TOPLINE Launches Hightorque Extruder Gearbox for 300900 RPM Range

In precision manufacturing lines, high-performance extrusion equipment operates with remarkable efficiency, transforming raw materials into high-value products. Behind this process lies a critical yet often overlooked component—the gearbox. Serving as both a power transmitter and a cornerstone of stable operation, gearbox technology determines the ultimate performance of extrusion systems.

Twin-screw extruders, indispensable in polymer processing, food production, and biotechnology, rely on synchronized screw rotation. The gearbox acts as the system's "brain" and "heart," enabling precise control over three critical functions:

• Power Transmission & Speed Regulation: Converting motor output to the required screw rotation range (300-900 RPM) while matching process-specific requirements.
• Torque Amplification: Overcoming material resistance, particularly with high-viscosity or filled compounds, to prevent clogging and maintain consistent throughput.
• Precision Synchronization: Maintaining exact inter-screw clearance through controlled co- or counter-rotation, directly impacting product quality.
• Operational Reliability: Engineered for continuous high-load operation through advanced materials, lubrication systems, and structural design.

The gearbox utilizes 304 stainless steel housing for corrosion resistance and hygienic applications, while internal components employ alloy steel subjected to carburizing, quenching, and tempering processes. Precision machining ensures dimensional accuracy with surface finishes minimizing friction losses.

• Triple-Parallel Shaft Design: Increases torque capacity by 30-40% compared to conventional configurations
• Modular Housing: Standardized unibody construction allows flexible adaptation to diverse extruder configurations
• Ground Gear Technology: Sub-micron surface finishes achieve 99.7% meshing accuracy for vibration reduction

• Torque density: 18-22 Nm/kg across operational range
• Transmission efficiency: 94-98% (varies by reduction stages)
• Noise levels: ≤75 dB at 1m distance under full load
• Service life: ≥60,000 hours under normal operating conditions

The TL series serves diverse sectors requiring precision extrusion:
