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.

Ensuring Durability and Strength of Plastic Gearboxes

Manufacturers employ several strategies to ensure the durability and strength of plastic gearboxes:

  • Material Selection: Choosing the appropriate plastic material with the right mechanical properties for the specific application, considering factors like load, speed, temperature, and environment.
  • Engineering Design: Designing gear teeth profiles, dimensions, and housing structures that distribute loads evenly and minimize stress concentrations.
  • Reinforcement: Incorporating additives or reinforcements such as glass fibers, carbon fibers, or minerals to enhance the strength and rigidity of the plastic material.
  • Precision Manufacturing: Utilizing advanced manufacturing techniques, such as injection molding or precision machining, to produce accurate and consistent gear components.
  • Tolerances and Clearances: Ensuring proper tolerances and clearances between gear teeth to reduce friction and prevent premature wear.
  • Testing and Quality Control: Conducting rigorous testing, including load testing, wear testing, and environmental testing, to verify the gearbox’s performance and durability.

By combining these approaches, manufacturers can create plastic gearboxes that meet the required durability and strength standards for various applications.

Contribution of Plastic Gearboxes to Reducing Wear and Tear on Machinery

Plastic gearboxes play a crucial role in minimizing wear and tear on machinery by offering the following benefits:

  • Self-Lubrication: Many plastic materials used in gearboxes have inherent self-lubricating properties. This reduces the need for frequent lubrication, prevents dry friction, and minimizes the chances of component wear.
  • Low Friction and Low Wear: Plastic gearboxes often exhibit lower friction coefficients compared to metal gearboxes. This characteristic results in reduced abrasive wear between gear teeth and other moving parts, prolonging the lifespan of the gearbox and the machinery it operates.
  • Resistance to Corrosion: Plastics are inherently resistant to corrosion, rust, and oxidation. Plastic gearboxes are well-suited for applications in humid, wet, or corrosive environments, where metal components might be susceptible to deterioration.
  • Shock Absorption: Plastic’s inherent ability to dampen vibrations and shocks helps absorb impacts and sudden loads, preventing excessive stress on gear teeth and other components. This feature is particularly beneficial in applications with frequent start-stop cycles or varying loads.
  • No Metal-to-Metal Contact: Plastic gearboxes eliminate the need for metal-to-metal contact between gear teeth. This reduces the likelihood of galling and pitting, common issues in metal gearboxes that can lead to accelerated wear.
  • Reduced Noise and Vibrations: The damping properties of plastic contribute to quieter operation and reduced vibrations, which can further reduce the strain on components and extend their lifespan.

By mitigating factors that contribute to wear and tear, plastic gearboxes help maintain machinery in better condition, leading to increased reliability, longer service life, and reduced maintenance requirements.

Cost-Effective Solutions with Plastic Gearboxes

Plastic gearboxes can indeed offer a cost-effective solution for specific engineering needs, offering several advantages:

  • Material Cost: Plastic materials are generally more cost-effective than metals, making them a budget-friendly option for applications where cost is a significant consideration.
  • Reduced Machining Costs: Plastic gearboxes can often be injection molded or fabricated using less complex machining processes, leading to reduced manufacturing costs.
  • Tooling Expenses: The tooling required for plastic gear manufacturing is often less expensive than that for metal gears, contributing to overall cost savings.
  • Weight Reduction: Plastic gearboxes are lighter than metal counterparts, potentially leading to cost savings in transportation, installation, and overall system design.
  • Lubrication and Maintenance: Some plastic materials possess self-lubricating properties, reducing the need for external lubrication and maintenance, thus lowering long-term operational costs.

However, it’s important to note that plastic gearboxes may not be suitable for all applications, especially those requiring high torque, extreme temperatures, or aggressive operating conditions. Careful consideration of the application’s requirements is essential to determine if plastic gearboxes can provide a cost-effective and reliable solution.
