Description

Изобретение относитс к области обработки металлов давлением и может быть использовано в конструкци х привода прокатных станов.This invention relates to the field of metal forming and can be used in rolling mill drive designs.
Известен универсальный шарнир скольжени преимущественно привода прокатного стана, содержащий лопасть , ВИЛКУ и размещенные между ними вкладыши с соединительным пальцем Ci The universal sliding joint of a rolling mill drive mainly is known, which contains a blade, a FORK and inserts between them with a connecting pin Ci.
Недостатком такого шарнира вл етс быстрый и неравномерный износ бронзовых вкладышей ввиду значительной жесткости лопатки муфты давление между вкладышем и лопастью распредел етс по треугольнику, увеличива сь от центра к кра м вкладыша . Увеличенный износ на краю вкладыша приводит, к образованию больших зазоров и по влению динамических нагрузок. Ввиду по влени пиковых нагрузок, на краю вкладыша ограничиваетс нагрузочна способность шарнира . Срок службы вкладыша уменьшаетс , так как интенсивно изнашиваютс концевые его участки.The disadvantage of such a hinge is the rapid and uneven wear of the bronze liners, due to the considerable rigidity of the clutch blade, the pressure between the liner and the blade is distributed along the triangle, increasing from the center to the edges of the liner. Increased wear at the edge of the liner leads to the formation of large gaps and the appearance of dynamic loads. Due to the occurrence of peak loads, the load capacity of the hinge is limited at the edge of the liner. The service life of the liner is reduced, as its end sections wear out intensively.
Цель изобретени - выравнивание контактного давлени по ширине попасти и увеличение долговечности .вкладышей.The purpose of the invention is to equalize the contact pressure across the width of the pocket and increase the durability of the inserts.
Это достигаетс тем, что лопасть .выполнена с глухими поперечными ПОЛОСТЯМИ, выход щими на ее боковые поверхности.This is achieved by the fact that the blade is made with deaf transverse CAVITIES extending onto its side surfaces.
На фиг.1 показан шарнир, общий вид; на фиг. 2 - разрез А-А на фиг.1; на фиг. 3 - муфта шарнира; на фиг. 4 - схема распределени давлени между вкладышем и лопастью.Figure 1 shows the hinge, a general view; in fig. 2 shows a section A-A in FIG. in fig. 3 - hinge coupling; in fig. 4 is a diagram of the pressure distribution between the liner and the blade.

Лопасть муфты 1 снабжена полост ми 2, которые разъедин ют зону лопасти 3, контактирующую с вкладышем 4, 01 остова лопасти. Контактирук да The blade of the coupling 1 is provided with cavities 2, which separate the zone of the blade 3 in contact with the liner 4, 01 of the blade core. Contact person yes
5 пластина лопасти ввиду небольшой ее ТОЛЩИНЫ имеет возможность упруго деформироватьс , создава тем самым благопри тные услови дл более равномерного распределени контактного5, the blade plate due to its small THICKNESS has the ability to elastically deform, thereby creating favorable conditions for a more uniform distribution of the contact
