Diseño de un engranaje hipoide y su fabricación en máquinas CNC multieje tecnica 4+1 ejes.

Abstract

A hypoid pinion was developed following the design methodology of the face-hobbing process proposed by the ISO 23509 standard, which due to its geometric characteristics such as unequal pressure angles and changes in tooth thickness along the pinion, generates a complex geometry. To obtain said geometry, a vertical machining center was used that has a fourth and fifth axis of movement, establishing that the use of specialized carving machines and tools is not required to obtain these geometries in low production batches. The Design Process Unlike most gear types that have closed-form equations that define their shape, the geometry of hypoid gears can only be calculated by solving equations governed by the manufacturing process, including machine settings. and cutter specifications. After the CAD design, the manufacturing process was planned, selecting standard material and tools for each of the material removal operations using the Nx CAM software, trajectories were verified in roughing and finishing processes of the pinion tooth profile to avoid collisions and damage to the part.
