GUOMAO JE High Load Series Single Screw Extruder Reducer
The GUOMAO JE High Load Series Single Screw Extruder Reducer is a newly upgraded heavy-duty professional transmission gearbox independently optimized for high-load, long-cycle continuous operation of single-screw extrusion equipment. Adopting high-precision hard-tooth helical gear transmission structure, high-strength alloy steel heat treatment process and built-in high-load thrust bearing assembly, this series features wide power and speed ratio coverage, 40kN·m stable heavy torque output, strong axial thrust resistance, low-temperature continuous operation and ultra-high operational stability. Targeted at the harsh working characteristics of high pressure, large axial impact and 24-hour uninterrupted operation of plastic and rubber extrusion production lines, it effectively solves the common defects of traditional extrusion reducers such as insufficient load capacity, easy heat generation, unstable discharging and short service life. With professional extrusion working condition customization and excellent heavy-duty performance, it has become a high-cost-performance core supporting product for medium and high-end single-screw extrusion equipment.
Power (kW): 8–400kW
Speed Ratio: 6.3–28
Max. Output Torque: 40 kN·m
The JE high-load series covers a wide power range of 8kW to 400kW and a professional extrusion-specific speed ratio range of 6.3 to 28, perfectly matching the low-speed high-torque operation logic of various small, medium and large single-screw extruders. The optimized speed ratio portfolio balances high-speed feeding and high-pressure extrusion, avoiding the problems of insufficient extrusion pressure at high speed and low production efficiency at low speed of ordinary reducers. It fully adapts to the process requirements of plastic granulation, pipe profile extrusion, film blowing and rubber molding, realizing one machine for multiple working conditions and strong universal matching performance.
2.2 40kN·m Super High Torque & Strong Axial Thrust Resistance
With a maximum output torque of 40kN·m, the JE series provides sufficient and stable heavy-load power reserve for high-pressure extrusion working conditions. Core gears are made of high-quality alloy steel, processed through strict carburizing, quenching and precision grinding, with tooth surface hardness up to HRC58-62 and Grade 6 high precision. Equipped with a customized large-size high-load thrust bearing structure at the front end of the hollow output shaft, it can independently bear the huge axial back pressure generated by screw extrusion, effectively preventing shaft displacement, transmission jitter and material backflow. The uniform multi-tooth meshing structure resists instantaneous material impact and long-term alternating load, ensuring stable torque output without attenuation during full-load operation.
2.3 Upgraded Heat Dissipation System & Long-Term Anti-Fatigue Operation
Different from ordinary reducers, the JE high-load series is equipped with an optimized circulating forced lubrication and heat dissipation system, which rapidly exports internal heat generated by 24-hour continuous high-pressure extrusion operation. It effectively solves the industry pain points of excessive temperature rise, oil deterioration and accelerated gear wear of traditional extrusion reducers under long-cycle working conditions. The low-friction transmission structure reduces internal power loss, ensuring stable mechanical performance and anti-fatigue ability in long-term high-intensity production, greatly extending the overall service life of the equipment.
2.4 High Transmission Precision & Stable Extrusion Quality
Through professional tooth profile correction and precise meshing clearance control, the JE reducer achieves ultra-low transmission backlash and sensitive speed response. It completely avoids product dimensional deviation, uneven discharging and material accumulation caused by transmission hysteresis and operation jitter. The high-precision assembly process ensures low runout of the output shaft, making the extrusion thickness uniform and product molding stable, fully meeting the high-precision production requirements of high-end plastic films, pipes, profiles and modified materials.
2.5 High Rigidity Structure & Excellent Sealing Performance
The whole machine adopts integral thickened high-rigidity cast iron housing with secondary stress relief treatment, which eliminates internal structural stress and effectively resists deformation and vibration displacement under long-term heavy-load vibration. Adopting upgraded multi-layer combined sealing structure, it has superior high-temperature resistance, dust-proof and oil-leakage-proof performance. It can operate stably for a long time in high-temperature, dusty and continuous processing workshops, adapting to harsh industrial production environments with ultra-low failure rate.
2.6 Flexible Installation & Low Comprehensive Operating Cost
The JE series adopts standard universal mounting interface for extrusion equipment, supporting diversified installation methods and multiple input and output forms. It is highly compatible with mainstream single-screw extruders in the market, realizing fast assembly and old equipment replacement without complex structural modification. The standardized modular structure reduces vulnerable parts, simplifies daily lubrication and maintenance procedures, effectively reducing equipment downtime and long-term operation and maintenance costs, with outstanding comprehensive cost performance.
Relying on the comprehensive advantages of high-load torque resistance, strong axial thrust bearing capacity, constant temperature stable operation and high-precision transmission, GUOMAO JE high-load series reducers are widely used in various single-screw extrusion and new material processing fields:
3.1 Plastic Profile & Pipe Extrusion: Plastic pipe extruders, door and window profile molding equipment, plate and sheet extrusion machines, ensuring uniform extrusion and stable molding of plastic products.
3.2 Film & Packaging Material Equipment: Blown film machines, packaging film extrusion lines, thin-wall material processing equipment, adapting to high-precision and stable continuous production requirements.
3.3 Modified & Recycled Material Processing: Plastic modified granulators, waste plastic recycling extrusion equipment, composite material processing machinery, resisting long-term high-resistance heavy-load operation.
3.4 Rubber & New Material Machinery: Rubber strip and hose extruders, polymer new material molding equipment, degradable material processing lines, meeting high-pressure and anti-impact extrusion working conditions.
3.5 Wire and Cable Extrusion Industry: Cable insulation layer and sheath extrusion equipment, high-speed cable molding machinery, ensuring uniform coating thickness and stable product quality.
The GUOMAO JE High Load Series Single Screw Extruder Reducer is an upgraded high-performance heavy-duty transmission product tailored for high-load extrusion working conditions. It integrates 40kN·m high torque output, strong axial thrust resistance, constant temperature long-cycle operation and high-precision stable transmission, making up for the insufficient load capacity and poor durability of traditional extrusion reducers in high-intensity production scenarios. With mature heavy-duty manufacturing technology, stable batch quality and complete after-sales service system, it is the preferred reliable supporting solution for medium and high-end single-screw extrusion equipment upgrading and standardized matching.
