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.

Importance of Lubrication in Gearbox Performance

Lubrication plays a critical role in ensuring the optimal performance, longevity, and reliability of gearboxes. Proper lubrication provides several key benefits:

• Reduces Friction and Wear: Lubrication forms a protective layer between gear teeth, bearings, and other moving components, reducing friction and minimizing wear and tear.
• Heat Dissipation: Lubricants help dissipate the heat generated during gear operation, preventing overheating and potential damage to components.
• Noise Reduction: Adequate lubrication can dampen noise and vibration produced by gear meshing, leading to quieter and smoother operation.
• Sealing and Contaminant Prevention: Lubricants create a barrier that seals out contaminants like dust, dirt, and moisture, preventing their entry and reducing the risk of corrosion and damage.
• Enhanced Efficiency: Proper lubrication reduces energy losses due to friction, improving the overall efficiency of the gearbox.
• Extended Lifespan: Lubrication helps prevent premature component wear and failure, extending the lifespan of the gearbox and minimizing the need for costly repairs or replacements.
• Optimal Performance: Gearboxes operate within specified tolerances when properly lubricated, ensuring they deliver the intended performance and functionality.

It's essential to use the recommended lubricant type, viscosity, and change intervals specified by the gearbox manufacturer to ensure the best possible performance and longevity. Regular monitoring and maintenance of lubrication levels are crucial to preserving the health of the gearbox and its components.
