Speed Ratio: 10–112
Max. Output Torque: 85 kN·m
2.1 Professional Parameter Matching for Single Screw Extrusion
The HE series covers a wide power range of 0.75kW to 315kW and a dedicated speed ratio range of 10 to 112, perfectly matching the low-speed high-torque operation characteristics of various small, medium and large single-screw extruders. The scientific speed ratio setting fully meets the precise feeding, uniform extrusion and stable speed regulation requirements of plastic extrusion, granulation, modified material processing and rubber production equipment. It avoids power surplus or torque insufficiency caused by universal reducer mismatching, realizing professional and targeted equipment supporting.
2.2 85kN·m Ultra-High Torque & Excellent Overload Resistance
With a maximum output torque up to 85kN·m, the HE single-screw dedicated reducer provides sufficient and stable torque reserve for long-term extrusion operation. Core transmission components are made of high-strength wear-resistant alloy materials, processed through strict carburizing, quenching and precision grinding technology. The optimized meshing structure realizes uniform force bearing, which can effectively resist material extrusion resistance, instantaneous overload and continuous alternating load during equipment operation. It maintains stable torque output without jitter, slipping or power attenuation, ensuring consistent extrusion thickness and uniform product quality.
2.3 Low Backlash & High Extrusion Precision
Aiming at the precision extrusion demand of polymer materials, the HE series adopts optimized gear clearance control and anti-backlash design. The transmission clearance is effectively reduced, realizing sensitive speed response and accurate torque output. It effectively avoids material accumulation, uneven discharging and dimensional deviation caused by transmission hysteresis, greatly improving the finished product precision and yield of extrusion equipment, and meeting the high-precision production requirements of high-end plastic products.
2.4 Continuous Heavy-Load Operation & Low Heat Generation
The optimized composite transmission structure reduces internal friction loss and heat generation. The whole machine is equipped with an efficient heat dissipation structure, which can quickly export heat generated by long-term full-load operation. It supports 24-hour uninterrupted continuous extrusion production, effectively solving the problems of high temperature rise, easy oil deterioration and gear wear of traditional extruder reducers. It features strong operational stability and anti-fatigue performance, adapting to high-intensity industrial production rhythm.
2.5 High Structural Rigidity & Durable Sealing Performance
The integral thickened housing undergoes professional stress relief treatment, with strong overall rigidity and anti-deformation ability, avoiding structural displacement under long-term heavy-load vibration. Adopting upgraded multi-layer sealing structure, it has excellent oil leakage resistance, dust-proof and anti-pollution performance. It can operate stably for a long time in dusty production workshops and continuous processing environments, with low failure rate and long service life.
2.6 Easy Installation & Low Comprehensive Maintenance Cost
The HE series adopts standard mounting size and universal interface specially designed for single-screw extruders, with high compatibility with mainstream extrusion equipment in the market. It supports fast assembly and replacement without complex equipment modification. The mature and reliable internal structure has fewer vulnerable parts, and daily maintenance and oil replacement are simple and convenient, effectively reducing equipment downtime and long-term operation and maintenance costs.
Relying on the comprehensive advantages of professional extrusion matching, super-high torque output, high precision stability and continuous heavy-load resistance, GUOMAO HE series single-screw dedicated reducers are widely used in plastic extrusion and polymer material processing industries:
3.1 Plastic Extrusion Machinery: Single-screw plastic extruders, film extrusion equipment, pipe extrusion machines, profile extrusion molding equipment, meeting stable and precise extrusion production requirements.
