MODELING OF SPUR GEAR MESH STIFFNESS AND STATIC TRANSMISSION ERROR

A modified transmission error (TE) model is introduced for analysing t he effects on the transmission error of variation of tooth body stiffn ess with load application point, and a simulation program for transmis sion error computation with varying stiffness has been developed. In o rder to obtain the case where the tooth deflection component is the do minant source of the TE, nylon gears were used in this study. All the simulation results have been compared with the measured transmission e rrors from a single-stage gearbox. Even through carried out on low pre cision gears, the validity of the model for the more flexible nylon ge ars indicates that the mode can be used for anlysing the transmission error of high-precision gear sets.
