Abstract

When calculating the stress-strain state of a cylindrical drum of a mine hoisting machine loaded with a metal rope, the stiffness parameters of the elastic lining and frontal surface are taken into account. It is defined that, depending on the values of the radial and bending stiffness of the frontal surface, two zones can be distinguished. If the parameters of the frontal surface fall into the first of them, the stresses in the shell slightly differ from the stresses in the hinged supported shell. The second zone is characterized by a sharp (up to 70%) increase in stresses. An algorithm has been developed for selecting rational parameters of a lined drum, which allows to reduce the stresses in the metal shell by up to 20%.

Highlights

An important role is played by improving the competitiveness of mining engineering products
In work [1], the structural and kinematic scheme of the diesel locomotive transmission is justified, and in work [2] a new conceptual approach is proposed for choosing the parameters of the transmission of wheeled vehicles
Mine hoisting installations are the main mode of transport connecting the underground workings of the mine with the day surface, the main part of which is the mine hoisting machine (MHM)

Summary

Introduction

An important role is played by improving the competitiveness of mining engineering products. [5] on its stress-strain state, to develop the method for calculating design loads [6], to create engineering methods for determining the parameters of rational structures of working bodies of mine hoisting machines , to increase the cable capacity of a single-drum mine hoisting installation [7], to substantiate the parameters of equipment for dewatering ropes of mine hoisting installations [8], to improve the method of calculating power factors in the turns of the multilayer winding of rubber cable [9], to determine the effect of rubber cable parameters on the torsional stiffness of the winding body [10]. That is why the justification of the algorithm for choosing the rational parameters of the elastic lining of the drums of mine hoisting machines is a topical scientific task
