Abstract

Изобретение относитс к машиностроению, в частности к карданным шарнирам переднего конца кардонной передачи. Цель изобретени - повышение долговечности. Шарнир содержит фланцевую вилку 1, крестовину 2, подшипники 3, шлицевую вилку 4 и корпус 5. Шлицева вилка 1 выполнена с торсионным участком 9. Корпус 5 выполнен в виде кольца 15, охватывающего проушины 11 вилок 1, 4 и снабженного поворотными опорами 17, ориентированными радиально к центру шарнира. Вилки 1, 4 снабжены радиально расположенными плоскими пружинами 14. Кажда опора 17 выполнена с двум охватывающими соответствующую пружину 14 выступами 20, поверхности которых выполнены сферическими. При изменени х нагрузки измен етс угол разворота между корпусом 5 и вилкой 1, изгибаютс плоские пружины 14, измен рассто ние от центра шарнира до точки контакта пружин со сферическими поверхност ми выступов 20 опор 17, что нарушает услови возникновени крутильных колебаний, т.е. обеспечивает повышение долговечности шарнира в целом. 3 ил.The invention relates to mechanical engineering, in particular, to cardan joints of the front end of a cardon gear. The purpose of the invention is to increase durability. The hinge contains a flange plug 1, a cross piece 2, bearings 3, a splined fork 4 and a housing 5. The slotted fork 1 is made with a torsion section 9. The housing 5 is made in the form of a ring 15, covering the lugs 11 of the forks 1, 4 and equipped with pivoting bearings 17 oriented radially to the center of the hinge. The forks 1, 4 are provided with radially arranged flat springs 14. Each support 17 is made with two protrusions 20, which cover the corresponding spring 14, and whose surfaces are spherical. When the load changes, the angle of rotation between the housing 5 and the fork 1 changes, the flat springs 14 bend, changing the distance from the center of the hinge to the point of contact of the springs with the spherical surfaces of the projections 20 of the supports 17, which violates the condition of torsional vibrations, i.e. provides increased durability of the hinge as a whole. 3 il.

Claims

Claim

The cardan joint of the predominantly front end of the cardan transmission, comprising a flange plug connected to the output shaft of the gearbox including eyelets and a flange and connected to the spline fork by means of a spider and needle bearings, characterized in that, in order to increase durability, it is provided with four supports, four flat springs and a housing made in the form of a ring with a flange connected to the output shaft of the gearbox, and inside the ring, covering the eyes of both forks, are installed with By rotation around its own axes, four supports uniformly arranged around the circumference and directed towards the center of the hinge, each of which is made with two protrusions, the counter-located surfaces of which are made spherical, the flange fork is made with a torsion section located between the flange and the eye base, and each of the forks made with flat springs fixed on the outer surfaces of the eyes and located in the longitudinal plane, installed with the possibility of interaction with spherical surfaces of supports.
