摘要： A tappet assembly including an outer cup having a substantially cylindrical side wall, an annular lip portion disposed at a first end of the side wall, and an annular ledge disposed on the side wall, the annular ledge being disposed in a plane that is transverse to a longitudinal center axis of the tappet assembly. An inner cup includes an annular lip extending outwardly therefrom and a pair of shaft apertures, and is disposed in the outer cup so that the lip abuts the annular ledge of the outer cup and is non-rotatably fixed thereto by the annular lip of the outer cup which abuts the lip of the inner cup. A shaft is received in the shaft apertures, and a roller tappet is rotatably received on the shaft such that a portion of the roller tappet extends axially outwardly beyond the annular lip portion of the outer cup, and an alignment device formed in the outer cup.

摘要： A follower mechanism including an outer cup having a substantially cylindrical side wall, an annular lip portion disposed at a first end of the side wall, an annular ledge disposed on the side wall, the annular ledge being disposed in a plane that is transverse to a longitudinal center axis of the follower mechanism, and an anti-rotation device disposed on the annular ledge. An inner cup includes an annular lip extending radially-outwardly therefrom and a pair of shaft apertures, the inner cup being disposed in the outer cup so that the lip abuts the annular ledge of the outer cup as well as the anti-rotation devices so that the inner cup is non-rotatable with respect to the outer cup. A shaft is received in the shaft apertures, and a roller follower is rotatably received on the shaft.

摘要： A thrust bearing assembly comprises a cage including an annular portion. A first flange extends axially from an inner peripheral edge of the annular portion, and a second flange extends axially from an outer peripheral edge of the annular portion. A first plurality of roller pockets are defined by the annular portion, the first roller pockets of the first plurality of roller pockets being spaced evenly about the annular portion. A second plurality of roller pockets are defined by the annular portion, the second roller pockets of the second plurality of roller pockets being evenly spaced about the annular portion so that each second roller pocket is disposed between adjacent first roller pockets.
