The Parameterization Design and Motion Analysis for Multi-start ZA Worm Gearing Based on Virtual Processing

摘要

Archimedes worm gear’s teeth surfaces are comply and their models were usually built approximately in CAD. This article analyses the processing character and formation principle of the Multi-start ZA worm, builds the accurate model and makes the full parametric design. In environment of Pro/E, applying the entire relevance character between virtual assembly and component, simulating reality processes,the worm gear was produced virtually, and its model was built accurately. Furthermore, the generated worm gear and worm were assembled virtually and their motions were simulated and analysed.
