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.

Materials Used in Manufacturing Cycloidal Gearboxes

Cycloidal gearboxes are constructed using a variety of materials to ensure durability, strength, and efficient operation. Some common materials used include:

  • Steel: Steel is a popular choice due to its high strength and durability. It can withstand heavy loads and provides excellent wear resistance, making it suitable for industrial applications.
  • Aluminum: Aluminum is chosen for its lightweight properties and corrosion resistance. It’s often used in applications where weight is a concern, such as aerospace and robotics.
  • Cast Iron: Cast iron offers good heat dissipation and is known for its high resistance to wear and shock. It’s commonly used in heavy-duty applications that require high torque and strength.
  • Alloys: Various alloy combinations can be used to enhance specific properties such as corrosion resistance, heat resistance, and strength.
  • Plastics and Composites: In some cases, plastic or composite materials may be used, particularly in applications where low noise, lightweight construction, and corrosion resistance are essential.

The material selection depends on factors like the application’s torque, speed, environmental conditions, and desired performance characteristics. Each material offers a unique set of advantages, allowing cycloidal gearboxes to be customized to meet diverse industrial needs.

History of Cycloidal Gear System Development

The history of cycloidal gear systems dates back to ancient times, with various forms of non-circular gears being used for specialized applications. The concept of the cycloidal gear system as we know it today, however, has evolved over centuries of engineering and innovation:

  • Ancient Roots: The concept of using non-circular gears can be traced back to ancient civilizations, where devices like the “Antikythera Mechanism” (c. 150-100 BC) employed non-circular gear arrangements.
  • Cam Mechanisms: During the Renaissance, engineers and inventors like Leonardo da Vinci explored mechanisms involving cams and followers, which are precursors to modern cycloidal gears.
  • Cycloidal Motion Studies: In the 19th century, engineers and mathematicians like Franz Reuleaux and Robert Willis studied and developed mechanisms based on the principles of cycloidal motion.
  • Early Cycloidal Gearboxes: The development of cycloidal gear systems gained momentum in the late 19th and early 20th centuries, with inventors like Emile Alluard and Louis André creating early forms of cycloidal gear mechanisms and gearboxes.
  • Cycloidal Drive: The term “cycloidal drive” was coined by James Watt in the 18th century, referring to mechanisms that produce a motion resembling a rolling circle.
  • Modern Cycloidal Gearboxes: The development of modern cycloidal gearboxes was further advanced by engineers like Ralph B. Heath, who patented the “Harmonic Drive” in the 1950s. This invention marked a significant step in the advancement and commercialization of precision cycloidal gear systems.
  • Advancements and Applications: Over the decades, cycloidal gear systems have found applications in robotics, aerospace, automation, and other fields that require compactness, precision, and high torque capabilities.

The history of cycloidal gear system development reflects the contributions of many engineers and inventors who have refined and advanced the technology over time. Today, cycloidal gearboxes continue to play a crucial role in various industries and applications.

Advantages of Using a Cycloidal Gearbox

Cycloidal gearboxes offer several advantages that make them well-suited for various applications:

  • High Torque Density: Cycloidal gearboxes provide a high torque output relative to their size and weight. This makes them ideal for applications where space is limited, and high torque is required.
  • Compact Design: The unique arrangement of cycloidal pins and lobed profiles results in a compact gearbox design. This is advantageous when dealing with constrained installation spaces.
  • Smooth and Precise Motion: Cycloidal motion generates smooth and controlled movement, making these gearboxes suitable for applications requiring accurate positioning, such as robotics and automation.
  • High Shock Load Capacity: The multiple points of contact between the cycloidal pins and the lobes distribute the load, allowing cycloidal gearboxes to handle sudden shocks and overloads effectively.
  • Backlash Elimination: Cycloidal gearboxes exhibit minimal backlash due to the nature of their motion. This is beneficial in applications where precise motion reversal is crucial.
  • High Efficiency: The rolling contact between the pins and lobes contributes to efficient power transmission, resulting in relatively high efficiency levels.
  • Reduced Wear and Noise: The rolling motion in cycloidal gearboxes leads to reduced wear on components, resulting in lower maintenance requirements and quieter operation.
  • Versatility: Cycloidal gearboxes can handle a wide range of ratios and speeds, making them suitable for various industrial and automation applications.

Due to these advantages, cycloidal gearboxes are commonly used in robotics, automation, packaging machinery, conveyors, and other applications where compactness, high torque, and precise motion are critical.
