double screw extruder reducer

SZ Specifications 1.Highly Standard Modular Designed  2.High Strength,Compact Dimension  3.Long Service Life  4.Low Noise  5.High efficiency The precision of gear grinding up to DIN5 grade Direction: Co-rotation Screw dia: 35~130 mm Torque range: 0~100,000 N.M Reduction ratio:0~50 Gearbox Reducer for Conical Twin Screw Extruder This series of products use JB/T9050.1-1999 standard production of hard-toothed surface transmission device,which has two parts of the reducer and distribution box.It's special products of conical twin-screw extruder.

1.Highly effective element-analysis equipment Highly effective element-analysis equipment and DIN 5 gear-rating standards are adopted for stress analysis and optimized gear design, minimizing gear-engagement impact and noise for prolonged durability.

2.Hardened gears Made of carburizing steel (Forging), go through normalization heat treatment for forged carburizing steel; and gear faces are also nitride-treated to at least 60HRC hardness for optimal rigidity and carburizing depth 0.8-1.1MM and wear resistance.

3.Super-rigid housing Made of gray cast-iron QT250, tempered to minimize stress, hot deformation, and work well under vibration and impact. 4.Smooth gear-reduction mechanism Featuring gears that mesh precisely, quiet spiral-gear drive for minimal backlash and high torque output.

5.Precision-ground gear surfaces Heat-treated and precision ground for optimal smoothness, delivering precision, quiet and impact-resistant drive for extended gear life. 6.Precision bearing Radial and axial loads have been calculated precisely; Chinese top-quality ZWZ gearbox adopted to ensure extended durability.

7.Meets various critical standards Tested according to critical criteria on advanced instruments, ensuring smooth and precise gear action.

8.Super-hard shaft-seal interface The interface is hardened, precision-ground and hard-chrome-plated to 870HV hardness and Ra 0.8-1.6m roughness, so the shaft-seal is super hard, resists wear and corrosion, and very durable.

9.Precision gearbox Machined with fully-automated CNC borer to ensure exacting concentricity, symmetry, and verticality of bearing orifices for precision gearbox operation.
