Filed: 1955-04-25
Abstract: 780,527. Securing wheels on shafts. DODGE MANUFACTURING CORPORATION. April 25, 1955, No. 11841/55. Class 80 (2). Transmission of circumferential tension through a split cast iron bush 16 securing a toothed or plain wheel 13 on a shaft 11, is prevented by either relieving appropriate sides 31, 31<SP>1</SP> of blind, plain recesses 25 in the bush housing screws 24, 24<SP>1</SP> screwing in complementary threaded recesses 25 in the wheel, to draw the externally tapered surface of the bush into the complementary internal surface of the wheel, or by splitting the bush at each recess. Tangential pressure under drive torque between either screw and the bush in the tensile direction is thereby avoided, and the bush is subjected by the torque to circumferential compression only. In Figs. 1 and 3 the internal cylindrical surface of the bush 16 has a way engaging a key 19 or spline on the shaft, and the unthreaded blind recesses 26 in the bush 16 are both relieved circumferentially on the same remote side 31, 31<SP>1</SP> of the key to prevent transmission of drive torque between the screws 24 and those sides of the recesses 26. Thus for torque transmission in one sense (e.g. clockwise from wheel to shaft), the portion of the bush between the screw 24<SP>1</SP> and key 19 is in circumferential compression, the remainder being unstressed circumferentially, whilst in the opposite sense, only the portion between the screw 24 and key 19 is compressed. In Figs. 7-9, not shown, one screw 24 coincides with the single split 18 of the bush and is thus incapable of transmitting tension thereto, whilst the recess for the other screw is relieved on one or both sides. In Figs. 10-12, not shown, no recess is relieved but the bush is split at two diametrically opposite points coinciding with the screws. To facilitate drawing the wheel off the bush, a single oppositely acting screw 33 may be screwed into a threaded hole in the bush and bear at the end of a complementary blind recess in the wheel. Specification 592,912 is referred to.
