Unformatted text preview: using different concepts. We principally need a detailed description of each variation to characterize the geometrical behavior [Ballot et al.,1997], [Dantan et al.,2005].The approach used in this paper is the parameterization of deviations (section 2.1) and the Tooth Contact Analysis (TCA) for geometrical behavior model (section 2.3). The principle idea of TCA is based on simulation of tangency of tooth surfaces being in mesh. The TCA program provides the information about the function of transmission errors [Litvin, 2004]. 2.1. Geometrical description of variations of bevel gears Usually, geometrical behavior description needs to be aware of the surface deviations of each part (situation deviations and intrinsic deviations) and relative displacements between parts according to gap (gaps and functional characteristics). Compared with the nominal model, each substitute surface has position variations, orientation variations and intrinsic variations [Ballot et al.,1997], [Dantan et al.,2005]. In the case of gears, the geometrical behaviour description principally needs an exact analytical definition of tooth surface....
