Computer-assisted synthesis of wrapping cam mechanisms

Iskandar, Kurnia Dias 18 September 2008 (has links)
A wrapping cam mechanism consists of a cam wrapped by a belt or flexible band. An analytical method for synthesizing wrapping cam mechanisms has recently been developed. This thesis extends the previous work and describes the development of an interactive wrapping cam synthesis package based on analytical methods. The software presented in this thesis generates cam profiles for eight configurations of wrapping cam-pulley or wrapping cam-sprocket mechanisms. This software package has a graphical user interface to give intuitive interactions. The modularity of the software package increases the flexibility for future program extension. This thesis also discusses the extended synthesis methods for a wrapping cam-link mechanism. / Master of Science

Ein Beitrag zur kennwertorientierten Entwicklung kurvengesteuerter, ebener Schrittgetriebe

Heine, Andreas 18 September 2015 (has links)
Die vorliegende Arbeit befasst sich mit der kennwertorientieren Ermittlung günstiger Hauptabmessungen bei ebenen Schrittgetrieben. Auf Basis normierter Größen wird ein Verfahren vorgestellt, welches die Dimensionierung der Eingriffsorgane (Kurvenrollen) in den Syntheseprozess integriert und somit eine eigenschaftsbezogene Auslegung ermöglicht. Es werden Grenzabmessungen definiert und getriebespezifische, normierte Kennwert-Diagramme entwickelt, die dem Auslegungsprozess als Grundlage dienen. / The document covers the determination of convenient dimensions for indexing parallel cam mechanisms based on characteristic values. Based on this normalized values a method is introduced, which integrates the dimensioning of the cam rollers into the mechanism synthesis, hence a design process is facilitated regarding properties. Limitations for dimensions are defined and mechanism specific, normalized graphs will be the basis for the whole design process.
