Vertical Conical Twin Screw Extruder Gearbox Introduction
SZL series Vertical conical twin-screw extruder 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.
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 Extruder 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, 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. 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 Vertical Conical Twin Screw Extruder Gearbox
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.
Gearboxes can equipped with PVC/WPC foam board production line, PVC/WPC flooring production line, PVC imitation Marble sheet/profile production line, PVC wall panel production line, WPC production line.
The experience of countries all over the world shows that the more developed the economy, the greater the consumption of plastic products. Plastic extrusion industry can not do without gearbox, as an important part of power supply.
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.
Deling group was established in 2002. From its very first day of operation to now, it has been concentrating in developing and manufacturing the gearboxes especially for rubber and plastic machinery. Deling is a professional producer of gearboxes and well qualified for ISO 9001. By means of purchasing precised fabricating equipments consistently and continuously investigating and innovating, all of the gearboxes made by Deling are qualified with the features as high torque, low noise dB, less trouble and longer lifetime, which was appreciated by the machinery makers. Deling will take the advantage of the experience accumulated from nearly twenty years and hundreds of thousands of gearboxes being made and to be always look at the demands of the customers to creat the most innovative models. Deling group would delicate ourselves to the rubber and plastic machinery field of world and creat a new brand future with you.
