Compounding double screw single screw Reducer Extruder gearbox
SHTDN Twin Screw Extruder 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 extruder, SHTDN gearboxes are meticulously designed with top advanced designing ideas in the world for co-orientated rotating twin screw extruder, 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 extruder, 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.
Features:
—-Double drive design enables the B axis to be driven by 2 gears without increasing the tooth width.
—-Optimal structure and complex assembly lead to the cost rise.
—-All bearings are sourced from global recognized brands,so output torque is more stable.
—Streamlined design,the end of gearbox cover can be opened,easy to install and replace.

Common Problems and Troubleshooting for Worm Gearboxes
Worm gearboxes, like any mechanical component, can experience various issues over time. Here are some common problems that may arise and possible troubleshooting steps:
- Overheating: Overheating can occur due to factors such as inadequate lubrication, excessive loads, or high operating temperatures. Check lubrication levels, ensure proper ventilation, and reduce loads if necessary.
- Noise and Vibration: Excessive noise and vibration may result from misalignment, worn gears, or improper meshing. Check for misalignment, inspect gear teeth for wear, and ensure proper gear meshing.
- Leakage: Oil leakage can be caused by damaged seals or gaskets. Inspect seals and gaskets, and replace them if necessary.
- Reduced Efficiency: Efficiency loss can occur due to friction, wear, or misalignment. Regularly monitor gearbox performance, ensure proper lubrication, and address any wear or misalignment issues.
- Backlash: Excessive backlash can affect precision and accuracy. Adjust gear meshing and reduce backlash to improve performance.
- Seizure or Binding: Seizure or binding can result from inadequate lubrication, debris, or misalignment. Clean the gearbox, ensure proper lubrication, and address misalignment issues.
- Worn Gears: Worn gear teeth can lead to poor performance. Regularly inspect gears for signs of wear, and replace worn gears as needed.
- Seal Wear: Seals can wear over time, leading to leakage and contamination. Inspect seals regularly and replace them if necessary.
If you encounter any of these problems, it’s important to address them promptly to prevent further damage and maintain the performance of your worm gearbox. Regular maintenance, proper lubrication, and addressing issues early can help extend the lifespan and reliability of the gearbox.
Materials Used for Worm Gears
Worm gears are manufactured using a variety of materials to meet different application requirements. Some commonly used materials for worm gears include:
- Steel: Steel is a popular choice for worm gears due to its strength, durability, and wear resistance. It can handle heavy loads and is often used in industrial applications.
- Bronze: Bronze offers good lubricity and is commonly used for the worm gear (worm) component. It provides effective wear resistance and works well in applications where quiet operation is essential.
- Cast Iron: Cast iron is known for its high strength and durability. It’s often used for worm gears in applications where shock loads or heavy-duty conditions are expected.
- Aluminum: Aluminum worm gears are lightweight and corrosion-resistant, making them suitable for applications where weight reduction is important.
- Plastic: Some worm gears are made from plastic materials such as nylon or acetal. These materials are often chosen for their self-lubricating properties and quiet operation.
- Composite Materials: Composite materials can offer a combination of properties, such as lightweight construction and corrosion resistance. They can be suitable for specific applications.
The choice of material depends on factors such as the application’s load, speed, operating environment, and required performance characteristics. It’s important to consider these factors when selecting the appropriate material for worm gears to ensure optimal performance and longevity.
Types of Worm Gear Configurations and Their Uses
Worm gear configurations vary based on the arrangement of the worm and the gear it engages with. Here are common types and their applications:
- Single Enveloping Worm Gear: This configuration offers high torque transmission and efficiency. It’s used in heavy-duty applications like mining equipment and industrial machinery.
- Double Enveloping Worm Gear: With increased contact area, this type provides higher load capacity and improved efficiency. It’s used in aerospace applications, robotics, and precision machinery.
- Non-Throated Worm Gear: This type has a cylindrical worm without a throat. It’s suitable for applications requiring precise motion control, such as CNC machines and robotics.
- Throated Worm Gear: Featuring a throat in the worm, this configuration offers smooth engagement and higher load capacity. It’s used in conveyors, elevators, and automotive applications.
- Non-Modular Worm Gear: In this design, the worm and gear are a matched set, resulting in better meshing and efficiency. It’s utilized in various industries where customization is essential.
- Modular Worm Gear: This type allows interchangeability of worm and gear components, providing flexibility in design and maintenance. It’s commonly used in conveyors, mixers, and material handling systems.
Selecting the appropriate worm gear configuration depends on factors such as load capacity, efficiency, precision, and application requirements. Consulting gearbox experts can help determine the best configuration for your specific needs.
