  • Publication number: 20080081703
    Abstract: A universal joint includes a spider, first and second yokes drivingly interconnected by the spider, a plurality of bearing cups and a plurality of retaining members. The first yoke includes spaced apart arms with apertures extending through each arm. The apertures are coaxially aligned with one another and include a circumferential groove spaced apart from an edge of the arm. Each bearing cup is positioned within one of the apertures and in receipt of one of the trunnions. A portion of each bearing cup is positioned in communication with a corresponding groove. Each retaining member is operable to complement the size and shape of the corresponding groove, bearing cup and aperture such that each retaining member couples one of the bearing cups to its associated arm.

  • Publication number: 20070087847
    Abstract: A power transmission device includes a housing, first and second shafts and a generally tubular boot. The housing has an aperture that at least the first shaft passes through. The first and second shafts are coupled together through a splined connection causing the shafts to rotate with one another while allowing axial translation between the shafts. The boot includes a first end engaged with the first shaft and a second end engaged with the second shaft. The first end of the boot includes a flange having an insert located therein. A portion of the first end biasedly engages the first shaft thereby eliminating the need for a clamp previously required.

  • Publication number: 20050085305
    Abstract: A boot seal for a mechanical joint with a rotary joint member. The boot seal includes a flexible body portion and a flange end that is coupled to an end of the body portion. The flange end includes a flange seal portion, which is configured to seal against the joint member in an axial direction, and an annular lip that extends circumferentially about the seal portion and shields the flange seal portion from debris and moisture.
