Description

The invention relates to mechanical engineering, in particular, to elastodynamic Couplings, and can be used to connect shafts and transmit torque with the possibility of reversing in machines and mechanisms, as well as to compensate for misalignments of connected shafts and deform the resulting vibrations and dynamic loads.

The purpose of the invention is to expand the operational capabilities and increase the carrying capacity.

Figure 1 shows the elastic centrifugal coupling, a cross-section; figure 2 - g section aa in figure 1; on fig.Z - section bb in figure 1.

The elastic-center coupling consists of a leading coupling half, made in the form of a hub with grooves on the outer surface, and a driven coupling half 2 in the form of a hub with a rim 3.

Lead 1 and slave 2 coupling halves are interconnected by means of spring elements 4. made {-shaped, with loops at the ends. On the intertwined cylindrical surfaces of the coupling halves there are grooves in which fingers 5 are installed, the loops of the ends of the spring elements 4 cover the fingers 5 rotatably, located on the rim 3 of the driven coupling half 2, and the middle loop-shaped sections of the spring elements 4 cover the fingers 5 on the leading coupling half 1.

Additional spring elements 4 located coaxially with each other can be installed in the coupling. At the places of installation of spring elements 4 on the pallet.

Cach 5 between them are placed metal pads 6,

The clutch operates as follows. In the static state or when the clutch is operating. During load the spring elements.

4 is in the undeformed state, the angle A between the branches of the f-shaped spring element 4 remains constant,

When a torque is applied to the leading coupling half 1 and when there is a moment of resistance on the driven coupling half 2, the torque from the leading coupling half 1 is transmitted through the fingers 5 to the middle sections of the spring elements 4, then to the ends of the elements 4 mounted on the fingers

5 in the grooves of the rim 3 of the driven half coupling 2. Thus, the torque is transmitted to the driven coupling half 2. The angle "between the branches of the if-shaped spring elements is reduced, the Torque through the f-shaped spring elements 4 is transmitted in two ways. Depending on the direction of rotation, some branches of element 4 work on stretching, while other branches work on compression. The damping and elastic properties of the branches of the spring elements 4 increase the damping and compensation properties of the coupling. The axial misalignment of the connected shafts due to the elasticity of the spring elements can be up to 10 mm, the angular misalignment is up to 1B °.
