Description

The invention relates to mechanical engineering and can be used in all sectors of the national economy to connect the shafts of machines and mechanisms with noBbmieHHbix requirements for durability and coupling dimensions, preferably in cases of a flanged, self-centering engine with an executive machine.

The purpose of the invention is to increase the durability of the structure.

FIG. 1 shows the coupling, axial section J in FIG. 2 is a section A-A in FIG. 1j in FIG. 3 is a section BB in FIG. 1.

The elastic coupling contains a leading cam half coupling 1, rigidly connected with the driving shaft 2 by means of a pin 3, a driven cam half coupling 4, rigidly connected with the driven shaft 5 by means of a pin 6, and an elastic connecting element in Bi-nee sprocket and 7. The leading coupling half 1 is installed coaxially with the driven half coupling 4 at the end of the driven shaft 5, in the end of which there is a diametrical groove 8 and a central hole 9. The end of the driving shaft 2 is located in the center of the hole nominal 9, and the leading coupling half 1 is installed with the possibility of limited rotation relative to the driven shaft 5. Pins 3 and 6 for ease of assembly are installed without tension

and are prevented from falling out by spring rings 10.

The clutch works as follows. When the drive shaft 2 rotates, the torque is transmitted through pin J 3 to the driving coupling half 1, then through the elastic star 7 to the driven coupling half 4 and through the pin 6 to the driving shaft 5.

 О Since the width of the diametrical groove at the end of the driven shaft is much larger than the diameter of the pin connecting the coupling half with the coupling

shaft, the leading coupling half is rotated relative to the known shaft and respectively driven half coupling, which ensures the normal operation of the elastic element, thus excluding the effect on the elastic element of forces arising from distortions of the shaft axes.

Due to the coaxial installation of the drive and driven half coupling at the end of the driven shaft, the diametral groove of the central hole in the end of the driven shaft, the location of the end of the drive shaft in the central hole and the installation of the drive half coupling with the possibility of limited rotation relative to the driven shaft, increases the service life of the elastic element and durability of the structure as a whole.
