Justification and selection of design parameters of the eccentric gear mechanism of the piston lubrication and filling unit for the mining machines maintenance

Article preview

Piston pumps are widely used in the lubrication systems of mining machines. When carrying out technical maintenance (MOT), including lubrication and filling works, at the site of operation of mining machines due to the remoteness from repair shops and warehouses of fuels and lubricants (FAL), mobile repair shops ( MRS), maintenance units (MU) and mechanized filling units (MFU) are used. The specificity of carrying out maintenance is to create conditions for the supply of oils, working fluids and lubricants to the corresponding systems of mining machines for their refueling. Existing piston pumps and pumping units, as a rule, are single-flow, and the piston is driven by a crank mechanism driven from the engine through a worm gear. The emergence of unique, hydraulic, low-mobility mining machines in open pit mining required a significant increase in the power of the MU and MFU oil pumping units, primarily for greases. However, the traditional design of the drive design of a crank-type piston pump unit at a power of over 80 kW does not allow achieving the specified operating time, it is accompanied by intensive wear of the drive elements and increased dynamics during operation. In addition, it is necessary to apply various designs of pumping units for the supply of liquid and grease lubricants. Thus, it is necessary to develop new circuit solutions for pumping units of the crank type, to improve mobile refueling facilities with a modernized design of the pump unit drive of the mobile lubrication and filling station MRS.

Promising model range career excavators operating time assessment in real operating conditions

Article preview

The development prospects of the mining industry are closely related to the state and development of modern mining machinery and equipment that meet the technical and quality requirements of mining enterprises. Enterprises are focused on a quantitative assessment – the volume of mineral extraction, depending on the functioning efficiency of a promising series of mining machines, which include modern mining excavators. Downtime and unplanned shutdowns of mining excavators directly depend on the operating conditions of the mining machine, which has negative influence on the machine as a whole and its technical condition, which entails a decrease in the efficiency of using expensive mining equipment and economic losses of the mining enterprise. The rationale for external factors that affect the operating time and technical condition of mining excavators is given. For a more detailed assessment of the influence of external influences on the efficiency of operation of mining machines, the influencing factors are divided into two groups: ergatic, directly related to human participation, and factors of a natural-technogenic nature, where human participation is minimized. It was revealed that factors of a natural-technogenic nature have the greatest influence. An algorithm is proposed for a comprehensive assessment of the technical condition and forecasting of operating time both in nominal and in real operating conditions, taking into account factors of a natural and technogenic nature. It is proposed, based on the developed program for planning and evaluating the life of a mining excavator, to adjust the schedules for maintenance and repair (MOT and R) in order to minimize the number of unplanned downtime of a mining excavator and maintain it in good condition.

Changes in operating time of modern domestic EKG exсavators in dependence of their functioning conditions

Article preview

Domestically produced opencast excavators are shown to be serious competition for foreign hydraulic machinery. It is suggested to estimate the potential of an opencast excavator via its basic operation effectiveness factor equal to the ratio of the scoop payload to the nominal cost of excavator operations under its normal operational conditions. Comparing the theoretical values of standard operations of hydraulic excavators of the third type-and-size group during coal mining with domestically produced EKG-18R on their operation effectiveness factor shows that the excavator exceeds foreign hydraulic models from that group 2.7-3.3 times. Theoretical foundation is provided for a complex of factors that affect the operating time of single scoop open- cast excavators, a structure is offered for the model of comprehensive assessment of operating time for opencast excavators. Complex indicators are substantiated and proposed for supporting operational effectiveness of such excavators. Assessment is offered of operational effectiveness of EKG-18R excavators following the criterion of energy consumption per excavation of a unit of rock mass. Generalization analysis is given of a set of factors that affect the value of operating time for EKG-18R excavators. Proposals are put forward on upgrading the regulations for technical maintenance and repairs of EKG-18R excavators. The task of assessing the technical state of machinery calls for using integral criteria that would enable one to identify the current technical state and the residual resource of machine aggregates, their failure potentially resulting in emergency situations accompanied by considerable property damage. It is feasible to use an integrated indicator of the degree of degradation of s machinery item for such an integrated indicator, retrieved in the course of assessing the current technical state of that item during diagnostic procedures. In its turn, such and integral indicator of the state of an item is defined by the averaged value of diagnostic indicators reduced to their basic values with the account of  their individual weight factors.

Experimental evaluation of wear resistance of spur gears

Article preview

Extensive opportunities to influence the properties of involute gears are available with combined displacement of tooth profiles - a combination of radial and tangential displacements, including the use of cutting tools with a standard initial contour. In particular, by combined displacement, the bending strength and wear resistance of cylindrical gear teeth can be increased by one and a half to two times, which is commensurate with material replacement.

Energy service life of the plain bearing

Article preview

Design schemes of pneumatic, hydraulic and drilling machines with combined drive, used in mines and mines, mainly have mechanical drives of drilling rod rotation. This refers to machines of domestic and foreign production. A considerable part of failures of drilling equipment occurs exactly due to the fault of rotary units. One of the weak points of the design is often the transmission output shaft support unit made on the basis of plain bearing. The energy and life of such a sliding bearing is limited by the limit value of wear, leading to the occurrence of unacceptable misalignment of the gear wheels’ axes. The expression for determining the energy resource of the plain bearing from the condition of permissible volume wear of the liner material is proposed.
