Description

one

The invention of firewalls to the field of applied mechanics, in particular to units and parts of machines, is intended for use in drives of mechanisms and machines operating with a load that varies rapidly in time, for example, in drives with internal combustion engines.

Couplings are known that contain two concentric mounted half couplings, connected by a calibrated spring, inclined mounted relative to the coupling axes and located in the cavity between the half couplings.

The disadvantage of the known mufg is their low reliability and short life,

The purpose of the invention is to increase the reliability and durability of the coupling.

This is achieved by the fact that the clutch is equipped with a second calibrated spring, while on the coupling halves there are hinges with limitations on the amount of compression of the springs.

FIG. 1 schematically shows the elastic coupling; in fig. 2, section A-A in FIG. one; in fig. 3 curve, characterizing the stiffness of the coupling.

Mufga consists of two half couplings 1 and 2, one of them is used as a disk with a clamp rigidly fixed. ea-JT / 3. A friend of a half-mug looks like

When the coupling is in operation for a year, the action of the force points of the resistance and the BELT reakda turns the half coupling 1 (in the direction of Lenin, indicated by the arrow) relative to the coupling half 2. At the same time, as the angle U increases with respect to the rotation of coupling half and 1, it increases. compressive forces of the spring 5 are simultaneously reduced with a simultaneous decrease; shoulder of these forces relative to the axis of the shaft 3. As a result, the clutch has the form shown in FIG. 3. From here it follows that the stiffness of the coupling with f decreases as the relative angle P of the coupling half 1 and 2. In the area of maximum characteristics, the coupling has a very low rigidity close to zero. This allows it to effectively dampen tremors. shocks and resonant vibrations. When the overload mode is reached, the limiters 7 of the amount of compression of the springs 5 come into contact and the mufga begins to work as rigid. Claims of the invention The elastic coupling consists of two half-couplings installed cononetically, with a calibrated spring inclined in relation to the axes of the coupling and located in the cavity between the coupling half, so that, in order to increase reliability and durability, the coupling is equipped with a second calibrated spring, while on the coupling halves there are hinges with limiters for the amount of compression of the springs.
