Description

Изобретение относитс  к области машиностроени  и может быть использовано в приводах с высокими скорост ми вращени  при наличии ударных нагрузок и значительных углах перекоса соедин емых валов . По основному авт. св. № 217153 известен универсальный шарнир, содержащий две вилки, соединенные между собой с помощью крестовины,снабженной втулками, выполненными из слоистых резинометаллических элементов, установленными на цапфах крестовины в проушинах вилок. Недостаток такой конструкции универсального шарнира заключаетс  в том, что, поскольку втулки имеют малую осевую жесткость , при радиальной несоосности соедин емых валов происходит смещение вилок в направлении осей указанных втулок. Это приводит к по влению в шарнире радиальных вибраций, разрушению втулок, что снижает срок службы шарнира и его нагрузочную способность. Целью изобретени   вл етс увеличение нагрузочной способности и QpoKa службы шарнира путем устранени  радиальных зазоров . Эта цель достигаетс  тем, что предлагаемый щарнир снабжен плоскими шайбами , выполненными из слоистых резиндметаллических элементов, установленными на торцах цапф крестовинь и зафиксированными в осевом направлении. На фиг. 1 изображен предлагаемый универсальный шарнир, общий вид; на фиг. 2 - сечение А-А на фиг. 1; на фиг. 3 - частичное сечение Б-Б на фиг. 1. Универсальный шарнир состоит из вилок 1 и 2, насаженных на соедин емые валы 3 и 4 и соединенных между собой крестовиной 5, цапфы которой вход т в проушины вилок. На цилиндрические поверхности цапф крестовины 5 установлены втулки 6, а на торцы - плоские щайбы 7, причем и те, и другие выполнены из слоистых резинометаллических элементов. В проушинах вилок 1 и 2 установлены стаканы 8, закрепленные винтами 9. Плоские шайбы 7 на торцах цапф крестовины зафиксированы от осевого смещени  с помощью крышек 10,The invention relates to the field of engineering and can be used in drives with high rotational speeds in the presence of shock loads and significant skew angles of the connected shafts. According to the main author. St. No. 217153 is known a universal joint, which contains two forks interconnected by means of a cross, fitted with bushings made of laminated rubber-metal elements, mounted on the cross of the cross in the eyes of the forks. The disadvantage of this design of the universal joint is that, since the bushings have low axial stiffness, when the shafts are radially misaligned, the forks move in the direction of the axes of the said bushings. This leads to the appearance of radial vibrations in the joint, the destruction of the sleeves, which reduces the service life of the joint and its load capacity. The aim of the invention is to increase the load capacity and QpoKa service of the hinge by eliminating radial clearances. This goal is achieved by the fact that the proposed joint is provided with flat washers made of laminated resindmetallic elements mounted on the ends of the crosses of the crosses and fixed in the axial direction. FIG. 1 shows the proposed universal joint, a general view; in fig. 2 is a section A-A in FIG. one; in fig. 3 is a partial section BB of FIG. 1. The universal joint consists of forks 1 and 2 mounted on the connecting shafts 3 and 4 and interconnected by a cross-piece 5, the pins of which are included in the eyes of the forks. On the cylindrical surface of the trunnion trunnion 5 mounted bushings 6, and on the ends - flat plates 7, and both of them are made of laminated rubber-metal elements. In the eyes of the forks 1 and 2, glasses 8 are installed, fixed with screws 9. Flat washers 7 at the ends of the trunnion trunnions are fixed from axial displacement using caps 10,
