Series 25Step 8:Calculating thermal powerThe thermal power PT of a gear unit is the power that can be transferred with the gearunit without the oil temperature exceedi ng the calculated maximum value depending onthe lubricant used. To determine the thermal power PT of the gear unit, it is necessaryto determine the thermal limit rating PTH of the gear unit while taking the ambienttemperature into account ( section "Thermal limit rating" ). In addition, the altitudefactor f1 ( table altitude factor f1), the factor for the input speed fn1 ( table factor fn1)and the factor for the installation site fV ( table factor fV) are required.PT = 45.6 kW x 0.95 x 1.0 x 1.29Result:PT = 43.32 kWHigher thermal powers are possible if syntheti c lubricants and special oil seals are used.Please contact SEW-EURODRIVE in such cas
