Summary. In this article, one of the most promising methods of increasing the operational characteristics of a vehicle gear by the use of cylindrical gear drives with arched teeth is presented. Despite a number of advantages, these gearings are not widely used due to design and manufacture complexity. Possible options of edge cutting machining of cylindrical gearwheel arched teeth are considered. The progressive process technology proposed by the authors combines the roughing by multi-purpose cutter head for bevel gear with circular tooth and finishing by cutter head with zero angle of cutting edge. ВОЗМОЖНОСТИ ПОВЫШЕНИЯ ЭКСПЛУАТАЦИОННЫХ ХАРАКТЕРИСТИК ПРИВОДОВ ТРАНСПОРТНЫХ СРЕДСТВ ЗА СЧЕТ ПРИМЕНЕНИЯ АРОЧНЫХ ЦИЛИНДРИЧЕСКИХ ЗУБЧАТЫХ ПЕРЕДАЧАннотация. В статье представлен один из перспективных способов повышения эксплуатационных характеристик приводов транспортных средств за счет применения цилиндрических передач с арочными зубьями. Несмотря на целый ряд преимуществ, такие передачи не имеют широкого распространения это связано со сложностью их проектирования и изготовления. Рассмотрены возможные варианты лезвийной обработки арочных зубьев цилиндрических колес. Авторами предложен прогрессивный технологический процесс. Сочетающий черновую обработку универсальными резцовыми головками для обработки конических колес с круговым зубом и чистовую -резцовыми головками с нулевым углом профиля.

In gear transmissions there is a great wear, because there is a sliding velocity between tooth. This sliding in spite of be inevitable has great repercussion over Tooth wear. In gears of sugar mill rollers distance between centers changes during operation and wear is bigger. For this purpose full involute gears are used and sliding increases. Expressions for calculating sliding velocities in such gears are shown in this article. Keywords:Transmitters of Engrenagens, sugar cane, Application to the crowns.Influencia de la variación de la distancia entre centros en la velocidad de deslizamiento de las transmisiones por engranajes. Aplicación a las coronas de molinos de caña de azucar RESUMEN En las transmisiones por engranajes de perfil evolvente se produce un alto deslizamiento entre los dientes, ya que existe una componente de la velocidad a lo largo del diente. Este deslizamiento a pesar de ser inevitable, tiene repercusiones considerables en el desgaste del perfil. Existen numerosas aplicaciones industriales donde las transmisiones por engranajes trabajan con variación de la distancia entre centras de operación, tales como los molinos de caña de azúcar, trenes de laminado, etc. En estos casos se usan engranajes de evolvente alargada, siendo aun mayor el deslizamiento de un perfil sobre el otro, al existir una nueva componente de la velocidad producto del movimiento de aproximación y separación de las ruedas dentadas de acuerdo a la abertura del molino. En el trabajo se hace un análisis de las expresiones para el cálculo de las velocidades de deslizamiento de este tipo de transmisiones; las cuales no aparecen en la literatura tradicional de transmisiones por engranajes. Se muestran programas de computación para el cálculo de estas velocidades. Palavras-Chave:Transmisiones por engranajes, caña de azucar, Aplicación a las coronas de molinos. I. INTRODUCCÍONEl desgaste es una de las fallas fundamentales de las transmisiones por engranajes que trabajan con condiciones deficientes de lubricación [1][2]. Esta situación se ve agravada aun más si los engranajes trabajan además con variación de la distancia entre centros durante la explotación. Tal es el caso de las coronas de molinos de caña de azúcar, donde esta es una de las principales causas de deterioro. En Cuba se utiliza una amplia gama de coronas de molinos con diferentes parámetros geométricoa (número de dientes, módulo, etc.). Estos perfiles se designan por letras que van desde la A hasta la P en orden decendente de tamaño.En los engranajes de evolvente que trabajan con distancia entre centros constante este fenómeno ha sido estudiado profundamente por numerosos autores, no obstante en engranajes de perfil especial que trabajan con una variación continua de la distancia entre centros no ha sido estudiado a profundidad, ya que estos casos solamente se presentan en aplicaciones muy específicas.El desgaste de una transmisión dentada depende de muchos factores, pero no cabe lugar a dudas de que el deslizamiento juega

“…The tooth wear changes its profile, and frequently increases gear vibration and noise. INOUE, et al [10][11][12][13] , studied the wear depth on the tooth surface with the contact stress, the sliding velocity, the oil film thickness based on the wear theory deduced by Soda under the lubricated condition, and investigated the relation of these factors with the noise and vibration of gears. CAO, et al [14][15] , investigated the correlation between gear wear and vibration analysis.…”

Straight bevel gears are widely applied in automotive, aerospace, chemical and many other fields as one of the most common type of gears. Currently, the researches on straight bevel gears have focused on the fields of fatigue, wear, noise and vibration, while little attention is paid to the effect of multiple alignment errors on the gear tooth wear. To study the influence of alignment errors on the gear tooth wear, a simulated model of a straight bevel gear pair is established. Then, the contact pressure on the tooth surface is analyzed under the various alignment errors according to the Archard wear relationship. The main combinations of alignment errors played vital roles on the tooth wear are investigated. The result shows that under the single alignment error, the contact pressure moves to the tooth heel and increases greatly at here when P=0.1 or G=0.1; when E=-0.03, the contact pressure greatly increases at the tooth heel, but it obviously increases at the tooth toe when E=0.03; the alignment error γ=1 has little effect on the contact pressure on the tooth surface. Moreover, the combination of P, G, E<0 and γ is the most dangerous type among the multiple alignment errors. This research provides valuable guidelines for predicting the tooth wear under various alignment errors.
