IMPROVEMENT OF CONSTRUCTION OF DRAWINGS OF WORM GEAR GEARS IN AUTODESK INVENTOR PACKAGE

Abstract

The work is devoted to the description of an improved method for constructing worm gear drawings. The work shows that the Autodesk Inventor package design wizard allows you to create parametric 3D models of worm gear elements. But when building drawings of a 3D model of a worm gear, a number of conventions are not taken into account when depicting a worm gear, worm, and gear teeth in gear, as provided by the current standard.

The paper shows the advantages of an improved method that facilitates the construction of drawings of a worm gear in Autodesk Inventor, using parametric 3D models of assembly units “worm gear and worm in parametric shells”.

Assembly units were developed with the coincidence of variable identifiers when constructing 3D models “worm gear shell” and “worm shell” using reference data (basic geometric parameters of the worm gear and the worm) as initial parameters for the possibility of storage and use during parameterization.

When creating drawings for a worm gear, the assembly unit “worm gear” is used and an algorithm for representing the geometric information of its elements with arbitrary initial parameters is developed to facilitate the construction of drawings in Autodesk Inventor package in accordance with the current standard.

The proposed improved method for making drawings of worm gears with arbitrary output parameters in the Autodesk Inventor package can be used in production to optimize the development of design documentation in accordance with the current standard.

The parametric approach made it possible to expand the use of the parametric ZD model of worm gears, namely, the ability to create drawings of worm gears with arbitrary output parameters in accordance with current standards.
