1,143,522. Shaft couplings; resilient couplings; universal joints; securing parts on shafts. METALLSCHLAUCHFABRIK A.G. 17 Jan., 1967 [26 Jan., 19661, No. 2408/67. Heading F2U. In a rigid or resiliently flexible coupling or universal joint disposed between two at least approximately coaxial shaft ends 1, 2 and comprising bosses 4, 5 mounted on the shaft ends and connected together by power transmitting means, each of said bosses comprises two axially separated portions 6, 7 clamped together by bolts 12 and thereby connected to the corresponding shaft end, 1, by way of conical rings 15, 16, the boss portion 6 supporting said power transmitting means and the boss portion 7 providing an additional power transmission path between the shaft 1 and the boss portion 6. In the rigid coupling shown, the thickness of the boss portions 6, 7, 9, 10 is such that they can be individually inserted through the gap 3 between the shaft ends 1, 2 thereby eliminating the need for displacement of the shaft ends during coupling installation or removal. The conical rings 15, 16 preferably have at least one cut to assist fitting. The boss portions 6, 9 are spaced by a ring 21 and connected together by bolts 22. In Fig. 2 (not shown), the poss portions 6, 9 are connected by resilient rubber, or rubberclad steel, pins arranged radially outwardly of the boss portions 7, 10 to permit assembly without shaft displacement. In Fig. 3 (not shown), the boss portions 6, 9 are connected by a cross (33) to form a Hooke's joint. The boss portions 6, 9 have alternating axially extending claws embracing the arms of the cross via intermediate layers (34) comprising e.g., elastic material such as rubber and retained by closure members bolted to the cross arm ends. The layers (34) permit small radial shaft misalignment. In Figs. 6, 7 (not shown) the power transmitting means between the boss portions 6, 9 comprises an annular, parallelly or helically corrugated, flexible, single or multi-walled tube radially clamped either between the boss portions on each shaft end, the boss portion 6 being desirably radially cut into sections and retained together by a spring ring, or between the boss portion 6 and a conical ring further to and contacting the corresponding conical ring 15 and desirably radially cut into sections and retained together by a spring ring. This construction permits axial, radial and angular misalignment. |
