Abstract

The invention relates to mechanical engineering and can be used to transmit rotation from the motor shaft to the shaft of the drive mechanism, as well as to protect the latter from overload. The purpose of the invention is the expansion of operational capabilities by ensuring the connection of shafts with misalignment and non-parallelism. The leading coupling half (П) 1 is connected to П 4 by means of a holder 3 with face cams. The yoke 3 is connected to PI I by torsions 2. A mechanism is provided in the form of stoppers 5 on the yoke 3 and the thrust bearing 6 on N 4 to disconnect the clutch when triggered. Connection Y of yoke 3, torsions 2, as well as the arrangement of the shutdown mechanism on N 4 and yoke 3 ensures the operation of the coupling with significant misalignment of the connected shafts. 2 hp f-ly, 3 ill.

Description

The invention relates to machining and can be used to transfer rotation from the motor shaft to the drive mechanism, as well as to the latter from unloading.

The purpose of the invention is to enhance the ecla- utational capabilities by ensuring the connection of the shafts when they are not coaxial and non-parallel.

FIG. 1 shows the proposed coupling; on fng. 2 - driven half coupling, end view; in fig. 3 shows the node I in FIG. one.

The clutch contains the leading zero coupling 1. Connecting through torrenons 2, pressing the holder 3, with the torn cam to the guide and semi-coupling 4. The ends of the torrents 2 are located evenly around the circumference of the holder 3, the coupling half 1 and set at an angle to the axis of the coupling. The mexaini3M of the coupling has reached the inside of the radially located 1 on the oboy 3 stoppers 5 and located on the coupling half 4 of the thrust bearing 6. The radial movement of the stoners is limited to rings 7. In the omolufte 4, a stopper is mounted 8. G1ol I (1 hp) 1. can move to adjust my mite along the shafts, their position is fixed by the bolt 9.

. The flexible coupling operates in the following manner.

In the outgoing state, the cage 3 engages with the driven clutch 4 and the cams 4 and presses it against it due to the forces of the flexible flexible damping torion 2 (made of steel ropes). The rotation from the leading loumouf 1 through the torsions 2 and the cams of the holder 3 is not affected by the driven half coupling 4.

If a moment is created on the driven half coupling shaft, which exceeds the limit torque, but the yoke 3 is braked. Due to the presence of toreions and their installation, the rotational movement of the leading coupling half into the translational movement of the two axes occurs. Torsions 2, steel ropes, hvn these m are deformed, the cams 3 and the driven half coupling 4 are taken out of engagement, and the stoppers 5 iod by the action of the centrifugal force and the own air turn out of the holes of the oboy.my 3 and The bearing will continue to rotate on the bearing 6, the drive unit and the coupling half will not be rotated, as the stoppers 5 abut against the holder 6 and place the engagement rings 3 and the coupling half 4. In the holes of the toothed cage there are installed movement restrictions of the stoppers 5.

To engage the clutch, it is necessary to stop the driving zero. Coupling, clamp the mounting pin 6 with the locking screw 8 and rotate the motor shaft in the direction corresponding to

“Screwing the stoppers on. For further work, it is necessary to free the female 6 by unscrewing the locking screw 8. If it is necessary to change the muffiness of the coupling, i.e. adjust it to transmit a certain amount of rotational moment, the distance between the coupling halves is changed. To do this, unscrew the bolt 9 i-i to move one of the coupling halves along the shaft, reducing or increasing the distance a. To increase the stiffness of the coupling, the distance a is reduced. With

By this, the angle of inclination of the elastic elements to the plane is reduced, and the force required to deform the elastic elements increases.

 In the coupling design, the elastic transducer of movements must have geometrical dimensions, the ratio of which determines the transmission of torque. The limiting value of the moment transmitted by the clutch is determined by the formula

the maximum value of my torque clutch; a number of flexible elastic-winding elements;

bending stiffness of a flexible resiliently de-amplifying toreion; dia.meter toreiona; length of toreion; the radius of the toreion. Thus, the use of an elastic safety clutch for transmitting rotation from one shaft to another does not reduce the installation time in particularly difficult conditions, since there is no need for accurate alignment of shaft alignment and parallelism of the shafts; transmit rotation to vibrating objects, as well as remove engine overload protection.
