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.
Safety Measures for Operating Cycloidal Gear Systems
Operating cycloidal gear systems requires careful attention to safety to prevent accidents and ensure the well-being of operators and personnel. Here are important safety measures to consider:
- Training: Provide proper training to operators and maintenance personnel on the operation, maintenance, and potential hazards associated with cycloidal gear systems.
- Protective Equipment: Operators should wear appropriate personal protective equipment (PPE) such as gloves, safety glasses, and protective clothing.
- Lockout-Tagout: Implement lockout-tagout procedures to ensure that the system is de-energized and isolated before any maintenance or repair work begins.
- Regular Inspections: Conduct routine inspections of the gear system to identify any signs of wear, damage, or abnormalities that could compromise safety or performance.
- Lubrication: Follow the manufacturer’s recommendations for lubrication to maintain optimal performance and prevent overheating.
- Temperature Monitoring: Install temperature sensors or monitoring devices to detect any excessive heat buildup in the gearbox, which could indicate a potential issue.
- Proper Ventilation: Ensure that the area where the gear system operates is well-ventilated to prevent the accumulation of heat or harmful fumes.
- Emergency Stop: Install emergency stop buttons or switches that can immediately shut down the system in case of an emergency.
- Clearance Zones: Establish clear clearance zones around the gear system to prevent accidental contact with moving parts.
- Regular Maintenance: Follow a scheduled maintenance routine to keep the gear system in optimal working condition and address any potential safety concerns.
- Operator Awareness: Ensure that operators are aware of the gear system’s potential hazards and safe operating practices.
- Warning Signage: Clearly mark areas where the gear system operates with appropriate warning signs and labels.
- Emergency Procedures: Develop and communicate clear emergency procedures to respond to accidents, malfunctions, or other unexpected events.
Prioritizing safety in the operation and maintenance of cycloidal gear systems is essential to prevent injuries and maintain a safe working environment.
How Does a Cycloidal Gearbox Work?
A cycloidal gearbox operates on the principle of cycloidal motion to transmit rotational power. It consists of a set of components that work together to achieve smooth and efficient motion transmission:
- High-Speed Input Shaft: The gearbox is connected to a high-speed input shaft, typically driven by an electric motor or another power source.
- Cycloidal Pins or Rollers: Surrounding the input shaft are a series of cycloidal pins or rollers arranged in a circular pattern. These pins interact with the lobed profiles of the outer stationary ring.
- Outer Stationary Ring: The outer ring remains stationary and contains lobed profiles. The lobes are designed in a way that allows them to engage with the cycloidal pins as they rotate.
- Motion Transmission: As the input shaft rotates, it causes the cycloidal pins to move along the circular path. The interaction between the cycloidal pins and the lobed profiles of the outer ring results in a unique motion known as epicycloidal or hypocycloidal motion.
This motion generates torque that is transferred from the input shaft to the output shaft of the gearbox. The main advantage of a cycloidal gearbox is its ability to provide high torque output in a compact design. The multiple points of contact between the pins and the lobes distribute the load, enhancing the gearbox’s load-carrying capacity.
Cycloidal gearboxes are known for their smooth and controlled motion, making them suitable for applications requiring precise positioning and high torque capabilities, such as robotics, automation, and industrial machinery.
