ELASTIC COUPLING FOR CONNECTING SHAFTS

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.
