Analysis and Design of the Pinion Machine Settings for Spiral Bevel Gears

摘要

In some cases, some of the pinion machine settings' values calculated by local synthesis method may be too large for machine-tool and beyond the adjustive ranges. A new approach 1 for design of spiral bevel gears based on local synthesis method is proposed. One of pinion machine settings, work offset, can be assigned in advance, and this gives more freedom for designing pinion tooth surface. In order to get a predesigned parabolic function of transmission errors with limited magnitude of maximal transmission errors, the contact path with the shape of straight line, genetic algorithm is used. In this process, tooth contact analysis (TCA) is embedded to constitute the design route, so that the overall control of engagement quality is realized.
