...Andrzej Kawalec; Jerzy Wiktor At the beginning of gear transmission design, mainly simplified methods of gear strength analysis based on ISO or AGMA standards are used. However, they allow for calculation of approximate and sometimes biased stresses. Moreover, ISO standard is generally focused...

... standards tooth-root stresses are calculated for the unit nominal load. The load in the plane of action normal to the tooth flank is converted to the nominal tangential load at the reference diameter F t (ISO standard) or to the transmitted tangential load at the operating pitch diameter F w...
