Abstract

A coupling system between an operating machine and a planetary gearbox. The coupling system comprising an axially rotatable machine shaft of an operating machine; and a slow gearbox shaft of a planetary gearbox connectable integrally in rotation with the machine shaft in an operational configuration. The machine shaft and the slow gearbox shaft comprise a first coupling portion and a second coupling portion, respectively, substantially truncated cone-shaped and complementary to each other, the first coupling portion and the second coupling portion being conically coupled to each other in the operational configuration.

Abstract

The method for testing the life-time of gear drives and the like provides for prearranging the calculated life-time for a gear drive (1) to be tested, prearranging a scale model of said drive (1) to be tested according to a determined scale ratio, predetermining a desired testing time shorter than said calculated life-time. The method further provides for calculating equivalent operating conditions to be applied to said scale model during said desired testing time, suitable to determine, upon calculation, the same risk of damage determined by the design operating conditions of the said drive (1) to be tested. Finally, the equivalent operating conditions are applied to the scale model, and the damage condition thereof is monitored.
