Method for removing material of cavity between teeth of cylindrical arched gear wheel

FIELD: mechanical engineering. SUBSTANCE: invention relates to a method for manufacturing cylindrical arched gear wheels with circular teeth having an involute transverse profile. The method of removing the material of the space between the teeth of a cylindrical arched gear wheel includes cutting out an annular groove in the tooth space and removing the material from Zone Z 1 between the concave side surface of Tooth 1 and the side surface of the annular groove closest to it, as well as removing the material from Zone Z 2 between the other side surface of the annular groove and the convex side surface of adjacent Tooth 2. Material removal from both Zone Z 1 and Zone Z 2 is carried out by means of generating. As a result of performing each of the generating in Zone Z 1 , a surface is formed that is equidistant to the concave lateral surface of Tooth 1, and in Zone Z 2 - a surface equidistant to the convex lateral surface of Tooth 2. Generating is performed using a cutter head. An annular groove in the tooth space is cut out by at least one annular drilling. Cutting in the hollow of the annular groove is carried out using a tool head or a crown drill. EFFECT: unhindered exit of chippings from the cutting zone is provided and the load on the main drive of the machine and the cutting head is reduced. 20 cl, 9 dwg РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) (13) 2 749 955 C1 (51) МПК B23F 9/00 (2006.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ (12) ОПИСАНИЕ ИЗОБРЕТЕНИЯ К ПАТЕНТУ (52) СПК B23F 9/00 (2020.08) (21)(22) Заявка: 2019143795, 23.12.2019 (24) Дата начала отсчета срока действия патента: (73) Патентообладатель(и): Общество с ограниченной ответственностью "Техно Инжиниринг" (RU) Дата регистрации: 21.06.2021 (45) Опубликовано: 21.06.2021 Бюл. № 18 2 7 4 9 9 5 5 R U (54) СПОСОБ УДАЛЕНИЯ МАТЕРИАЛА ВПАДИНЫ МЕЖДУ ЗУБЬЯМИ ЦИЛИНДРИЧЕСКОГО АРОЧНОГО ЗУБЧАТОГО КОЛЕСА (57) Реферат: Изобретение относится к способу выполняют посредством обкатов.
