Meshing Characteristics of the Oerlikon-Type Spiral Bevel Gears (In Case of the Driven Gear)

Abstract

The authors have conducted studies on the Oerlikon-type spiral bevel gears for several years. However, these studies are mainly about characteristics of drive gears, and those of driven gears are not yet clarified. In the case of spiral bevel gears, a pair of teeth of drive and driven gears mesh on a concavo surface and a convex one and consequently, it is the detenmined that meshing characteristics of driven gears differ from those of drive gears. In this paper, the authors examined stresses at the tooth root of the driven gears under various running conditions and compared the results with those in the case of drive gears. From this study, it was found that the experimental results of stresses at the tooth root of the driven gears agree with the computed results obtained by means of the W.Coleman equation, and that application of this equation for compution of tooth root stresses of the driven gear is effective.
