SZL vertical Conical Twin Screw Gearbox feature
1.The gears are made of high strength alloy steel. The material of the box is made of high quality ductile iron.
2.After casting, full stress treatment is carried out with high strength and beautiful appearance.
3.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.
4.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.
Painted with anti-corrosion oil, and covered with plastic film, then packed in wood box including Fumigation. The inspection should be done at the workshop of manufacturer, photos should be send to buyer to confirm.
The gearboxes are widely used in plastic machinery, plastic industry, environmental protection industry, building materials, electric power, steel, mine, metallurgy, coal, petrochemical, port transportation, municipal construction and many other fields.
SZL 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.
Gearbox processing technology
1.DELING gearbox is designed according to the standard of JB/T9050.1-1999.
2. The gear goes through the process of carburizing quenching heat hardening and gear grinding to achieve the precision of grade 6.
3.All of the gears and shafts are finely grinded, this is sure for a really low level of noise dB even in a high-speed rotating.
4.The whole unit is small volume, high carry capacity, stable drive, low noise and efficiency.
