“…The rational value of the the load-carrying capacity coefficient with considering the temperature mode of the MWR and operating conditions is selected at the minimum of unit costs which taking into account the productivity and reliability of mine dump trucks. The number of failures is reduced by 25,7%, the cost of repairing the MWR by 20,8%, the temperature of the MWR oil by 3,21% (from 140,4 ° С to 135 ° С) when decreasing the load-carrying capacity coefficient to 0,8 [3][4][5][6][7][8][9][10][11][12][13][14][15][16].…”

Abstract. The article discusses the impact of operational factors on the reliability of reducers for motor-wheels of mine dump trucks, the consequences of oil overheating in the reducer are determined. As a result of the research, the degree of influence of various factors on the oil temperature and the dependence of the oil temperature on the coefficient of load capacity have been determined. And also dependence of expenses on repair of reducers of motor-wheels from loading of a dump truck.

“…The height of the trochoid of the electron drift motion (during the generation of ions in the diode with magnetic self-insulation) is comparable with the height of the layer of the electrons' drift in the diode with an external magnetic insulation, where a high efficiency of the PIB generation was achieved. 4 In our experimental conditions, the thickness of the drifting electrons is less than 0.5 mm. The thickness of a skin layer in the grounded electrode, which is made from stainless steel, is 0.12 mm for the current frequency of 2.5 MHz (the current pulse duration is 200 ns, see Fig.…”

“…For a total ion beam energy of 80-90 J per pulse, up to 500 J is required from the magnetic field source. 4 In 1977, Humphries 5 first suggested the construction of an ion diode with magnetic self-insulation. A transverse magnetic field is formed in the A-K gap by the diode self-current when the current flows along the electrodes.…”

The results of a study of the generation of a pulsed ion beam of gigawatt power formed by a diode with an explosive-emission potential electrode in a mode of magnetic self-insulation are presented. The studies were conducted at the TEMP-4M ion accelerator set in double pulse formation mode: the first pulse was negative (300-500 ns and 100-150 kV) and the second, positive (150 ns and 250-300 kV). The ion current density was 20-40 A=cm 2 ; the beam composition was protons and carbon ions. It was shown that plasma is effectively formed over the entire working surface of the graphite potential electrode. During the ion beam generation, a condition of magnetic cutoff of electrons along the entire length of the diode (B=B cr ! 4) is fulfilled. Because of the high drift rate, the residence time of the electrons and protons in the anode-cathode gap is 3-5 ns, while for the C þ carbon ions, it is more than 8 ns. This denotes low efficiency of magnetic self-insulation in a diode of such a design. At the same time, it has been experimentally observed that, during the generation of ion current (second pulse), the electronic component of the total current is suppressed by a factor of 1.5-2 for a strip diode with plane and focusing geometry. A new model of the effect of limiting the electron emission explaining the decrease in the electronic component of the total current in a diode with magnetic self-insulation is proposed.

“…First, we compared the results of two methods (current density + voltage, and using the infrared imaging) for the beam formed by an applied B r magnetically insulated ion diode [15]. The experiments were carried out using the TEMP-4M accelerator configured in single pulse mode suitable for this diode.…”
