Description

Изобретение касаетс машиностроени и может быть использовано дл сочленени валов то , ных приборов и механизмов, а такжв-может быть применено, например, дл соединени этсчетного вала механизма с ротором электрического 5 датчика, если необходимо компенсировать ошибки датчика, возникающие в результате наличи ошибок положени отсчетного вала вследствие погрешностей изготовлени вышеупом нутого механизма, взаимных смешений и пе-ю рекосов соедин емых валов, а также электрических погрешностей самого датчика.The invention relates to mechanical engineering and can be used for articulating the shafts of these instruments and mechanisms, as well as can be used, for example, to connect this shaft of the mechanism with the rotor of the electric sensor 5, if it is necessary to compensate for sensor errors resulting from the presence of shaft due to manufacturing errors of the aforementioned mechanism, mutual mixing and the flow of reclos of the connected shafts, as well as electrical errors of the sensor itself.

Известна компенсирующа муфта, в которой соединительный элемент, св зывающий между собой две полумуфты, закрепленные 5 на сочлен емых валах, выполнен в виде установленного на одной из полумуфт ползуна, перемещаемого в диаметральном направлении кулачком и снабженного клином, преобразующим перемещение ползуна в угол пово- jO рота второй полумуфты.A compensating coupling is known, in which the connecting element interconnecting two coupling halves fixed 5 on the articulated shafts is designed as a slider mounted on one of the half couplings, moved in the diametrical direction by a cam and fitted with a wedge, which turns jO the company is the second half coupling.

Однако у такой муфты используютс пр молинейные направл ющие, в которых наличие зазора отрицательно вли ет на точность paujT- муфт, особенно малогабарит- 35However, this clutch uses straight-line guides, in which the presence of a gap adversely affects the accuracy of paujT-couplings, especially small-sized

ных. Стремление же уменьшить гказаннь Й зазор приводит к увеличению работы трени и износу направл ющих.of The desire to reduce the same gap leads to an increase in the work of the friction and the wear of the guides.

Цель изобретени - повышение точности и износоустойчивости муфты. Дл этого соединительный элемент .выполнен в виде установленного в отверстии ведущей полумуфты коромысла, одно плечо которого пмеет форму рычага, контактирующего с кулачком, а другое - выполнено в виде эксцентрика, вход щего в паз, предусмотренный в ведомой полумуфте.The purpose of the invention is to improve the accuracy and durability of the coupling. For this purpose, the connecting element is made in the form of a rocker arm mounted in the hole of the coupling half, one shoulder of which has the shape of a lever in contact with the cam, and the other is made in the form of an eccentric that fits into the groove provided in the driven coupling half.

На чертеже показана предлагаема муфта.The drawing shows the proposed coupling.

Она содержит полумуфты 1 и 2, закрепленные на сочлен емых валах 3 и 4, соответственно , и соединительный элемент 5, имеющий вид коромысла.It contains coupling halves 1 and 2 fixed on articulated shafts 3 and 4, respectively, and connecting element 5, having the form of a rocker arm.

Ось 6 качани коромысла расположена н ведущей полумуфте 1,The axis 6 of the swing of the rocker is located on the leading half coupling 1,

Одно плечо коромысла - рычаг 7, находитс в контакте с кулачком 8, закрепленным на корпусе 9,One arm of the rocker arm, the lever 7, is in contact with the cam 8 attached to the housing 9,

Claims

The necessary force to press the lever 7 to the cam 8 is created by the spring 10. The other arm of the rocker arm is made up in the form of an eccentric 11, without a gap entering the groove 12 of the driven half-coupling. The work of the compensating coupling is as follows. The rotation of the drive shaft 3 and the half coupling 1 is transmitted to the half coupling 2 and the driven shaft 4 through the axis 6 and the eccentric 11, the angular position of which relative to the coupling half 1 is determined by the cam 8 and the lever 7 pressed to it by the action of the spring 1O 7. The movement of the lever 7 around the axis 6 arises when the coupling half is rotated relative to the fixed cam 8, the eccentric 11 is transferred, which moves relative to axis 6 along an arc of a circle with a radius equal to the eccentricity between axis 6 and the axis of the eccentric 11, the tangential component of the movement of the eccentric a, directed perpendicular to the line connecting the axis 6 and the axis of the shaft 4, causes an additional angular displacement of the driven coupling half 2 by the amount of the correction angle corresponding to the total angular fitting of the driven shaft 4. The formula of the invention The compensating coupling containing the driving and driven coupling half, mounted on the respective shafts and interconnected by a connecting element, as well as a rigidly fixed cam, characterized in that, in order to increase the accuracy and wear resistance of the coupling, the connecting element n a, tanovlenii in the hole leading half of the coupling rocker, one arm of which lever has a shape in contact with the cam, and the other is designed as a cam, entering the recess provided in the driven coupling half.
