Description

The utility model relates to mechanical engineering, namely, elastic plastic couplings used in the transmission of rotational motion from a drive shaft to a driven one with simultaneous compensation of axial, angular and radial displacements of the connected shafts.

Known semi-rigid disc clutch containing two half-couplings interconnected by a disk clamped with bolts, made of spring or corrosion-resistant steel [GOST 26455-97].

Known elastic coupling containing two coupling halves, elastic element with reinforced discs, rigidly connected to the coupling halves with fingers [US Pat. 571636 USSR, MPK F16D 3/48, F16D 3/78. Elastic coupling / Shmakov Yu.M., Kochurov A.V. - No. 2110048/08; dec. 03/03/1975; publ. 09/05/1977. Bull. No. 33].

The disadvantage of these couplings is the relatively low damping capacity.

Known elastic coupling with an intermediate disc, which contains two coupling halves and an intermediate disc between them, while the coupling halves are connected to the intermediate disc with fingers made of rubber [GOST 25021-81].

The disadvantage of this clutch is the impossibility of transmitting significant torques, as well as fatigue failure of the intermediate disk.

The objective of the utility model is to create a device that eliminates the above disadvantages while maintaining the technical characteristics of the product.

The technical result - an increase in damping capacity and the possibility of transmitting more torque is achieved by using an elastic disk-type element, which is a package that includes a certain number of disks, consisting of alternating layers of rubber and cord fabric with an equal ratio of their widths.

In FIG. 1 shows a finger clutch with an elastic element of the disk type, in Fig. 2 - an elastic element of a disk type, which is a package that includes a certain number of disks, consisting of alternating layers of rubber and cord fabric with an equal ratio of their widths, D - the diameter of the circle passing through the centers of the holes for the fingers, B - the total width of the elastic element.

The clutch contains two half-couplings 1 and 2, an elastic element of disk type 3, connected to the half-couplings 1, 2 by means of fingers 4. width.

The clutch works as follows.

The torque is transmitted through the half-clutch 1 to the elastic element of the disk type 3 by gap-free installation of four fingers 4 in them and then through the elastic element of the disk type 3 to the half-clutch 2 with the help of four fingers 4 associated with it.

Due to the presence of an elastic disk-type element, which is a package that includes a certain number of disks consisting of alternating layers of rubber and cord fabric with an equal ratio of their width, the coupling can compensate for axial, angular and radial displacements of the connected shafts, as well as transmit large torques due to the use of layers made of cord fabric, which has higher strength properties compared to rubber. At the same time, the use of an elastic element, which is a package, increases the reliability of the clutch, since if one of the disks fails, the load is distributed to the others.

Thus, the proposed pin clutch with an elastic element of the disk type allows you to transfer large torques, providing a damping effect.
