摘要： A cam roller pin is rotationally fixed and defines a pin axis around which a cam roller is configured to rotate and apply a load at a load zone at a radially outer and lower end of the pin. The pin includes a reservoir configured to receive lubricant for lubrication of the cam roller rotating on the pin, a first lubricant path extending radially inward from the reservoir, a second lubricant path extending from the first lubricant path to a second lubricant path outlet, and a third lubricant path extending from the first lubricant path to a third lubricant path outlet.

摘要： An axial retainment system for a shaft is provided. The axial retainment system includes a cylindrical body extending from an outboard end to an inboard end thereof, and a swaged ridge extending radially outward from the cylindrical body proximate the outboard end. The swaged ridge has an outboard axial surface facing toward the outboard end and extending radially outward and terminating at a radially outward facing circumferential surface. The swaged ridge has an inboard axial surface facing toward the inboard end and extending radially outward from the cylindrical body and terminating at the radially outward facing circumferential surface. The outboard axial surface of the swaged ridge is recessed axially inward from the outboard end of the shaft. The inboard axial surface of the swaged ridge is swaged against, conforms in shape to, and is compressed against a component to be axially retained on the shaft.

摘要： A clip for a switchable roller finger follower that includes a retainer for a hydraulic lash adjuster, and an anti-rotation feature that prevents rotation of a coupling pin is provided. The clip includes a first leg arranged adjacent to a dome-shaped recess on a bottom surface of an outer lever of the switchable roller finger follower that includes a retainer for the hydraulic lash adjuster, and a second leg of the clip includes an anti-rotation bar that extends laterally across a part of the coupling pin and prevents rotation of the coupling pin. A switchable finger follower with the clip is also provided.

摘要： A cam follower assembly includes a shaft having a body defining a flanged head having an outer bearing surface extending therefrom. An outer ring is positioned around the shaft thereby forming an annular space there between. A plurality of rollers is positioned in the annular space. A channel extends through the shaft and branches radially outward at an outlet to communicate with the annular space. A lubrication assembly is positioned in the shaft and includes a pressurizing device located upstream of a lubrication reservoir and a metering device positioned downstream of the lubrication reservoir. The lubrication reservoir is in fluid communication with the outlet. The lubrication assembly includes a membrane positioned downstream of the lubrication reservoir. A piercing device is positioned proximate the membrane to pierce the membrane and release a lubricant from the lubrication reservoir.

摘要： A follower mechanism movable along an axis within a bore including an alignment groove. The follower mechanism includes a bucket with a cylindrical inner surface and a cylindrical outer surface, and a yoke positioned at least partially within the bucket, the yoke including a bottom wall and two opposed sidewalls depending upwardly therefrom, each sidewall defining a shaft aperture. A shaft with first and second ends is received in the shaft apertures, and a roller follower is rotatably received on the shaft such that a portion of the roller follower extends axially outwardly beyond the bucket.

摘要： A mechanical system forms a cam follower or a rocker arm. The mechanical system comprises: a support element, a pin extending between two opposite ends along a first axis and supported by the support element, and a roller adapted to receive the pin. The roller being mounted on pin, movable in rotation relative to the pin around the first axis and adapted to roll on a cam. The support element comprises two separate parts, generally semi-cylindrical, each having a contact face, in contact with one other, and a holding feature for maintaining parts assembled together.

摘要： A coupling pin anti-rotation arrangement is provided for a switchable roller finger follower within a valve train of an internal combustion engine. The coupling pin, located on one of the levers, has a first locking surface, and includes at least one coupling pin-side anti-rotation flat; the other lever, with a second locking surface, is configured with at least one lever-side anti-rotation flat. The at least one lever-side anti-rotation flat slidably guides the at least one coupling pin-side anti-rotation flat such that the first locking surface is aligned with the second locking surface throughout longitudinal displacement of the coupling pin within a coupling pin bore. The coupling pin anti-rotation arrangement is adaptable to various switchable roller finger follower designs that incorporate different valve lift strategies and lever configurations.

摘要： A cam follower roller assembly has a shaft insertable into a roller. The shaft has a zerk in communication with the channel wherein lubricant can be added to the assembly. The design of the assembly in one embodiment is such that a larger shoulder to shaft radius stabilizes the shaft and limits the shaft from rocking or elongating within a mounting hole. When utilized in the application of a loading mechanism and carriage assembly for trash collection vehicles, one embodiment of the cam follower roller assembly provides greater life and easier serviceability.
