Technical data - Helical-worm gearboxesStart-up efficiencyDuring start-up, the start-up efficiency A of a helical-wormgearbox is lower than its operative efficiency at ratedspeed.The start-up efficiency A must therefore always beconsidered when starting under load.The start-up efficiency is determined by the oil temperatureand the degree to which the tooth faces have been run-in.The values given in the tables are theoretical values andare valid with a tolerance of ± 10%.RatioStart-up efficiencyiratedA5.6 0.718 0.719 0.6710 0.7111.2 0.7112.5 0.6714 0.7116 0.6718 0.6720 0.5522.4 0.6725 0.5528 0.6731.5 0.5535.5 0.67RatioStart-up efficiencyiratedA40 0.5545 0.6750 0.5556 0.5563 0.5571 0.5580 0.5590 0.55100 0.55112 0.55125 0.55140 0.55160 0.55180 0.55200 0.557G-motion const en 11/20047-5
