Product Description

Overview

Product Description 

Wide Selection of Gearbox Products
The gearbox usually adopts a general design scheme, but in special cases, the design scheme of the gearbox can be changed according to the demands of the user, and it can be modified into an industry-specific gearbox. In the design scheme of the gearbox, the parallel shaft, vertical shaft, general box, and various parts can be changed

Advantages

• Absorption of very high torques and axial forces
• No need for separate thrust housing & bearing.
• Easy alignment (screw directly fits into the vore of gear box)
• Easy to assemble & dismantle.
• Very heavy duty spherical roller thrust bearing is provided.
• Power saving. (you may save up to 20 % power.)
• Less requirement of space.
• For bigger sizes water cooling is provided 
• No maintenance required except periodic oil level checking.
• Higher productivity 

Features

 

• Twin Screw Extruder Gearboxes offer the dual shaft counter rotating. The range is available for various center distances
• The gearboxes are available with co-rotating and counter rotating variants
• To work under heavy loading force, the high level dissipation and oil lubrication system are provided. The axial roller type swivel thrust with the thrust bearing coupled in tandem way support the axial thrust
• High torque and high speed output rate

 

Processing Characteristics of Screw Shaft:

1.Suitable suggestion on material to ensure components performance and extend lifetime of products.
2.Professional technical team can provide surveying and mapping support.
3.All components are finished by CNC machine.
4.Sophisticated quality management system ensure superior quality.

Applications
X helical gear units for double-screw extruders with parallel drive shafts and the same direction of screw rotation are used mainly in the manufacture of granulates and the refining of raw plastics. Other areas of application include:

• Paint and lacquer industry
• Washing agent industry
• Foodstuff industry (e.g. bread, pasta)
• Animal-feed industry (dog, cat other animal food 

Maintenance of the gearbox of the dual-screw extruder
1. The gear box of the dual-screw extruder should be well-ventilated, and the working environment temperature should be within the range of 5-35 °C.
2. Always check the oil quantity of the gear lubricating oil in the box to ensure that the transmission parts in the box are well lubricated.
3. Pay attention to check the bearing parts of the box frequently. The oil temperature of the oil tank of the transmission box should not exceed 70 ºC during operation.
4. The newly put into use gearbox needs to replace the lubricating oil after 250 hours of operation. The oil change time depends on the state of the oil. It is recommended to replace it after 4000-8000 hours of operation or once a year.
5. The gearbox of the dual-screw extruder needs to be regularly maintained and inspected once a year 


Operating Process
1. The gear on the input shaft is driven by the motor and starts to rotate.
2. The rotating input gear meshes with other gears inside the gearbox, transmitting power.
3. Different-sized gears within the gearbox are combined to form a gear train. Through continuous meshing and rotation, the high-speed, low-torque power from the input shaft gradually converts into low-speed, high-torque output.
4. The output shaft is connected to the last gear and transfers the output torque to the load.
5. Gear reduction gearboxes typically include lubrication and cooling systems to ensure smooth operation and prevent overheating and damage.
6. Our extruder gearbox converts high-speed, low-torque power into low-speed, high-torque output by changing the size ratios and meshing arrangements of different gears, achieving the function of speed reduction.

Types of Gearboxes:
Based on customer requirements, gear reduction gearboxes can be classified according to the size of the output shaft, center distance of the output shaft, output speed, and torque. Alternatively, we can provide several commonly used types of gearboxes for customers to choose from.
