Dynamics Characteristics Analysis of Rotary Reducer Assembled Hydraulic Motor in Excavator

Abstract

This paper presents the analysis of the structure and the gear contact load in the gear reducer used in slewing hydraulic motor system of an excavator. The parameterized structure model of reduction drive assembly is established by using UG software, and the model is imported to the LMS. Virtual.lab software to form dynamics mode, then based on the theory of gear contact load and ANSYS analysis means, the dynamics performance analysis of reducer assembly is completed. The paper provides an analysis platform and theoretical guidance for the design of excavator slewing system.
