SZL series gearboxes for vertical conical twin screw extruder
SZL series gearbox is a special mechanical drive device designed to match with conical twin-screw extruder. This product is improved on the basis of SZ series. The integrated design of the distribution box and the transmission box has the advantages of compact structure, convenient installation and debugging.
SZL series 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, tooth surface hardness HRC54-62. 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.
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.
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
DELING gearbox is designed according to the standard of JB/T9050.1-1999. 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. 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. The whole unit is small volume, high carry capacity, stable drive, low noise and efficiency.
