Abstract
The coupling of the present invention is used for joining two shafts together. The coupling comprises a first hub and a second hub which are joined together by a central web located therebetween. Both the first and second hubs include an inner bore extending therethrough and an outer tapered surface. The bores of the first and second hubs are sized to receive the two shafts which are to be connected. A pair of nuts, each having a threaded tapered bore extending therethrough are threaded over the outer tapered surfaces of the two hubs until the nuts exert an inner radial force on the hubs, thereby causing the hubs to frictionally grip and hold the shafts against movement relative to the coupling body. The coupling body may be longitudinally divided into two separate halves which embrace the opposite sides of the shafts and which are held together by the nuts which surround the tapered hub portions thereof.
