Twin Screw Gearbox Introduction
Twin Screw Gearbox adopting latest standard ISO1328,the precision of cylindrical gear of spherical involute, and combining our long term experience and specialty of twin-screw extruders, SHTDN gearboxes are meticulously designed with top advanced designing ideas in the world for co-orientated rotating twin-screw extruders, with entirely independent Intellectual Property Rights.
The gears are made of carburizing steel of high-strength alloy of good quality by carburizing and quenching for teeth, of which all the gear grinding processes are finished by imported gear grinding machines. Gear parameters are optimized and specially designed for the characteristics of twin screw extruders, reducing stress concentration on root of gear and improving gear surface conditions. We have improved gear intension of flexural fatigue, fatigue strength and ratio of wide diameter. We have also adopted the latest designing idea and technology of heating treatment for the structure of gears, thereby ensured gears from uniformity of precision and strength.

Can a Worm Gearbox be Used for High-Speed Applications?
Worm gearboxes are generally not recommended for high-speed applications due to their inherent design characteristics. Here’s why:
- Efficiency: Worm gearboxes tend to have lower efficiency compared to other gearbox types, which means they can generate more heat and experience more energy loss at high speeds.
- Heat Generation: The sliding contact between the worm and worm wheel in a worm gearbox can lead to significant friction and heat generation, especially at high speeds. This heat can cause thermal expansion, affecting the gearbox’s performance and longevity.
- Wear and Noise: High speeds can exacerbate wear and noise issues in worm gearboxes. Increased friction and wear can lead to faster degradation of components, resulting in reduced lifespan and increased maintenance needs.
- Backlash: Worm gearboxes may have higher backlash compared to other gearbox types, which can impact precision and accuracy in high-speed applications.
While worm gearboxes are more commonly used in applications requiring high torque and moderate speeds, they may not be the best choice for high-speed scenarios. If high-speed operation is a requirement, other gearbox types such as helical, spur, or planetary gearboxes are often better suited due to their higher efficiency, lower heat generation, and reduced wear at elevated speeds.
How to Calculate the Input and Output Speeds of a Worm Gearbox?
Calculating the input and output speeds of a worm gearbox involves understanding the gear ratio and the principles of gear reduction. Here’s how you can calculate these speeds:
- Input Speed: The input speed (N1) is the speed of the driving gear, which is the worm gear in this case. It is usually provided by the manufacturer or can be measured directly.
- Output Speed: The output speed (N2) is the speed of the driven gear, which is the worm wheel. To calculate the output speed, use the formula:
N2 = N1 / (Z1 * i)
Where:
N2 = Output speed (rpm)
N1 = Input speed (rpm)
Z1 = Number of teeth on the worm gear
i = Gear ratio (ratio of the number of teeth on the worm gear to the number of threads on the worm)
It’s important to note that worm gearboxes are designed for gear reduction, which means that the output speed is lower than the input speed. Additionally, the efficiency of the gearbox, friction, and other factors can affect the actual output speed. Calculating the input and output speeds is crucial for understanding the performance and capabilities of the worm gearbox in a specific application.
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.
