Product Description SZL series gearbox for conical twin-screw extruder is a special driving unit matched with conical twin-screw rod extruder. It consists of two parts, namely, the reduction box and the distribution box. After reducing speed and increasing torque of the motor, it outputs the motive power to the distribution box, then drives the double output shafts (the included angle is the same with that of twin-screw rods) via a pair of small conical spiral gears with driving ration of 1:1,thus to drive screw rods to rotate outward with different direction. Product Feature 1.There are involute cylindrical gearbox, which data and structure are optimally designed by the computer. 2.The gears are made of top-quality high strength low carbon alloy steel after carbon penetrating, quench and teeth grinding. It has high hardness on teeth surface, large bearing ability, small noise, smooth operation and high driving efficiency. 3.The material of the distribution box is nodular graphite casting iron and the gears have high-strength ground teeth, in which snake-shaped cooling water pipes are distributed. 4.The maximum input speed of the gearbox is normally not larger than 1500 rpm. 5.The temperature in work environment is -10-45.When temperature is lower than 0 the lubricant oil should be preheated to + 10 before starting.
JIANGYIN DELING GEARBOX CO.,LTD, a professional designer and producer of hard tooth surface gearboxes, 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 for over 20 years in China. If you are interesting in our products, please contact me email Shirley@dlclx.cn, whatsapp: +8613706160536. SZ horizontal 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. url:http://www.delinggearbox.com
