В статье рассмотрено повышение нагрузочной способности цилиндрического эвольвентного зацепления с арочными зубьями за счет оптимизации геометро-кинематических и прочностных характеристик. Поставленная цель достигается за счет того, что вдоль ширины венца колеса арочная часть зуба, расположенная в средней части ширины венца, сопряжена с косозубыми полушевронами, что увеличивает толщину и прочность зубьев на торцах и снижает концентрацию контактных напряжений и виброактивность зацепления под действием внешней нагрузки.
It was considered in this article the increasing of the loading ability of the cylindrical involute hooking with the arched points due to the optimization of the geometrical-kinematic characteristics. The assigned aim is achieved due to the fact that along the width of the wheel's crown the arched part of the tooth, locating in the middle of the wheel's crown, attends with helical-half chevrons, that allow to increase the axial contact ratio of the gear drive and the teeth thickness on butt ends towards the action of the distributed contact load. In that connection, that wheels cut with the involute end mill, the shape's and sizes' optimization of the heel pattern achieve due to modification arched teeth, that decrease contact's stress concentration and vibroactivity gearing under the influence of the external load, that essentially influence on the increase transmission's resources. The authenticity has been confirmed by theoretical studies on the technology and the experimental phase of the research project.
