Mingxin Li: Three Dimensional Solid Modeling of Gear Based on Solidworks Secondary ..

We study three dimensional parametric agile design of gears and related software platforms in terms of: parameterization, modularization, and the software being easy to use, expand and maintain. We base our study on SolidWorks platform, aiming to generate 3-D solid models of gears automatically in terms of: i) inputting parameters to improve the modeling speed, ii) build up foundations for structure design, iii) do dynamic simulation, and iv) interference checks and v) use finite element analysis to improve design efficiency. Our results include: i) 3-D accurate description for involute gear is realized, ii) accurate specification of involute gear in SolidWorks has been achieved, iii) parameterized agile modeling system modules of involute cylindrical spur gear, helical gear and internal gear have been developed using SolidWorks as support platform, and iv) success in adopting object oriented technology for involute coordinate equations.
