The invention relates to general engineering, serves to connect shafts and transmit torque with the measurement of its magnitude.

The purpose of the invention is to increase the accuracy of transmission and torque measurement.

FIG. 1 shows a schematic of a coupling; figure 2 - groove.

The coupling contains two coupling halves 1 and 2 mounted on the shafts with corresponding flanges 3 and 4, a connecting sleeve 5 with flange 6, a means of measuring torque, including a measuring scale 7 installed parallel to the axis of the coupling, two cylindrical springs 8 and 9 placed respectively between flanges 3, 6 and 4, 6. In this case, the sleeve 5 is connected to the coupling half 1 by the splines 10, and with the coupling half 2 by means of 2 triangular grooves 11 diametrically located on the coupling half and the protrusions 12 corresponding to them on the sleeve 5.

To measure the torque, the clutch is tared statically — one shaft (half-coupling) is stopper t, and the other is loaded with a lever and scale with a torque from Scale 7, graduated with units of torque, based on the ratio

where M is the moment transmitted by the clutch;

F - spring compressive force;

g - the shoulder of the moment;

Q - the angle of the side walls

grooves;

d is the inner diameter of the sleeve 5; h - height of protrusions 12 “When transmitting torque, half coupling 1 through coupling sleeve 5 transmits rotation of coupling half 2o. As a result of interaction of the projections 12 sleeve 5 with the walls of triangular grooves 11 on coupling half 2, the moment 5 and flange 6

The sleeve moves until the effective axial force and the force of compression of the spring 8 are balanced by the force of compression of the spring 9. The clutch takes the position corresponding to the transmitted moment. The magnitude of the moment is determined by the relative position of the scale 7 and flange 6

Coupling the sleeve with the half coupling through protrusions and grooves, springing the screw / axle along the axis of the coupling allows the sleeve to move almost instantly in response to the torque, while the amount of movement is linearly fixed on the scale by the sleeve flange without any intermediate links.
