Description

1

The invention relates to the field of mechanical engineering and is intended to transmit rotation from the master link to the slave.

The aim of the invention is to increase reliability by reducing the amplitude of the torsional vibrations of the connected shafts.

FIG. 1 shows the coupling, axial section; in fig. 2 is a view A of FIG. one; in fig. 3 and 4, view A in FIG. intermediate positions of the master and slave elements.

The inertia coupling has a coaxially mounted drive 1 and driven (eccentric) 2 shafts located on the same 0-0 center line. On the drive shaft, a guide 3 is fixed perpendicular to it and symmetrically about its axis, with which the centrifugal weights (sliders) 4 are located, which are located on opposite sides of the axis of rotation of the coupling. Each of the sliders with the help of a connecting rod 5 is hingedly attached to the eccentric 6 of the slave Bajja 2.

The clutch works as follows. When the drive shaft 1 rotates, the guide 3 rotates around the axis line 0-0, involving the rotation of the slide 4 around the axis line 0-0 of the connecting rod joints. Inertia forces act on centrifugal weights (slide blocks) 4 — centrifugal force and inertial force. caused by the movement of goods 4 along guide 3 (Coriolis force. These forces (without taking into account forces) determine the force interaction between guide 3, weights 4 and connecting rods 5. Forces acting on the latter, because of their inequality in the intermediate positions of the coupling and various shoulders relative to the axis of the shaft 2 create a torque on the specified shaft 2. Such movement of goods can also be characterized by changing the moment of momentum, which is transmitted to the driven and driving elements of the coupling and to the associated devices va, causing a change in their moment of momentum.

If the torque exceeds the resistance moment on the driven shaft 2, both shafts 1 and 2 rotate at the same frequency. When exceeding the moment of resistance to the rotation of the shaft 2

on the side of the devices associated with it with respect to the torque generated by the forces of inertia of centrifugal weights 4, the nature of the movement of the driven shaft 2 and the transmitted torque will be periodic.

Two centrifugal weights, located on opposite sides of the axis of rotation, ensure, at different frequencies of rotation of the driving and driven shafts, the frequency of their mutual oscillations equal to 180 ° of their relative angular rotation, which, all other conditions being equal, in comparison

0 with a known device, reduces the amplitude of the torsional vibrations of the shafts, which creates a more stable rotation of the driven shaft with its smaller periodic angular deviation relative to the drive shaft. The load on the driven link depends on the rotational speed of the driven and driving links relative to each other.
