ZLYJ series Gearbox for Single Screw Extruder is a kind of special gearbox researched and developed by importing the most advanced technology of the hard tooth surface in the world. For recent ten years, It is widely used in the top and middle-grade plastic, rubber, and chemical fiber extruders, and sell well in the domestic and overseas, and has a higher reputation in the industry.
Product Feature
1.The whole machine looks beautiful and liberal, which can be used both vertically and horizontally. It can suit multiple requirements of assembling.
2.The gear data and box structure are optimally designed by the computer. The gears are made of top-grade low carbon alloy steel with Grade 6 precision of teeth after carbon penetrating, quench and teeth grinding. The hardness of the teeth surface is 54-62 HRC. The gear pair has stable running, low noise, and has high driving efficiency.
3.The assembling connector has the precision of radial run-out and end face run-out at the international level, and can be easily connected with the screw rod of the machine barrel.
4.The bearing structure of the output shaft has a unique style, which can effectively prolong the service life of the bearings.
5.All standard parts such as bearing, oil seal, lubricant oil pump, etc. are all top quality products selected from domestic famous manufacturers. They can be also selected from imported products as per the requirement of the customer.
SZ 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.
YPS series gearbox is a standard driving part designed and developed for counter-rotating parallel twin screw extruder. Its gear is made of low carbon alloy steel by carbon penetrating, quench and teeth grinding to reach high strength and precision. The output shaft is finely made of special alloy steel to suit the requirement of large output torque. The thrust bearing group is a combination design that adopts advanced tandem thrust cylindrical roller bearing and full complement cylindrical roller bearings which have a large bearing capacity. The lubrication style adopts oil immersion and spray lubrication and it can also be equipped with pipe style cooling system based on the different requirements of the machine. The whole machine has a well-balanced appearance advanced structure superior bearing performance and smooth operation. It is an ideal selection of counter-rotating parallel twin screw extruder gearbox.
The gearbox of a wind turbine is one of the key components in wind power generation equipment, used to transfer the kinetic energy of the rotating wind turbine to the generator, thereby generating electrical energy. It is usually composed of multiple gears, which increase the speed of the wind turbine through precise transmission ratios and convert it into a speed suitable for the operation of the generator. Usually, the speed of the wind turbine is very low and far from the required speed for the generator to generate electricity. It must be achieved through the speed increasing effect of the gearbox gear pair, so the gearbox is also called a speed increasing gearbox.
