    • 专利摘要:
    A highly-resilient shaft coupling includes a hub for rotating about a longitudinal axis, a drive ring, a resilient ring assembly including two axially-continuous circular ring parts bearing radially on the hub. Each ring part includes elastomeric ring sectors and ring sector plates adhered to opposite axial ends of each elastomeric ring sector. An elastomeric ring sector of one circular ring part spans parts of two elastomeric ring sectors of the other ring part. A drive ring drivingly interconnects the hub and the resilient ring assembly at one axial end thereof. Fastener means secure together the ring sector plates at one axial end of each of the two circular ring parts, in a confronting relation. Passageways for cooling air extend between the ring sectors which are secure together. A coupling part is secured to one of the ring sectors at the end which is opposite the drive ring.

    This invention relates to elastic couplings for connecting shafts.
    The aim of the invention is to reduce the radial dimensions of reducing the inertia of the coupling.
    Figure 1 schematically shows the proposed coupling, axial incision; FIG. 2 shows the location of the sector in the annular elastic element; FIG. 3 section aa in figure 2 „
     The elastic coupling includes a flange | Zolumuftu 1 and a semi-clutch 2 with a hub | 3, connected to the shaft with at least two coaxially arranged and supported by a bearing 4 on the hub 3 by annular elastic intermediate elements 5 and 6, each of which is made in the form of two metal disks 7 and 8, made of composite of several annular sectors 9., with rubber ring 10 vulcanized to them, made of the corresponding number of sectors 11. The outer diameter of metal disks 7 and 8 is large, m outer diameter of the rubber ring 10.
    On the outer surfaces of the metal disks 7 and 8 on the periphery, annular protrusions 12 and 13 are made, while metal disks of adjacent annular intermediate elements facing one another are interconnected by threaded elements 14 along the outer diameter, and the sectors of each intermediate element 5 or 6 are located one relative to the other with gaps 15 between their radial surfaces. In this case, the sectors of two adjacent annular intermediate elements are displaced relative to each other in the circumferential direction by an amount equal to half the sector pitch, and on the inner surfaces of the metal disks facing one another adjacent annular intermediate elements there are radial annular projections 16 and 17 in contact with the outer surface hub 3 coupling half 2.
    The sliding bearing 4 is located between the hub 3 of the half coupling 2 and the annular protrusions 16 and 17 of the metal disks 8. The parts of the annular projections are located in the circumferential direction at an equal distance from one another. On the surfaces of metal disks 8 facing one another, adjacent annular intermediate elements 5 and 6, annular grooves 18 are formed to form an annular cavity for the passage of cooling air.
    Since the sectors of two adjacent annular prom. Of intermediate elements 5 and 6 are displaced relative to each other in the circumferential direction and interconnected, a single annular intermediate element is formed, which can consist of three or more of annular elements, each of which
    is supported on the hub by means of a bearing
    The clutch works as follows.
    The torque is transmitted, for example, from coupling half 1, successively to elastic annular intermediate elements 6 and 5, and to coupling half 2.
    During the operation of the coupling, air located in the annular cavity between adjacent annular intermediate elements is ejected from the coupling under the action of centrifugal force through the through slots 20, thus forming a forced air flow, which facilitates cooling of the intermediate annular elements.
    Thus, by virtue of this embodiment, the radial dimensions and the inertia of the coupling are reduced in comparison with the known construction.
