The planetary gearbox EX series features a compact design and remarkable power, making it an ideal choice for severe duty applications with frequent shock loadings [1, 5, 6]. It provides a wide range of ratios from Min 1/3.48 to Max 1/7000, torque from Min 1000 to Max 700000 Nm, and power from Min 0.47 to Max 1900 kW [5].TheplanetarygearboxEXseriesfeaturesacompactdesignandremarkablepower,makingitanidealchoiceforseveredutyapplicationswithfrequentshockloadings[1,5,6].ItprovidesawiderangeofratiosfromMin1/3.48toMax1/7000,torquefromMin1000toMax700000Nm,andpowerfromMin0.47toMax1900kW[5].
Worm gearboxes incorporate die-casted aluminum components, a ZI teething profile, and modular output flanges, enhancing torsional resistance, structural flexibility, efficiency, and quiet operation [10, 35]. The inline helical gearbox A series features a one-body casting design for increased rigidity and high load capacity, along with optimized oil flow for reduced noise and improved sealing [29].Wormgearboxesincorporatedie-castedaluminumcomponents,aZIteethingprofile,andmodularoutputflanges,enhancingtorsionalresistance,structuralflexibility,efficiency,andquietoperation[10,35].TheinlinehelicalgearboxAseriesfeaturesaone-bodycastingdesignforincreasedrigidityandhighloadcapacity,alongwithoptimizedoilflowforreducednoiseandimprovedsealing[29].
Electric motors are available in three-phase (IE1, IE2, IE3 efficiency) and single-phase options, all being inverter duty, including the brake electric motors T-M series [32, 33]. The company also provides ATEX 2014/34/UE certified explosion-proof gearboxes, offering safety solutions for potentially hazardous environments [2, 7].Electricmotorsareavailableinthree-phase(IE1,IE2,IE3efficiency)andsingle-phaseoptions,allbeinginverterduty,includingthebrakeelectricmotorsT-Mseries[32,33].ThecompanyalsoprovidesATEX2014/34/UEcertifiedexplosion-proofgearboxes,offeringsafetysolutionsforpotentiallyhazardousenvironments[2,7].
