Zusammenfassung:The invention relates to the machining of teeth of the precession gearwheels, namely to the shaving of teeth.The process for shaving the teeth of the precession gearwheels includes shaving of teeth of the gearwheel (4) with a satellite tool (1), which simulates a real transmission and includes two gear rings (2, 3) with drive (8) and machining (6) rollers, on the surface of the latter are made chip removal channels. The rollers (6, 8) are made in the form of a truncated cone with the apex towards the gear rings (2, 3) of the satellite tool (1). The satellite tool (1) is communicated a precession motion with an axial advance with its rotation consecutively in both directions, then the satellite tool (1) performs a free running consecutively in both directions. The chip removal channels of the machining rollers (6) are made in the form of a spiral with winding directions opposite of the previous roller. Invenţia se referă la prelucrarea dinţilor roţilor dinţate precesionale, şi anume la şeveruirea dinţilor.Procedeul de şeveruire a dinţilor roţilor dinţate precesionale include şeveruirea dinţilor roţii dinţate (4) cu ajutorul unei scule-satelit (1), care imită o transmisie reală şi include două coroane (2, 3) cu role de antrenare (8) şi de prelucrare (6), pe suprafaţa ultimelor sunt executate canale de evacuare a aşchiilor. Rolele (6, 8) sunt executate în formă de trunchi de con cu vârful spre coroanele (2, 3) sculei-satelit (1). Sculei-satelit (1) i se comunică o mişcare de precesie cu un avans axial cu rotirea ei consecutiv în ambele direcţii, după care scula-satelit (1) efectuează o rulare liberă consecutiv în ambele direcţii. Canalele de evacuare a aşchiilor ale rolelor de prelucrare (6) sunt executate în formă de spirală cu direcţii de înfăşurare opuse faţă de rola precedentă. Изобретение относится к обработке зубьев прецессионных зубчатых колес, а именно к шевингованию зубьев.Способ шевингования зубьев прецессионных зубчатых колес включает шевингование зубьев зубчатого колеса (4) с помощью инструмента-сателлита (1), который имитирует реальную передачу и включает два венца (2, 3) с приводными (8) и обрабатывающими (6) роликами, на поверхности последних выполнены каналы для отвода стружки. Ролики (6, 8) выполнены в виде усеченного конуса с вершиной к венцам (2, 3) инструмента-сателлита (1). Инструменту-сателлиту (1) сообщают прецессионное движение с осевой подачей с его вращением последовательно в обе стороны, после чего инструмент-сателлит (1) выполняет
