Description

Двум  цилиндрическими поверхност ми 7 и 8, которые соедин ютс  между собой перемычкой 9. Устанавливаетс  кольцо 5 на кольцевом выступе 10, который предусмотрен на внутренней поверхности кольца 1, Внутренн   поверхность кольца I содержит далее по осевой окружности вторую внутреннюю ступеньку И, состо щую из осевой опорной поверхности 12, лежащей в той же плоскости , что и перемычка 9, а также из цилиндрической поверхности 13.
Поэтому после того, как промежуточное кольцо 5 устанавливаетс  между цилиндрическими поверхност ми 7 и 8, остаетс  кольцевое пространство, йрйгодное дл  установки запирающего кольца 14 дл  промежуточного кольца 5 .
Запирающее кольцо 14 имеет по своей нижней поверхности зубчатые выступы 15. Под воздействием дав щего усили  поверхность запирающего кольца 14 и его бокова  поверхность свариваютс  с плоской поверхностью 12 и с цилиндрической поверхностью 13 ступеньки 11, образу  с ней оДно целое. После проведени  такой сварки
745381
общий узел из трех колец 1, 5, 14 имеет окончательный вид.
