Abstract:
Conventional procedures are limited to contact pressure calculation of a solid gear. The objective of the article is to use advanced engineering tools for a numeric calculation of tooth contact pressure of thin-rimmed gears that have a special design and operating conditions. Presented finite element method approach uses a 3D parametric model of engaged gears to evaluate the influence of rotational speed on tooth contact pressure distribution. Application is shown on a thin-rimed gear with asymmetric web arrangement engaged with a solid spur gear. Contact pressure contour lines for various rotational speeds that can be used for recommendation of gear micro-geometry modifications and for defining parameters of gear life-cycle, are presented.
