    Vplyv striedavého namáhania na zmenu teploty vzduchu v pružnom pneumatickom elemente
    (University of Žilina, 2024) Krajňák, Jozef; Maláková, Silvia; Kepeň Harachová, Daniela
    Rubber as a material is one of the frequently used materials in mechanical engineering. This article deals with rubber, or flexible pneumatic elements, the main part of which is rubber. We determine the effect of alternating stress on the temperature change in the flexible pneumatic element under this variable load. We describe a device that serves this purpose. This device was designed and manufactured in our department. We also determine the effect of the air pressure of the flexible element on the temperature of the air and the temperature of the flexible elements. We need to find out the magnitude of these temperatures so that we can determine whether these flexible elements can work without significant negative changes in physical properties.

    Konštrukcia pružného kolesa harmonického prevodu
    (University of Žilina, 2024) Kepeň Harachová, Daniela; Krajňák, Jozef; Maláková, Silvia
    Flexspline is one of the most important components of harmonic drive. Flexspline is very adversely stressed during operation. In essence, stresses from deformation by the generator, stresses from the transmitted load and local stresses from the bending of the teeth in the tooth gaps act in it. Flexspline is radially flexible, but torsionally very stiff. When the wave generator is inserted into the Flexspline, the gear takes on its elliptical shape. When designing a flexible wheel, it is very important to determine and correctly choose its geometric properties.

    Vplyv tvaru telesa na deformáciu čelného ozubenia
    (University of Žilina, 2024) Maláková, Silvia; Kepeň Harachová, Daniela; Krajňák, Jozef
    The article is devoted to the analysis of the influence of the basic parameters of the body of the spur gear on the deformation of the teeth in meshing. The problem is solved for spur gears of large dimensions, the semi finished product of which can be a weldment, casting or forging. Gear deformations are determined by the finite element method. Examples of simulation and subsequent processing of the results demonstrate the extent of the influence of individual parameters of the gear body on the deformation of the gearing. At the same time, the results point to suitable designs of shape and dimensions to achieve the desired deformation of the teeth but with the smallest possible weight of the gears.
