Over the last 15 years, there has been
significant growth in the number of
transmission types as well as their complexity: manual, conventional automatic, dual clutch, automated manual, continuously variable, split power and pure EV transmissions.
A transverse-torsional dynamic model of a spur gear pair is employed to investigate the
influence of gear tooth indexing errors on the dynamic response. With measured long-period
quasi-static transmission error time traces as the primary excitation, the model predicts
frequency-domain dynamic mesh force and dynamic transmission error spectra. The dynamic
responses due to both deterministic and random tooth indexing errors are predicted.
Since we began publishing in 1984, Gear Technology's mission has been to educate our readers. For 31 years, we've shown you the basics of gear manufacturing as well as the cutting edge. We take our educational mission quite seriously, and we go through steps that most publishers don't have time for or wouldn't consider.
Developed here is a new method to automatically find the optimal topological modification from the predetermined measurement grid points for bevel gears. Employing this method
enables the duplication of any flank form of a bevel gear given by the measurement points and the creation of a 3-D model for CAM machining in a very short time. This method not only
allows the user to model existing flank forms into 3-D models, but also can be applied for various other purposes, such as compensating for hardening distortions and manufacturing deviations which are very important issues but not yet solved in the practical milling process.
