MECHANICAL SYSTEM FORMING A CAM FOLLOWER OR A ROCKER ARM, INJECTION PUMP OR VALVE ACTUATOR COMPRISING SUCH A MECHANICAL SYSTEM AND METHOD FOR MANUFACTURING SUCH A MECHANICAL SYSTEM

摘要

A mechanical system forms a cam follower or a rocker arm and includes a support element, a pin extending between two opposite ends along a first axis and supported by the support element, and a roller mounted on the pin, movable in rotation relative to the pin around the first axis and adapted to roll on a cam. The support element includes a first axial abutment feature blocking the translation of a pin assembly including at least the pin, in a first direction parallel to a second axis perpendicular to the first axis. The mechanical system additionally includes an insert inserted in the support element and supporting the pin opposite the first axial abutment feature, wherein the first axial abutment feature protrudes outside a cavity delimited by the support element and receiving the pin.
