Abstract

674,340. Couplings. BRITISH THOMSONHOUSTON CO., Ltd. Nov. 9, 1949 [Nov. 17, 1948], No. 28734/49. Class 80 (ii). [Also in Group XXVI] A vibration damping mounting for the blades 2 of a fan, not shown, upon a fan shaft 1 comprises a resilient torque conveying sleeve 4 of natural or synthetic rubber deformed between the shaft and a hub 3 to which the blades are secured, an annular sleeve head 8 engaging a complementary shaft groove 7, and radial and tapered sleeve flanges 9, 11 engaging hub faces 10, 13 to prevent relative axial shaft to hub movement during fan operation. An end wall 15 prevents collapse of the flange 11. In a modification to increase the torque carrying capacity, the shaft, sleeve and hub may have complementary flattened portions.
