Возможности использования AutoCAD при проектировании новых профилей зацепления

Abstract

Modern engineering places high demands on machine parts (increase of loading capacity and resource, low the weight, reducing design time), which are often contradictory. Therefore, the task of finding the optimal parameters of the items is very difficult. All this fully applies to the gears. Promising is mesh with the convex-concave tooth contact. This type of mesh is described by complex functional dependencies. The existing top-level software (CATIA, Pro/ENGINEER, ANSYS) allow for a full cycle of synthesis and analysis of gears. However, the products of the lower level (AutoCAD) with extension programming language AutoLISP allow synthesis of tooth profile and conduct geometric analysis. The article describes the implementation of a geometric synthesis and analysis of gears with convex-concave tooth contact in AutoCAD system with the AutoLISP extension. This software implementation can create gears in 2D and 3D, edit the synthesized profile and output control sizes of gears.
