Det Norske Veritas provides with the standard No. 41.2 "Calculation of gear rating for marine transmission" a widespread gear calculation method for marine purposes, such as marine propulsion and important auxiliary onboard ships and mobile offshore units. In KISSsoft, thecylindrical and bevel gear calculation were implemented, according to edition of May 2012 (module ZA19 and ZC11). The standard contains not only the safety calculations for root and flank fatigue but also the safety calculation for achieving a required hardening depth. This valuable information is now available in KISSsoft for other calculation methods too. Another special feature is the detailed material properties in limited life strength and the possibility to consider peak loads.
