Spiral Bevel Gears

Abstract

Spiral bevel gears have found broad application in helicopter and truck transmissions and reducers for transformation of rotation and torque between intersected axes. Design and stress analysis of such gear drives has been a topic of research by many scientists including the authors of this book [Krenzer, 1981; Handschuh & Litvin, 1991; Stadtfeld, 1993, 1995; Zhang et al., 1995; Gosselin et al., 1996; Litvin et al., 1998a, 2002a; Argyris et al., 2002; Fuentes et al., 2002]. Reduction of noise and stabilization of bearing contact of misaligned spiral bevel gear drives are still very challenging topics of research although manufacturing companies [Gleason Works (USA), Klingelnberg–Oerlikon (Germany–Switzerland)] have developed skilled methods and outstanding equipment for manufacture of such gear drives.
