Abstract

579,226. Flexible shaft couplings. DUNLOP RUBBER CO., Ltd., and HICKMAN, J. C. Oct. 10, 1944, No. 19434. [Class 80 (ii)] A flexible coupling comprises a ring of segmental metal U-section elements 1, Figs. 1 and 2, secured to the flange 13 of a shaft 15, and interposed elements 3, secured to the elements 1 by strips of rubber 4, bonded to each of the elements, and bolted to the flange 14 of a shaft 16. In a modification the U-section elements may be formed in two parts 1, 2, Fig. 4, connected together so as to compress the rubber strips. In another arrangement, the elements 3 are formed with tongues 11, Fig. 5, which engage with slots 12 formed in the elements 1, so as to limit the relative circumferential movement between the elements. In another arrangement for limiting this relative movement, the elements 3, Fig. 7, are formed with tongues 11 which move in the space between the parts 17 of the elements 1. In a further modification, the shaft flanges are connected by U-section elements 1, Fig. 9, and an interposed metal strip 3, secured to the elements 1 by bonded rubber strips 4.
