Twin screw extruder parts extruder gearbox for extrusion
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.

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 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.
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.
