Each U-shaped segment is connected to adjacent U-shaped segments by a distal end wall to leave a portion of the spline teeth exposed between each pair of adjacent U-shaped segments. A female spline has a shape complementary to that of a combination of the male spline and insert ring for coupling engagement therebetween.

  • Patent number: 8584342
    Abstract: A method for retaining lubrication in a splined joint comprises the steps of forming a seal between an inward surface of a grease seal cup and a first component, forming another seal between an outward surface of the grease seal cup and a sealing member extending from a second component, and engaging an end portion of the grease seal cup with an end portion of the first component, so that the end portion of the grease seal cup resists axial displacement of the grease seal cup during engagement of the first component with the second component. The grease seal cup of the method has a cylindrical portion integral with the end portion. The cylindrical portion has a tapered annular wall with the inward and outward surfaces. The end portion of the grease seal cup extends radially and inwardly from the cylindrical portion, so that the tapered annular wall is squeezed between the first component and the sealing member.

    Abstract: A motor vehicle 10 includes a hydromechanical powersplit transmission 11 having a hydraulic pump motor unit drive shaft 44 and a gear 76. The shaft 44 and gear 76 are drivingly connected together with a spline connection 160. The spline connection 160 includes an internal spline connector 161 and an external spline connector 162. Each spline connector 161, 162 includes a spline portion 166, 174 and a generally smooth portion 168, 175 adjacent its spline portion. During assembly, generally smooth portion 168 of the internal spline connector 160 engages and guides spline portion 174 of the external spline connector 162 to longitudinally and circumferentially align the spline portions 174 and 166. After assembly, the spline portions 166, 174 and the generally smooth portions 168 and 175 are radially aligned with and engage one another to form a rigid driving connection.

  • Patent number: 8545125
    Abstract: A connection between a shaft and a coupling that preferably involves involute shaped splines is designed to reduce stress from torque applied to the shaft by a drive motor. To avoid stress concentration at the mouth of the coupling on startup, the shaft splines are made to taper from the shaft end down to the spline end. As a result, the initial contact with the coupling splines occurs within the coupling and removed from it mouth. The shaft is allowed to elastically twist in response to the applied torque as the contact area increases with shaft twisting and the contact line moves toward the mouth of the coupling. Some shaft elastic twist occurs without adding stress to the shaft splines until coupling contact is made.
