Simulation of loading conditions of kinematic pair "driving gear - slewing ring’s crown" in the study of energy intensity of excavator’s slewing mechanism

Abstract

The paper presents the results of calculating kinematic pair of slewing ring of a single bucket excavator and distribution of the load over its contact surface. On the basis of studying loading conditions of a slewing ring with maximum values of inertia which appears in quick acceleration and braking, it is determined that peak voltages, appearing in teeth’s engagement, contribute to decrease of durability.
