Abstract
Spur gears with longitudinal tooth profile modification mesh creating which is suitable for stress analysis
Highlights
Spur gears are widely used parts in machines
New manufacturing technologies based on CNC machine tools allow manufacturing of spur gears with tooth profile modifications unavailable or hard to achieve with standard technologies
The goal of the work presented here was to develop a special computer program supporting the preparation of finite element meshes, necessary for numerical analysis of stresses in spur gears with longitudinal tooth profile modifications
Summary
The geometry of spur gear tooth profile is based on involute curve. Spur gears with longitudinal tooth profile modification mesh creating which is suitable for stress analysis circle. If listed parameters have defined values the geometry of the spur gear is fully described and the model of the gear may be prepared in any CAD program. Prepared discrete model of the gear may be imported into selected analysis software for example into ABAQUS [17] used by authors of this article. This method seems not to be effective when spur gear teeth faces are modified. The value of the modification can change on the height of the tooth of the spur gear
