Description

one

The invention relates to mechanical engineering.

A resilient safety clutch is known, containing a leading and driven side of the sleeve and an elastic plate connecting them, fixed at one end on the drive half coupling and the other resting on the pin of the driven coupling

The disadvantage of this coupling is its low sensitivity and low load capacity.

The closest technical solution is an elastic-safety coupling, containing two coupling halves, connected by a torsion spring placed on the pin, s & k on the flange of the leading coupling flange, and resting the ends on the end pins of each half of the coupling

The disadvantage of this clutch is its low load capacity and & due to incomplete use of the spring carrying capacity due to the fact that its end rests on the shaft of the drive coupling half.

The aim of the invention is to increase the load capacity of the clutch due to the use of the carrying capacity of the springs.

To do this, radial grooves are made at the end of the leading coupling half, and

The driven half coupling is equipped with a rod interacting with the other end of the spring, while the finger with the spring is mounted in the front groove of the driving half coupling and is placed between the pin and the stem. Pin rod

and the finger may be located in a flat, passing through the axis of the coupling. FIG. 1 shows the proposed coupling, a longitudinal section; in fig. 2 something from the end with a partial cross-section.

The clutch contains the master 1 and the slave 2

coupling halves, which are interconnected by torsion springs 3. Half coupling 1 has an annular protrusion 4 in which the end pairs 5 are made. At a distance And from one

of the faces of the grooves 5, which are a little more than half the diameter of the springs, fingers 6 are pressed evenly around the circumference. Springs 3 are freely installed on them, the ends of which in the undeformed COCTOHIHIH are parallel to the face m 7 of the end grooves 5, which exclude circular rotation of the springs when they are not in contact with pin 8 and rod 9 and when triggered at the time of overloads. Slave popumufta 2 on the circumference of the pressed pin

8 and the rod 9 are of different lengths, they are located on both sides of the finger with a spring and may be in a plane that runs through the axis of the coupling. On pin 8 and rod

The ends 10 and 11 of the springs 3 are supported, which, under load, form an angle between them. The width of the tft grooves 5 allows the deformation of the springs to an angle about O.

The clutch operates as follows. When rashesININ the leading popumufta i, for example, counterclockwise, are mounted on its axles of the spring 3 with their ends

10 and 11 exert pressure on the pin 8 and the rod 9 of the driven half-coupling 2, under the action of which it comes into motion, the deformation of the springs 3 ensures the elasticity of the transfer of the load. When the clutch reaches the torque limit, the deformation of the springs

3, reaches such a value that they are free to pass with their ends 10 and 11 between the f v pins 8 and the rods 9, ex; In this, the ends of the springs 3 are disengaged from them. The clutch is activated. Passing the pin 8 and the rods 9, the rings Yu and 11 of the springs 3 are located in the original position and, when the overload is removed, they enter into locking with the pins 8 and 9 rods 9 encountered in their way, and the overload will not be eliminated. Coupling moment increases

Due to the fact that the force is developed by the reel springs at its ends, it is completely transmitted to the popumuft driven slave due to the presence of a second row of rods on it.
