Vrednotenje in primerjava Oldhamove in Schmidtove sklopke

Iljaš, Vid (author), Šeruga, Domen (mentor), Nagode, Marko (co-mentor)

Diplomsko delo obravnava vlogo sklopk in opis glavnih značilnosti Oldhamove in Schmidtove sklopke. Sledi izpeljava prenosa kotne hitrosti med vhodno in izhodno gredjo pri posamezni sklopki. Kotna hitrost je enaka na vhodni in izhodni gredi pri obeh sklopkah. Pri Schmidtovi sklopki je prikazana izpeljava za določitev sil, ki se pojavijo v povezovalnih elementih. Opredeljen je material in izvedeni so vsi izračuni, ki so potrebni pri konstruiranju vsake sklopke. Sledi trdnostna analiza z metodo končnih elementov, kjer se izkaže, da obe sklopki zdržita napetosti, ki jih vnesemo v material. Na koncu sklopki primerjamo. Zaradi enostavnosti sklopke se pri nizkih radialnih nepravilnostih bolj obnese Oldhamova sklopka.

• Title: Evaluation and comparison of Oldham and Schmidt coupling

Abstract

The thesis deals with the role of couplings and description of the main features of Oldham and Schmidt couplings. This was followed by derivation of the angular velocity transmission between the input and output shafts at each coupling. The angular velocity is the same at the input and output shafts in both coupling. In the respect of Schmidt coupling the derivation has shown to determine the forces in connecting elements. Material is defined and all calculations necessary for construction of each coupling are performed. The finite element method follows where both couplings withstand the stresses we put on them. At the end we compare both couplings. Due to simplicity Oldham coupling is better choice when dealing with low radial misalignment.
