1one

Изобретение относитс к машино строению и может быть использовано дл соединени .валов механизмов, передающих крут щий момент и имеющих взаимные смещени .The invention relates to mechanical engineering and can be used to connect shafts of mechanisms transmitting torque and having mutual displacements.

Известна упруга муфта, предназначенна дл работы в услови х передачи значительных крут щих моментов, перекосов и смещени валов, состо ща из ведущей и ведомой полумуфт, ,Q прижимных колец и упругих элементов в виде хомутов 1 .The known elastic coupling, designed to operate in conditions of transmission of significant torques, misalignment and displacement of the shafts, consists of driving and driven half couplings, Q clamping rings and elastic elements in the form of clamps 1.

Однако при передаме крут щего момента возникают центробежные силы, которые, деформиру упругие элементы,ts вызывают по вление осевых сил, что приводит к дополнительным нагрузкам на опоры валов и, как следствие, снижению надежности и долговечности привода .-20However, when the torque is transmitted, centrifugal forces arise which, by deforming the elastic elements, ts, cause the appearance of axial forces, which leads to additional loads on the shaft supports and, as a result, the reliability and durability of the drive.

Известна также упруга муфта, содержаща ведущу|р и ведомую полумуфты, соединенные эластичными элементами, .выполненными в виде скобообразныхAlso known is an elastic coupling containing a leading | p and a driven half-coupling coupled by elastic elements made in the form of brackets

полос из транспортерной ленты. Ступицы полумуфт снабжены центральными соосными цилиндрическими гнездами дл установленного в них упругого вклады--ша из.strips of conveyor belt. The hub half-couplings are provided with central coaxial cylindrical sockets for the elastic contributions established in them - the shaft from.

Недостатком данной упругой муфты вл етс то, что при передаче крут щего момента упругий в радиальном направлении вкладыш создает дополнительную радиальную жесткость, что :,. приводит к увеличению радиальных нагрузок на опоры валов и, как следствие , выходу их стро . Введение дополнительного элемента ведет также к усложнению конструкции.The disadvantage of this elastic coupling is that when transmitting the torque, the elastic in the radial direction creates an additional radial rigidity such that:,. leads to an increase in radial loads on the shaft supports and, as a result, their release. The introduction of an additional element also leads to a design complexity.

Цель изобретени -, увеличение надежности и долговечности работы привода путем уменьшени радиальных нагрузок на опоры валов под действием центробежных сил, а таюхе упрощение конструкции муфты.The purpose of the invention is to increase the reliability and durability of the drive by reducing the radial loads on the shaft bearings under the action of centrifugal forces, and also simplify the design of the coupling.

Claims

To achieve this goal, in an elastic coupling containing the leading and driven coupling halves, connected by means of uniformly spaced around the circumference of elastic elements of a stapled shape, the latter are mounted on the coupling halves with sequential alternation of the direction of their convexity to the axis and from the coupling axis. Figure 1 shows the clutch, a General view; figure 2 - section aa in Fig.: 1. The clutch contains a leading coupling half 1 and a driven coupling half, to which, by rings 3 and using screws 5, elastic elements 6 and 7 of a clamped shape are attached. The elastic elements b are convex outward from the axis, and the diametrically opposite elements 7 are convex to the axis of the coupling. . The clutch works as follows. During the rotation of the coupling half 1, the torque is transmitted through the elastic elements .6 and 7 to the coupling half 2. This results in centrifugal forces that tend to stretch the elastic elements 6 and compress the elastic elements 7. The forces acting on the coupling half 1 and 2 on the side of the elastic elements 6 and 7, while compensating each other. The axial forces arising from the deformation of elastic elements set outward by convexity are directed in the opposite direction to the axial forces arising from the deformation of elastic elements setted inwardly by convexity. Due to this, the forces compensate each other, i.e. the drive is discharged from additional loads and its service life increases. Claims of the invention The elastic coupling, containing the leading and driven half coupling, connected by means of uniformly circumferentially elastic elements of a stapled shape, characterized in that, in order to increase reliability by reducing the loads under the action of centrifugal forces on the supports of the connected shafts, elastic elements are mounted on the coupling halves with sequential alternation of the direction of their convexity to the axis and from the axis of the coupling.
