20.500.12556/RUL-186684 Razvoj in optimizacija jermenskega pogona za delovanje v agresivnem kemičnem okolju na galvanski liniji Development and optimization of a belt drive for an aggressive chemical environment on an electroplating line Pri procesu galvanizacije bakrenega traku transportni sistem obratuje v izjemno agresivnem kemičnem okolju zaradi prisotnosti močnih kislin, kar povzroča visoke stroške vzdrževanja in pogoste zastoje linije. Obstoječi jermenski pogon, ki skrbi za vodenje traku skozi procesne kadi, ne dosega pričakovane življenjske dobe, glavni vzrok pa je prezgodnja odpoved komponent zaradi prekomerne obrabe jermena, korozije jermenic in neustreznega statičnega napenjalca. V zaključni nalogi je najprej opravljena diagnostika poškodb obstoječega sistema, na podlagi katere je zasnovana nova rešitev. Osrednji del predstavlja razvoj in konstruiranje dinamičnega napenjalnega mehanizma v programskem okolju Creo Parametric, prilagojenega obstoječim prostorskim gabaritom in obratovalnim parametrom linije, vključno z opredelitvijo kinematike in potrebnih sil za zanesljiv tek jermena. Dodatno so preizkušeni materiali jermenov glede odpornosti na agresivno kemično okolje. Rešitev je preverjena z izdelavo fizičnega prototipa, njegovo namestitvijo na linijo in obratovalnim testiranjem, s čimer je potrjena ustreznost prenove pred širšo implementacijo na preostalih pogonskih sklopih galvanske linije. In the copper strip electroplating process, the transport system operates in an extremely aggressive chemical environment due to the presence of strong acids, causing high maintenance costs and frequent line downtime. The existing belt drive, which guides the strip through the process tanks, does not reach its expected service life, with premature component failure caused mainly by excessive belt wear, pulley corrosion, and an inadequate static tensioner. This thesis first diagnoses the damage of the existing system, on the basis of which a new solution is designed. The core part is the development and design of a dynamic tensioning mechanism in Creo Parametric, adapted to the existing spatial constraints and operating parameters of the line, including the determination of kinematics and the forces required for reliable belt operation. Belt materials are additionally tested for resistance to the aggressive chemical environment. The solution is verified through the manufacture of a physical prototype, its installation on the line, and operational testing, confirming the suitability of the redesign prior to wider implementation on the remaining drive units of the electroplating line. jermenski pogon galvanska linija agresivno kemično okolje napenjalni mehanizem obraba jermena konstruiranje belt drive electroplating line aggressive chemical environment tensioning mechanism belt wear design true false false [M.
