Evaluation of the Open Pit Vehicles Loading Influence on the Reliability of Motor - Wheel Reducers

摘要

The purpose of the work is to increase efficiency in the use of dump trucks in open pit mining by improving operational reliability, reducing bounce rates, reducing the length of the vehicle repairing and, as a result, the cost of the final product. The article describes how to improve the reliability as well as the efficiency of the use of trucks operating in open-pit mining. The work's result is the methodology that allows defining of the loading reliability of all vehicles. The study is based on the data obtained experimentally in real conditions of operating trucks. During the processing of the experimental data, regression dependences were obtained of the oil temperature in the gears of the motorized wheels of quarry trucks on the factors that characterize the operating conditions. Also, the degree of influence of each of the said factors on the oil temperature was assessed. Sub-sequently, using the obtained dependences, the practical problem of determining the length of vehicle repair was solved. This work has a great scientific and practical importance because the results can determine the rational values of loading of dump trucks used in open pit mining, measuring the operating conditions.
