Integration of numerical analysis, virtual simulation and finite element analysis for the optimum design of worm gearing

Abstract

Due to the complicated tooth geometry of worm gears, their design to achieve high capacity and favourable performance is a tedious task, and the optimum design is hardly to obtain. In order to overcome this problem, the authors developed an integrated approach which consists of three modules: numerical analysis, three-dimensional simulation and finite element analysis. It provides a powerful tool for optimum design of worm gears and is a general approach applicable for various types of worm gears. As case studies, two designs using the approach have been conducted, one for cylindrical involute worm gearing and the other for double enveloping worm gearing.

Design, Analysis And Experimental Study Of Worm And Worm Gear Pair For Plug Valve Application

“…We have chosen 10C4, 14C4 (Case Hardened steel) for worm gear which has ultimate tensile stress 980 N/mm 2…”

A holistic product design and analysis model and its application in railway vehicle systems design

“…The CAD models can be imported via common exchange file formats such as STEP, 14 Initial Graphics Exchange Standard (IGES) 15 and STL (Stereolithography CAD file format). 16 These intermediate CAD file formats can be adopted by most of the commercial CAD and CAE systems.…”

New Way for the Innovation of Gear Types

“…Most modern programs apply the TCA (Tooth Contact Analysis) method for optimizing contacting properties (Su & Qin, 2003;Litvin & Fuentes, 2004). One of the best realizations uses real time ease-off topography manipulation through surface or kinematical system parameter modification using mouse and visual feedback (Stadtfeld, 1999).…”
