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.

Comparison of Helical Gearboxes and Bevel Gearboxes
Helical gearboxes and bevel gearboxes are both widely used for power transmission in various industrial applications. Here’s a comparison of their performance:
- Gear Meshing: Helical gearboxes use helical gears with inclined teeth that gradually engage, resulting in smoother and quieter operation compared to the more abrupt engagement of straight-cut bevel gears.
- Efficiency: Helical gearboxes generally offer higher efficiency due to their helical gear design, which distributes loads evenly across the teeth. Bevel gearboxes can have slightly lower efficiency due to the sliding action of gear teeth during engagement.
- Load Capacity: Helical gearboxes can handle higher loads and torque due to the larger contact area of the gear teeth. Bevel gearboxes are suitable for moderate loads and applications where the direction of power transmission needs to be changed.
- Space Efficiency: Bevel gearboxes are often more compact and suitable for applications where space is limited and a change in direction is required. Helical gearboxes may require more space due to the parallel shaft arrangement.
- Noise and Vibration: Helical gearboxes generate less noise and vibration compared to straight-cut bevel gearboxes. Bevel gearboxes can be noisier, especially at higher speeds.
- Application: Helical gearboxes are commonly used in applications requiring smooth and efficient power transmission, such as conveyors, pumps, and mixers. Bevel gearboxes are preferred for applications where changes in direction are necessary, such as in automotive differentials and printing presses.
Ultimately, the choice between helical and bevel gearboxes depends on the specific requirements of the application, including load capacity, space constraints, efficiency goals, and the need for directional changes in power transmission.
Impact of Thermal Expansion on Helical Gearbox Performance
Thermal expansion can significantly affect the performance of helical gearboxes due to changes in dimensions and clearances caused by temperature variations. Here’s how it impacts:
1. Misalignment: Temperature changes can lead to differential expansion of gearbox components. This can result in misalignment of gears, shafts, and bearings, leading to increased friction, noise, and reduced efficiency.
2. Lubrication: Thermal expansion can alter the clearances within the gearbox, affecting the distribution and viscosity of the lubricating oil. Inadequate lubrication due to temperature-induced changes can result in increased wear and premature failure.
3. Gear Tooth Engagement: Temperature fluctuations can cause gear teeth to expand or contract, affecting the meshing engagement and load distribution. Inconsistent gear tooth contact can lead to uneven wear and reduced gear life.
4. Bearing Performance: Bearings in helical gearboxes are sensitive to temperature changes. Excessive heat can lead to reduced bearing life, increased friction, and potential seizure, affecting overall gearbox performance.
5. Noise and Vibration: Thermal expansion can lead to changes in gear and component clearances, resulting in altered vibration patterns and increased noise levels. This can impact the comfort of the system and indicate potential issues.
6. Material Fatigue: Repeated cycles of thermal expansion and contraction can lead to material fatigue and stress accumulation, reducing the overall lifespan of gearbox components.
Managing Thermal Effects: Manufacturers design helical gearboxes with considerations for thermal expansion, using materials with low coefficients of thermal expansion and incorporating features like expansion joints or thermal isolators. Proper lubrication, monitoring temperature, and maintaining consistent operating conditions are also crucial in mitigating thermal expansion effects.
Understanding and managing the impact of thermal expansion is essential to maintain the performance, efficiency, and durability of helical gearboxes.
Handling High Torque and Heavy Loads in Helical Gearboxes
Helical gearboxes are well-suited for handling high torque and heavy loads due to their unique design and meshing characteristics:
- Helical Teeth: The helical shape of the gear teeth allows for gradual and continuous contact between the teeth during meshing. This results in smoother load distribution and reduced impact forces, making helical gears capable of handling heavy loads.
- Multiple Tooth Contact: Helical gears have multiple teeth in contact at any given time, spreading the load over a larger area of gear teeth. This helps to distribute the load evenly and prevent localized wear and stress concentrations.
- Increased Tooth Strength: The inclined orientation of helical gear teeth increases the tooth width, leading to greater tooth strength and improved load-carrying capacity.
- Bearings and Shaft Design: The gearbox housing is designed to support heavy loads and provide proper alignment for the shafts and bearings. High-quality bearings and shafts help distribute the load and reduce wear.
- Lubrication: Adequate lubrication is crucial to minimize friction and heat generation between gear teeth. Proper lubrication also helps to dissipate heat generated by the heavy loads.
- Material Selection: High-strength materials with good wear resistance properties are chosen for helical gears to ensure they can withstand the demands of heavy loads.
Overall, the gradual engagement of helical gear teeth and their ability to handle multiple tooth contact positions them as a reliable choice for applications that require high torque and can handle heavy loads. Engineers carefully design helical gearboxes to ensure they can withstand the stresses imposed by the application’s specific requirements.

Helical Gearbox: Overview and Working Mechanism
A helical gearbox is a type of mechanical device used to transmit power and motion between rotating shafts. It employs helical gears, which are cylindrical gears with teeth that are cut at an angle to the gear axis. This design feature gives helical gearboxes their distinctive helical shape and provides several advantages in terms of efficiency, smoothness, and load-bearing capabilities.
The working mechanism of a helical gearbox involves the interaction of helical gears, which mesh together to transmit torque and motion. Here’s how it works:
- Gear Tooth Engagement: When power is applied to the input shaft of the gearbox, the helical gear on the input shaft meshes with the helical gear on the output shaft.
- Helical Angle: The helical angle of the gear teeth causes a gradual engagement between the teeth, resulting in a smooth and quiet meshing process compared to straight-cut gears.
- Torque Transfer: As the input gear rotates, it transfers rotational force (torque) to the output gear through the meshing
Materials Used in Manufacturing Helical Gears
Helical gears are commonly manufactured using a variety of materials to meet specific requirements for strength, durability, wear resistance, and other mechanical properties. Some of the materials commonly used for manufacturing helical gears include:
- Steel: Various types of steel, such as carbon steel, alloy steel, and stainless steel, are frequently used due to their high strength, durability, and wear resistance. They are suitable for a wide range of applications and provide excellent performance.
- Cast Iron: Cast iron gears are known for their cost-effectiveness and good wear resistance. They are often used
Precision and High-Accuracy Applications of Helical Gearboxes
Helical gearboxes are well-suited for precision and high-accuracy applications due to their unique design and performance characteristics:
- Helical Gearing: The helical gears in these gearboxes offer smooth and continuous meshing, resulting in reduced backlash and improved positioning accuracy.
- Efficiency: Helical gearboxes are known for their high efficiency, which minimizes energy losses and heat generation. This is crucial for maintaining precision in applications where even small deviations can have significant impacts.
- Noise and Vibration: The helical gear tooth engagement helps in reducing noise and vibration levels, making them suitable for environments where quiet operation is required.
- Load Distribution: Helical gears distribute load across multiple teeth, minimizing localized wear and extending the lifespan of the gearbox.
- Smooth Motion: Helical gearboxes provide smoother motion transitions, which is crucial in precision applications where jerky or sudden movements are undesirable.
- Positional Accuracy: The reduced backlash and improved meshing characteristics of helical gears contribute to higher positional accuracy, making these gearboxes ideal for applications such as CNC machines, robotics, and medical equipment.
- Compact Design: Helical gearboxes can achieve high gear ratios in a relatively compact form factor, making them suitable for applications where space is limited.
Examples of precision applications where helical gearboxes are commonly used include CNC machining, robotics, semiconductor manufacturing, medical equipment, and metrology devices. The combination of efficiency, smooth operation, and accuracy makes helical gearboxes a preferred choice for achieving consistent and reliable performance in such applications.
in applications where heavy loads and moderate speeds are involved.
- Brass: Brass gears are chosen for applications that require quiet operation and low-speed applications. They offer good corrosion resistance and are commonly used in smaller machinery.
- Bronze: Bronze gears are valued for their excellent wear resistance and compatibility with lubricants. They are often used in heavy-duty applications and situations where high loads are encountered.
- Plastics and Polymers: Certain plastic materials, such as nylon and acetal, are used for gears that require low noise levels and resistance to chemicals and corrosion. They are suitable for applications where lightweight components are essential.
- Aluminum: Aluminum gears are lightweight and corrosion-resistant, making them suitable for applications where weight reduction and corrosion resistance are priorities.
The choice of material depends on factors such as the application’s load, speed, environment, and desired performance characteristics. Manufacturers select materials that best align with the specific requirements of the helical gear system, ensuring optimal function and longevity.
of their helical teeth.
- Direction of Rotation: Depending on the arrangement of the helical gears, the output shaft’s direction of rotation can be the same as or opposite to that of the input shaft.
- Load Distribution: The helical design allows for multiple teeth to be engaged at any given moment, distributing the load more evenly across the gears. This results in higher load-carrying capacity and reduced wear on gear teeth.
- Efficiency: Helical gearboxes are known for their high efficiency due to the gradual tooth engagement and larger contact area, resulting in minimal energy loss as compared to other gear types.
Helical gearboxes find applications in various industries where smooth operation, high efficiency, and compact design are important. They are commonly used in machinery, conveyors, automotive transmissions, industrial equipment, and more.

Differences Between Helical Gearboxes and Spur Gearboxes
Helical gearboxes and spur gearboxes are two common types of gearboxes used in various applications. Here are the key differences between them:
- Tooth Desi
Precision and High-Accuracy Applications of Helical Gearboxes
Helical gearboxes are well-suited for precision and high-accuracy applications due to their unique design and performance characteristics:
- Helical Gearing: The helical gears in these gearboxes offer smooth and continuous meshing, resulting in reduced backlash and improved positioning accuracy.
- Efficiency: Helical gearboxes are known for their high efficiency, which minimizes energy losses and heat generation. This is crucial for maintaining precision in applications where even small deviations can have significant impacts.
- Noise and Vibration: The helical gear tooth engagement helps in reducing noise and vibration levels, making them suitable for environments where quiet operation is required.
- Load Distribution: Helical gears distribute load across multiple teeth, minimizing localized wear and extending the lifespan of the gearbox.
- Smooth Motion: Helical gearboxes provide smoother motion transitions, which is crucial in precision applications where jerky or sudden movements are undesirable.
- Positional Accuracy: The reduced backlash and improved meshing characteristics of helical gears contribute to higher positional accuracy, making these gearboxes ideal for applications such as CNC machines, robotics, and medical equipment.
- Compact Design: Helical gearboxes can achieve high gear ratios in a relatively compact form factor, making them suitable for applications where space is limited.
Examples of precision applications where helical gearboxes are commonly used include CNC machining, robotics, semiconductor manufacturing, medical equipment, and metrology devices. The combination of efficiency, smooth operation, and accuracy makes helical gearboxes a preferred choice for achieving consistent and reliable performance in such applications.
gn:
The main difference between helical and spur gearboxes lies in their tooth design. Helical gearboxes feature helical teeth that are cut at an angle to the gear axis, while spur gearboxes have straight-cut teeth that run parallel to the gear axis. - Engagement: Helical gearboxes offer a gradual and smooth engagement of teeth due to their helical tooth design. This results in reduced noise and vibration compared to spur gearboxes, which can have more abrupt and noisy tooth engagement.
- Load Distribution: Helical gearboxes have a higher contact ratio between teeth at any given time, which leads to better load distribution across the gear teeth. Spur gearboxes, on the other hand, have fewer teeth in contact at a time, potentially leading to higher stress on individual teeth.
- Efficiency: Helical gearboxes tend to be more efficient than spur gearboxes due to the helical tooth design, which reduces friction and energy losses during gear meshing. The gradual engagement of helical teeth contributes to this higher efficiency.
- Noise and Vibration: Helical gearboxes generate less noise and vibration compared to spur gearboxes. The helical tooth design and smooth engagement help in reducing the impact of gear meshing on overall noise levels.
- Applications: Helical gearboxes are commonly used in applications that require higher torque and smoother operation, such as heavy machinery, automotive transmissions, and industrial equipment. Spur gearboxes are suitable for applications with moderate loads and where noise considerations are not critical.
Overall, helical gearboxes offer advantages in terms of efficiency, load distribution, and noise reduction compared to spur gearboxes. However, the choice between the two depends on specific application requirements and factors such as torque, speed, space constraints, and noise considerations.
