20.500.12556/RUL-163977 Analysis of power losses and experimental method for determining resistance in electric elevators Analiza izgub moči in eksperimentalna metoda za določanje upora pri električnih dvigalih To be able to carry out a high-quality analysis of the operation and design of elevator systems with a driving pulley, it is necessary to determine the size of the losses that occur in the drive mechanism and elevator guide rails. The paper defines an experimental procedure for determining the losses and the efficiency coefficient of elevator facilities depending on the relative load of the cabin in operational conditions. The experiment was carried out on a passenger elevator with a rated load of 320 kg and a lifting height of 28 m. An analysis of the resistance, i.e., the source of power losses in vertical lifting devices, was performed, the most significant of which occur and are especially pronounced in worm gear reducers and on the guiding system of the cabin and counterweight, where the type of guiding elements also has an influence. A particular problem is expressed due to the changing state of the contact surfaces (between the guide rails and the guide shoes) during exploitation and the eccentric loading of the cabin. Also, the paper analysed the obtained measurement results to determine the dependence of the efficiency coefficient of the facility concerning the relative load of the cabin. electric elevators guide rails resistances driving mechanism resistances efficiency determination električna dvigala upor vodilnih tirnic upor pogonskega mehanizma določitev izkoristka true false true Angleški jezik Slovenski jezik Članek v reviji 2024-10-15 10:35:52 2024-10-15 10:35:56 2025-02-06 08:11:38 0000-00-00 00:00:00 2024 0 0 Str. 466-482 no. 9/10 Vol. 70 Sept.-Oct. 2024 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 621.8 0039-2480 10.5545/sv-jme.2024.1006 211557379 Analysis_of_Power_Losses_and_Experimental_Method_....pdf Analysis_of_Power_Losses_and_Experimental_Method_....pdf 1 9EC90D1AD922E885830E394D879C7EDB bc26a422bbc8322f902c0a6076855d41d1b027f1af20cc8a53e51580c33e80d5 67efb568-8ad0-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=194009 https://www.sv-jme.eu/sl/article/analysis-of-power-losses-and-experimental-method-for-determining-resistance-in-electric-elevators/ 1 4556cba9-8ad0-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=194008 Fakulteta za strojništvo Strojniški vestnik 0 0 0
