  • 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.

Calculating Gear Ratio in a Worm Reducer

The gear ratio in a worm reducer is determined by the number of teeth on the worm wheel (also known as the worm gear) and the number of threads on the worm shaft. The gear ratio formula for a worm reducer is:

Gear Ratio = Number of Teeth on Worm Wheel / Number of Threads on Worm Shaft

For example, if the worm wheel has 60 teeth and the worm shaft has a single thread, the gear ratio would be 60:1.

It’s important to note that worm reducers have an inherent self-locking property due to the angle of the worm threads. As a result, the gear ratio also affects the mechanical advantage and the system’s ability to resist backdriving.

When calculating the gear ratio, ensure that the worm reducer is properly designed and that the gear ratio aligns with the desired mechanical characteristics for your application. Additionally, consider factors such as efficiency, load capacity, and speed limitations when selecting a gear ratio for a worm reducer.

Energy Efficiency of a Worm Gearbox: What to Expect

The energy efficiency of a worm gearbox is an important factor to consider when evaluating its performance. Here’s what you can expect in terms of energy efficiency:

  • Typical Efficiency Range: Worm gearboxes are known for their compact size and high gear reduction capabilities, but they can exhibit lower energy efficiency compared to other types of gearboxes. The efficiency of a worm gearbox typically falls in the range of 50% to 90%, depending on various factors such as design, manufacturing quality, lubrication, and load conditions.
  • Inherent Losses: Worm gearboxes inherently involve sliding contact between the worm and worm wheel. This sliding contact generates friction, leading to energy losses in the form of heat. The sliding action also contributes to lower efficiency when compared to gearboxes with rolling contact.
  • Helical-Worm Design: Some manufacturers offer helical-worm gearbox designs that combine elements of helical and worm gearing. These designs aim to improve efficiency by incorporating helical gears in the reduction stage, which can lead to higher efficiency compared to traditional worm gearboxes.
  • Lubrication: Proper lubrication plays a significant role in minimizing friction and improving energy efficiency. Using high-quality lubricants and ensuring the gearbox is adequately lubricated can help reduce losses due to friction.
  • Application Considerations: While worm gearboxes might have lower energy efficiency compared to other types of gearboxes, they still offer advantages in terms of compactness, high torque transmission, and simplicity. Therefore, the decision to use a worm gearbox should consider the specific requirements of the application, including the trade-off between energy efficiency and other performance factors.

When selecting a worm gearbox, it’s essential to consider the trade-offs between energy efficiency, torque transmission, gearbox size, and the specific needs of the application. Regular maintenance, proper lubrication, and selecting a well-designed gearbox can contribute to achieving the best possible energy efficiency within the limitations of worm gearbox technology.

Advantages of Using a Worm Reducer in Mechanical Systems

Worm reducers offer several advantages that make them suitable for various mechanical systems:

  • High Gear Reduction Ratio: Worm gearboxes provide significant speed reduction, making them ideal for applications that require a high gear reduction ratio without the need for multiple gears.
  • Compact Design: Worm reducers have a compact and space-saving design, allowing them to be used in applications with limited space.
  • Self-Locking: Worm gearboxes exhibit self-locking properties, which means that the worm screw can prevent the worm wheel from reversing its motion. This is beneficial for applications where the gearbox needs to hold a load in place without external braking mechanisms.
  • Smooth and Quiet Operation: Worm gearboxes operate with a sliding motion between the teeth, resulting in smoother and quieter operation compared to some other types of gearboxes.
  • High Torque Transmission: Worm gearboxes can transmit high torque levels, making them suitable for applications that require powerful torque output.
  • Heat Dissipation: The sliding action between the worm screw and the worm wheel contributes to heat dissipation, which can be advantageous in applications that generate heat during operation.
  • Stable Performance: Worm reducers offer stable and reliable performance, making them suitable for continuous operation in various industrial and mechanical systems.

Despite these advantages, it’s important to note that worm gearboxes also have limitations, such as lower efficiency compared to other gear types due to the sliding motion and potential for higher heat generation. Therefore, selecting the appropriate type of gearbox depends on the specific requirements and constraints of the application.

How to Calculate the Efficiency of a Worm Gearbox

Calculating the efficiency of a worm gearbox involves determining the ratio of output power to input power. Efficiency is a measure of how well the gearbox converts input power into useful output power without losses. Here’s how to calculate it:

  • Step 1: Measure Input Power: Measure the input power (Pin) using a power meter or other suitable measuring equipment.
  • Step 2: Measure Output Power: Measure the output power (Pout) that the gearbox is delivering to the load.
  • Step 3: Calculate Efficiency: Calculate the efficiency (η) using the formula: Efficiency (η) = (Output Power / Input Power) * 100%

For example, if the input power is 1000 watts and the output power is 850 watts, the efficiency would be (850 / 1000) * 100% = 85%.

It’s important to note that efficiencies can vary based on factors such as gear design, lubrication, wear, and load conditions. The calculated efficiency provides insight into how effectively the gearbox is converting power, but it’s always a good practice to refer to manufacturer specifications for gearbox efficiency ratings.

Lubrication Requirements for a Worm Gearbox

Lubrication is crucial for maintaining the performance and longevity of a worm gearbox. Here are the key considerations for lubricating a worm gearbox:

  • Type of Lubricant: Use a high-quality, high-viscosity lubricant specifically designed for worm gearboxes. Worm gearboxes require lubricants with additives that provide proper lubrication and prevent wear.
  • Lubrication Interval: Follow the manufacturer’s recommendations for lubrication intervals. Regularly check the gearbox’s temperature and oil condition to determine the optimal frequency of lubrication.
  • Oil Level: Maintain the proper oil level to ensure effective lubrication. Too little oil can lead to insufficient lubrication, while too much oil can cause overheating and foaming.
  • Lubrication Points: Identify all the lubrication points on the gearbox, including the worm and wheel gear surfaces. Apply the lubricant evenly to ensure complete coverage.
  • Temperature: Consider the operating temperature of the gearbox. Some lubricants have temperature limits, and extreme temperatures can affect lubricant viscosity and performance.
  • Cleanliness: Keep the gearbox and the surrounding area clean to prevent contaminants from entering the lubricant. Use proper filtration and seals to maintain a clean environment.
  • Monitoring: Regularly monitor the gearbox’s temperature, noise level, and vibration to detect any signs of inadequate lubrication or other issues.

Proper lubrication will reduce friction, wear, and heat generation, ensuring smooth and efficient operation of the worm gearbox. Always refer to the manufacturer’s guidelines for lubrication specifications and intervals.
