iffen, die geruschdmpfenden Gehuse mit MASAK-Rechenprogramm entwickelt und auergewhnlich hohe berdeckungs-grade der Verzahnung erreicht. Temperaturverhalten FLENDER-Zahnradgetriebe haben bei einemguten Wirkungsgrad ein gnstiges Tempera-turverhalten, weil die Gehuseoberflchen vergrert wur- den, berwiegend berhrungsfreie Labyrinth-dichtungen eingesetzt werden knnen und groe Lfter mit einem neu entwickeltenLuftleitsystem zur Anwendung kommen. Bei der Auswahl von FLENDER-Zahnradge- trieben wird eine niedrige maximale ltem- peratur zugrunde gelegt. Die Betriebssicher-heit wird dadurch erhht, und der Wartungs-aufwand verringert sich durch lngere -standszeiten.Design FLENDER gear units are completely new design. Outstanding innovations are: more sizes with reduced variety of parts; higher operational reliability combined with increased power capacity; predominantly non-contacting wear-resis-tant labyrinth seals possible; flanged output shafts to facilitate assemblyof gear units in confined spaces. Mounting position FLENDER gear units can be supplied for hori- zontal installation.The following inclinations are possible withoutany additional measures, with the exceptionof the adjustment of the oil quantity andthe length of the oil dipstick: longitudinal 5 lateral 2 Other arrangements are also possible on request. Motor bell housings, gear unit swing-bases,and torque supports are part of our standard product range. Noise behaviour New concepts were applied to clearly improve the noise emission of the FLENDER gear unitsby grinding the bevel gears; designing noise-absorbing housings by means of the MASAK computing program; and achieving exceptionally large contact ratios. Thermal conduction FLENDER gear units not only have high effi- ciency but also favourable thermal con- duction through enlarged housing surface areas; because non-contacting labyrinth seals can be used; and because large fans incorporating new type of air conduction fan cowl are being used.
