Methodology for the monitoring and analysis of the mining truck transmission system as a decision tool for maintenance

Abstract

Introduction: The transmission system of mining vehicles is one of their most important components. This system is subject to various operating conditions (for example: overheating, fatigue, fracture and wear, etc.) that can generate transmission failure producing loss of availability. Because of this, it is of vital importance to establish the operational conditions of the equipment, based on the information provided by a fault diagnosis and alert system, in order to determine the appropriate monitoring and control plans, prolonging the life of the components.

Objective:The goal of this paper is to develop a methodology in order to analysis of the behavior of mining truck transmissions in the operating state. Its purpose is to establish, in accordance with the current laws of the component, a possible remaining life in which it is determined if it is within permissible ranges or if on the contrary actions mustbe taken that guarantee an acceptable life cycle.

Methodology:This article shows the analysis of the methodology for the analysis and diagnosis of the component, divided into fourstages: (i) establishment of permissible operational limits for analysis of oil conditions; (ii) generation of model change matrix; (iii) analysis of events or failures associated with the transmission; and (iv) improvement of the component's useful life.

Results: Through the application of the methodology, it was possible to determine the main causes of transmission failures and their relationship with the operational parameters analyzed.

Conclusions: The research seeks to generate results in real time that facilitate the organization of the preventive and corrective activities of the component, necessary for the operation of the same.
