Изобретение относится к области машиностроения.The invention relates to the field of engineering.

Известны упругие втулочно—пальцевые муфты, содержащие две полумуфты, соединенные пальцами с упругими элементами [Ϊ]. Недостатком этих муфт являет- ⁵ся то, что при износе упругих элементов нельзя продлить срок их службы путем поворота.Known elastic sleeve-finger couplings containing two half-couplings connected by fingers with elastic elements [Ϊ]. The disadvantage of these couplings yavlyaet- ⁵ camping that when worn the elastic elements can not extend their service life by turning.

Известна также, упругая муфта, содержащая две фланцевые полумуфты, соединенные упругими элементами, установленными между роликами, смонтированными на пальцах одной из полумуфт, и обоймаМи, закрепленными на другой полу-₎₅муфте [2}.An elastic coupling is also known, containing two flanged half-couplings connected by elastic elements mounted between rollers mounted on the fingers of one of the half-couplings, and a clip mounted on the other half- _{) 5} coupling [2}.

Однако эта муфта имеет недостаточную нагрузочную демпфирующую способность.However, this coupling has insufficient load damping ability.

Цель изобретения - увеличение нагрузочной и демпфирующей способности муфты.The purpose of the invention is to increase the load and damping ability of the coupling.

Цель достигается тем, что муфта снабжена дополнительными упругими элементами, а ролики выполнены с наружным цилиндрическим пояском, охватывающим обойму с зазором, при этом дополнительные упругие элементы установлены в зазоре между обоймой и пояском. Кроме того, поясок и ролик могут быть выполнены за одно целое с фланцем полумуфты, а поясок ролика установлен в отверстии полу муфты.The goal is achieved in that the clutch is equipped with additional elastic elements, and the rollers are made with an outer cylindrical girdle covering the cage with a gap, while additional elastic elements are installed in the gap between the cage and the girdle. In addition, the belt and the roller can be made integral with the flange of the coupling half, and the roller belt is installed in the hole of the coupling floor.

На фиг. 1 изображена муфта, разрез; на фиг. 2 и 3 - варианты выполнения узла 1 на фиг. 1.In FIG. 1 shows a coupling, section; in FIG. 2 and 3 are embodiments of the assembly 1 in FIG. 1.

Муфта состоит из соосных фланцевых полумуфт 1 и 2, соединенных между собой упругими элементами. Во фланце полумуфты 1 равномерно по окружности Д_₽ расположены пальцы 3, на которых установлены ролики 4 с наружным цилиндрическим пояском 5. На полумуфте 2, соосно пальцам 3, закреплены обоймыThe coupling consists of coaxial flange coupling halves 1 and 2, interconnected by elastic elements. In the flange of the coupling half 1, fingers 3 are evenly spaced around the circumference of D _₽ , on which the rollers 4 with the outer cylindrical belt 5 are mounted.

6. В зазорах между деталями 4, 5 и 6 расположены упругие элементы 7 и 8, выполненные в виде сплошных или свернутых в кольцо резиновых втулок. Обойма 5 может быть установлена на полумуфте 1 в отверстии диаметром Д (фиг. 2) или выполнена за одно целое с фланцем полу муфты (фиг. 3). В последнем случае во фланце полумуфты 1 растачиваются глухие отверстия диаметром с центральным выступом Л , 5 в которых располагаются упругие элементы и пальцевые втулки. В.этом случае конструкция муфты еще более упрощается и состоит из четырех деталей - полумуфт· 1 и 2, пальцевых втулок 7 и упру- ¹⁰гих элементов.6. In the gaps between the parts 4, 5 and 6 are elastic elements 7 and 8, made in the form of solid or rolled into a ring of rubber bushings. The holder 5 can be installed on the coupling half 1 in the hole with a diameter D (Fig. 2) or made in one piece with the flange of the coupling floor (Fig. 3). In the latter case, blind holes with a diameter with a central protrusion A, 5 in which elastic elements and finger bushings are located, are bored in the flange of the coupling half 1. V.etom case clutch design even more simplified and consists of four parts - · coupling halves 1 and 2, the finger 7 and the elastic sleeves ¹⁰ GIH elements.

Муфта работает следующим образом.The coupling operates as follows.

При вращении полу муфты 1 она выступами 4 и 5 воздействует через упругие элементы 7 и 8 на обоймы 7 полумуфты 15 2, вызывая ее вращение. При этом упругие элементы 7 и 8, деформируясь, обеспечивают эластичную передачу нагрузки между полумуфтами. Так как поверхность контакта упругих элементов с деталями 20 4 и 7 возрастает за счет диаметра более чем в два раза, то увеличивается передаваемый муфтой крутящий момент.When the floor of the coupling 1 is rotated, it protrudes 4 and 5 through the elastic elements 7 and 8 onto the clips 7 of the coupling half 15 2, causing it to rotate. In this case, the elastic elements 7 and 8, deforming, provide an elastic load transfer between the coupling halves. Since the contact surface of the elastic elements with parts 20 4 and 7 increases due to the diameter more than doubled, the torque transmitted by the coupling increases.

Демпфирующая способность увеличивается за счёт увеличения объема упру- 25 гих элементов.The damping ability is increased due to an increase in the volume of elastic elements.

Claims

The invention relates to the field of engineering. Known elastic sleeve-finger couplings, containing two coupling halves, joint with fingers with elastic elements 13. The disadvantage of these couplings is that when the elastic elements are worn, they cannot be prolonged by turning. Also known is an elastic coupling comprising two flange coupling halves connected by elastic elements fitted between rollers mounted on the fingers of one of the coupling halves and the clip fixed on the other coupling half 2j. However, this clutch has insufficient load damping ability. The purpose of the invention is to increase the load and damping capacity of the coupling. The goal is achieved by providing the coupling with an additional; the fasteners are elastic, and the rollers are made with an outer cylindrical skirt that encloses the cage with a gap, while the additional elastic elements are installed in the gap between the casing and the skis. In addition, the juice and the roller can be made in one piece with the half-coupling flange, and the juice of the roller is installed in the opening of the coupling floor. FIG. 1 shows a clutch cut; in fig. 2 and 3 — embodiments of the node 1 in FIG. 1. The coupling consists of coaxial flange coupling halves 1 and 2, interconnected by elastic elements. In the flange of the half-coupling 1, evenly around the circumference D, the fingers 3 are located, on which the rollers 4 with external cy- are mounted. 5. On the half coupling 2, coaxially to the fingers 3, the clips 6 are fixed. In the gaps between parts 4, 5 and 6 there are elastic elements 7 and 8, made in the form of solid or coiled rubber bushings. The clip 5 can be mounted on the coupling half 1 in a hole with a diameter D (Fig. 2) or made in one piece with the flange of the coupling half (Fig. 3). In the latter case, blind holes D with a diameter D with a central projection are bored in the flange of the coupling half 1 which are located elastic elements and pin bushings. In this case, the design of the coupling is even more simplified and consists of four parts — half couplings 1 and 2, pin sleeves 7, and elastic elements. The clutch works as follows. When the semi-clutch 1 rotates, it acts as protrusions 4 and 5 through the elastic elements 7 and 8 on the sleeves 7. Half-couplings 2, causing its rotation. At the same time, the elements 7 and 8, which are deformed, resist, provide an elastic transfer of the load between the half-dumps. Since the contact surface of elastic elements with parts 4 and 7 increases due to diameter 1 (more than twofold), the torque transmitted by the clutch increases. The damping capacity increases due to an increase in the volume of elastic elements. Formula of the invention 1.
