CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
Standard gearboxes typically cover a rated power range of 0.12 to 315 kW, as per ISO 6336. However, the exact power rating depends on the specific model and application, so always verify with the manufacturer.
Gear ratios for standard gearboxes range from 1.25 to 450, allowing for single or multi-stage reduction. The required ratio depends on the desired output speed and torque for your application.
Housings are often made of cast iron (e.g., HT250) or ductile iron (e.g., QT450), while gears are typically case-hardened steel such as 20CrMnTi or 17CrNiMo6. These materials provide strength and wear resistance.
Selection involves determining the required output torque, input speed, gear ratio, service factor, and environmental conditions. Reference values like those listed (e.g., power, torque, efficiency) are starting points; always consult the manufacturer for model-specific data.
