The innovation is therefore based on the task of creating an elastic coupling for the transmission of a torque between two parallel shafts, but not coaxial anoröaeten shafts, they have disadvantages of the. ... _;

known designs avoids. , ".. J

This object is achieved according to the invention in that each of the two shafts has a fixed coupling flange """\

is connected, with two applied pins j

a turnstile connected via elastic sleeves stands that when the torque is transmitted to pressure and.:;

■ ι b @ i a deviation of the two waves from the coaxial ' The position is subject to shear stress, with the two axes of the gusansnengehSrenden tenons perpendicular to the axis of the waves.

With such a design, the sliding movement of parts on other parts (as occurs with <? Er Oldhaa coupling) is differentiated, so that the disadvantages associated therewith do not apply. On the other hand, the shafts deviate from the coaxial coupling with the new coupling location only very small radial stresses on these waves result. The innovation-fitting coupling also allows an angular mutual displacement of the two shafts.

An exemplary embodiment of the innovation is illustrated in the drawing. Show it

The illustrated elastic coupling contains a tarpaulin 1 in a central bore 2 for receiving the end of a shaft 8, which is wedged in a groove 3 and in a ferrule 4 provided with a faulty 5 by means of a screw 6 and a nut 7 Is braced - Eis Plansch § has a zaatrale conical bore OK, which receives the other shaft Ii, which is wedged in a groove 12. The flange 2 has on its circumference two elongated holes 13 and 1, which are provided with semicircular fillets and which - in relation to the length of the flange - systematically cu two additional, also semicircular rounded kangal holes ϊ3a, 1Ά &. lie. These long viewers enable the coupling to be precisely adjusted in terms of angle.

The elastic coupling described enables the transmission of a torque between two but coaxially arranged shafts, for example the Weil © 8 sui? Wave ti. The radial displacement of pins 18 and 23 with respect to the shoulders 1? and 2 * 1, elastic sleeves 20 and 25 are made possible, which experience a certain amount of shear stress and thus allow deviations of the two W © 11 © & from the coaxial position.
