Abstract
1,172,469. Universal joints. FALK CORP. 24 July, 1968 [15 Aug., 1967], No. 35238/68. Heading F2U. In a universal joint comprising an annular U-shaped cross-section nylon card reinforced rubber element 15 secured at its radially outwardly extending side walls 16 by tapered L- shaped cross-section clamping rings 18 bolted at 22 to plain surfaces 14 of flanged hubs 12 keyed to driving and driven shafts 10, 11, failure at the connections between the rubber element 15 and hubs 12 is avoided by the side securing walls 16 of the rubber element 15, having a uniform thickness (t) before assembling (Fig. 4, not shown), being permanently deformed on assembly, but with the reinforcing cords 17 free from rupture, by the inner edge of radial legs 19, of the rings 18, which legs 19 are tapered outwardly such that axial legs 21 of the rings protrude an amount corresponding to the thickness of the rubber walls 16 which are thus unstressed at their radially outer edge, the arrangement permitting a maximum clamping rupture-free connection between the rubber element 15 and flanged hubs 12. The frictional clamping effect between the legs 21, of the rings 18, and the surfaces 14 of the hub flanges 13 relieves the bolts 22 from the driving torque shear load and resultant bending. In other arrangements (not shown) the tapered clamping surface may be alternatively formed on the hub flanges 13, or, on both the hub flanges 13 and clamping rings 18. Various formulae are given for determination of the tapered clamping angle for maximum clamping pressure free from rupture of the annular rubber element.
