1one

Изобретение относитс к машиностроению , в частности к муфтам дл передачи вращени между валами, расположенными под углом, измен ющимс в диапазоне от О до 90°.The invention relates to mechanical engineering, in particular to couplings for transmitting rotation between shafts arranged at an angle ranging from 0 ° to 90 °.

Известен шарнирный механизм, содер- 5 жащий ведомый и ведущий валы и соединительный элемент между ними 1.Known hinge mechanism, containing the driven and driving shafts and the connecting element between them 1.

Недостатком данного устройства вл етс то, что соединительный элемент не обеспечивает точного зацеплени между веду- ,о щим и ведомыми валами, и следовательно, диапазон изменени углов между валами мал.The disadvantage of this device is that the connecting element does not provide accurate engagement between the drive shaft and the driven shafts, and therefore, the range of angles between the shafts is small.

Известна также углова шарнирна муфта , содержаща установленные на валах ведущую и ведомую полумуфты и проме- 5 жуточное соединительное звено 2.The angular hinge coupling is also known, containing the drive and driven coupling halves mounted on the shafts and the intermediate connecting link 2.

Недостатками известной угловой щарнирной муфты вл ютс значительные габариты му(})тьг, а также низкие эксплуатационные возможности из-за ограниченного 20 диапазона изменени углов между ведущим и ведомым валами муфты.The disadvantages of the well-known corner joint are the considerable size of mu (}), as well as low operational capabilities due to the limited range of variation of the angles between the drive and driven shafts of the coupling.

Цель изобретени - расширение эксплуатационных возможностей, а также сокращение габаритов муфты.The purpose of the invention is the expansion of operational capabilities, as well as reducing the size of the coupling.

Поставленна цель достигаетс тем, что в угловой шарнирной муфте, содержащей установленные на валах ведущую и ведомую полумуфты и промежуточное звено, промежуточное звено выполнено в виде двойного шарнирного трехзвенника типа шатунползун-шатун и самоустанавливающегос направл ющего элемента, св занного с шатунами при помощи ползунов, при этом ось симметрии направл ющего элемента совпадает с биссектрисой угла, образованного валами, а оси валов, ползунов, и упом нутого направл ющего элемента пересекаютс в одной точке в центре муфты, причем направл ющий элемент выполнен в виде кольца с наружной сферической поверхностью и направл ющими пазами под ползуны , кроме того, направл ющий элемент выполнен в виде сферы, с двум боковыми отверсти ми под ползуны, а также в виде наружного цилиндрического подшипника с внутренним кольцом, в котором выполнены радиальные отверсти под ползуны.The goal is achieved by the fact that in the angular hinge coupling, which has leading and driven half couplings mounted on shafts and an intermediate link, the intermediate link is made in the form of a double hinge three-bearing type of connecting rod-slide rod and self-aligning guide element connected with connecting rods using sliders This axis of symmetry of the guide element coincides with the bisector of the angle formed by the shafts, and the axes of the shafts, sliders, and the said guide element intersect at one point in the center of the sleeves The guide element is designed as a ring with an outer spherical surface and guide slots for the sliders; moreover, the guide element is designed as a sphere, with two lateral holes for the sliders, and also as an outer cylindrical bearing with an inner ring in which radial holes for slides are made.

Claims

FIG. Figure 1 shows an angular hinge pin in which the guide element is designed as a ring with an outer spherical surface and guide slots under the sliders; in fig. 2 shows section A-A in FIG. one; in fig. 3 - an angular hinge coupling, in which the guide element is designed as a sphere with two side openings for sliders; in fig. 4 shows a section BB in FIG. 3; in fig. 5 shows an angular swivel coupling in which the guide member is designed as an outer cylindrical bearing with an inner ring in which radial holes for the sliders are made; in fig. b - section bb in fig. 5. The corner hinge coupling includes a shaft-mounted coupling half 1 and a coupling half 2 driven on the shafts, a connecting rod 3-hinged three-linkage bearing 3 — a slider 4 — a connecting rod 5, and a guide element made in the form of a ring 6 with an outer spherical surface 7 and guide slots under the slide. FIG. 5 shows an angular hinge coupling consisting of a semi-coupling leading 1 mounted on the shafts 1 and knowing half coupling 2, three-link articulated connecting rod type 3 - slider 4 - connecting rod 5 and a guide element made in the form of an external cylindrical bearing 8 with an inner ring 9 in which radial holes for slides are made. Angular hinge coupling works as follows. Rotation from the leading half coupling 1 rotates the connecting rod 3, which through the slider 4 transmits the rotation further to the connecting rod 5. From the connecting rod 5, the rotation is transmitted to the driven coupling half 2. During rotation of the leading coupling half 1, the three-bearing connecting rod type 3 slider 4 - connecting rod 5 the driven half coupling 2, the connecting rods 3 and 5 of the three-link are converging and diverging relative to the slide 4, while the sliders 4 move in a guide element made in the form of a ring. Such a constructive implementation of the yr io hinge coupling allows the expansion of the operational capabilities of the coupling due to the possible rotation of the shafts at an angle varying in the range from 0 to 90 °. When performing an angular swivel with. the guiding elements (Fig. 3 or Fig. 5) rotation from the leading coupling half 1 to the driven coupling half 2 is transmitted in a similar way by means of the three-link connecting rod 3 - slider 4 - connecting rod 5. At that, the slider 4 moves into the hole of the guide element, which is made accordingly : in FIG. 3 - in the form of a sphere 7 with two lateral holes for slides; in FIG. 5 - in the form of an outer cylindrical bearing 8 with an inner ring 9, in which radial holes for creepers are made. Such a constructive implementation of the angular hinge clutch will reduce the dimensions of the clutch by reducing the number of three bearing parts to one. Thus, the proposed angular swivel coupling expands the operational capabilities of the clutch by expanding the range of angles between the shafts from 0 to 90 °, and also reduces the dimensions of the clutch by reducing the number of triple bolts to one. Claim 1. Angular swivel coupling, which has leading and driven coupling halves mounted on shafts and intermediate connecting link, characterized in that, in order to expand operational capabilities and reduce the size of the coupling, the intermediate connecting link is made in the form of a double hinge three-rod type -slider-rod and self-aligning guide element associated with connecting rods with the help of sliders, with the axis of symmetry of the guide element coinciding with the bisector of the angle, the image vannogo shafts and axle shafts, and slides said guide member intersect at a single point in the center of the coupling. 2.

A clutch according to claim 1, characterized in that the guiding element is designed as a sphere with two lateral holes for sliders. 4.
