899,309. Flexible shafts; shaft couplings ; resiliently mounted race-rings. OPEL A.G., ADAM. Aug. 31, 1960 [Sept. 2, 1959], No. 29996/60. Class 80 (2). [Also in Group XXXIV] To dampen the torsional and flexural oscillations of a shaft 16, Fig. 1, normally straight but held bowed for use as a motor car propeller shaft by bearings at its ends, bosses 53, Figs. 2, 6, on coupling flanges at each end of the shaft carry surrounding tubes 57 which compress sleeves 56 of rubber &c. on to the shaft. Each surrounding sleeve 57, shown in the disassembled position in Fig. 6, is pushed on to a knurled surface 55 on the boss 53, which is in turn pushed on to splines 52 at the shaft ends, the reduced end 59 of the surrounding sleeve 57 compressing the rubber 56 during assembly. The boss 53 is secured by bolts 23 to the adjacent driving (or driven) shaft 20. Bearings 38, 39, controlling bending vibrations in the shaft at its second mode critical speed or a sub-harmonic of this speed, have their inner races secured to the shaft by sleeves of rubber &c. 48, their outer races being resiliently mounted within a non-rotary protecting tube 17 (see Group XXXIV). Specification 839,292 is referred to. |
