Screw Extruder Gearbox

Screw Extruder Gearbox Introduce

Screw Extruder Gearbox is a key component of an extruder. It is mainly used to connect the motor and the screw, converting the high-speed rotation of the motor into the low-speed and high-torque rotation required by the screw, thereby realizing the process of material transportation, melting, mixing, pressurization, and extrusion. It is widely used in extrusion molding equipment in industries such as plastics, rubber, food, and chemical engineering.

Some details:

1. ZLYJ gearbox of 112-146 is Natural cooling, 173-250 is Coil cooling, 225-250 is Cooler Cooling with pump. the material of
the cooling tube is pure bronze. ( with a cooling tower or not)
2. The whole gear material is cast iron, Gear material: high alloy steel low carbon (20CrMnTi), the surface is carburized case up to
0.7-1.1mm, surface hardness is HRC58-64, the accuracy of gear is GB10095-88-5 standard. gear craft is (gear grinding)
3. Our bearing is Tapered Roller Bearings( china top brand ZWZ gearbox oil seal)
4. There are several normal ratios: 8,10,12.5,16,20, depends on customers requirements.
5. Various seal forms and perfect oil leak-proof function. (Taiwan NAK brand gearbox oil seal)

1.High Torque Transmission Capacity: High-strength gear and shaft materials, as well as optimized gear design and transmission structures, are adopted, enabling it to bear and transmit large torque. This ensures that the screw obtains sufficient power during the extrusion process and can meet the needs of high-viscosity materials or high-volume extrusion.

2.Good Axial Load Capacity: It is equipped with special axial thrust bearings, which can effectively bear the axial force generated by the screw during the extrusion process, ensuring the stable operation of the gearbox and the screw, and preventing component damage and equipment failure due to excessive axial force.

3.Precise Transmission Ratio Control: Through precisely designed and manufactured gear pairs, accurate transmission ratio control can be achieved, thereby precisely controlling the rotational speed of the screw to meet the requirements of different materials and processes for extrusion speed and output, and ensuring the stability and consistency of product quality.

4.High Temperature Resistance: During the extrusion process, the gearbox may be affected by high temperatures. The Screw Extruder Gearbox usually uses high-temperature-resistant grease and sealing materials and has a good heat dissipation structure, such as heat sinks and cooling channels, enabling it to operate stably for a long time in a high-temperature environment.

5.Compact Structural Design: The overall structure is compact and has a small volume, achieving efficient transmission functions within a limited space. It is convenient for integrated installation with other parts of the extruder and is suitable for extrusion equipment of various structures and sizes.

1.Improved Production Efficiency: High torque transmission and precise transmission ratio control enable the screw to operate at a relatively high rotational speed and stable torque, thereby increasing the extrusion speed and output of materials, effectively improving production efficiency, and reducing production costs.

2.Extended Equipment Service Life: Good axial load capacity and high-temperature resistance reduce the risk of wear and damage to key components such as gears and bearings, lower the failure rate of the equipment and maintenance costs, and extend the service life of the entire extrusion equipment.

3.Ensured Product Quality: Precise transmission ratio control and stable operation performance can ensure the uniformity and stability of materials during the extrusion process, making the dimensional accuracy, physical properties, and other indicators of extruded products more consistent, thereby improving product quality and pass rate.

4.Reduced Energy Consumption: Optimized gear design and transmission structure, as well as a good lubrication and heat dissipation system, result in less energy loss during the operation of the gearbox, thereby reducing the energy consumption of the motor and achieving energy-saving effects, which meets the requirements of energy conservation and emission reduction.

5.Easy Maintenance and Servicing: The compact structural design makes the internal structure of the gearbox relatively simple, making it easy to conduct daily inspections, maintenance, and servicing. Meanwhile, the use of standardized parts and reasonable installation methods facilitates quick repair and component replacement by maintenance personnel, reducing equipment downtime.
