Abstract

814,062. Torsional vibration dampers. HOLSET ENGINEERING CO. Ltd. (Sehwitzer Corporation). Oct. 17, 1957, No. 32414/57. Class 108(3) A torsional vibration damper having an elastic damping annulus mounted between a driving member and a concentric inertia member has a plurality of axially directed, circumferentially spaced vanes constituting an air pump which induces the circulation of cooling air alongside the annulus. Vanes 6, Fig. 1, mount rim 7, carrying rubber annulus 9 and inertia ring 10, on spokes 2 of driving member 1 and drive air round both sides of inertia ring 10, air gap 8 being provided between rim 7 and pulley 4. Radial and axial cooling grooves or pins 11, 12 are provided in inertia ring 10. Fig. 2 shows an embodiment in which vanes 103 mount rim 104, rubber annulus 106 and grooved inertia ring 107 on disc-like driving member 102. Fig. 3 shows a driving plate 201 having a pressed rim 202 which carries rubber annulus 203 and grooved inertia ring 204. Vanes 205 are formed from the driving plate by stamping and pressing operations, the holes 206 left by vanes 205 allowing air circulation. In all the foregoing embodiments the ring of the driving member and the inertia ring may have their adjacent faces respectively concave and convex to prevent axial displacement. In Fig. 6, U-shaped rubber annulus 302 mounts inertia ring 303 and clamping-plate 304 on driving-disc 301. Slots 306 in flange 305 form cooling vanes and pump air in the direction of arrow A. Plate 308 covers radial grooves 307 through which cooling air flows as the damper rotates.
