  • Patent number: 5868517
    Abstract: A shaft coupling structure for male and female shaft components of a vehicular propeller shaft includes a sleeve shaft having a substantially rigid first end, an annular flange formed therearound at a central location at which the sleeve shaft connects to a tube member, and a reduced diameter portion which extends from the flange into the tube portion. A plurality of splines are formed in the axial direction of the sleeve shaft and are interposed between an inner wall of the rigid first end and a stub yoke which is inserted into the first end for co-rotation therewith. Further, a grease cap, or other lubrication device may be provided at an end of the reduced diameter portion. Also, around the reduced diameter portion, between the inner wall of the tube and the outer side of the reduced diameter portion, a vibration damping device, as well as an insertion guide device may be provided for improving smoothness and reducing operational noise for the shaft coupling structure.

  • Patent number: 5674026
    Abstract: A shaft coupling structure for a split type drive shaft comprises an internally splined female shaft, and externally splined male shaft coaxially received in the female shaft to establish a spline-connection. A play suppression member is interposed between the male and female shafts for suppressing play of the male shaft relative to the female shaft and vice versa. The play suppression member includes an elongate member extending in and along an axially extending groove defined between the male and female shafts. A hook portion possessed by the elongate member detachably fixes to one of the male and female shafts. The elongated member also has a biasing structure, which biases the male and female shafts in radially opposite directions.
