Gearbox for Extruder

Specialized gear reducers equipped with a thrust bearing, designed for screw extruders used in processing plastics and rubber. These high-precision units have hardened tooth surfaces and are designed for reliable operation under high loads.

Available series:

• ZLYJ series: Specialized gearboxes for standard extruders.
• DJYG series: High-torque extrusion gearboxes.
• SZ series: Gearboxes designed for twin-screw extruders.
• R, S, K, F series: Geared motors (with hardened tooth surfaces)
• TB, TBR, TAE, TAER, TVB, TVBR, TD, TDR series: Precision helical planetary gearbox.

A wide range of gearboxes for the main drive of extruders and pelletizers:

ZLYJ: 112, 133, 146, 173, 200, 225, 250, 280, 315, 330, 375, 420, 450, 560, 630.

DJYG: 133, 146, 160, 180, 200, 225, 250, 280, 320, 360

SZ: 45, 50, 55, 65, 80, 92
in various versions.

Gear ratio 6.3:1, 8:1, 10:1, 12.5:1, 14:1, 16:1, 18:1, 20:1, 33:1

 

Technical features and advantages:

Reliable materials: Shafts and gears are made of high-strength alloy steel.

Gear durability: The gears undergo special processing, including carburizing, hardening and grinding.

Strength and precision: Gear hardness reaches HRC54-62. Gear accuracy corresponds to level 6 (per standard GB10095-88).

Axial load protection: A large thrust bearing is installed in the front part of the hollow output shaft. It effectively withstands the axial pressure of the screw during operation.

Operating efficiency: The units feature compact dimensions and a high load-bearing capacity. They provide smooth transmission, low noise and high efficiency.
