Изобретение относитс к машиностроению и, в частности, к приборостроению.This invention relates to mechanical engineering and, in particular, to instrument making.

Известна муфта, содержаща две полумуфты , взаимодействующие через промежуточный элемент I.A clutch is known, comprising two coupling halves interacting through an intermediate element I.

Недостатком ее вл етс больщой вес.Its disadvantage is a large weight.

Известна муфта, содержаща две полумуфты с радиально закрепленными на торцах упругими пластинами, расположенными взаимно перпендикул рно и.взаимодействующими через промежуточный элемент 2.A clutch is known, comprising two coupling halves with elastic plates radially fixed at the ends and arranged mutually perpendicularly and interacting through the intermediate element 2.

Данное устройство вл етс наиболее близким к изобретению по технической сущности и достигаемому результату.This device is closest to the invention in its technical essence and the achieved result.

Недостатком его вл етс сложность конструкции .The disadvantage of it is the complexity of the design.

Цель изобретени - упрощение конструкции .The purpose of the invention is to simplify the design.

Это достигаетс тем, что промежуточный элемент выполнен в виде кольца с четырьм симметрично расположенными V-образными пазами, г концы упругих пластин выполнены разрезными и отогнутыми средней частью к промежуточному элементу, при этом последние размещены в его пазах.This is achieved by the fact that the intermediate element is made in the form of a ring with four symmetrically arranged V-shaped grooves, the ends of the elastic plates are made split and bent away from the middle part to the intermediate element, while the latter are placed in its grooves.

На фиг. 1 изображена муфта, общий вид, в осевом разрезе; на фиг. 2 - вид по стрелке А на фиг. 1.FIG. 1 shows the coupling, general view, in axial section; in fig. 2 is a view along arrow A in FIG. one.

Полумуфты 1 и 2 закреплены на концах валов 3 и 4. На торце полумуфты 1 закреплена упруга пластина 5, а на торце полумуфты 2 - упруга пластина 6. Полумуфты 1 и 2 установлены так, что их пластины 5 и 6 развернуты одна относительно другой на 90°.Half coupling 1 and 2 are fixed at the ends of the shafts 3 and 4. At the end of coupling half 1, an elastic plate 5 is fixed, and at the end of the coupling half 2 - an elastic plate 6. Half coupling 1 and 2 are installed so that their plates 5 and 6 are turned relative to each other 90 °

Между полумуфтами 1 и 2 наход тс кольцо 7 с четырьм V-образными пазами 8. В эти пазы вставлены отгибы 9 и 10 пластин 5 и 6. Отгиб 9 и 10 выполнены так, что в свободном состо нии они имеют угол меньще 90°, так что при вставке их в пазы 8 необходимо их дополнительно подог5 нуть в пределах упругой деформации. Вставленные в пазы 8 отгибы 9 и 10 стрем тс выпр митьс и прижимаютс к боковым поверхност м V-образных пазов 8.Between coupling halves 1 and 2 there is a ring 7 with four V-shaped grooves 8. Folds 9 and 10 of plates 5 and 6 are inserted into these grooves. Bend 9 and 10 are made so that in the free state they have an angle of less than 90 °, so that when inserting them into the grooves 8 it is necessary to additionally adjust them within the limits of elastic deformation. The folds 9 and 10 inserted into the grooves 8 tend to straighten out and press against the side surfaces of the V-shaped grooves 8.

Claims

The clutch works as follows. 0 When the shaft 3 rotates, the half coupling 1 with the help of plate 5 and its bends 9 passes through the grooves 8 rotation of the ring 7, the latter through the grooves 8, rotated 90 °, transmit 6 rotation through the bends 10 of the plate 6 of the coupling 2 to the shaft 4. Since the plates 5 and 6 with 9 and 10 spring limbs, a gap in the grooves 8 of the ring 7 is guaranteed to be chosen, a backlash-free connection of shafts is ensured. The half-couplings deployed one relative to the other by 90 ° clarify the compensation of ceres and shaft misalignment. The coupling ensures reliable exact connection of the two shafts, eliminates the influence of their misalignment and misalignment, thereby ensuring reliable operation leading to the rotation of the mechanism.
