Abstract
A comparative analysis of the main types of power equipment and transmissions of drives for running equipment for quarry vehicles was performed. The interrelations of the constructive schemes of drives of running equipment with traction class and carrying capacity of quarry vehicles are shown. Dependence of diesel engine power on air temperature and atmospheric pressure is revealed. An analysis of design schemes of transmissions of running equipment is given. Based on the evaluation of the design schemes, the directions for improving the drives of running equipment for quarry vehicles are given. As a result of the analysis of various types of drives and power equipment, it was revealed that when assembling the base machine, an individual approach should be applied.
Highlights
The development of an open method for the development of mineral deposits is accompanied by an increase in the scale of production and volumes of transportation of rock mass, an increase in the depth of quarries, an increase in the share of semi-rocky and rocky rocks, and the complication of mining technical conditions for mining equipment.The manifestation of negative trends in the mining sectors of the economy causes the growth of material and energy costs in the extraction of minerals, and the specific weight of the costs of transporting the mountain mass increases at an accelerating rate
The purpose of the research is to increase the efficiency of functioning of a career motor transport
The object of the research is the constructive schemes of the drives of running equipment for quarry vehicles
Summary
The development of an open method for the development of mineral deposits is accompanied by an increase in the scale of production and volumes of transportation of rock mass, an increase in the depth of quarries, an increase in the share of semi-rocky and rocky rocks, and the complication of mining technical conditions for mining equipment. The manifestation of negative trends in the mining sectors of the economy causes the growth of material and energy costs in the extraction of minerals, and the specific weight of the costs of transporting the mountain mass increases at an accelerating rate. The share of "transportation" costs reaches 50-60%, and at a depth of the quarry 250 m and more - 65-70%. In connection with the current situation, the problem of increasing the efficiency of mining equipment operation due to the creation of new technical level machines with reduced material and energy consumption and environmentally friendly is becoming topical
