Description

one

The invention relates to devices for connecting coaxially rotating shafts and transmitting torque, and can be used, for example, in pump controllers for driving centrifugal angular velocity sensors.

A known elastic coupling comprising two half-couplings covering one another with radial grooves and two leaf springs fastened in the groove of the male half coupling and in contact with the inclined side surfaces of the grooves covering half coupling 1.

However, the attachment of the plate springs of such a clutch is not sufficiently reliable and makes it difficult to mount the clutch in hard-to-reach places.

The purpose of the invention is to increase the reliability of the coupling and facilitate its installation.

The goal is achieved by covering the half coupling, lamellar springs and intermediate shields with central holes, and the mount assembly of lamellar springs is made as a set of intermediate shields installed between lamellar springs, and a removable retainer placed in the holes of the half-coupling, lamellar springs and intermediate shields

FIG. Figure 1 shows the elastic coupling, the grooves of the enclosing coupling half of which are made so that the ends of the leaf springs are arranged in a melade by the projecting parts of the coupling half; in fig. 2 - elastic coupling, grooves covering the coupling half of which is made so that the ends of the leaf springs are located on both sides of the protruding parts; in fig. 3 is a section along A-A in FIG. 2

The clutch contains male 1 and female 2 coupling halves, as well as two leaf springs 3 fixed in the groove of coupling half 1 by intermediate shields 4 and removable retainer 5. Clamp 5 is held

in the central hole of the half coupling 1 by the stops 6. The ends of the leaf springs 3 are in contact with the inclined surfaces of the projections 7. The groove width of the half coupling 1 and the dimensions of the projections 7 of the half coupling 2 are made according to the condition of a given amount of deflection from the nominal torque transmitted by the coupling. On steady-state clutch operation

smooth transfer of torque from one coupling half to the other and equalization of the angular velocity due to the elastic deformation of the leaf springs 3.

With a sharp change in torque,

for example, in modes of movement or acceleration, it is ensured that it is smoothly unstressed and is not subject to torque due to the additional elastic deformation of the leaf springs 3.
