Experimental identification of the impact of sectional satellite wheels on the load distribution in the meshing of the planetary gear in mining machines

Filipowicz Krzysztof, Kuczaj Mariusz, Baranowski Sławomir

New Trends in Production Engineering

This article attempts to solve the problem of load compensation in mesh planetary gearing, with the innovative design idea, resulting from the increased plasticity of the planet wheels (satellite). The cognitive main objective of the experimental work was carried out to identify the comparative effect of the split narrow planet gears, on the load distribution on the length of the teeth of the planet gears of the central wheel of the planetary gear. Achieving this aim, in addition to in-depth analysis, requires experimental research on a specially-built test stand and simulation tests on a solid model of the transmission using the finite element method (FEA). This article presents the concept of a novel test stand, design methodology and research on the influence of the sectional satellite wheels on the load mesh of planetary gears in mining machines.

Stanowisko badawcze do wyznaczania wpływu dzielonych kół satelitów na obciążenie w zazębieniach przekładni planetarnych

W artykule podjęto próbę rozwiązania problemu wyrównywania obciążeń w zazębieniach przekładni planetarnych, przez zastosowanie innowacyjnego pomysłu konstrukcyjnego, polegającego na zwiększeniu podatności kół obiegowych (satelitarnych). Przedstawiono również koncepcję nowatorskiego stanowiska badawczego oraz metodykę badań wpływu dzielonych kół satelitarnych na przebieg obciążenia w zazębieniach przekładni planetarnych maszyn roboczych.

The article presents the experimental and theoretical research of reinforced concrete beams deformations, damaged in the conditions of simultaneous influence of aggressive environment and loading with their further renewal. The peculiarity of this research is that during influence of aggressive environment reinforced-concrete beams were tested both under the action of loading and without it. The influence of aggressive environment and renewal took place in the conditions of the operating loading on the reinforced-concrete beams. Such a combination of influences allows to define the optimal method of research of the renewal process in reinforced-concrete structures and the influence of loading, at which the strengthening takes place on the efficiency of renewal and deformations of experimental samples. The experimental and theoretical values of deformations of reinforced-concrete beams which were renewed without loading and under the operating loading are obtained. Their comparison is carried out with the purpose of determining the optimal method of research of such structures.
