Description

(54) ELASTIC CLUTCH

I

The invention relates to mechanical engineering.

Known elastic couplings containing d | Le half-coupling, between which are installed elastic elements of rubber | 1.

However, in these clutches, the resilient elements are subject to rapid employment.

The elastic clutch is known, containing concentric located leading and poor coupling halves and elastic between each other, interacting with the packages and flat springs and the surface of the coupling halves {2 |.

This device is nanba; 1e blinknm to the inventor of the technical essence and the achieved result

The drawback of the device is that it does not ensure the transmission of different torque along two well driven shafts.

A distinctive feature of the clutch sleeve is that the coupling half is made in the form of two elements associated with the corresponding shaft, and the drive coupling half is made in the outer shaft, mounted on one driven shaft and has an annular protrusion on the end face. packages of flat springs installed 8 pvza,

available in the annular protrusion of the drive half coupling.

One of the elements of the driven half coupling vypolyyen 6 vnde glass, and the other in the form of a hub.

One nz of the driven half coupling elements is made in the form of a driven shaft.

In addition, one of the driven shafts can be made hollow, and the other is mounted inside it.

Such an implementation does not ensure the elimination of deficiencies of the known construction.

FIG. 1 shows the described coupling in section; on fng. 2 - section A-A of FIG. I; pas figs. 3 - a coupling in which the shaft performs the functions of the driven half coupling; on fng. 4 - coupling, transmitting torques in one direction; on fng. 5 - clutch in working condition.

Claims (2)

The clutch contains the driven half coupling in vnde two elements 1 n 2 rigidly fixed on the shafts 3 and 4 with the help of keys 5 n 6, freely mounted on the driven shaft 4, for example, on. the sliding bearing of the driving element 7, which is a dnsk with a hub and a cup 8, on which packages of spring plates 9 are attached, projecting relative to its outer and inner surfaces (the mounting of packages of spring plates to the cup may be different, therefore not shown) cylindrical fingers 10, located both from the outer and from the inner surfaces of the cup 8 and in contact with the working surfaces of the elements of the driven coupling half 1 and 2, as well as the sleeve II with the locking screw 12. The role of the elements and two coupling halves 1 vypol a cylindrical surface of the shaft 4. The output shaft 3, the clutch may be formed hollow, and the shaft 4 is mounted inside the first. The clutch works as follows. The torque from the driving element 7 to the elements of the driven coupling half 1 and 2, and successively to the shafts 3 and 4, is transmitted by deforming the spring plates 9 fixed on the cup 8 and compressing the rubber fingers 10 when rolling and wedging them with the contacting surfaces: cup 8 (outer surface) and driven half coupling 1, as well as cup 8 (internal surface) and driven half coupling 2. In a simplified design, rubber pins 10 located on a smaller diameter are wedged between the inside surface of the glass 8 and the front Depending on the external resistance, the spring plates and rubber fingers are deformed not exactly as KOBO, since they are located on different diameters, therefore, the torques on the driven shafts will be different. By making the drive element in the form of a disk with a hub and a cup, on which packages of spring plates are fixed, projecting relative to its surfaces and the arrangement of rubber fingers from both the outer and inner surfaces of the cup, with sufficient simplicity of design, different opposite sides. The execution of hollow shafts from the driven shafts cnq facilitates the transmission of torques to one side. The design of the clutch is simplified by using the surface of the shaft on which the driving member is mounted, as the field at the clutch. Claims of the invention The elastic coupling comprising concentric drive and driven coupling halves and elastic cylindrical fingers mounted between them, interacting with flat spring packages on the coupling half surfaces, in order to transfer different magnitudes of torques to two driven shafts, the half coupling half is made in the form of two elements connected with the corresponding shaft, and the half coupling half is made in the form of a disk, freely mounted on one of the driven shafts and having an annular socket n on the end face, wherein the flat springs packets in the slots having a collar with a leading half of the coupling. 2. The elastic coupling according to claim I, characterized in that one of the elements of the driven half-coupling is made in the form of a glass, and the other in the form of a hub. 3. The coupling coupling according to claim 1, characterized in that, in order to simplify the construction, one of the elements of the driven coupling half is made in the form of a driven shaft. 4.
