FEATURES (Gearbox for Extruder)
1.Highly effective ANSYS element-analysis
ANSYS Workbench and AGMA 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 tempered nickel-chromium-molybdenum steel with hardness of 28HRC; and gear faces are also nitride-treated to 58HRC hardness for optimal rigidity and wear resistance.
3.Super-rigid housing
Made of gray cast-iron FC25, 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; top-quality SKF or NSK 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 1000HV hardness and Ra 0.2μm 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.
