Изобретение относитс к области машиностроени , а именно дл соединени валов, работающих под большим углом изгиба и передающих больише крут щие моменты.The invention relates to the field of engineering, namely for connecting shafts operating at high bending angles and transmitting high torques.

Известно шарнирное соединение, состо щее из двух полумуфт, жестко смонтиро ванных на соедин емых валах Г1.A swivel joint is known, consisting of two coupling halves rigidly mounted on connected G1 shafts.

Недостатком ycTpolteTBa вл етс наличие точечных контактов, что не обеспечивает работу с большим крут шим моментом, The disadvantage of ycTpolteTBa is the presence of point contacts, which does not provide work with high torque,

Известно и другое шарнирное соединение, содержащее жестко смонтированные на соедин емых валах две полу муфты, перва из которых имеет шаровые головки, вход щие в сферические гнезда второй полумуфты, а также устройство дл фиксации шаровой головки, расположенной по оси вала, и каналы дл подвода смазки 2.Another swivel joint is known that contains two semi-couplings rigidly mounted on the connecting shafts, the first of which has ball heads entering the spherical sockets of the second coupling half, as well as a device for fixing a spherical head located along the shaft axis and channels for supplying lubricant 2

Данное устройство вл етс наиболее близким к изобретению по технической сущности и достигаемому результату.This device is closest to the invention in its technical essence and the achieved result.

Недостатком его вл етс малый угол изгиба, низка надежность соединени валовThe disadvantage of it is a small bend angle, low reliability of the shaft connection

Целью изобретени вл етс упрощение конструкции, обеспечение надежной фиксации The aim of the invention is to simplify the design, ensuring reliable fixation

соедин емых валов, увеличение угла изгиба и повышение работоспособности.connected shafts, increased bending angle and increased efficiency.

Указанна цель достигаетс тем, что втора по умуфта выполнена с пазом в диаметральной плоскости и каждое из сферических гнезд выполнено в виде двух полусфер, имеющих плоские наружные поверхности, контактирующие со стенками паза второй полумуфты , кроме того, шаровые головки в теле полумуфты закреплены неподвихшо, а устройство дл фиксаш и шаровой головки по оси вала выполнено в виде стопорных пальцев, расположенных в плоскости оси вала и перпендикул рно к последней.This goal is achieved by the fact that the second coupling is made with a groove in the diametrical plane and each of the spherical sockets is made in the form of two hemispheres with flat outer surfaces in contact with the walls of the groove of the second coupling half; The device for fixing and ball head along the shaft axis is made in the form of locking pins, located in the plane of the shaft axis and perpendicular to the latter.

На фиг. 1 изображен общий вид щарнирного соединени в разрезе; на фиг. 2 - разрез по А-А на фиг. 1; а фиг. 3 - разрез по Б на фиг. 1,FIG. 1 shows a general view of a hinge joint in section; in fig. 2 is a section along A-A in FIG. one; and FIG. 3 shows a section along B in FIG. one,

Шарнирное соединение включает в себ две полумуфты 1 и 2, жестко смонтированные на соедин емых валах 3 и 4.The hinge includes two coupling halves 1 and 2 rigidly mounted on the connecting shafts 3 and 4.

Claims

The semi-coupling 1 has ball heads 5, half-couplings 2 entering the spherical sockets 6, made in the form of two hemispheres with flat outer surfaces. One of the ball heads 5, located on the axis of the tepec of the clutch 1, is fixed immobile, and the device for fixing the ball hinge is made in the form of locking fingers 7 located in the plane of the shaft axis and perpendicular to the latter. Half coupling 2 is made with a groove in the diametral plane, which includes spherical sockets of 6 ball heads. In the body of the ball heads 5, channels 8 are provided for supplying lubricant. The sockets 6 contain oil lines 9 and annular gaskets 10 with springs. Fixing the ball head 5 located along the axis of the shaft simultaneously ensures fixation of the connected shafts. The ball heads 5, located outside the axis of rotation of the hinge and bearing sockets 6, in reciprocating and rotating movement along the groove of the half-coupling 2, transfer the torque smoothly when the hinge joins. To provide the assembly and the desired bending angle of the shafts operating both in the same plane and in space, the sockets 6 are concave hemispheres, truncated in a plane perpendicular to the axis of rotation of the hinge. Spacing plugs 9 and annular gaskets 10 with springs serve to slow down the oil flow from the tank half of the coupling 1 coming through the channels 8 in the ball heads 5 to the working surfaces under the action of centrifugal force. The invention has a hinged joint that rigidly mounted two coupling halves mounted on connected shafts. the fact that, in order to simplify the design, to ensure reliable fixation of the connected shafts, to increase the bending angle and to increase the working capacity, the second coupling half is made with a groove in the diametral plane and to Each of the spherical sockets is made in the form of two hemispheres with flat outer surfaces in contact with the walls of the groove of the second half-coupling; the plane of the shaft axis and perpendicular to the latter.
