Abstract: A universal joint includes a cross operably connected therein, the cross comprises a body having four trunions extending therefrom along two mutually perpendicular lines, a lubrication network in the body and the trunions to provide lubrication to the cylindrical outer bearing surface of the trunions, the network includes a plurality of branches in communication with and terminating in a counterbore provided internally in each of the trunions, each counterbore having a cylindrical inner surface coaxial with the cylindrical outer bearing surface of the trunions, the counterbore is open at its end opposite the branches, a flow metering member having at least one metering orifice therethrough fixedly disposed within each of the counterbores to meter lubricant flowing from each of the branches downstream into the counterbore and to the bearing means and various bearing surfaces associated therewith including the cylindrical outer bearing surface of the trunions.

Abstract: A power drive yoke adapted for quick attachment to and disconnection from an output drive shaft of a power drive means comprises a yoke having a hub formed thereon. The hub has a centrally disposed longitudinally extending bore for accepting a portion of the output drive shaft. The output drive shaft is mechanically interconnected to the yoke to rotationally drive the yoke by passing means. An annular groove is provided on the portion of the output shaft and is accepted within the bore in the hub. The hub is provided with at least two generally parallel bores each tangentially intersecting the bore on its opposite sides. A locking pin is slidably disposed in each of the parallel bores and has a locking surface thereon to engage the annular groove on the output shaft. Means are provided to connect each of the locking pins to substantially simultaneously slidably move the locking pins within the bores into engagement and disengagement with the output shaft at its annular groove.

Abstract: A bearing for receiving a journal comprises a bearing cup and a series of needle bearing elements interposed between the inner surface of the cup and the journal. Means are provided to bias the needle bearing elements into intimate rolling bearing contact with the outer bearing surface of the journal and bearing cup.
