Abstract

Изобретение относитс к машиностроению, а именно к зубчатым передачам. Цель изобретени - повышение надежности и долговечности упругого зубчатого колеса. Это достигаетс равномерным распределением нагрузки на силовые элементы зубчатого колеса. Венец 3 с внутренними шлицами 4 установлен на дисках 1,2. Ступица выполнена из двух разъемно соединенных симметричных относительно третьего диска 5 частей 7 и 8. Дл упругой передачи нагрузки со ступицы на венец 3 служат упругие элементы 12 и диск 5 с наружными шлицами 6 дл взаимодействи со шлицами 4 венца 3. Благодар равномерному распределению шлицев 6 и 4 по окружности колеса исключаютс местные деформации венца 3 от окружных усилий, в то врем как развитые опорные поверхности дисков 1,2 воспринимают действие на венец 3 радиальных усилий. 2 ил.This invention relates to mechanical engineering, namely gearing. The purpose of the invention is to increase the reliability and durability of the elastic gear. This is achieved by uniformly distributing the load on the power components of the gear. The crown 3 with internal splines 4 is mounted on disks 1,2. The hub is made of two detachably connected 5 parts 7 and 8 symmetrical with respect to the third disk. For elastic transfer of load from the hub to the crown 3, elastic elements 12 and disk 5 with external splines 6 are used to interact with splines 4 of the crown 3. Thanks to the uniform distribution of the splines 6 and 4 circumferentially, local deformations of the rim 3 from circumferential forces are eliminated, while the developed bearing surfaces of the disks 1,2 perceive the effect on the rim 3 of radial forces. 2 Il.
