Description

Изобретение относится к машино строению.The invention relates to a machine structure.

Известны упругие втулочно-пальцевые муфты, состоящие из двух полумуфт_лсоединенных между собой пальцами с упругими втулками, которые выполнены в виде резиновых колец трапецеидального сечения [1].Known elastic sleeve-finger couplings, consisting of two coupling halves _l connected by fingers with elastic sleeves, which are made in the form of rubber rings of trapezoidal section [1].

Недостатком этих муфт является малая опорная поверхность втулок по на-* ружному диаметру.The disadvantage of these couplings is the small bearing surface of the bushings on the outside diameter.

Наиболее близкой по технической сущности и достигаемому результату является «упругая втулочно-пальцевая муфта, содержащая две фланцевые по- 15 лумуфты, соединенные между собой пальцами со смонтированными на них упругими элементами [2].The closest in technical essence and the achieved result is an “elastic sleeve-finger coupling containing two flange half-couplings connected by fingers with elastic elements mounted on them [2].

Недостаток муфты состоит в том, что ее конструкция сложна, и она име-г 20 ет недостаточные упругие свойства.The disadvantage of the coupling is that its construction is complex and it has insufficient elastic properties.

Цель изобретения — повышение компенсационных свойств.The purpose of the invention is to increase the compensatory properties.

Поставленная цель достигается тем, что упругие элементы выполнены в ви- 75 де набора тонкостенных втулок, расположенных концентрично с зазором относительно друг друга, и колец, установленных в зазорах между втулками поочередно с противоположных торцов ‘ 30 втулок, при этом ширина каждого кольца меньше половины длины втулки.This goal is achieved by the fact that the elastic elements are made in the form of a set of thin-walled bushings arranged concentrically with a gap relative to each other, and rings installed in the gaps between the bushings alternately from opposite ends of the '30 bushings, while the width of each ring is less than half the length bushings.

На фиг. 1 изображена муфта, продольный разрез; на фиг. 2— упругий элемент, узел I.In FIG. 1 shows a coupling, a longitudinal section; in FIG. 2 — elastic element, node I.

Упругая втулочно-пальцевая муфта содержит полумуфты 1 и 2, взаимодействующие между собой с помощью пальцев 3, жестко установленных на одной из полумуфт, например на полумуфте 1 и упругих элементов 4. Упругие элементы 4 выполнены в виде набора тонкостенных втулок 5, расположенных концентрично одна в другой с'зазоромThe elastic sleeve-finger coupling contains half-couplings 1 and 2, interacting with each other using fingers 3, rigidly mounted on one of the half-couplings, for example, on the half-coupling 1 and elastic elements 4. The elastic elements 4 are made in the form of a set of thin-walled bushings 5 located concentrically one in another with a clearance

6. В зазорах 6 поочередно с противоположных торцов втулок 5 установлены к оль ца 7.6. In the gaps 6 alternately from the opposite ends of the bushings 5 are installed to the ring 7.

Подобное выполнение упругих элементов упрощает конструкцию и повышает упругие свойства муфты.Such a design of elastic elements simplifies the design and improves the elastic properties of the coupling.

Claims

The invention relates to mechanical engineering. Elastic sleeve-finger couplings are known, consisting of two half-couplings interconnected by fingers with elastic bushings, which are made in the form of rubber rings of trapezoidal section 1. The disadvantage of these couplings is the small surface of the bushings along the outer diameter. The closest to the technical essence of the achieved result is an "elastic bushing-finger coupling, containing two flange coupling halves, interconnected by fingers with elastic elements mounted on them or 2. The lack of a clutch is that its structure is complex and it has insufficient elastic properties. The purpose of the invention is to increase the compensation properties. The goal is achieved by the fact that the elastic elements are made in the form of a set of thin-walled bushings arranged concentrically with a gap relative to each other, and rings installed in the gaps between the bushings alternately from opposite ends of the bushings, while the width of each ring is less than half the length of the sleeve. Nafig 1 shows a coupling, a longitudinal section; in fig. 2 is an elastic element, node I. The elastic sleeve-finger coupling contains coupling half 1 and 2, interacting with each other using fingers 3 rigidly mounted on one of the coupling half, for example on coupling half 1 and elastic elements 4. Elastic elements 4 are made in the form of a set thin-walled sleeves 5 arranged concentrically one into the other with a gap 6. In the gaps 6, alternately from opposite ends of the sleeves 5 are installed to the OL 7. This similar implementation of elastic elements simplifies the design and improves the elastic properties of the coupling. Claims of the invention The elastic sleeve-finger coupling comprising two flange coupling halves interconnected by fingers with elastic elements placed on them, characterized in that, in order to increase the compensation
