Description

one

The invention relates to mechanical engineering and can be used to transfer torque from one shaft to another with large fluctuations in load and misalignment of the connected shafts.

A known coupler with elastic dynamic connections, containing two flange coupling halves and levers, are masses that are articulated with each other and with the coupling halves and act as coupling.

However, when transmitting the torque during the start-up period under the action of large loads, the dynamic link arms, being pulled into the straight line, rigidly transmit the rotational moment, thereby decreasing the reliability of the coupling operation. This dramatically increases the load on the pivot fingers of the hinge levers.

At maximum revolutions, the strain angle approaches the limiting value, and the elastic characteristic of the clutch is tightened.

The purpose of the present invention is to improve the starting characteristics and increase reliability.

For this, the coupling is provided with elastic rings arranged concentrically one relative to the other and clamped ends in the flanges of the coupling halves, with the levers being masses located between the rings.

In addition, elastic rings can be made either in variable sections, or split, or grooved, or in a wave-like profile. The elastic characteristic of the coupling will depend on the shape of the ring.

FIG. 1 shows the scheme of the proposed coupling and its section along A-A; in fig. 2-coupling scheme at the limiting minimum angle of deformation; in fig. 3 is a diagram of the coupling at the maximum maximum deformation angle with a ring of a wave-like profile; in fig. 4 shows a coupling scheme at the limiting minimum deformation angle with a ring of a wave-like profile.

The coupling contains two flange plugs 1, connected by elastic dynamic connections 2, performed, for example, in the form of levers — masses hinged on fingers 3, and elastic rings 4 and 5, for example

undulating profile located between the coupling halves and concentric relative to each other. The ends of the rings are clamped in the flanges of the coupling half.

In the initial period of rotation of the levers -

masses 2 are stretched and at the limiting (maximum) angle of deformation interact with the ring 5, deforming it. Torque is transmitted by ring elasticity. With increasing rotational speed

under the action of centrifugal forces, the levers are thrown to the periphery, unloading the elastic ring. Between the coupling halves, an angle is established proportional to the speed of rotation of the mass levers, the moment of friction and the transmitted torque.

With a further increase in the rotational speed at maximum revolutions or at idle mode, the levers 2 are thrown at a larger radius to the periphery, and at the limiting (mivimal) angle of deformation, the coupling elements interact with the ring 4, deforming, and the torque is transmitted by the elasticity of the ring.

When the load changes, the angle of relative rotation of the half couplings and the position of the levers relative to the axis of rotation of the levers, the ends of which are the shaft, is fixed on the fingers of the half couplings. In this case, at the limiting angles of deformation, the levers interact with the rings, and the elastic characteristic of the coupling in this case is determined by the elasticity of the rings.

When using a centrifugal counter coupling (for transferring the reverse moment), the coupling can have only one ring 5, with which the centrifugal links interact when transferring the forward moment at: maximum strain angle and centrifugal first distortion at the minimum strain angle.
