“…Prosiguiendo con el tema, el estudio adelantado por Hotait [32] proporciona un conjunto de datos experimentales del error de transmisión fundamentado en la relación entre el error estático y el error de transmisión dinámico en los dientes de un engranaje recto. De igual modo, se completa el estudio en términos de establecer la relación entre la durabilidad y la medida del ruido generado por el engranamiento de los dientes.…”

INTRODUCCIÓNEl diseño de perfiles especiales está enmarcado dentro de una de las áreas de exploración orientada al desarrollo de sistemas de transmisión para aplicaciones específicas en gran variedad de aplicaciones industriales, las cuales emplean perfiles con diferentes características geométricas. Si bien el cálculo del perfil especial para un diseño exacto requiere de gran cantidad de operaciones matemáticas y precisión en el proceso de manufactura, sorprende ver que con los avances tecnológicos logrados en máquinas herramientas para el mecanizado de perfiles, la industria cuenta, entre otros, con equipos CNC de gran versatilidad en su programación, lo cual facilita el mecanizado de perfiles de engranaje y piezas con un alto grado de complejidad.En este orden de ideas, en este trabajo se resalta una serie de investigaciones que sirve como marco de referencia para tener en cuenta en un diseño integral del engranaje y se describen los conceptos utilizados en los principales métodos de diseño para la generación del perfil. Por consiguiente es un tema de interés para el análisis y desarrollo de nuevos perfiles de engranajes, por lo cual su estudio requiere de muchas variables, limitaciones y relaciones que permitan lograr un perfil óptimo para una aplicación específica.

“…A gear dynamics test set-up with integrated root strain and dynamic transmission error measurement systems was described by M.A. Hotait [19], in which dynamic factor and dynamic transmission error measurements from both unmodified and modified spur gears were presented and the corresponding relationship was demonstrated experimentally. Tengjiao Lin [20] utilized the finite element modeling to obtain the machining and assembly errors of the gear system, which was applied to the kinetic model, and the dynamic transmission error was calculated.…”

For the nonlinear disturbance actual issues of the model space drive mechanism two-stage spur gear system, a nonlinear dynamic model of 14-DOF (degree of freedom) two-stage spur gear with time-varying stiffness and damping was established. This model has been developed previously by the authors to access the large inertia on the dynamic response of spur gear space driving mechanism, and its effectiveness was proved by a motion simulation experiment. In this paper, the profile error (PE) and the index error (IE) were enhanced in the dynamic model. The effects of profile error, index error, and variable load torque on transmission error (TE) were analyzed, while the optimization was proposed according to the analyzed result. The peak-to-peak value of the optimized load transmission error (LTE) was reduced by 60.7%, which improved the transmission accuracy and reduced the phenomenon of disturbance. The research of nonlinear dynamical model of two-stage spur gear and the TE of the large inertia load were enriched, which provided an important reference for the actual design of the gear system.

“…Strain measurements in the root fillet of gears along the face width direction have been used commonly in gears to study load distributions (Hotait and Kahraman, 2013) as a function of misalignments (Hotait and Kahraman, 2008) and index errors (Handschuh et al, 2014. This study proposes an experimental setup that allows accurate spline tooth root strain measurements with the goal of establishing an experimental database on load distributions of splined joints subject to static spur and helical gear loading conditions.…”

Splined joints are commonly used to transmit rotary motion from a shaft to machine elements such as gears. While computationally efficient spline load distribution models have recently been proposed, there is no validated load distribution model of a splined joint due to lack of high-fidelity experimental data. Accordingly, this study aims to establish an extensive experimental database on load distributions of splined joints subject to both spur and helical gear loading conditions. A quasi-static, spline-specific test setup is developed and instrumented. A test matrix covering various loading conditions is executed in order to form a spline load distribution database. The experimental data illustrates the cyclic nature of loads and resultant stresses on spline teeth caused by rotation of the spline teeth in relation to the gear mesh that loads the splined joint. A nonlinear relationship between torque applied and resultant stress is revealed, as well as the relationship between the location of maximum stress along the face width and the amount of lead crown modification applied. Lastly, simulation results from the model of Hong et al. (2014b) are compared to the experimental data under spur and helical gear loading conditions to assess the premise of such models.
