A modular approach to computing spiral bevel gears and curvic couplings

摘要

In general, bevel gears and curvic couplings are completely different elements. Bevel gears rotate on nonintersecting axes with a ratio based on the number of teeth. Curvic couplings work like a clutch (Fig. 1). Computing these different elements in the same manner is based on the idea that cuivic couplings are actually a special kind of plunge-cut spiral bevel ring gear with a pitch angle of 90°, a spiral angle close to 0° and a constant tooth depth. This principle allows curvic couplings to be computed like spiral bevel gears.
