Product Description

Advantages of Extruder Gearboxes

High torque capacity: This is their most critical advantage. The extrusion process involves pushing sticky or solid materials through a confined die, which requires tremendous force. Extruder gearboxes are designed with rugged gears and bearings to withstand sustained, ultra-high torque loads.

Excellent axial thrust load handling: The extruder screw generates enormous axial (longitudinal) forces as it pushes the material forward. Extruder gearboxes use unique, dedicated heavy-duty thrust bearings (usually spherical roller thrust bearings, sometimes stacked bearings) that absorb and manage these extreme axial loads, protecting the motor and other parts of the gearbox.

Precise speed reduction and control: They precisely reduce the high speed of the motor to the lower, controllable speed required by the extruder screw. This allows the extrusion process to be finely tuned, ensuring consistency in product size, surface finish, and overall quality.

Rugged construction: Designed for continuous operation under harsh conditions (high temperatures, high pressures, heavy loads), these gearboxes feature heavy-duty housings (often with ribs) and high-quality, heat-treated and precision-ground gears to ensure a long, reliable service life.

Efficient power transmission: Even with high loads, well-designed extruder gearboxes maintain high efficiency, minimize energy losses, and help reduce operating costs.

Optimized cooling and lubrication systems: Given the high temperatures and internal friction generated by the extrusion process, extruder gearboxes are often equipped with advanced lubrication systems (e.g., forced oil circulation via pumps and heat exchangers) to regulate operating temperatures and ensure optimal performance and service life for gears and bearings.

Synchronization (for twin-screw extruders): In twin-screw extruders, the gearbox is also responsible for precisely synchronizing the rotation of the two screws, preventing collisions and ensuring uniform mixing and processing of the material.

1, The gear is made of high-strength low-carbon alloy steel by carburizing and quenching. The hardness of
the tooth surface is up to HRC58-62. The gears are groun d grinding technology with high precision and
good contact.
2, High transmission efficiency: single stage is greater than 96.5%, double level is greater than 93%, third
level is greater than 90%.
3, Smooth operation and low noise.
4, Small size, light weight, long service life and high carrying capacity.
5, Easy to disassemble and easy to install.
