2 f u DESCH Denox Panetary Gearboxes features High power density due to optiu utiisation of space by eans of power distribution aong up to panetary whees per gearbox eve High efficiency oaxia design and rotationa syetry enabe turnabe arrangeents and use as overriding, distribution and suation gearbox Insusceptibe to shoc aso for pea deands of the sae ange ooth running due to the appropriate seection of the toothing data, exact production and ow reative speeds DE H has been constructing and continuousy deveoping panetary gearboxes since. The gearboxes are used wordwide in the ost different appications. DE H s expertise in design and operation is the basis for the new DE H Denox gearbox series. DE H Denox panetary gearboxes consist of the coaxiay arranged coponents sun gear, panet carrier and gear ri and the turnabe panetary whees aigned at a constant axis distance in the panet carrier. Mutipe stage gearboxes are created by connecting this toothing arrangeent in series. 2 The DE H Denox gearbox series aso fors a patfor for specia designs adapted to specific appications. Apart fro the cobination of various panetary gearbox stages, further designs are possibe with input beve gear, spur gear or wor gear stages. DE H panetary gearboxes can aso be fitted with one or ore shifting gear stages, if required. The shifting happens echanicay, eectricay or hydrauicay. Adaptabe to extreey difficut space requireents due to anifod cobination options with beve gear, spur gear and wor gear stages, as we as custoised achine connections ositionay independent with appropriate oi fiing or appropriate arrangeent of forced oi ubrication Low oents of inertia for highy dynaic drives Variabe speeds due to shifting stages acuated fatigue-free toothing when subjected to the axiu cataogue torques. The cacuated roer bearing service ife is,000 operating hours at fu capacity.

4 f u Design Sizes Toothing The Denox gearbox series is avaiabe in s and therefore covers a torque The sun pinions and panetary whees are case-hardened and ground. The gear ris are tepered and nitrided. The rectiinear spur gear invoute face toothing has an pressure ange of. The toothing of the Denox gearboxes is cacuated as fatigue-free when subjected to the axiu torques specified in the cataogue. range of,0 N to,000 N. The transission ratio range stretches fro i = to i = 2,33. Further transission ratios can be found in the standard transission ratios tabe on page. Higher torques and divergent transission ratios are possibe on request. The oduar design of the gearboxes resut in a high degree of standardisation due to recurrent coponents and gear box eves. Gearbox designs Apart fro the cobination of various panetary gearbox stages, further designs are possibe with input beve gear, spur gear or wor gear stages. Various cobination options are iustrated on page 3. Materias Ony roer bearings of sufficient are used for supporting pinion shafts, panetary whees and panet carriers. At a drive speed of 1,0 rp,000 operating hours under fu capacity are cacuated.

Besides the standard hoow output shafts for shrink disc connections, hoow shafts or soid shafts with spined toothing according to DIN are possibe too. Seas Drive and output shafts are seaed as a standard with radia shaft sea rings. Materias are seected according to the appication. Depending on the appication, the gearboxes ay be equipped with axia face seas or regreasabe, contact-free abyrinth seas.
