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

This mechanical system (1) forms a cam follower or a rocker arm and comprises a support element (10), a pin (30) extending between two opposite ends (35, 36) along a first axis (X1) and supported by the support element (10), and a roller (40) mounted on the pin (30), movable in rotation relative to the pin around the first axis (X1) and adapted to roll on a cam. The support element (10) comprises first axial abutment means (12) blocking the translation of a pin assembly including at least the pin (30), in a first direction parallel to a second direction (Y1) perpendicular to the first direction (X1).
