Description

-. I. Изобретение относитс к машиностроению. Известна упруга муфта, содержаща две фланцевые полумуфты с пальцами, взаимодействующие через упругий диск 1.-. I. The invention relates to mechanical engineering. A known elastic coupling comprising two flange coupling halves with fingers interacting through the elastic disk 1.

Известна упруга муфта, содержаща две полумуфты с торцовыми пальцами и упругий элемент в виде пружины кручени , установленный между полумуфтами и закрепленный в нажимных рычагах 2.A known elastic coupling comprising two coupling halves with end fingers and an elastic element in the form of a torsion spring mounted between the coupling halves and secured in the pressure levers 2.

Недостатком этой муфты вл етс небольша надежность, плохие антивибрационные свойства.The disadvantage of this coupling is its low reliability, poor anti-vibration properties.

Цель изобретени - повыщение надежност муфты.The purpose of the invention is to increase the reliability of the coupling.

Это достигаетс тем, что муфта снабжена квадратной металлической обоймой, охватьшающей упругие элементы и рычаги, при этом рьгааги установлены между упругими элементами и втулками.This is achieved by the fact that the coupling is provided with a square metal cage, which covers the elastic elements and levers, while the belts are installed between the elastic elements and the sleeves.

На фиг. 1 показана муфта, разрез; на фиг 2 - разрез А-А на фиг. 1.FIG. 1 shows a clutch cut; FIG. 2 is a section A-A in FIG. one.

Муфта содержит ведущую полумуфту I и ведомую полумуфту 2, во фланцах которых в диаметральной плоскости запрессовано поThe clutch contains the leading half coupling I and the driven coupling half 2, in the flanges of which are pressed in the diametral plane.

.два пальца 3 и 4 с установленными на них втулками 5. Пальцы 3 в полумуфте 1 расположены по окружности Д,, а пальцы 4 в полумуфте 2 - по окружности Д,. При этом диаметр Д, больше диаметра Д,, так что при повороте полумуфт 1 и 2 относительно друг друга их пальцы 3 и 4 с втулками 5 не задевают друг друга. Пальцы 3 и 4 полумуфт 1 и 2 соединень между собой опирающимис на их втулки 5 жесткими нажимными рычагами 6 и 7, вьшолненными в виде пластин. Полумуфты 1 и 2 имеют цилиндрические фланцы одинакового диаметра Д с буртами 8 на наружных торцах . Муфта снабжена квадратной металлической обоймой 9, охватывающей нажимные рычаги .two fingers 3 and 4 with sleeves 5 mounted on them. Fingers 3 in coupling half 1 are located around circle D, and fingers 4 in coupling half 2 - around circle D ,. The diameter D is larger than the diameter D ,, so that when rotating the coupling half 1 and 2 relative to each other, their fingers 3 and 4 with sleeves 5 do not touch each other. The fingers 3 and 4 of the half couplings 1 and 2 are interconnected by rigid pressure levers 6 and 7 supported on their bushings in the form of plates. Half couplings 1 and 2 have cylindrical flanges of the same diameter D with shoulders 8 on the outer ends. The clutch is equipped with a square metal yoke 9 covering the push levers.

5 6, 7 и фланцы Д полумуфт 1 и 2.5 6, 7 and flanges D half couplings 1 and 2.

Claims

Inside the square sleeve, between its walls and levers 7 and 8, resilient elements 10 and I are arranged in the form of rectangular shaped bars or a set of plates. The slew 9 is freely banged on the half couplings 1 and 2 and is kept from axial displacement by the pins 8. The clutch works as follows. .-, 3 71 When the coupling half rotates, for example clockwise, it pushes the fingers 3 onto the plates 6 and 7, which is transmitted through the elastic elements 10, 11 and the ring 9 to the fingers 4 of the coupling half 2, after its rotation. In this case, under the action of a circumferential force, the elastic elements 10, 11 are evenly compressed, which ensures the elasticity of the load transfer between the coupling halves. By increasing the volume of elastic elements of the air jaciaieT, the power consumption of the coupling and, consequently, its reliability. Invention Formula Elastic Coupling, containing two flange coupling halves, fingers with bushings, mounted

on the ends of the coupling halves, as well as elastic elements and levers placed between the coupling halves, characterized in that, in order to increase reliability, it is equipped with a square metal yoke covering the elastic elements and levers, while the levers are installed between the elastic elements and bushings .
